This document specifies the format and semantics associated to a 'file' event package that allows SIP endpoints to publish the availability of files. A file can be, for example, images, video files, audio files, etc. The event package reuses the eXtended Mark-up Language (XML) 'file-metadata' document to provide file descriptions. This event package also allows SIP endpoints to subscribe to changes in the availability of files, or perform searches for the availability and location of a given file. Support for partial notifications and publications is also accomplished by using XML patch operations.
