Introduction Err bitreich.org 70 i+ Err bitreich.org 70 i+ The use of calendaring and scheduling has grown considerably in the Err bitreich.org 70 i+ last decade. Enterprise and inter-enterprise business has become Err bitreich.org 70 i+ dependent on rapid scheduling of events and actions using this Err bitreich.org 70 i+ information technology. This memo is intended to progress the level Err bitreich.org 70 i+ of interoperability possible between dissimilar calendaring and Err bitreich.org 70 i+ scheduling applications. This memo defines a MIME content type for Err bitreich.org 70 i+ exchanging electronic calendaring and scheduling information. The Err bitreich.org 70 i+ Internet Calendaring and Scheduling Core Object Specification, or Err bitreich.org 70 i+ iCalendar, allows for the capture and exchange of information Err bitreich.org 70 i+ normally stored within a calendaring and scheduling application; such Err bitreich.org 70 i+ as a Personal Information Manager (PIM) or a Group-Scheduling Err bitreich.org 70 i+ product. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The iCalendar format is suitable as an exchange format between Err bitreich.org 70 i+ applications or systems. The format is defined in terms of a MIME Err bitreich.org 70 i+ content type. This will enable the object to be exchanged using Err bitreich.org 70 i+ several transports, including but not limited to SMTP, HTTP, a file Err bitreich.org 70 i+ system, desktop interactive protocols such as the use of a memory- Err bitreich.org 70 i+ based clipboard or drag/drop interactions, point-to-point Err bitreich.org 70 i+ asynchronous communication, wired-network transport, or some form of Err bitreich.org 70 i+ unwired transport such as infrared. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The memo also provides for the definition of iCalendar object methods Err bitreich.org 70 i+ that will map this content type to a set of messages for supporting Err bitreich.org 70 i+ calendaring and scheduling operations such as requesting, replying Err bitreich.org 70 i+ to, modifying, and canceling meetings or appointments, to-dos, and Err bitreich.org 70 i+ journal entries. The iCalendar object methods can be used to define Err bitreich.org 70 i+ other calendaring and scheduling operations such as requesting for Err bitreich.org 70 i+ and replying with free/busy time data. Such a scheduling protocol is Err bitreich.org 70 i+ defined in the iCalendar Transport-independent Interoperability Err bitreich.org 70 i+ Protocol (iTIP) defined in [2446bis]. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The memo also includes a formal grammar for the content type based on Err bitreich.org 70 i+ the Internet ABNF defined in [RFC5234]. This ABNF is required for Err bitreich.org 70 i+ the implementation of parsers and to serve as the definitive Err bitreich.org 70 i+ reference when ambiguities or questions arise in interpreting the Err bitreich.org 70 i+ descriptive prose definition of the memo. Additional restrictions Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 5] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ that could not easily be expressed with the ABNF syntax are specified Err bitreich.org 70 i+ as comments in the ABNF. Comments with normative statements should Err bitreich.org 70 i+ be treated as such. Err bitreich.org 70 i+ Err bitreich.org 70 i+2. Basic Grammar and Conventions Err bitreich.org 70 i+ Err bitreich.org 70 i+ The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", Err bitreich.org 70 i+ "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this Err bitreich.org 70 i+ document are to be interpreted as described in [RFC2119]. Err bitreich.org 70 i+ Err bitreich.org 70 i+ This memo makes use of both a descriptive prose and a more formal Err bitreich.org 70 i+ notation for defining the calendaring and scheduling format. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The notation used in this memo is the ABNF notation of [RFC5234]. Err bitreich.org 70 i+ Readers intending on implementing the format defined in this memo Err bitreich.org 70 i+ should be familiar with this notation in order to properly interpret Err bitreich.org 70 i+ the specifications of this memo. Err bitreich.org 70 i+ Err bitreich.org 70 i+ All numeric values used in this memo are given in decimal notation. Err bitreich.org 70 i+ Err bitreich.org 70 i+ All names of properties, property parameters, enumerated property Err bitreich.org 70 i+ values, and property parameter values are case-insensitive. However, Err bitreich.org 70 i+ all other property values are case-sensitive, unless otherwise Err bitreich.org 70 i+ stated. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Note: All indented editorial notes, such as this one, are intended Err bitreich.org 70 i+ to provide the reader with additional information. The Err bitreich.org 70 i+ information is not essential to the building of an implementation Err bitreich.org 70 i+ conformant with this memo. The information is provided to Err bitreich.org 70 i+ highlight a particular feature or characteristic of the memo. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The format for the iCalendar object is based on the syntax of the Err bitreich.org 70 i+ text/directory media type [RFC2425]. While the iCalendar object is Err bitreich.org 70 i+ not a profile of the text/directory media type [RFC2425], it does Err bitreich.org 70 i+ reuse a number of the elements from the [RFC2425] specification. Err bitreich.org 70 i+ Err bitreich.org 70 i+2.1. Formatting Conventions Err bitreich.org 70 i+ Err bitreich.org 70 i+ The elements defined in this memo are defined in prose. Many of the Err bitreich.org 70 i+ terms used to describe these have common usage that is different than Err bitreich.org 70 i+ the standards usage of this memo. In order to reference, within this Err bitreich.org 70 i+ memo, elements of the calendaring and scheduling model, core object Err bitreich.org 70 i+ (this memo), or interoperability protocol [2446bis] some formatting Err bitreich.org 70 i+ conventions have been used. Calendaring and scheduling roles are Err bitreich.org 70 i+ referred to in quoted-strings of text with the first character of Err bitreich.org 70 i+ each word in uppercase. For example, "Organizer" refers to a role of Err bitreich.org 70 i+ a "Calendar User" within the scheduling protocol defined by Err bitreich.org 70 i+ [2446bis]. Calendar components defined by this memo are referred to Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 6] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ with capitalized, quoted-strings of text. All calendar components Err bitreich.org 70 i+ start with the letter "V". For example, "VEVENT" refers to the event Err bitreich.org 70 i+ calendar component, "VTODO" refers to the to-do calendar component, Err bitreich.org 70 i+ and "VJOURNAL" refers to the daily journal calendar component. Err bitreich.org 70 i+ Scheduling methods defined by iTIP [2446bis] are referred to with Err bitreich.org 70 i+ capitalized, quoted-strings of text. For example, "REQUEST" refers Err bitreich.org 70 i+ to the method for requesting a scheduling calendar component be Err bitreich.org 70 i+ created or modified, and "REPLY" refers to the method a recipient of Err bitreich.org 70 i+ a request uses to update their status with the "Organizer" of the Err bitreich.org 70 i+ calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The properties defined by this memo are referred to with capitalized, Err bitreich.org 70 i+ quoted-strings of text, followed by the word "property". For Err bitreich.org 70 i+ example, "ATTENDEE" property refers to the iCalendar property used to Err bitreich.org 70 i+ convey the calendar address of a calendar user. Property parameters Err bitreich.org 70 i+ defined by this memo are referred to with lowercase, quoted-strings Err bitreich.org 70 i+ of text, followed by the word "parameter". For example, "value" Err bitreich.org 70 i+ parameter refers to the iCalendar property parameter used to override Err bitreich.org 70 i+ the default value type for a property value. Enumerated values Err bitreich.org 70 i+ defined by this memo are referred to with capitalized text, either Err bitreich.org 70 i+ alone or followed by the word "value". For example, the "MINUTELY" Err bitreich.org 70 i+ value can be used with the "FREQ" component of the "RECUR" value type Err bitreich.org 70 i+ to specify repeating components based on an interval of one minute or Err bitreich.org 70 i+ more. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following table lists the different characters from the Err bitreich.org 70 i+ [US-ASCII] character set that is referenced in this document. For Err bitreich.org 70 i+ each character, the table specifies the character name used Err bitreich.org 70 i+ throughout this document, along with its US-ASCII decimal codepoint.

