Extra Types Namespace

This namespace provides identifiers for many common formats and encodings, and also for documents in that format and for (RDF) literals containing fragments of these formats. The Format-XXX and Encoding-XXX classes are intended for use with dcterms:format or similar predicates. The Document-XXX and DocumentEncoded-XXX classes are intended for use with rdf:type to indicate the format and character encoding of the Document available at a URL. The Fragment-XXX classes are intended for use as the datatype of literals in RDF.
