Such interchanges frequ 313ently include the exchange of informal information, such as business cards, telephone numbers, addresses, dates and times of appointments, etc. Augmenting PDI with electronics and telecommunications can help ensure that information is quickly and reliably 314 communicated, stored, organized and easily located when needed. 315\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar Personal information, by nature, is complex and diverse. Currently, proprietary standards exist to structure some types of PDI information, but no single, open specification comprehensively ad 316dresses the needs of collecting and communicating PDI information across many common communication channels such as telephones, voice-mail, e-mail, and face-to-face meetings. {\b\i\f30\fs18 versit } 317 is developing a comprehensive family of PDI technologies based on open specifications and interoperability agreements to help meet this technology need. 318\par {\*\bkmkstart _Toc346992805}{\*\bkmkstart _Toc365129065}{\*\bkmkstart _Toc367165326}{\pntext\pard\plain\b\f9\fs28\cf1 1.1\tab}\pard\plain \s2\sb380\sa160\sl-320\slmult0\keepn\nowidctlpar\tqr\tx432\tx864{\*\pn \pnlvl2\pndec\pnprev1\pnstart1\pnsp144 } 319\b\f9\fs28\cf1 Overview{\*\bkmkend _Toc346992805}{\*\bkmkend _Toc365129065}{\*\bkmkend _Toc367165326} 320\par \pard\plain \s15\li864\sb100\sl-260\slmult0\nowidctlpar \f8\fs20\cf1 This specification defines a format for an electronic calendaring and scheduling ({\b\i vCalendar}) format. The vCalendar format allows for the capture of information normall 321y stored within a calendaring and scheduling application; such as a Personal Information Manager or a Group Scheduling product. 322\par The format is suitable as an interchange format between applications or systems. The format is defined independent of the particular method used to transport it. The transport for this exchange might be a file system, point-to-point asynchronous communica 323tion, wired-network transport, or some form of unwired transport. 324\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar A vCalendar is a data stream consisting of one or more vCalenda 325r objects. The individual vCalendar definitions can be identified and parsed within the data stream. The vCalendar data stream may exist as a persistent form in a file system, document management system, network connection between two network endpoints, o 326r in any other digital transport that has an abstraction of a stream of bytes. 327\par Conceptually, a {\i vCalendar Writer} creates vCalendar data streams and a {\i vCalendar Reader} interprets vCalendar data streams. The vCalendar Reader and Writer may be implemented as a 328single application or as separate applications. It is not the intent of this specification to define the implementation of these processes beyond some fundamental capabilities related to the format of the vCalendar data stream and a common set of conforma 329nce requirements. 330\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar 331This specification provides for a clear-text encoding. The specification also includes a formal grammar for the clear-text encoding to aid in the implementation of parsers and to serve as the definitive reference when ambiguities or questi 332ons arise in interpreting the descriptive prose definition of the specification. 333\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar 334The clear-text encoding of this specification can be used in environments which are constrained to 7-bit transfer encodings, short line lengths, and low bandwidth. In addition, the encoding is simple in order to facilitate the implementation of reader and 335 writer applications on small platforms, such as Personal Digital Assistants (PDA), cellular telephones, or alphanumeric pagers. 336\par {\*\bkmkstart _Toc346992806}{\*\bkmkstart _Toc365129066}{\*\bkmkstart _Toc367165327}{\pntext\pard\plain\b\f9\fs28\cf1 1.2\tab}\pard\plain \s2\sb380\sa160\sl-320\slmult0\keepn\nowidctlpar\tqr\tx432\tx864{\*\pn \pnlvl2\pndec\pnprev1\pnstart1\pnsp144 } 337\b\f9\fs28\cf1 Scope{\*\bkmkend _Toc346992806}{\*\bkmkend _Toc365129066}{\*\bkmkend _Toc367165327} 338\par \pard\plain \s15\li864\sb100\sl-260\slmult0\nowidctlpar \f8\fs20\cf1 The vCalendar is intended to be used for exchanging information about {\b\i event} and {\b\i todo} 339 types of calendaring and scheduling entities. An event is a calendaring and scheduling entity that represents a scheduled amount of time on a calendar. For example, it may be an activity; such as a one-hour, department meeting from 8 AM to 9 AM, tomorrow 340. A todo is a calendaring and scheduling entity that represents an action-item or assignment. For example, it may be an item of work assigned to an individual; such as \ldblquote turn in travel expense today\rdblquote . 341\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar In today\rquote s bus 342iness environment, this information is typically kept on a paper-based day-planner or calendar. More and more, this type of information is being also managed within electronic Personal Information Manager or Group Scheduling products. It is appropriate, t 343hen that this specification define this information in terms of a paradigm based on a calendaring and scheduling event and todo entities. 