Related Memos Err bitreich.org 70 i+ Err bitreich.org 70 i+ Implementers will need to be familiar with several other memos that, Err bitreich.org 70 i+ along with this memo, form a framework for Internet calendaring and Err bitreich.org 70 i+ scheduling standards. This memo specifies a core specification of Err bitreich.org 70 i+ objects, value types, properties, and property parameters. Err bitreich.org 70 i+ Err bitreich.org 70 i+ o iTIP [2446bis] specifies an interoperability protocol for Err bitreich.org 70 i+ scheduling between different implementations; Err bitreich.org 70 i+ Err bitreich.org 70 i+ o iCalendar Message-Based Interoperability Protocol (iMIP) [2447bis] Err bitreich.org 70 i+ specifies an Internet email binding for [2446bis]. Err bitreich.org 70 i+ Err bitreich.org 70 i+ This memo does not attempt to repeat the specification of concepts or Err bitreich.org 70 i+ definitions from these other memos. Where possible, references are Err bitreich.org 70 i+ made to the memo that provides for the specification of these Err bitreich.org 70 i+ concepts or definitions. Err bitreich.org 70 i+ Err bitreich.org 70 i+3. iCalendar Object Specification Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following sections define the details of a Calendaring and Err bitreich.org 70 i+ Scheduling Core Object Specification. The Calendaring and Scheduling Err bitreich.org 70 i+ Core Object is a collection of calendaring and scheduling Err bitreich.org 70 i+ information. Typically, this information will consist of an Err bitreich.org 70 i+ iCalendar stream with one or more iCalendar objects. The body of the Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 8] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ iCalendar object consists of a sequence of calendar properties and Err bitreich.org 70 i+ one or more calendar components. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Section 3.1 defines the content line format; Section 3.2 defines the Err bitreich.org 70 i+ property parameter format; Section 3.3 defines the data types for Err bitreich.org 70 i+ property values; Section 3.4 defines the iCalendar object format; Err bitreich.org 70 i+ Section 3.5 defines the iCalendar property format; Section 3.6 Err bitreich.org 70 i+ defines the calendar component format; Section 3.7 defines calendar Err bitreich.org 70 i+ properties; and Section 3.8 defines calendar component properties. Err bitreich.org 70 i+ Err bitreich.org 70 i+ This information is intended to be an integral part of the MIME Err bitreich.org 70 i+ content type registration. In addition, this information can be used Err bitreich.org 70 i+ independent of such content registration. In particular, this memo Err bitreich.org 70 i+ has direct applicability for use as a calendaring and scheduling Err bitreich.org 70 i+ exchange format in file-, memory-, or network-based transport Err bitreich.org 70 i+ mechanisms. Err bitreich.org 70 i+ Err bitreich.org 70 i+3.1. Content Lines Err bitreich.org 70 i+ Err bitreich.org 70 i+ The iCalendar object is organized into individual lines of text, Err bitreich.org 70 i+ called content lines. Content lines are delimited by a line break, Err bitreich.org 70 i+ which is a CRLF sequence (CR character followed by LF character). Err bitreich.org 70 i+ Err bitreich.org 70 i+ Lines of text SHOULD NOT be longer than 75 octets, excluding the line Err bitreich.org 70 i+ break. Long content lines SHOULD be split into a multiple line Err bitreich.org 70 i+ representations using a line "folding" technique. That is, a long Err bitreich.org 70 i+ line can be split between any two characters by inserting a CRLF Err bitreich.org 70 i+ immediately followed by a single linear white-space character (i.e., Err bitreich.org 70 i+ SPACE or HTAB). Any sequence of CRLF followed immediately by a Err bitreich.org 70 i+ single linear white-space character is ignored (i.e., removed) when Err bitreich.org 70 i+ processing the content type. Err bitreich.org 70 i+ Err bitreich.org 70 i+ For example, the line: Err bitreich.org 70 i+ Err bitreich.org 70 i+ DESCRIPTION:This is a long description that exists on a long line. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Can be represented as: Err bitreich.org 70 i+ Err bitreich.org 70 i+ DESCRIPTION:This is a lo Err bitreich.org 70 i+ ng description Err bitreich.org 70 i+ that exists on a long line. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The process of moving from this folded multiple-line representation Err bitreich.org 70 i+ to its single-line representation is called "unfolding". Unfolding Err bitreich.org 70 i+ is accomplished by removing the CRLF and the linear white-space Err bitreich.org 70 i+ character that immediately follows. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 9] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ When parsing a content line, folded lines MUST first be unfolded Err bitreich.org 70 i+ according to the unfolding procedure described above. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Note: It is possible for very simple implementations to generate Err bitreich.org 70 i+ improperly folded lines in the middle of a UTF-8 multi-octet Err bitreich.org 70 i+ sequence. For this reason, implementations need to unfold lines Err bitreich.org 70 i+ in such a way to properly restore the original sequence. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The content information associated with an iCalendar object is Err bitreich.org 70 i+ formatted using a syntax similar to that defined by [RFC2425]. That Err bitreich.org 70 i+ is, the content information consists of CRLF-separated content lines. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following notation defines the lines of content in an iCalendar Err bitreich.org 70 i+ object: Err bitreich.org 70 i+ Err bitreich.org 70 i+ contentline = name *(";" param ) ":" value CRLF Err bitreich.org 70 i+ ; This ABNF is just a general definition for an initial parsing Err bitreich.org 70 i+ ; of the content line into its property name, parameter list, Err bitreich.org 70 i+ ; and value string Err bitreich.org 70 i+ Err bitreich.org 70 i+ ; When parsing a content line, folded lines MUST first Err bitreich.org 70 i+ ; be unfolded according to the unfolding procedure Err bitreich.org 70 i+ ; described above.

Refer to the section describing each property for Err bitreich.org 70 i+ a definition of this format. Err bitreich.org 70 i+ Err bitreich.org 70 i+ All names of properties, property parameters, enumerated property Err bitreich.org 70 i+ values and property parameter values are case-insensitive. However, Err bitreich.org 70 i+ all other property values are case-sensitive, unless otherwise Err bitreich.org 70 i+ stated. Err bitreich.org 70 i+ Err bitreich.org 70 i+3.1.1. List and Field Separators Err bitreich.org 70 i+ Err bitreich.org 70 i+ Some properties and parameters allow a list of values. Values in a Err bitreich.org 70 i+ list of values MUST be separated by a COMMA character. There is no Err bitreich.org 70 i+ significance to the order of values in a list. For those parameter Err bitreich.org 70 i+ values (such as those that specify URI values) that are specified in Err bitreich.org 70 i+ quoted-strings, the individual quoted-strings are separated by a Err bitreich.org 70 i+ COMMA character. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Some property values are defined in terms of multiple parts. These Err bitreich.org 70 i+ structured property values MUST have their value parts separated by a Err bitreich.org 70 i+ SEMICOLON character. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Some properties allow a list of parameters. Each property parameter Err bitreich.org 70 i+ in a list of property parameters MUST be separated by a SEMICOLON Err bitreich.org 70 i+ character.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ For example, in the following properties, a SEMICOLON is used to Err bitreich.org 70 i+ separate property parameters from each other and a COMMA character is Err bitreich.org 70 i+ used to separate property values in a value list.

Multiple Values Err bitreich.org 70 i+ Err bitreich.org 70 i+ Some properties defined in the iCalendar object can have multiple Err bitreich.org 70 i+ values. The general rule for encoding multi-valued items is to Err bitreich.org 70 i+ simply create a new content line for each value, including the Err bitreich.org 70 i+ property name. However, it should be noted that some properties Err bitreich.org 70 i+ support encoding multiple values in a single property by separating Err bitreich.org 70 i+ the values with a COMMA character. Individual property definitions Err bitreich.org 70 i+ should be consulted for determining whether a specific property Err bitreich.org 70 i+ allows multiple values and in which of these two forms. Multi-valued Err bitreich.org 70 i+ properties MUST NOT be used to specify multiple language variants of Err bitreich.org 70 i+ the same value. Calendar applications SHOULD display all values. Err bitreich.org 70 i+ Err bitreich.org 70 i+3.1.3. Binary Content Err bitreich.org 70 i+ Err bitreich.org 70 i+ Binary content information in an iCalendar object SHOULD be Err bitreich.org 70 i+ referenced using a URI within a property value. That is, the binary Err bitreich.org 70 i+ content information SHOULD be placed in an external MIME entity that Err bitreich.org 70 i+ can be referenced by a URI from within the iCalendar object. In Err bitreich.org 70 i+ applications where this is not feasible, binary content information Err bitreich.org 70 i+ can be included within an iCalendar object, but only after first Err bitreich.org 70 i+ encoding it into text using the "BASE64" encoding method defined in Err bitreich.org 70 i+ [RFC4648].

Err bitreich.org 70 i+ Err bitreich.org 70 i+ Format Definition: This value type is defined by the following Err bitreich.org 70 i+ notation: Err bitreich.org 70 i+ Err bitreich.org 70 i+ date = date-value Err bitreich.org 70 i+ Err bitreich.org 70 i+ date-value = date-fullyear date-month date-mday Err bitreich.org 70 i+ date-fullyear = 4DIGIT Err bitreich.org 70 i+ date-month = 2DIGIT ;01-12 Err bitreich.org 70 i+ date-mday = 2DIGIT ;01-28, 01-29, 01-30, 01-31 Err bitreich.org 70 i+ ;based on month/year Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: If the property permits, multiple "date" values are Err bitreich.org 70 i+ specified as a COMMA-separated list of values. The format for the Err bitreich.org 70 i+ value type is based on the [ISO.8601.2004] complete Err bitreich.org 70 i+ representation, basic format for a calendar date.

There are no separator characters between the Err bitreich.org 70 i+ year, month, and day component text. Err bitreich.org 70 i+ Err bitreich.org 70 i+ No additional content value encoding (i.e., BACKSLASH character Err bitreich.org 70 i+ encoding, see Section 3.3.11) is defined for this value type.

Date-Time Err bitreich.org 70 i+ Err bitreich.org 70 i+ Value Name: DATE-TIME Err bitreich.org 70 i+ Err bitreich.org 70 i+ Purpose: This value type is used to identify values that specify a Err bitreich.org 70 i+ precise calendar date and time of day.

