i-1. 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- 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- 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-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- 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-3.1.2. 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- 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]. Inline binary content SHOULD only be used in applications Err bitreich.org 70
i- whose special circumstances demand that an iCalendar object be Err bitreich.org 70
i- expressed as a single entity. A property containing inline binary Err bitreich.org 70
i- content information MUST specify the "ENCODING" property parameter. Err bitreich.org 70
i- Binary content information placed external to the iCalendar object Err bitreich.org 70
i- MUST be referenced by a uniform resource identifier (URI). Err bitreich.org 70
i- Err bitreich.org 70
i- The following example specifies an "ATTACH" property that references Err bitreich.org 70
i- an attachment external to the iCalendar object with a URI reference: Err bitreich.org 70

i- Err bitreich.org 70
i- Property parameter values that contain the COLON, SEMICOLON, or COMMA Err bitreich.org 70
i- character separators MUST be specified as quoted-string text values. Err bitreich.org 70

i- The "DATE-TIME" value type is used to identify values that contain 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- 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- ordered in any particular sequence. Individual rule parts MUST Err bitreich.org 70
i- only be specified once. Compliant applications MUST accept rule Err bitreich.org 70
i- parts ordered in any sequence, but to ensure backward Err bitreich.org 70
i- compatibility with applications that pre-date this revision of Err bitreich.org 70
i- iCalendar the FREQ rule part MUST be the first rule part specified Err bitreich.org 70
i- in a RECUR value. Err bitreich.org 70
i- Err bitreich.org 70
i- The FREQ rule part identifies the type of recurrence rule. This Err bitreich.org 70
i- rule part MUST be specified in the recurrence rule. Valid values Err bitreich.org 70
i- include SECONDLY, to specify repeating events based on an interval Err bitreich.org 70
i- of a second or more; MINUTELY, to specify repeating events based Err bitreich.org 70
i- on an interval of a minute or more; HOURLY, to specify repeating Err bitreich.org 70

i- Err bitreich.org 70
i- The INTERVAL rule part contains a positive integer representing at Err bitreich.org 70
i- which intervals the recurrence rule repeats. The default value is Err bitreich.org 70
i- "1", meaning every second for a SECONDLY rule, every minute for a Err bitreich.org 70
i- MINUTELY rule, every hour for an HOURLY rule, every day for a Err bitreich.org 70
i- DAILY rule, every week for a WEEKLY rule, every month for a Err bitreich.org 70
i- MONTHLY rule, and every year for a YEARLY rule. 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. The value of the UNTIL rule part MUST have the same Err bitreich.org 70
i- value type as the "DTSTART" property. 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. In the Err bitreich.org 70
i- case of the "STANDARD" and "DAYLIGHT" sub-components the UNTIL Err bitreich.org 70
i- rule part MUST always be specified as a date with UTC time. If Err bitreich.org 70
i- specified as a DATE-TIME value, then it MUST be specified in a UTC Err bitreich.org 70
i- time format. 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. Err bitreich.org 70
i- These rule parts MUST be ignored in RECUR value that violate the Err bitreich.org 70
i- above requirement (e.g., generated by applications that pre-date Err bitreich.org 70
i- this revision of iCalendar). Err bitreich.org 70
i- Err bitreich.org 70
i- The BYDAY rule part specifies a COMMA-separated list of days of Err bitreich.org 70
i- the week; SU indicates Sunday; MO indicates Monday; TU indicates Err bitreich.org 70
i- Tuesday; WE indicates Wednesday; TH indicates Thursday; FR Err bitreich.org 70
i- indicates Friday; and SA indicates Saturday. Err bitreich.org 70
i- Err bitreich.org 70
i- Each BYDAY value can also be preceded by a positive (+n) or Err bitreich.org 70
i- negative (-n) integer. If present, this indicates the nth Err bitreich.org 70
i- occurrence of a specific day within the MONTHLY or YEARLY "RRULE". Err bitreich.org 70

i- For example, within a MONTHLY rule, +1MO (or simply 1MO) Err bitreich.org 70
i- represents the first Monday within the month, whereas -1MO Err bitreich.org 70
i- represents the last Monday of the month. 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. For example, within a MONTHLY rule, MO Err bitreich.org 70
i- represents all Mondays within the month. The BYDAY rule part MUST Err bitreich.org 70
i- NOT be specified with a numeric value when the FREQ rule part is Err bitreich.org 70
i- not set to MONTHLY or YEARLY. Furthermore, the BYDAY rule part Err bitreich.org 70
i- MUST NOT be specified with a numeric value with the FREQ rule part Err bitreich.org 70
i- set to YEARLY when the BYWEEKNO rule part is specified. 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- The BYMONTHDAY rule part MUST NOT be specified when the FREQ rule Err bitreich.org 70
i- part is set to WEEKLY. 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- 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- 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- 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. BYxxx Err bitreich.org 70
i- rule parts for a period of time less than the frequency generally Err bitreich.org 70
i- increase or expand the number of occurrences of the recurrence. 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- 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- 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- 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- Err bitreich.org 70
i- 070000Z Err bitreich.org 70
i- 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, the calendar Err bitreich.org 70
i- component can specify an event, a to-do, a journal entry, time zone Err bitreich.org 70

