Abstract The IETF has defined a standard format for exchanging calendaring and scheduling data, called iCalendar. This format is useful for exchange of personal calendar data across the Internet, as well as in non- Internet environments. In a number of environments where the iCalendar will be used, the format type and version needs to be identified. For example, when registering the iCalendar as a format for memory-based "clipboard" or "drag/drop" user interface interactions. For these cases, a definitive formal public identifier (FPI) for the iCalendar will be required. This memo defined the FPI to be used when referring to the version 2.0 (the value in the "VERSION" property) of the iCalendar format. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY" and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119]. 1. Introduction This memo defines a FPI for iCalendar. The format corresponds to the version defined by the [RFC 2445] specification and identified in an Dawson/Hoffman 1 Expires October 1999 Internet Draft iCalendar FPI April 1, 1999 iCalendar object by the "VERSION:2.0" property:value pair. An FPI is an identifier that is used to uniquely identify an entity. The syntax for a FPI is defined in [ISO 9070]. The FPI defined by this memo can be used to register the version 2.0 of the iCalendar format in an operating system object registry so that the format can be uniquely referenced within that environment. In addition, this FPI can be used to refer to the iCalendar notation in representation grammars, such as that defined by [XML]. 2. iCalendar v2.0 FPI The public identified defined by this memo is a non-registered FPI, as defined by [ISO 9070]. The FPI is defined by the following text string. "-//IETF//NOTATION RFC 2445/iCalendar//EN" This FPI SHOULD be used where ever a reference is needed to the standard iCalendar format defined by [RFC 2445]. For example, the following shows how it would be used in an XML notation declaration: 3. Security Considerations There are no security issues in the material discussed in this memo. 4.