No additional Err bitreich.org 70 i+ content value encoding (i.e., BACKSLASH character encoding, see Err bitreich.org 70 i+ Section 3.3.11) is defined for this value type. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "DATE-TIME" value type is used to identify values that contain Err bitreich.org 70 i+ a precise calendar date and time of day. The format is based on Err bitreich.org 70 i+ the [ISO.8601.2004] complete representation, basic format for a Err bitreich.org 70 i+ calendar date and time of day. The text format is a concatenation Err bitreich.org 70 i+ of the "date", followed by the LATIN CAPITAL LETTER T character, Err bitreich.org 70 i+ the time designator, followed by the "time" format. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "DATE-TIME" value type expresses time values in three forms: Err bitreich.org 70 i+ Err bitreich.org 70 i+ The form of date and time with UTC offset MUST NOT be used. For Err bitreich.org 70 i+ example, the following is not valid for a DATE-TIME value: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 19980119T230000-0800 ;Invalid time format Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #1: DATE WITH LOCAL TIME Err bitreich.org 70 i+ Err bitreich.org 70 i+ The date with local time form is simply a DATE-TIME value that Err bitreich.org 70 i+ does not contain the UTC designator nor does it reference a time Err bitreich.org 70 i+ zone. For example, the following represents January 18, 1998, at Err bitreich.org 70 i+ 11 PM: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 19980118T230000 Err bitreich.org 70 i+ Err bitreich.org 70 i+ DATE-TIME values of this type are said to be "floating" and are Err bitreich.org 70 i+ not bound to any time zone in particular. They are used to Err bitreich.org 70 i+ represent the same hour, minute, and second value regardless of Err bitreich.org 70 i+ which time zone is currently being observed. For example, an Err bitreich.org 70 i+ event can be defined that indicates that an individual will be Err bitreich.org 70 i+ busy from 11:00 AM to 1:00 PM every day, no matter which time zone Err bitreich.org 70 i+ the person is in. In these cases, a local time can be specified. Err bitreich.org 70 i+ The recipient of an iCalendar object with a property value Err bitreich.org 70 i+ consisting of a local time, without any relative time zone Err bitreich.org 70 i+ information, SHOULD interpret the value as being fixed to whatever Err bitreich.org 70 i+ time zone the "ATTENDEE" is in at any given moment. This means Err bitreich.org 70 i+ that two "Attendees", in different time zones, receiving the same Err bitreich.org 70 i+ event definition as a floating time, may be participating in the Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 33] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ event at different actual times. Floating time SHOULD only be Err bitreich.org 70 i+ used where that is the reasonable behavior. Err bitreich.org 70 i+ Err bitreich.org 70 i+ In most cases, a fixed time is desired. To properly communicate a Err bitreich.org 70 i+ fixed time in a property value, either UTC time or local time with Err bitreich.org 70 i+ time zone reference MUST be specified. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The use of local time in a DATE-TIME value without the "TZID" Err bitreich.org 70 i+ property parameter is to be interpreted as floating time, Err bitreich.org 70 i+ regardless of the existence of "VTIMEZONE" calendar components in Err bitreich.org 70 i+ the iCalendar object. Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #2: DATE WITH UTC TIME Err bitreich.org 70 i+ Err bitreich.org 70 i+ The date with UTC time, or absolute time, is identified by a LATIN Err bitreich.org 70 i+ CAPITAL LETTER Z suffix character, the UTC designator, appended to Err bitreich.org 70 i+ the time value. For example, the following represents January 19, Err bitreich.org 70 i+ 1998, at 0700 UTC: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 19980119T070000Z Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "TZID" property parameter MUST NOT be applied to DATE-TIME Err bitreich.org 70 i+ properties whose time values are specified in UTC. Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #3: DATE WITH LOCAL TIME AND TIME ZONE REFERENCE Err bitreich.org 70 i+ Err bitreich.org 70 i+ The date and local time with reference to time zone information is Err bitreich.org 70 i+ identified by the use the "TZID" property parameter to reference Err bitreich.org 70 i+ the appropriate time zone definition. "TZID" is discussed in Err bitreich.org 70 i+ detail in Section 3.2.19. For example, the following represents Err bitreich.org 70 i+ 2:00 A.M. in New York on January 19, 1998: Err bitreich.org 70 i+ Err bitreich.org 70 i+ TZID=America/New_York:19980119T020000 Err bitreich.org 70 i+ Err bitreich.org 70 i+ If, based on the definition of the referenced time zone, the local Err bitreich.org 70 i+ time described occurs more than once (when changing from daylight Err bitreich.org 70 i+ to standard time), the DATE-TIME value refers to the first Err bitreich.org 70 i+ occurrence of the referenced time. Thus, TZID=America/ Err bitreich.org 70 i+ New_York:20071104T013000 indicates November 4, 2007 at 1:30 A.M. Err bitreich.org 70 i+ EDT (UTC-04:00). If the local time described does not occur (when Err bitreich.org 70 i+ changing from standard to daylight time), the DATE-TIME value is Err bitreich.org 70 i+ interpreted using the UTC offset before the gap in local times. Err bitreich.org 70 i+ Thus, TZID=America/New_York:20070311T023000 indicates March 11, Err bitreich.org 70 i+ 2007 at 3:30 A.M. EDT (UTC-04:00), one hour after 1:30 A.M. EST Err bitreich.org 70 i+ (UTC-05:00).

The format is Err bitreich.org 70 i+ based on the [ISO.8601.2004] complete representation basic format Err bitreich.org 70 i+ with designators for the duration of time. The format can Err bitreich.org 70 i+ represent nominal durations (weeks and days) and accurate Err bitreich.org 70 i+ durations (hours, minutes, and seconds). Note that unlike Err bitreich.org 70 i+ [ISO.8601.2004], this value type doesn't support the "Y" and "M" Err bitreich.org 70 i+ designators to specify durations in terms of years and months.

For example, Err bitreich.org 70 i+ within a DAILY rule, a value of "8" means every eight days. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The UNTIL rule part defines a DATE or DATE-TIME value that bounds Err bitreich.org 70 i+ the recurrence rule in an inclusive manner. If the value Err bitreich.org 70 i+ specified by UNTIL is synchronized with the specified recurrence, Err bitreich.org 70 i+ this DATE or DATE-TIME becomes the last instance of the Err bitreich.org 70 i+ recurrence.

Furthermore, if the Err bitreich.org 70 i+ "DTSTART" property is specified as a date with local time, then Err bitreich.org 70 i+ the UNTIL rule part MUST also be specified as a date with local Err bitreich.org 70 i+ time. If the "DTSTART" property is specified as a date with UTC Err bitreich.org 70 i+ time or a date with local time and time zone reference, then the Err bitreich.org 70 i+ UNTIL rule part MUST be specified as a date with UTC time.

If not present, and the COUNT rule part is also not Err bitreich.org 70 i+ present, the "RRULE" is considered to repeat forever. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The COUNT rule part defines the number of occurrences at which to Err bitreich.org 70 i+ range-bound the recurrence. The "DTSTART" property value always Err bitreich.org 70 i+ counts as the first occurrence. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYSECOND rule part specifies a COMMA-separated list of seconds Err bitreich.org 70 i+ within a minute. Valid values are 0 to 60. The BYMINUTE rule Err bitreich.org 70 i+ part specifies a COMMA-separated list of minutes within an hour. Err bitreich.org 70 i+ Valid values are 0 to 59. The BYHOUR rule part specifies a COMMA- Err bitreich.org 70 i+ separated list of hours of the day. Valid values are 0 to 23. Err bitreich.org 70 i+ The BYSECOND, BYMINUTE and BYHOUR rule parts MUST NOT be specified Err bitreich.org 70 i+ when the associated "DTSTART" property has a DATE value type.

