<section1 topic='Introduction'>
|
|
<p>&xep0120; defines a protocol for capturing granular information (or "infobits") about users, servers, services, rooms, nodes, commands, files, and other phenomena on the Jabber/XMPP network; however, that document defines the protocol only, not the infobits themselves. This document specifies how to encapsulate one sort of metadata in infobits: the common metadata elements defined by the &DUBLINCORE;. Note well that this document is decidedly <em>not</em> meant to provide an exhaustive catalog of possible infobits. Future registrations, whether in XMPP Extension Protocol specifications or direct submissions to the ®ISTRAR;, will specify additional infobits.</p>
|

</section1>

|
<section1 topic='Dublin Core Metadata Terms'>
|
|
<p>The Dublin Core Metadata Initiative defines a number of common elements and element refinements that can be used to specify metadata about entities (especially but not exclusively publications). The semantics of any Dublin Core term can be represented as a Jabber infobit, where the infobit keyname consists of the term name (not label) prepended by a 'DC' prefix and a '.' separator character. Thus "DC.creator" is a valid infobit name and can be used to describe, for example, an IM user's relationship to the URI identifying the user's homepage or weblog. Infobit keynames beginning with the 'DC' prefix are reserved for &dcmiterms; only (the canonical list of these terms is available from the Dublin Core Metadata Initiative and is included here only for explanatory purposes).</p>
