A single record in an EPrints Repository. Generally this will be described as BIBO and Dublin Core, and may have a number of associated ep:Documents. Resolving a URI of class ep:EPrint will direct to the HTML summary page for the record, in an HTML browser, or to an RDF (XML or N3) document in an RDF client. The RDF document will contain all available RDF information about the record including all attached ep:Document records and their metadata and links from the document to the files via ep:hasFile. Not all files may be available without authentication. If the files themselves contain semantic information of interest these will need to be resolved separately. References to people, organisations, publications and locations may be given URIs of the form /id//ext- -- in this case the URI will be resolvable as RDF+XML or N3 and may yield additional records in the repository referencing the same thing, although this is usually based on the hashing of metadata strings and may not be complete or perfect. The ext- indicates that this concept is not something the repository actually stores information about, it is just referenced by one or more records. For example, the RDF for an EPrint about a paper given at a conference may reference that conference with a URI of the form /id/event/ext-a43de4454. That URI will be resolvable but the repository does not contain full information about that event, just information derived from EPrint record metadata. It is hoped that the community may develop systems to link such URIs to the more definitive URI for an event, person, location etc.