The numeric value in a Err bitreich.org 70 i+ BYDAY rule part with the FREQ rule part set to YEARLY corresponds Err bitreich.org 70 i+ to an offset within the month when the BYMONTH rule part is Err bitreich.org 70 i+ present, and corresponds to an offset within the year when the Err bitreich.org 70 i+ BYWEEKNO or BYMONTH rule parts are present. If an integer Err bitreich.org 70 i+ modifier is not present, it means all days of this type within the Err bitreich.org 70 i+ specified frequency.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYMONTHDAY rule part specifies a COMMA-separated list of days Err bitreich.org 70 i+ of the month. Valid values are 1 to 31 or -31 to -1. For Err bitreich.org 70 i+ example, -10 represents the tenth to the last day of the month.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYYEARDAY rule part specifies a COMMA-separated list of days Err bitreich.org 70 i+ of the year. Valid values are 1 to 366 or -366 to -1. For Err bitreich.org 70 i+ example, -1 represents the last day of the year (December 31st) Err bitreich.org 70 i+ and -306 represents the 306th to the last day of the year (March Err bitreich.org 70 i+ 1st). The BYYEARDAY rule part MUST NOT be specified when the FREQ Err bitreich.org 70 i+ rule part is set to DAILY, WEEKLY, or MONTHLY. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYWEEKNO rule part specifies a COMMA-separated list of Err bitreich.org 70 i+ ordinals specifying weeks of the year. Valid values are 1 to 53 Err bitreich.org 70 i+ or -53 to -1. This corresponds to weeks according to week Err bitreich.org 70 i+ numbering as defined in [ISO.8601.2004]. A week is defined as a Err bitreich.org 70 i+ seven day period, starting on the day of the week defined to be Err bitreich.org 70 i+ the week start (see WKST). Week number one of the calendar year Err bitreich.org 70 i+ is the first week that contains at least four (4) days in that Err bitreich.org 70 i+ calendar year. This rule part MUST NOT be used when the FREQ rule Err bitreich.org 70 i+ part is set to anything other than YEARLY. For example, 3 Err bitreich.org 70 i+ represents the third week of the year. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Note: Assuming a Monday week start, week 53 can only occur when Err bitreich.org 70 i+ Thursday is January 1 or if it is a leap year and Wednesday is Err bitreich.org 70 i+ January 1. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYMONTH rule part specifies a COMMA-separated list of months Err bitreich.org 70 i+ of the year. Valid values are 1 to 12. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The WKST rule part specifies the day on which the workweek starts. Err bitreich.org 70 i+ Valid values are MO, TU, WE, TH, FR, SA, and SU.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The BYSETPOS rule part specifies a COMMA-separated list of values Err bitreich.org 70 i+ that corresponds to the nth occurrence within the set of Err bitreich.org 70 i+ recurrence instances specified by the rule. BYSETPOS operates on Err bitreich.org 70 i+ a set of recurrence instances in one interval of the recurrence Err bitreich.org 70 i+ rule. For example, in a WEEKLY rule, the interval would be one Err bitreich.org 70 i+ week A set of recurrence instances starts at the beginning of the Err bitreich.org 70 i+ interval defined by the FREQ rule part. Valid values are 1 to 366 Err bitreich.org 70 i+ or -366 to -1. It MUST only be used in conjunction with another Err bitreich.org 70 i+ BYxxx rule part. For example "the last work day of the month" Err bitreich.org 70 i+ could be represented as: Err bitreich.org 70 i+ Err bitreich.org 70 i+ FREQ=MONTHLY;BYDAY=MO,TU,WE,TH,FR;BYSETPOS=-1 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Each BYSETPOS value can include a positive (+n) or negative (-n) Err bitreich.org 70 i+ integer. If present, this indicates the nth occurrence of the Err bitreich.org 70 i+ specific occurrence within the set of occurrences specified by the Err bitreich.org 70 i+ rule. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Recurrence rules may generate recurrence instances with an invalid Err bitreich.org 70 i+ date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM Err bitreich.org 70 i+ on a day where the local time is moved forward by an hour at 1:00 Err bitreich.org 70 i+ AM). Such recurrence instances MUST be ignored and MUST NOT be Err bitreich.org 70 i+ counted as part of the recurrence set. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Information, not contained in the rule, necessary to determine the Err bitreich.org 70 i+ various recurrence instance start time and dates are derived from Err bitreich.org 70 i+ the Start Time ("DTSTART") component attribute. For example, Err bitreich.org 70 i+ "FREQ=YEARLY;BYMONTH=1" doesn't specify a specific day within the Err bitreich.org 70 i+ month or a time. This information would be the same as what is Err bitreich.org 70 i+ specified for "DTSTART". Err bitreich.org 70 i+ Err bitreich.org 70 i+ BYxxx rule parts modify the recurrence in some manner. BYxxx rule Err bitreich.org 70 i+ parts for a period of time that is the same or greater than the Err bitreich.org 70 i+ frequency generally reduce or limit the number of occurrences of Err bitreich.org 70 i+ the recurrence generated. For example, "FREQ=DAILY;BYMONTH=1" Err bitreich.org 70 i+ reduces the number of recurrence instances from all days (if Err bitreich.org 70 i+ BYMONTH rule part is not present) to all days in January.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ time-utc = "Z" Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: If the property permits, multiple "time" values are Err bitreich.org 70 i+ specified by a COMMA-separated list of values. No additional Err bitreich.org 70 i+ content value encoding (i.e., BACKSLASH character encoding, see Err bitreich.org 70 i+ Section 3.3.11) is defined for this value type. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "TIME" value type is used to identify values that contain a Err bitreich.org 70 i+ time of day. The format is based on the [ISO.8601.2004] complete Err bitreich.org 70 i+ representation, basic format for a time of day. The text format Err bitreich.org 70 i+ consists of a two-digit, 24-hour of the day (i.e., values 00-23), Err bitreich.org 70 i+ two-digit minute in the hour (i.e., values 00-59), and two-digit Err bitreich.org 70 i+ seconds in the minute (i.e., values 00-60). The seconds value of Err bitreich.org 70 i+ 60 MUST only be used to account for positive "leap" seconds. Err bitreich.org 70 i+ Fractions of a second are not supported by this format. Err bitreich.org 70 i+ Err bitreich.org 70 i+ In parallel to the "DATE-TIME" definition above, the "TIME" value Err bitreich.org 70 i+ type expresses time values in three forms: Err bitreich.org 70 i+ Err bitreich.org 70 i+ The form of time with UTC offset MUST NOT be used. For example, Err bitreich.org 70 i+ the following is not valid for a time value: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 230000-0800 ;Invalid time format Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #1 LOCAL TIME Err bitreich.org 70 i+ Err bitreich.org 70 i+ The local time form is simply a time value that does not contain Err bitreich.org 70 i+ the UTC designator nor does it reference a time zone. For Err bitreich.org 70 i+ example, 11:00 PM: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 230000 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 47] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Time values of this type are said to be "floating" and are not Err bitreich.org 70 i+ bound to any time zone in particular. They are used to represent Err bitreich.org 70 i+ the same hour, minute, and second value regardless of which time Err bitreich.org 70 i+ zone is currently being observed. For example, an event can be Err bitreich.org 70 i+ defined that indicates that an individual will be busy from 11:00 Err bitreich.org 70 i+ AM to 1:00 PM every day, no matter which time zone the person is Err bitreich.org 70 i+ in. In these cases, a local time can be specified. The recipient Err bitreich.org 70 i+ of an iCalendar object with a property value consisting of a local Err bitreich.org 70 i+ time, without any relative time zone information, SHOULD interpret Err bitreich.org 70 i+ the value as being fixed to whatever time zone the "ATTENDEE" is Err bitreich.org 70 i+ in at any given moment. This means that two "Attendees", may Err bitreich.org 70 i+ participate in the same event at different UTC times; floating Err bitreich.org 70 i+ time SHOULD only be used where that is reasonable behavior. Err bitreich.org 70 i+ Err bitreich.org 70 i+ In most cases, a fixed time is desired. To properly communicate a Err bitreich.org 70 i+ fixed time in a property value, either UTC time or local time with Err bitreich.org 70 i+ time zone reference MUST be specified. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The use of local time in a TIME value without the "TZID" property Err bitreich.org 70 i+ parameter is to be interpreted as floating time, regardless of the Err bitreich.org 70 i+ existence of "VTIMEZONE" calendar components in the iCalendar Err bitreich.org 70 i+ object. Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #2: UTC TIME Err bitreich.org 70 i+ Err bitreich.org 70 i+ UTC time, or absolute time, is identified by a LATIN CAPITAL Err bitreich.org 70 i+ LETTER Z suffix character, the UTC designator, appended to the Err bitreich.org 70 i+ time value. For example, the following represents 07:00 AM UTC: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 070000Z Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "TZID" property parameter MUST NOT be applied to TIME Err bitreich.org 70 i+ properties whose time values are specified in UTC. Err bitreich.org 70 i+ Err bitreich.org 70 i+ FORM #3: LOCAL TIME AND TIME ZONE REFERENCE Err bitreich.org 70 i+ Err bitreich.org 70 i+ The local time with reference to time zone information form is Err bitreich.org 70 i+ identified by the use the "TZID" property parameter to reference Err bitreich.org 70 i+ the appropriate time zone definition. "TZID" is discussed in Err bitreich.org 70 i+ detail in Section 3.2.19. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Example: The following represents 8:30 AM in New York in winter, Err bitreich.org 70 i+ five hours behind UTC, in each of the three formats: Err bitreich.org 70 i+ Err bitreich.org 70 i+ 083000 Err bitreich.org 70 i+ 133000Z Err bitreich.org 70 i+ TZID=America/New_York:083000 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 48] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+3.3.13.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ When a property parameter value is a URI value type, the URI MUST Err bitreich.org 70 i+ be specified as a quoted-string value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ No additional content value encoding (i.e., BACKSLASH character Err bitreich.org 70 i+ encoding, see Section 3.3.11) is defined for this value type.

Typically, this information Err bitreich.org 70 i+ will consist of an iCalendar stream with a single iCalendar object. Err bitreich.org 70 i+ However, multiple iCalendar objects can be sequentially grouped Err bitreich.org 70 i+ together in an iCalendar stream. The first line and last line of the Err bitreich.org 70 i+ iCalendar object MUST contain a pair of iCalendar object delimiter Err bitreich.org 70 i+ strings. The syntax for an iCalendar stream is as follows: Err bitreich.org 70 i+ Err bitreich.org 70 i+ icalstream = 1*icalobject Err bitreich.org 70 i+ Err bitreich.org 70 i+ icalobject = "BEGIN" ":" "VCALENDAR" CRLF Err bitreich.org 70 i+ icalbody Err bitreich.org 70 i+ "END" ":" "VCALENDAR" CRLF Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following is a simple example of an iCalendar object: Err bitreich.org 70 i+ Err bitreich.org 70 i+ BEGIN:VCALENDAR Err bitreich.org 70 i+ VERSION:2.0 Err bitreich.org 70 i+ PRODID:-//hacksw/handcal//NONSGML v1.0//EN Err bitreich.org 70 i+ BEGIN:VEVENT Err bitreich.org 70 i+ UID:19970610T172345Z-AF23B2@example.com Err bitreich.org 70 i+ DTSTAMP:19970610T172345Z Err bitreich.org 70 i+ DTSTART:19970714T170000Z Err bitreich.org 70 i+ DTEND:19970715T040000Z Err bitreich.org 70 i+ SUMMARY:Bastille Day Party Err bitreich.org 70 i+ END:VEVENT Err bitreich.org 70 i+ END:VCALENDAR Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 50] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+3.5. Property Err bitreich.org 70 i+ Err bitreich.org 70 i+ A property is the definition of an individual attribute describing a Err bitreich.org 70 i+ calendar object or a calendar component. A property takes the form Err bitreich.org 70 i+ defined by the "contentline" notation defined in Section 3.1. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following is an example of a property: Err bitreich.org 70 i+ Err bitreich.org 70 i+ DTSTART:19960415T133000Z Err bitreich.org 70 i+ Err bitreich.org 70 i+ This memo imposes no ordering of properties within an iCalendar Err bitreich.org 70 i+ object. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property names, parameter names, and enumerated parameter values are Err bitreich.org 70 i+ case-insensitive. For example, the property name "DUE" is the same Err bitreich.org 70 i+ as "due" and "Due", DTSTART;TZID=America/New_York:19980714T120000 is Err bitreich.org 70 i+ the same as DtStart;TzID=America/New_York:19980714T120000. Err bitreich.org 70 i+ Err bitreich.org 70 i+3.6. Calendar Components Err bitreich.org 70 i+ Err bitreich.org 70 i+ The body of the iCalendar object consists of a sequence of calendar Err bitreich.org 70 i+ properties and one or more calendar components. The calendar Err bitreich.org 70 i+ properties are attributes that apply to the calendar object as a Err bitreich.org 70 i+ whole. The calendar components are collections of properties that Err bitreich.org 70 i+ express a particular calendar semantic.

