An Ontology for Relating Generic and Specific Information Resources This ontology implements concepts discussed in the Generic URIs 'DesignIsues' note. It is also the topic of the W3C TAG issue and a related TAG finding. This ontology does not model the fact that representations of a resource can be customised as a function of things like user agent, target media, the geographical position of the user, the preferences of the user, etc. These could be and can be added. The FixedResource class is defined to be specific to ANY variation, as is the fixedResource property. $Id: ont.rdf,v 1.7 2009/04/20 10:12:30 timbl Exp $ A resource which may have representations in many different Content-Types. A resource of which all representations are in the same Internet media type, or 'Content-Type'. A resource whose representation type and content will not change under any circumstances. An Information Resource is defined by the Architecture of the WWW. A resource defiend without constraint as to the particular natural language in which it maight be expressed. A resource of which all representations are in the same natural language. A Information Resource which may have many versions, and therfore representations of the resource at different times may vary. A resource of which all representations are in the same version. Representations of the resource will not change as a result of th resource neing updated to a version with time. The dates of creation and of last modification of such a resource would be expected to be the same. A relation between a generic resource and a fixedResource which is an everything-specific version of it. The equivalence relation linking all versions of a work, specific or generic along various axes. The related resource which for this time-sepcific resource is the related time-generic resource. A representation of the time-generic resource may be expected to be the most recent time-specific resource at the time of the representation.