344\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar Prior to the introduction of the vCalendar specification, users of such applications typically had to re-key the origi 345nal information, often transcribing it from paper day-planners, scraps of paper or electronic mail messages. With the advent of the vCalendar specification, this information can be exchanged in an automated and consistent fashion. 346\par The basis for this specification have their origin in openly defined, industry specifications; such as the X.400 API Association\rquote 347s Calendaring and Scheduling API (CSA). In addition, this specification has capabilities that were derived from the experience of multi-vendor demonstrations of this capability. 348\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar 349The specification of all date and time values are defined in terms of the ISO 8601 standard for representation of dates and times. The ISO 8601 standard supersedes all other international standards defined at the time this specification was drafted. 350 351\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar 352Personal data applications such as Personal Information Managers (PIM) often provide an import/export capability using Comma Separated Value (CSV) or Tab Delimited Files (TDF) formats. However, these solutions do not preserve the intent 353 of the originating application. When a CSV and TDF format is used by a PIM, the meta-data or semantics of the originating object are only apparent to a similar version of the originating application. Exchange of data between such applications is another 354important application of an industry-standard specification for an electronic calendaring and scheduling interchange format, such as the vCalendar specification. 355\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar This specification is intended to be used as a format for exchange of calendaring and schedulin 356g information from one product to another. This exchange may take place using desktop application interaction techniques; such as a file system FILE-OPEN or FILE-SAVE-AS functions, an operating systems clipboard CUT or COPY or PASTE operations, or a user 357interface DRAG and DROP interaction. In addition, this exchange may take place using a wired or wireless network transport; such as LAN or WAN protocols, switched telephone circuits, IrDA-based infra-red \ldblquote beaming\rdblquote 358 of data, or emerging cellular data services. In any of these example cases, the vCalendar format is intended to be a transport- and platform-independent format for exchanging calendaring and scheduling personal data. 359\par {\*\bkmkstart _Toc346992807}{\*\bkmkstart _Toc365129067}{\*\bkmkstart _Toc367165328}{\pntext\pard\plain\b\f9\fs28\cf1 1.3\tab}\pard\plain \s2\sb380\sa160\sl-320\slmult0\keepn\nowidctlpar\tqr\tx432\tx864{\*\pn \pnlvl2\pndec\pnprev1\pnstart1\pnsp144 } 360\b\f9\fs28\cf1 Contents{\*\bkmkend _Toc346992807}{\*\bkmkend _Toc365129067}{\*\bkmkend _Toc367165328} 361\par \pard\plain \s15\li864\sb100\sl-260\slmult0\widctlpar \f8\fs20\cf1 This specification is separated into eight sections: 362\par \pard\plain \s22\fi-289\li1224\sb100\sa100\sl-260\slmult0\nowidctlpar\tx1224\tldot\tx3685 \f8\fs20\cf1 \bullet \tab \ldblquote Section 1 : Introduction\rdblquote 363 introduces PDI and the vCalendar specification with an overview, scope statement and section on definitions and abbreviations. 364\par \bullet \tab \ldblquote Section 2 : vCalendar\rdblquote defines the semantics and syntax for a clear-text encoding of the vCalendar. 365\par \pard \s22\fi-289\li1224\sb100\sa100\sl-260\slmult0\nowidctlpar\tx1224\tldot\tx3685 \bullet \tab \ldblquote Section 3: Internet Recommendations\rdblquote 366 specifies a set of guidelines to facilitate the exchange of vCalendar objects over Internet protocols such as HTTP using HTML and SMTP using MIME. 367\par \bullet \tab \ldblquote Section 4 : UI Support Recommendations\rdblquote 368 specifies a set of guidelines to facilitate the exchange of vCalendar objects at the desktop user interface using the file system, clipboard and drag/drop capabilities of the operating system. 369\par \pard \s22\fi-289\li1224\sb100\sa100\sl-260\slmult0\nowidctlpar\tx1224\tldot\tx3685 \bullet \tab \ldblquote Section 5 : Conformance\rdblquote defines minimum conformance requirements to consider while developing support for this vCalendar specification. 370 371\par \bullet \tab \ldblquote Section 6 : Extended Recurrence Rule Grammar\rdblquote defines reference information on an extended recurrence rule grammar, copied from the XAPIA CSA Specification. 372\par {\*\bkmkstart _Toc346992808}{\*\bkmkstart _Toc365129068}{\*\bkmkstart _Toc367165329}{\pntext\pard\plain\b\f9\fs28\cf1 1.4\tab}\pard\plain \s2\sb380\sa160\sl-320\slmult0\keepn\nowidctlpar\tqr\tx432\tx864{\*\pn \pnlvl2\pndec\pnprev1\pnstart1\pnsp144 } 373\b\f9\fs28\cf1 Definitions and Abbreviations{\*\bkmkend _Toc346992808}{\*\bkmkend _Toc365129068}{\*\bkmkend _Toc367165329} 374\par \pard\plain \s15\li864\sb100\sl-260\slmult0\widctlpar \f8\fs20\cf1 Definitions and abbreviations used within this specification follow. 375\par \pard\plain \s32\fi-432\li1295\sb100\sa100\sl-260\slmult0\widctlpar \f8\fs20\cf1 {\b\i API}: Application Programming Interface 376\par {\b\i Electronic Calendar}: Also know as vCalendar. 377\par \pard \s32\fi-432\li1295\sb100\sa100\sl-260\slmult0\widctlpar {\b\i FPI}: Formal Public Identifier.