For example, it can be an activity; such as a one-hour Err bitreich.org 70 i+ long, department meeting from 8:00 AM to 9:00 AM, tomorrow. Err bitreich.org 70 i+ Generally, an event will take up time on an individual calendar. Err bitreich.org 70 i+ Hence, the event will appear as an opaque interval in a search for Err bitreich.org 70 i+ busy time.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "VEVENT" is also the calendar component used to specify an Err bitreich.org 70 i+ anniversary or daily reminder within a calendar. These events Err bitreich.org 70 i+ have a DATE value type for the "DTSTART" property instead of the Err bitreich.org 70 i+ default value type of DATE-TIME. If such a "VEVENT" has a "DTEND" Err bitreich.org 70 i+ property, it MUST be specified as a DATE value also. The Err bitreich.org 70 i+ anniversary type of "VEVENT" can span more than one date (i.e., Err bitreich.org 70 i+ "DTEND" property value is set to a calendar date after the Err bitreich.org 70 i+ "DTSTART" property value). If such a "VEVENT" has a "DURATION" Err bitreich.org 70 i+ property, it MUST be specified as a "dur-day" or "dur-week" value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "DTSTART" property for a "VEVENT" specifies the inclusive Err bitreich.org 70 i+ start of the event. For recurring events, it also specifies the Err bitreich.org 70 i+ very first instance in the recurrence set. The "DTEND" property Err bitreich.org 70 i+ for a "VEVENT" calendar component specifies the non-inclusive end Err bitreich.org 70 i+ of the event. For cases where a "VEVENT" calendar component Err bitreich.org 70 i+ specifies a "DTSTART" property with a DATE value type but no Err bitreich.org 70 i+ "DTEND" nor "DURATION" property, the event's duration is taken to Err bitreich.org 70 i+ be one day. For cases where a "VEVENT" calendar component Err bitreich.org 70 i+ specifies a "DTSTART" property with a DATE-TIME value type but no Err bitreich.org 70 i+ "DTEND" property, the event ends on the same calendar date and Err bitreich.org 70 i+ time of day specified by the "DTSTART" property. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "VEVENT" calendar component cannot be nested within another Err bitreich.org 70 i+ calendar component.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "VTIMEZONE" calendar component MUST include the "TZID" Err bitreich.org 70 i+ property and at least one definition of a "STANDARD" or "DAYLIGHT" Err bitreich.org 70 i+ sub-component. The "STANDARD" or "DAYLIGHT" sub-component MUST Err bitreich.org 70 i+ include the "DTSTART", "TZOFFSETFROM", and "TZOFFSETTO" Err bitreich.org 70 i+ properties. Err bitreich.org 70 i+ Err bitreich.org 70 i+ An individual "VTIMEZONE" calendar component MUST be specified for Err bitreich.org 70 i+ each unique "TZID" parameter value specified in the iCalendar Err bitreich.org 70 i+ object. In addition, a "VTIMEZONE" calendar component, referred Err bitreich.org 70 i+ to by a recurring calendar component, MUST provide valid time zone Err bitreich.org 70 i+ information for all recurrence instances. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Each "VTIMEZONE" calendar component consists of a collection of Err bitreich.org 70 i+ one or more sub-components that describe the rule for a particular Err bitreich.org 70 i+ observance (either a Standard Time or a Daylight Saving Time Err bitreich.org 70 i+ observance). The "STANDARD" sub-component consists of a Err bitreich.org 70 i+ collection of properties that describe Standard Time. The Err bitreich.org 70 i+ "DAYLIGHT" sub-component consists of a collection of properties Err bitreich.org 70 i+ that describe Daylight Saving Time. In general, this collection Err bitreich.org 70 i+ of properties consists of: Err bitreich.org 70 i+ Err bitreich.org 70 i+ * the first onset DATE-TIME for the observance; Err bitreich.org 70 i+ Err bitreich.org 70 i+ * the last onset DATE-TIME for the observance, if a last onset is Err bitreich.org 70 i+ known; Err bitreich.org 70 i+ Err bitreich.org 70 i+ * the offset to be applied for the observance; Err bitreich.org 70 i+ Err bitreich.org 70 i+ * a rule that describes the day and time when the observance Err bitreich.org 70 i+ takes effect; Err bitreich.org 70 i+ Err bitreich.org 70 i+ * an optional name for the observance.

Err bitreich.org 70 i+ The collection of these sub-components is used to describe the Err bitreich.org 70 i+ time zone for a given period of time. The offset to apply at any Err bitreich.org 70 i+ given time is found by locating the observance that has the last Err bitreich.org 70 i+ onset date and time before the time in question, and using the Err bitreich.org 70 i+ offset value from that observance. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The top-level properties in a "VTIMEZONE" calendar component are: Err bitreich.org 70 i+ Err bitreich.org 70 i+ The mandatory "TZID" property is a text value that uniquely Err bitreich.org 70 i+ identifies the "VTIMEZONE" calendar component within the scope of Err bitreich.org 70 i+ an iCalendar object. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The optional "LAST-MODIFIED" property is a UTC value that Err bitreich.org 70 i+ specifies the date and time that this time zone definition was Err bitreich.org 70 i+ last updated. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The optional "TZURL" property is a url value that points to a Err bitreich.org 70 i+ published "VTIMEZONE" definition. "TZURL" SHOULD refer to a Err bitreich.org 70 i+ resource that is accessible by anyone who might need to interpret Err bitreich.org 70 i+ the object.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The collection of properties that are used to define the Err bitreich.org 70 i+ "STANDARD" and "DAYLIGHT" sub-components include: Err bitreich.org 70 i+ Err bitreich.org 70 i+ The mandatory "DTSTART" property gives the effective onset date Err bitreich.org 70 i+ and local time for the time zone sub-component definition. Err bitreich.org 70 i+ "DTSTART" in this usage MUST be specified as a date with a local Err bitreich.org 70 i+ time value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The mandatory "TZOFFSETFROM" property gives the UTC offset that is Err bitreich.org 70 i+ in use when the onset of this time zone observance begins. Err bitreich.org 70 i+ "TZOFFSETFROM" is combined with "DTSTART" to define the effective Err bitreich.org 70 i+ onset for the time zone sub-component definition.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "RDATE" property can also be used to define the onset of the Err bitreich.org 70 i+ observance by giving the individual onset date and times. "RDATE" Err bitreich.org 70 i+ in this usage MUST be specified as a date with local time value, Err bitreich.org 70 i+ relative to the UTC offset specified in the "TZOFFSETFROM" Err bitreich.org 70 i+ property.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "VALARM" calendar component MUST include the "ACTION" and Err bitreich.org 70 i+ "TRIGGER" properties.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ When the action is "DISPLAY", the alarm MUST also include a Err bitreich.org 70 i+ "DESCRIPTION" property, which contains the text to be displayed Err bitreich.org 70 i+ when the alarm is triggered. Err bitreich.org 70 i+ Err bitreich.org 70 i+ When the action is "EMAIL", the alarm MUST include a "DESCRIPTION" Err bitreich.org 70 i+ property, which contains the text to be used as the message body, Err bitreich.org 70 i+ a "SUMMARY" property, which contains the text to be used as the Err bitreich.org 70 i+ message subject, and one or more "ATTENDEE" properties, which Err bitreich.org 70 i+ contain the email address of attendees to receive the message. It Err bitreich.org 70 i+ can also include one or more "ATTACH" properties, which are Err bitreich.org 70 i+ intended to be sent as message attachments. When the alarm is Err bitreich.org 70 i+ triggered, the email message is sent. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "VALARM" calendar component MUST only appear within either a Err bitreich.org 70 i+ "VEVENT" or "VTODO" calendar component.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "TRIGGER" property specifies when the alarm will be triggered. Err bitreich.org 70 i+ The "TRIGGER" property specifies a duration prior to the start of Err bitreich.org 70 i+ an event or a to-do. The "TRIGGER" edge may be explicitly set to Err bitreich.org 70 i+ be relative to the "START" or "END" of the event or to-do with the Err bitreich.org 70 i+ "RELATED" parameter of the "TRIGGER" property. The "TRIGGER" Err bitreich.org 70 i+ property value type can alternatively be set to an absolute Err bitreich.org 70 i+ calendar date with UTC time. Err bitreich.org 70 i+ Err bitreich.org 70 i+ In an alarm set to trigger on the "START" of an event or to-do, Err bitreich.org 70 i+ the "DTSTART" property MUST be present in the associated event or Err bitreich.org 70 i+ to-do. In an alarm in a "VEVENT" calendar component set to Err bitreich.org 70 i+ trigger on the "END" of the event, either the "DTEND" property Err bitreich.org 70 i+ MUST be present, or the "DTSTART" and "DURATION" properties MUST Err bitreich.org 70 i+ both be present. In an alarm in a "VTODO" calendar component set Err bitreich.org 70 i+ to trigger on the "END" of the to-do, either the "DUE" property Err bitreich.org 70 i+ MUST be present, or the "DTSTART" and "DURATION" properties MUST Err bitreich.org 70 i+ both be present. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The alarm can be defined such that it triggers repeatedly. A Err bitreich.org 70 i+ definition of an alarm with a repeating trigger MUST include both Err bitreich.org 70 i+ the "DURATION" and "REPEAT" properties. The "DURATION" property Err bitreich.org 70 i+ specifies the delay period, after which the alarm will repeat. Err bitreich.org 70 i+ The "REPEAT" property specifies the number of additional Err bitreich.org 70 i+ repetitions that the alarm will be triggered. This repetition Err bitreich.org 70 i+ count is in addition to the initial triggering of the alarm. Both Err bitreich.org 70 i+ of these properties MUST be present in order to specify a Err bitreich.org 70 i+ repeating alarm. If one of these two properties is absent, then Err bitreich.org 70 i+ the alarm will not repeat beyond the initial trigger. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "ACTION" property is used within the "VALARM" calendar Err bitreich.org 70 i+ component to specify the type of action invoked when the alarm is Err bitreich.org 70 i+ triggered. The "VALARM" properties provide enough information for Err bitreich.org 70 i+ a specific action to be invoked. It is typically the Err bitreich.org 70 i+ responsibility of a "Calendar User Agent" (CUA) to deliver the Err bitreich.org 70 i+ alarm in the specified fashion. An "ACTION" property value of Err bitreich.org 70 i+ AUDIO specifies an alarm that causes a sound to be played to alert Err bitreich.org 70 i+ the user; DISPLAY specifies an alarm that causes a text message to Err bitreich.org 70 i+ be displayed to the user; and EMAIL specifies an alarm that causes Err bitreich.org 70 i+ an electronic email message to be delivered to one or more email Err bitreich.org 70 i+ addresses. Err bitreich.org 70 i+ Err bitreich.org 70 i+ In an AUDIO alarm, if the optional "ATTACH" property is included, Err bitreich.org 70 i+ it MUST specify an audio sound resource. The intention is that Err bitreich.org 70 i+ the sound will be played as the alarm effect.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ In a DISPLAY alarm, the intended alarm effect is for the text Err bitreich.org 70 i+ value of the "DESCRIPTION" property to be displayed to the user.

It Err bitreich.org 70 i+ provides a method of capturing the scope of the access the Err bitreich.org 70 i+ calendar owner intends for information within an individual Err bitreich.org 70 i+ calendar entry. The access classification of an individual Err bitreich.org 70 i+ iCalendar component is useful when measured along with the other Err bitreich.org 70 i+ security components of a calendar system (e.g., calendar user Err bitreich.org 70 i+ authentication, authorization, access rights, access role, etc.). Err bitreich.org 70 i+ Hence, the semantics of the individual access classifications Err bitreich.org 70 i+ cannot be completely defined by this memo alone.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: This property is specified within the "VEVENT", Err bitreich.org 70 i+ "VTODO", and "VJOURNAL" calendar components to specify the Err bitreich.org 70 i+ organizer of a group-scheduled calendar entity. The property is Err bitreich.org 70 i+ specified within the "VFREEBUSY" calendar component to specify the Err bitreich.org 70 i+ calendar user requesting the free or busy time.