i- Description: A "VEVENT" calendar component is a grouping of Err bitreich.org 70
i- component properties, possibly including "VALARM" calendar Err bitreich.org 70
i- components, that represents a scheduled amount of time on a Err bitreich.org 70
i- calendar. 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. Alternately, the event can have its Time Transparency 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. However, "VEVENT" calendar components can be Err bitreich.org 70
i- related to each other or to a "VTODO" or to a "VJOURNAL" calendar Err bitreich.org 70
i- component with the "RELATED-TO" property. Err bitreich.org 70

i- * If observance is known to have an effective end date, the Err bitreich.org 70
i- "UNTIL" recurrence rule parameter MUST be used to specify the Err bitreich.org 70
i- last valid onset of this observance (i.e., the UNTIL DATE-TIME Err bitreich.org 70

i- the "VALARM" calendar component in the following ways: Err bitreich.org 70
i- Err bitreich.org 70
i- When the action is "AUDIO", the alarm can also include one and Err bitreich.org 70
i- only one "ATTACH" property, which MUST point to a sound resource, Err bitreich.org 70
i- which is rendered when the alarm is triggered. 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- 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. If an "ATTACH" Err bitreich.org 70

i- the CUA or other entity responsible for playing the sound may Err bitreich.org 70
i- choose a fallback action, such as playing a built-in default Err bitreich.org 70
i- sound, or playing no sound at all. 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. Err bitreich.org 70
i- Err bitreich.org 70
i- In an EMAIL alarm, the intended alarm effect is for an email Err bitreich.org 70
i- message to be composed and delivered to all the addresses Err bitreich.org 70
i- specified by the "ATTENDEE" properties in the "VALARM" calendar Err bitreich.org 70
i- component. The "DESCRIPTION" property of the "VALARM" calendar Err bitreich.org 70
i- component MUST be used as the body text of the message, and the Err bitreich.org 70
i- "SUMMARY" property MUST be used as the subject text. Any "ATTACH" Err bitreich.org 70
i- properties in the "VALARM" calendar component SHOULD be sent as Err bitreich.org 70
i- attachments to the message. Err bitreich.org 70
i- Err bitreich.org 70
i- Note: Implementations should carefully consider whether they Err bitreich.org 70
i- accept alarm components from untrusted sources, e.g., when Err bitreich.org 70
i- importing calendar objects from external sources. One Err bitreich.org 70
i- reasonable policy is to always ignore alarm components that the Err bitreich.org 70
i- calendar user has not set herself, or at least ask for Err bitreich.org 70
i- confirmation in such a case. Err bitreich.org 70
i- Err bitreich.org 70

i- Description: An access classification is only one component of the Err bitreich.org 70
i- general security system within a calendar application. 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. Additionally, Err bitreich.org 70
i- due to the "blind" nature of most exchange processes using this Err bitreich.org 70
i- memo, these access classifications cannot serve as an enforcement Err bitreich.org 70
i- statement for a system receiving an iCalendar object. Rather, Err bitreich.org 70
i- they provide a method for capturing the intention of the calendar Err bitreich.org 70
i- owner for the access to the calendar component. If not specified Err bitreich.org 70
i- in a component that allows this property, the default value is 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- 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- Err bitreich.org 70
i- Description: The "UID" itself MUST be a globally unique identifier. 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-3.8.5.3. Recurrence Rule Err bitreich.org 70
i- Err bitreich.org 70
i- Property Name: RRULE Err bitreich.org 70
i- Err bitreich.org 70
i- Purpose: This property defines a rule or repeating pattern for Err bitreich.org 70
i- recurring events, to-dos, journal entries, or time zone Err bitreich.org 70
i- definitions. Err bitreich.org 70
i- Err bitreich.org 70
i- Value Type: RECUR Err bitreich.org 70
i- Err bitreich.org 70
i- Property Parameters: IANA and non-standard property parameters can Err bitreich.org 70
i- be specified on this property. Err bitreich.org 70
i- Err bitreich.org 70
i- Conformance: This property can be specified in recurring "VEVENT", Err bitreich.org 70
i- "VTODO", and "VJOURNAL" calendar components as well as in the Err bitreich.org 70
i- "STANDARD" and "DAYLIGHT" sub-components of the "VTIMEZONE" Err bitreich.org 70
i- calendar component, but it SHOULD NOT be specified more than once. 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 defines Err bitreich.org 70
i- the first instance in the recurrence set. 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. This implies that start DATE- Err bitreich.org 70
i- TIME values specified by "EXDATE" properties take precedence over Err bitreich.org 70
i- those specified by inclusion properties (i.e., "RDATE" and Err bitreich.org 70
i- "RRULE"). Where 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 "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. The Err bitreich.org 70
i- duration of a specific recurrence may be modified in an exception Err bitreich.org 70
i- component or simply by using an "RDATE" property of PERIOD value Err bitreich.org 70
i- type. 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- 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-5. 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- 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- 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-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