It provides a method of capturing the scope of the access the calendar owner intends for information within an individual calendar 889entry. The access classification of an individual vCalendar entity is useful when measured along with the other security components of a ca 890lendar system (e.g., user authorization, access rights, access role, etc.). Hence, the semantics of the individual access classifications can not be completely defined by this specification. Additionally, due to the \ldblquote blind\rdblquote 891 nature of most exchange process 892es using this specification, these entity classifications can not serve as an enforcement statement for a system receiving a vCalendar data stream. Rather, they provide a method for capturing the intention of the calendar owner for the access to the calen 893dar entry. 894\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar The following is an example of this property: 895\par \pard\plain \s25\li1224\sb100\sl-200\slmult0\nowidctlpar\tx1440\tx1800\tx2160\tx2520\tx2880\tx3240\tx3600\tx3960\tx4320\tx4680\tx5040\tx5400\tx5760\tx6120\tx6480\tx6840\tx7200\tx7560\tx7920\tx8280\tx8640 \f3\fs16\cf1 CLASS:PUBLIC 896\par \pard\plain \s15\li864\sb100\sl-260\slmult0\nowidctlpar \f8\fs20\cf1 The property can have the following values: 897\par 898\par \trowd \trgaph108\trleft1260 \clbrdrt\brdrs\brdrw30\brdrcf1 \clbrdrl\brdrs\brdrw15\brdrcf1 \clbrdrb\brdrs\brdrw45\brdrcf1 \cellx4379\clbrdrt\brdrs\brdrw30\brdrcf1 \clbrdrb\brdrs\brdrw45\brdrcf1 \clbrdrr\brdrs\brdrw15 \cellx5896 \pard\plain 899\s48\sb80\sa80\sl-200\slmult0\keepn\nowidctlpar\intbl \b\f9\fs18\cf1 Description\cell \pard \s48\sb80\sa80\sl-200\slmult0\keepn\nowidctlpar\intbl Property Value\cell \pard\plain \widctlpar\intbl \f4\fs20 \row \trowd \trgaph108\trleft1260 \clbrdrl 900\brdrs\brdrw15\brdrcf1 \cellx4379\clbrdrr\brdrs\brdrw15\brdrcf1 \cellx5896 \pard\plain \s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 \f8\fs16\cf1 Indicates general, public access.\cell \pard \s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 901PUBLIC\cell \pard\plain \widctlpar\intbl \f4\fs20 \row \pard\plain \s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 \f8\fs16\cf1 Indicates restricted, private access.\cell \pard \s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 PRIVATE\cell 902\pard\plain \widctlpar\intbl \f4\fs20 \row \trowd \trgaph108\trleft1260 \clbrdrl\brdrs\brdrw15\brdrcf1 \clbrdrb\brdrs\brdrw30\brdrcf1 \cellx4379\clbrdrb\brdrs\brdrw30\brdrcf1 \clbrdrr\brdrs\brdrw15\brdrcf1 \cellx5896 \pard\plain 903\s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 \f8\fs16\cf1 Indicates very restricted, confidential access.\cell \pard \s51\sb80\sa80\sl-220\slmult0\nowidctlpar\intbl\tx144 CONFIDENTIAL\cell \pard\plain \widctlpar\intbl \f4\fs20 \row \pard\plain 904\s15\li864\sb100\sl-260\slmult0\nowidctlpar \f8\fs20\cf1 905\par The default value for this property is PUBLIC. 906\par Support for this property is optional for implementations conforming to this specification. 907\par {\*\bkmkstart _Toc365129103}{\*\bkmkstart _Toc367165364}{\pntext\pard\plain\b\f9\cf1\kerning28 2.3.6\tab}\pard\plain \s3\sb280\sa140\sl-280\slmult0\keepn\nowidctlpar\tqr\tx432\tx864{\*\pn \pnlvl3\pndec\pnprev1\pnstart1\pnsp144 {\pntxtb .}} 908\b\f9\cf1\kerning28 Date/Time Created{\*\bkmkend _Toc365129103}{\*\bkmkend _Toc367165364} 909\par \pard\plain \s15\li864\sb100\sl-260\slmult0\nowidctlpar \f8\fs20\cf1 This property is identified by the property name {\b DCREATED}.

A value of zero (ASCII decimal 48) guaranttes that the entry will blocks time and will be factored into a free time search. A value of 1127one (ASCII decimal 49) specifies that the entry will not block time and will not be factored into a free time search.

Homepages can be used as a web-based document for publishing public events. The events can be easily formatt 1406ed into vCalendar objects for transfer between the server and a requesting browser. The following examples are provided to illustrate possible scenarios where a non-standard \ldblquote text/x-vCalendar\rdblquote 1407 MIME type/subtype corresponding the vCalendar can be used to transfer calendaring and scheduling information across the World Wide Web. 1408\par \pard \s15\li864\sb100\sl-260\slmult0\nowidctlpar The following example demonstrates how a vCalendar object can be included in an HTML document or Web page.