Recurrence ID Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Name: RECURRENCE-ID Err bitreich.org 70 i+ Err bitreich.org 70 i+ Purpose: This property is used in conjunction with the "UID" and Err bitreich.org 70 i+ "SEQUENCE" properties to identify a specific instance of a Err bitreich.org 70 i+ recurring "VEVENT", "VTODO", or "VJOURNAL" calendar component. Err bitreich.org 70 i+ The property value is the original value of the "DTSTART" property Err bitreich.org 70 i+ of the recurrence instance. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 112] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Value Type: The default value type is DATE-TIME. The value type can Err bitreich.org 70 i+ be set to a DATE value type. This property MUST have the same Err bitreich.org 70 i+ value type as the "DTSTART" property contained within the Err bitreich.org 70 i+ recurring component. Furthermore, this property MUST be specified Err bitreich.org 70 i+ as a date with local time if and only if the "DTSTART" property Err bitreich.org 70 i+ contained within the recurring component is specified as a date Err bitreich.org 70 i+ with local time. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Parameters: IANA, non-standard, value data type, time zone Err bitreich.org 70 i+ identifier, and recurrence identifier range parameters can be Err bitreich.org 70 i+ specified on this property. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Conformance: This property can be specified in an iCalendar object Err bitreich.org 70 i+ containing a recurring calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: The full range of calendar components specified by a Err bitreich.org 70 i+ recurrence set is referenced by referring to just the "UID" Err bitreich.org 70 i+ property value corresponding to the calendar component. The Err bitreich.org 70 i+ "RECURRENCE-ID" property allows the reference to an individual Err bitreich.org 70 i+ instance within the recurrence set. Err bitreich.org 70 i+ Err bitreich.org 70 i+ If the value of the "DTSTART" property is a DATE type value, then Err bitreich.org 70 i+ the value MUST be the calendar date for the recurrence instance. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The DATE-TIME value is set to the time when the original Err bitreich.org 70 i+ recurrence instance would occur; meaning that if the intent is to Err bitreich.org 70 i+ change a Friday meeting to Thursday, the DATE-TIME is still set to Err bitreich.org 70 i+ the original Friday meeting. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "RECURRENCE-ID" property is used in conjunction with the "UID" Err bitreich.org 70 i+ and "SEQUENCE" properties to identify a particular instance of a Err bitreich.org 70 i+ recurring event, to-do, or journal. For a given pair of "UID" and Err bitreich.org 70 i+ "SEQUENCE" property values, the "RECURRENCE-ID" value for a Err bitreich.org 70 i+ recurrence instance is fixed. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "RANGE" parameter is used to specify the effective range of Err bitreich.org 70 i+ recurrence instances from the instance specified by the Err bitreich.org 70 i+ "RECURRENCE-ID" property value. The value for the range parameter Err bitreich.org 70 i+ can only be "THISANDFUTURE" to indicate a range defined by the Err bitreich.org 70 i+ given recurrence instance and all subsequent instances. Err bitreich.org 70 i+ Subsequent instances are determined by their "RECURRENCE-ID" value Err bitreich.org 70 i+ and not their current scheduled start time. Subsequent instances Err bitreich.org 70 i+ defined in separate components are not impacted by the given Err bitreich.org 70 i+ recurrence instance. When the given recurrence instance is Err bitreich.org 70 i+ rescheduled, all subsequent instances are also rescheduled by the Err bitreich.org 70 i+ same time difference. For instance, if the given recurrence Err bitreich.org 70 i+ instance is rescheduled to start 2 hours later, then all Err bitreich.org 70 i+ subsequent instances are also rescheduled 2 hours later.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ Note: The "RANGE" parameter may not be appropriate to Err bitreich.org 70 i+ reschedule specific subsequent instances of complex recurring Err bitreich.org 70 i+ calendar component. Assuming an unbounded recurring calendar Err bitreich.org 70 i+ component scheduled to occur on Mondays and Wednesdays, the Err bitreich.org 70 i+ "RANGE" parameter could not be used to reschedule only the Err bitreich.org 70 i+ future Monday instances to occur on Tuesday instead. In such Err bitreich.org 70 i+ cases, the calendar application could simply truncate the Err bitreich.org 70 i+ unbounded recurring calendar component (i.e., with the "COUNT" Err bitreich.org 70 i+ or "UNTIL" rule parts), and create two new unbounded recurring Err bitreich.org 70 i+ calendar components for the future instances.

Related To Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Name: RELATED-TO Err bitreich.org 70 i+ Err bitreich.org 70 i+ Purpose: This property is used to represent a relationship or Err bitreich.org 70 i+ reference between one calendar component and another. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Value Type: TEXT Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Parameters: IANA, non-standard, and relationship type Err bitreich.org 70 i+ property parameters can be specified on this property. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Conformance: This property can be specified in the "VEVENT", Err bitreich.org 70 i+ "VTODO", and "VJOURNAL" calendar components. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: The property value consists of the persistent, globally Err bitreich.org 70 i+ unique identifier of another calendar component. This value would Err bitreich.org 70 i+ be represented in a calendar component by the "UID" property. Err bitreich.org 70 i+ Err bitreich.org 70 i+ By default, the property value points to another calendar Err bitreich.org 70 i+ component that has a PARENT relationship to the referencing Err bitreich.org 70 i+ object. The "RELTYPE" property parameter is used to either Err bitreich.org 70 i+ explicitly state the default PARENT relationship type to the Err bitreich.org 70 i+ referenced calendar component or to override the default PARENT Err bitreich.org 70 i+ relationship type and specify either a CHILD or SIBLING Err bitreich.org 70 i+ relationship. The PARENT relationship indicates that the calendar Err bitreich.org 70 i+ component is a subordinate of the referenced calendar component. Err bitreich.org 70 i+ The CHILD relationship indicates that the calendar component is a Err bitreich.org 70 i+ superior of the referenced calendar component. The SIBLING Err bitreich.org 70 i+ relationship indicates that the calendar component is a peer of Err bitreich.org 70 i+ the referenced calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Changes to a calendar component referenced by this property can Err bitreich.org 70 i+ have an implicit impact on the related calendar component. For Err bitreich.org 70 i+ example, if a group event changes its start or end date or time, Err bitreich.org 70 i+ then the related, dependent events will need to have their start Err bitreich.org 70 i+ and end dates changed in a corresponding way. Similarly, if a Err bitreich.org 70 i+ PARENT calendar component is cancelled or deleted, then there is Err bitreich.org 70 i+ an implied impact to the related CHILD calendar components. This Err bitreich.org 70 i+ property is intended only to provide information on the Err bitreich.org 70 i+ relationship of calendar components. It is up to the target Err bitreich.org 70 i+ calendar system to maintain any property implications of this Err bitreich.org 70 i+ relationship.

Unique Identifier Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Name: UID Err bitreich.org 70 i+ Err bitreich.org 70 i+ Purpose: This property defines the persistent, globally unique Err bitreich.org 70 i+ identifier for the calendar component.

Err bitreich.org 70 i+ The generator of the identifier MUST guarantee that the identifier Err bitreich.org 70 i+ is unique. There are several algorithms that can be used to Err bitreich.org 70 i+ accomplish this. A good method to assure uniqueness is to put the Err bitreich.org 70 i+ domain name or a domain literal IP address of the host on which Err bitreich.org 70 i+ the identifier was created on the right-hand side of an "@", and Err bitreich.org 70 i+ on the left-hand side, put a combination of the current calendar Err bitreich.org 70 i+ date and time of day (i.e., formatted in as a DATE-TIME value) Err bitreich.org 70 i+ along with some other currently unique (perhaps sequential) Err bitreich.org 70 i+ identifier available on the system (for example, a process id Err bitreich.org 70 i+ number). Using a DATE-TIME value on the left-hand side and a Err bitreich.org 70 i+ domain name or domain literal on the right-hand side makes it Err bitreich.org 70 i+ possible to guarantee uniqueness since no two hosts should be Err bitreich.org 70 i+ using the same domain name or IP address at the same time. Though Err bitreich.org 70 i+ other algorithms will work, it is RECOMMENDED that the right-hand Err bitreich.org 70 i+ side contain some domain identifier (either of the host itself or Err bitreich.org 70 i+ otherwise) such that the generator of the message identifier can Err bitreich.org 70 i+ guarantee the uniqueness of the left-hand side within the scope of Err bitreich.org 70 i+ that domain.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: The exception dates, if specified, are used in Err bitreich.org 70 i+ computing the recurrence set.

The "DTSTART" Err bitreich.org 70 i+ property value SHOULD match the pattern of the recurrence rule, if Err bitreich.org 70 i+ specified. The recurrence set generated with a "DTSTART" property Err bitreich.org 70 i+ value that doesn't match the pattern of the rule is undefined. Err bitreich.org 70 i+ The final recurrence set is generated by gathering all of the Err bitreich.org 70 i+ start DATE-TIME values generated by any of the specified "RRULE" Err bitreich.org 70 i+ and "RDATE" properties, and then excluding any start DATE-TIME Err bitreich.org 70 i+ values specified by "EXDATE" properties. This implies that start Err bitreich.org 70 i+ DATE-TIME values specified by "EXDATE" properties take precedence Err bitreich.org 70 i+ over those specified by inclusion properties (i.e., "RDATE" and Err bitreich.org 70 i+ "RRULE"). When duplicate instances are generated by the "RRULE" Err bitreich.org 70 i+ and "RDATE" properties, only one recurrence is considered. Err bitreich.org 70 i+ Duplicate instances are ignored. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "EXDATE" property can be used to exclude the value specified Err bitreich.org 70 i+ in "DTSTART". However, in such cases, the original "DTSTART" date Err bitreich.org 70 i+ MUST still be maintained by the calendaring and scheduling system Err bitreich.org 70 i+ because the original "DTSTART" value has inherent usage Err bitreich.org 70 i+ dependencies by other properties such as the "RECURRENCE-ID".

