Unique URIs for File Formats

'http://www.w3.org/ns/formats/Format' is a unique, top-level Class URI for specific file formats. Media types do not uniquely identify file formats (eg, serialization formats for various abstract concepts), because not all specific cases do have distinct media types, instances in this class can be used instead for proper identification.

Although the URI-s themselves refer to non-informational resources (ie, they are abstract identifiers), they can be dereferenced. Dereferencing leads to informational resources in XHTML, RDF/XML, or Turtle equivalents, depending on content negotiation.