Err bitreich.org 70 i+ The recurrence set generated with multiple "RRULE" properties is Err bitreich.org 70 i+ undefined. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: The recurrence rule, if specified, is used in computing Err bitreich.org 70 i+ the recurrence set. The recurrence set is the complete set of Err bitreich.org 70 i+ recurrence instances for a calendar component. The recurrence set Err bitreich.org 70 i+ is generated by considering the initial "DTSTART" property along Err bitreich.org 70 i+ with the "RRULE", "RDATE", and "EXDATE" properties contained Err bitreich.org 70 i+ within the recurring component.

The "DTSTART" property Err bitreich.org 70 i+ value SHOULD be synchronized with the recurrence rule, if Err bitreich.org 70 i+ specified. The recurrence set generated with a "DTSTART" property Err bitreich.org 70 i+ value not synchronized with the recurrence rule is undefined. The Err bitreich.org 70 i+ final recurrence set is generated by gathering all of the start Err bitreich.org 70 i+ DATE-TIME values generated by any of the specified "RRULE" and Err bitreich.org 70 i+ "RDATE" properties, and then excluding any start DATE-TIME values Err bitreich.org 70 i+ specified by "EXDATE" properties.

Err bitreich.org 70 i+ Duplicate instances are ignored. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "DTSTART" property specified within the iCalendar object Err bitreich.org 70 i+ defines the first instance of the recurrence. In most cases, a Err bitreich.org 70 i+ "DTSTART" property of DATE-TIME value type used with a recurrence Err bitreich.org 70 i+ rule, should be specified as a date with local time and time zone Err bitreich.org 70 i+ reference to make sure all the recurrence instances start at the Err bitreich.org 70 i+ same local time regardless of time zone changes. Err bitreich.org 70 i+ Err bitreich.org 70 i+ If the duration of the recurring component is specified with the Err bitreich.org 70 i+ "DTEND" or "DUE" property, then the same exact duration will apply Err bitreich.org 70 i+ to all the members of the generated recurrence set. Else, if the Err bitreich.org 70 i+ duration of the recurring component is specified with the Err bitreich.org 70 i+ "DURATION" property, then the same nominal duration will apply to Err bitreich.org 70 i+ all the members of the generated recurrence set and the exact Err bitreich.org 70 i+ duration of each recurrence instance will depend on its specific Err bitreich.org 70 i+ start time. For example, recurrence instances of a nominal Err bitreich.org 70 i+ duration of one day will have an exact duration of more or less Err bitreich.org 70 i+ than 24 hours on a day where a time zone shift occurs.

Trigger Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Name: TRIGGER Err bitreich.org 70 i+ Err bitreich.org 70 i+ Purpose: This property specifies when an alarm will trigger. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Value Type: The default value type is DURATION. The value type can Err bitreich.org 70 i+ be set to a DATE-TIME value type, in which case the value MUST Err bitreich.org 70 i+ specify a UTC-formatted DATE-TIME value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 133] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Property Parameters: IANA, non-standard, value data type, time zone Err bitreich.org 70 i+ identifier, or trigger relationship property parameters can be Err bitreich.org 70 i+ specified on this property. The trigger relationship property Err bitreich.org 70 i+ parameter MUST only be specified when the value type is Err bitreich.org 70 i+ "DURATION". Err bitreich.org 70 i+ Err bitreich.org 70 i+ Conformance: This property MUST be specified in the "VALARM" Err bitreich.org 70 i+ calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: This property defines when an alarm will trigger. The Err bitreich.org 70 i+ default value type is DURATION, specifying a relative time for the Err bitreich.org 70 i+ trigger of the alarm. The default duration is relative to the Err bitreich.org 70 i+ start of an event or to-do with which the alarm is associated. Err bitreich.org 70 i+ The duration can be explicitly set to trigger from either the end Err bitreich.org 70 i+ or the start of the associated event or to-do with the "RELATED" Err bitreich.org 70 i+ parameter. A value of START will set the alarm to trigger off the Err bitreich.org 70 i+ start of the associated event or to-do. A value of END will set Err bitreich.org 70 i+ the alarm to trigger off the end of the associated event or to-do. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Either a positive or negative duration may be specified for the Err bitreich.org 70 i+ "TRIGGER" property. An alarm with a positive duration is Err bitreich.org 70 i+ triggered after the associated start or end of the event or to-do. Err bitreich.org 70 i+ An alarm with a negative duration is triggered before the Err bitreich.org 70 i+ associated start or end of the event or to-do. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "RELATED" property parameter is not valid if the value type of Err bitreich.org 70 i+ the property is set to DATE-TIME (i.e., for an absolute date and Err bitreich.org 70 i+ time alarm trigger). If a value type of DATE-TIME is specified, Err bitreich.org 70 i+ then the property value MUST be specified in the UTC time format. Err bitreich.org 70 i+ If an absolute trigger is specified on an alarm for a recurring Err bitreich.org 70 i+ event or to-do, then the alarm will only trigger for the specified Err bitreich.org 70 i+ absolute DATE-TIME, along with any specified repeating instances. Err bitreich.org 70 i+ Err bitreich.org 70 i+ If the trigger is set relative to START, then the "DTSTART" Err bitreich.org 70 i+ property MUST be present in the associated "VEVENT" or "VTODO" Err bitreich.org 70 i+ calendar component. If an alarm is specified for an event with Err bitreich.org 70 i+ the trigger set relative to the END, then the "DTEND" property or Err bitreich.org 70 i+ the "DTSTART" and "DURATION " properties MUST be present in the Err bitreich.org 70 i+ associated "VEVENT" calendar component. If the alarm is specified Err bitreich.org 70 i+ for a to-do with a trigger set relative to the END, then either Err bitreich.org 70 i+ the "DUE" property or the "DTSTART" and "DURATION " properties Err bitreich.org 70 i+ MUST be present in the associated "VTODO" calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Alarms specified in an event or to-do that is defined in terms of Err bitreich.org 70 i+ a DATE value type will be triggered relative to 00:00:00 of the Err bitreich.org 70 i+ user's configured time zone on the specified date, or relative to Err bitreich.org 70 i+ 00:00:00 UTC on the specified date if no configured time zone can Err bitreich.org 70 i+ be found for the user.

Err bitreich.org 70 i+ Err bitreich.org 70 i+ Description: When a calendar component is created, its sequence Err bitreich.org 70 i+ number is 0. It is monotonically incremented by the "Organizer's" Err bitreich.org 70 i+ CUA each time the "Organizer" makes a significant revision to the Err bitreich.org 70 i+ calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "Organizer" includes this property in an iCalendar object that Err bitreich.org 70 i+ it sends to an "Attendee" to specify the current version of the Err bitreich.org 70 i+ calendar component. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "Attendee" includes this property in an iCalendar object that Err bitreich.org 70 i+ it sends to the "Organizer" to specify the version of the calendar Err bitreich.org 70 i+ component to which the "Attendee" is referring. Err bitreich.org 70 i+ Err bitreich.org 70 i+ A change to the sequence number is not the mechanism that an Err bitreich.org 70 i+ "Organizer" uses to request a response from the "Attendees". The Err bitreich.org 70 i+ "RSVP" parameter on the "ATTENDEE" property is used by the Err bitreich.org 70 i+ "Organizer" to indicate that a response from the "Attendees" is Err bitreich.org 70 i+ requested. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Recurrence instances of a recurring component MAY have different Err bitreich.org 70 i+ sequence numbers.

The components of the value are Err bitreich.org 70 i+ separated by the SEMICOLON character. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The short return status is a PERIOD character separated pair or Err bitreich.org 70 i+ 3-tuple of integers. For example, "3.1" or "3.1.1". The Err bitreich.org 70 i+ successive levels of integers provide for a successive level of Err bitreich.org 70 i+ status code granularity. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The following are initial classes for the return status code.

Recommended Practices Err bitreich.org 70 i+ Err bitreich.org 70 i+ These recommended practices should be followed in order to assure Err bitreich.org 70 i+ consistent handling of the following cases for an iCalendar object. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 1. Content lines longer than 75 octets SHOULD be folded. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 2. When the combination of the "RRULE" and "RDATE" properties in a Err bitreich.org 70 i+ recurring component produces multiple instances having the same Err bitreich.org 70 i+ start DATE-TIME value, they should be collapsed to, and Err bitreich.org 70 i+ considered as, a single instance. If the "RDATE" property is Err bitreich.org 70 i+ specified as a PERIOD value the duration of the recurrence Err bitreich.org 70 i+ instance will be the one specified by the "RDATE" property, and Err bitreich.org 70 i+ not the duration of the recurrence instance defined by the Err bitreich.org 70 i+ "DTSTART" property. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 3. When a calendar user receives multiple requests for the same Err bitreich.org 70 i+ calendar component (e.g., REQUEST for a "VEVENT" calendar Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 147] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ component) as a result of being on multiple mailing lists Err bitreich.org 70 i+ specified by "ATTENDEE" properties in the request, they SHOULD Err bitreich.org 70 i+ respond to only one of the requests. The calendar user SHOULD Err bitreich.org 70 i+ also specify (using the "MEMBER" parameter of the "ATTENDEE" Err bitreich.org 70 i+ property) of which mailing list they are a member. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 4. An implementation can truncate a "SUMMARY" property value to 255 Err bitreich.org 70 i+ octets, but it MUST NOT truncate the value in the middle of a Err bitreich.org 70 i+ UTF-8 multi-octet sequence. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 5. If seconds of the minute are not supported by an implementation, Err bitreich.org 70 i+ then a value of "00" SHOULD be specified for the seconds Err bitreich.org 70 i+ component in a time value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 6. "TZURL" values SHOULD NOT be specified as a file URI type. This Err bitreich.org 70 i+ URI form can be useful within an organization, but is problematic Err bitreich.org 70 i+ in the Internet. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 7. Some possible English values for "CATEGORIES" property include: Err bitreich.org 70 i+ "ANNIVERSARY", "APPOINTMENT", "BUSINESS", "EDUCATION", "HOLIDAY", Err bitreich.org 70 i+ "MEETING", "MISCELLANEOUS", "NON-WORKING HOURS", "NOT IN OFFICE", Err bitreich.org 70 i+ "PERSONAL", "PHONE CALL", "SICK DAY", "SPECIAL OCCASION", Err bitreich.org 70 i+ "TRAVEL", "VACATION". Categories can be specified in any Err bitreich.org 70 i+ registered language. Err bitreich.org 70 i+ Err bitreich.org 70 i+ 8. Some possible English values for the "RESOURCES" property Err bitreich.org 70 i+ include: "CATERING", "CHAIRS", "COMPUTER PROJECTOR", "EASEL", Err bitreich.org 70 i+ "OVERHEAD PROJECTOR", "SPEAKER PHONE", "TABLE", "TV", "VCR", Err bitreich.org 70 i+ "VIDEO PHONE", "VEHICLE". Resources can be specified in any Err bitreich.org 70 i+ registered language. Err bitreich.org 70 i+ Err bitreich.org 70 i+6. Internationalization Considerations Err bitreich.org 70 i+ Err bitreich.org 70 i+ Applications MUST generate iCalendar streams in the UTF-8 charset and Err bitreich.org 70 i+ MUST accept an iCalendar stream in the UTF-8 or US-ASCII charset. Err bitreich.org 70 i+ Err bitreich.org 70 i+7. Security Considerations Err bitreich.org 70 i+ Err bitreich.org 70 i+ Because calendaring and scheduling information is very privacy- Err bitreich.org 70 i+ sensitive, the protocol used for the transmission of calendaring and Err bitreich.org 70 i+ scheduling information should have capabilities to protect the Err bitreich.org 70 i+ information from possible threats, such as eavesdropping, replay, Err bitreich.org 70 i+ message insertion, deletion, modification, and man-in-the-middle Err bitreich.org 70 i+ attacks. Err bitreich.org 70 i+ Err bitreich.org 70 i+ As this document only defines the data format and media type of text/ Err bitreich.org 70 i+ calendar that is independent of any calendar service or protocol, it Err bitreich.org 70 i+ is up to the actual protocol specifications such as iTIP [2446bis], Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+Desruisseaux Standards Track [Page 148] Err bitreich.org 70 i+ Err bitreich.org 70 i+RFC 5545 iCalendar September 2009 Err bitreich.org 70 i+ Err bitreich.org 70 i+ Err bitreich.org 70 i+ iMIP [2447bis], and "Calendaring Extensions to WebDAV (CalDAV)" Err bitreich.org 70 i+ [RFC4791] to describe the threats that the above attacks present, as Err bitreich.org 70 i+ well as ways in which to mitigate them.

IANA Considerations Err bitreich.org 70 i+ Err bitreich.org 70 i+8.1. iCalendar Media Type Registration Err bitreich.org 70 i+ Err bitreich.org 70 i+ The Calendaring and Scheduling Core Object Specification is intended Err bitreich.org 70 i+ for use as a MIME content type. Err bitreich.org 70 i+ Err bitreich.org 70 i+ To: ietf-types@iana.org Err bitreich.org 70 i+ Err bitreich.org 70 i+ Subject: Registration of media type text/calendar Err bitreich.org 70 i+ Err bitreich.org 70 i+ Type name: text Err bitreich.org 70 i+ Err bitreich.org 70 i+ Subtype name: calendar Err bitreich.org 70 i+ Err bitreich.org 70 i+ Required parameters: none Err bitreich.org 70 i+ Err bitreich.org 70 i+ Optional parameters: charset, method, component, and optinfo Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "charset" parameter is defined in [RFC2046] for subtypes of Err bitreich.org 70 i+ the "text" media type. It is used to indicate the charset used in Err bitreich.org 70 i+ the body part. The charset supported by this revision of Err bitreich.org 70 i+ iCalendar is UTF-8. The use of any other charset is deprecated by Err bitreich.org 70 i+ this revision of iCalendar; however, note that this revision Err bitreich.org 70 i+ requires that compliant applications MUST accept iCalendar streams Err bitreich.org 70 i+ using either the UTF-8 or US-ASCII charset. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "method" parameter is used to convey the iCalendar object Err bitreich.org 70 i+ method or transaction semantics for the calendaring and scheduling Err bitreich.org 70 i+ information. It also is an identifier for the restricted set of Err bitreich.org 70 i+ properties and values of which the iCalendar object consists. The Err bitreich.org 70 i+ parameter is to be used as a guide for applications interpreting Err bitreich.org 70 i+ the information contained within the body part. It SHOULD NOT be Err bitreich.org 70 i+ used to exclude or require particular pieces of information unless Err bitreich.org 70 i+ the identified method definition specifically calls for this Err bitreich.org 70 i+ behavior. Unless specifically forbidden by a particular method Err bitreich.org 70 i+ definition, a text/calendar content type can contain any set of Err bitreich.org 70 i+ properties permitted by the Calendaring and Scheduling Core Object Err bitreich.org 70 i+ Specification. The "method" parameter MUST be specified and MUST Err bitreich.org 70 i+ be set to the same value as the "METHOD" component property of the Err bitreich.org 70 i+ iCalendar objects of the iCalendar stream if and only if the Err bitreich.org 70 i+ iCalendar objects in the iCalendar stream all have a "METHOD" Err bitreich.org 70 i+ component property set to the same value.

If the iCalendar object contains Err bitreich.org 70 i+ more than one calendar component type, then multiple component Err bitreich.org 70 i+ parameters MUST be specified. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The value for the "component" parameter is defined as follows: Err bitreich.org 70 i+ Err bitreich.org 70 i+ component = "VEVENT" Err bitreich.org 70 i+ / "VTODO" Err bitreich.org 70 i+ / "VJOURNAL" Err bitreich.org 70 i+ / "VFREEBUSY" Err bitreich.org 70 i+ / "VTIMEZONE" Err bitreich.org 70 i+ / iana-token Err bitreich.org 70 i+ / x-name Err bitreich.org 70 i+ Err bitreich.org 70 i+ The "optinfo" parameter conveys optional information about the Err bitreich.org 70 i+ iCalendar object within the body part. This parameter can only Err bitreich.org 70 i+ specify semantics already specified by the iCalendar object and Err bitreich.org 70 i+ that can be otherwise determined by parsing the body part. In Err bitreich.org 70 i+ addition, the optional information specified by this parameter Err bitreich.org 70 i+ MUST be consistent with that information specified by the Err bitreich.org 70 i+ iCalendar object. For example, it can be used to convey the Err bitreich.org 70 i+ "Attendee" response status to a meeting request. The parameter Err bitreich.org 70 i+ value consists of a string value. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The parameter can be specified multiple times. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The value for the "optinfo" parameter is defined as follows: Err bitreich.org 70 i+ Err bitreich.org 70 i+ optinfo = infovalue / qinfovalue Err bitreich.org 70 i+ Err bitreich.org 70 i+ infovalue = iana-token / x-name Err bitreich.org 70 i+ Err bitreich.org 70 i+ qinfovalue = DQUOTE (infovalue) DQUOTE Err bitreich.org 70 i+ Err bitreich.org 70 i+ Encoding considerations: This media type can contain 8bit Err bitreich.org 70 i+ characters, so the use of quoted-printable or base64 MIME Content- Err bitreich.org 70 i+ Transfer-Encodings might be necessary when iCalendar objects are Err bitreich.org 70 i+ transferred across protocols restricted to the 7bit repertoire. Err bitreich.org 70 i+ Note that a text valued property in the content entity can also Err bitreich.org 70 i+ have content encoding of special characters using a BACKSLASH Err bitreich.org 70 i+ character escapement technique. This means that content values Err bitreich.org 70 i+ can end up being encoded twice.

Err bitreich.org 70 i+ Err bitreich.org 70 i+8.2.1. iCalendar Elements Registration Procedure Err bitreich.org 70 i+ Err bitreich.org 70 i+ The IETF will create a mailing list, icalendar@ietf.org, which can be Err bitreich.org 70 i+ used for public discussion of iCalendar elements proposals prior to Err bitreich.org 70 i+ registration. Use of the mailing list is strongly encouraged. The Err bitreich.org 70 i+ IESG will appoint a designated expert who will monitor the Err bitreich.org 70 i+ icalendar@ietf.org mailing list and review registrations. Err bitreich.org 70 i+ Err bitreich.org 70 i+ Registration of new iCalendar elements MUST be reviewed by the Err bitreich.org 70 i+ designated expert and published in an RFC. A Standards Track RFC is Err bitreich.org 70 i+ REQUIRED for the registration of new value data types that modify Err bitreich.org 70 i+ existing properties, as well as for the registration of participation Err bitreich.org 70 i+ status values to be used in "VEVENT" calendar components. A Err bitreich.org 70 i+ Standards Track RFC is also REQUIRED for registration of iCalendar Err bitreich.org 70 i+ elements that modify iCalendar elements previously documented in a Err bitreich.org 70 i+ Standards Track RFC. Err bitreich.org 70 i+ Err bitreich.org 70 i+ The registration procedure begins when a completed registration Err bitreich.org 70 i+ template, defined in the sections below, is sent to Err bitreich.org 70 i+ icalendar@ietf.org and iana@iana.org. The designated expert is Err bitreich.org 70 i+ expected to tell IANA and the submitter of the registration within Err bitreich.org 70 i+ two weeks whether the registration is approved, approved with minor Err bitreich.org 70 i+ changes, or rejected with cause. When a registration is rejected Err bitreich.org 70 i+ with cause, it can be re-submitted if the concerns listed in the Err bitreich.org 70 i+ cause are addressed. Decisions made by the designated expert can be Err bitreich.org 70 i+ appealed to the IESG Applications Area Director, then to the IESG. Err bitreich.org 70 i+ They follow the normal appeals procedure for IESG decisions. Err bitreich.org 70 i+ Err bitreich.org 70 i+8.2.2.
