I would suggest that the RDF WG look at Part 3 "Determining Resource Identity" of "Resource Identity and Semantic Extensions: Making Sense of Ambiguity": http://dbooth.org/2010/ambiguity/paper.html#part3 That section proposes a standard process for determining resource identity. As far as I know, I did not invent this process. I simply documented what seemed to be the general ideas floating around. However, I did identify one specific gap in the RDF specs: [[ At present there is a minor gap in the RDF standards, in that there is no standard way for an RDF processor to recognize that a particular URI is intended to signal an opaque semantic extension: the knowledge of which URIs are intended to signal opaque semantic extensions must be externally supplied to the RDF processor. The RDF processor must magically know about them in advance. It cannot alert the user to the need for a new opaque semantic extension that was previously unknown. This gap could be addressed by defining a standard predicate, such as rdf2:requires, to explicitly indicate when a particular semantic extension is required. However, since it currently seems unlikely that many semantic extensions will be needed that cannot be defined using standard inference rules, this does not seem like a major gap. ]] I will forward this message separately to the RDF comments list, since I cannot post to the regular RDF list. -- David Booth, Ph.D. http://dbooth.org/ Opinions expressed herein are those of the author and do not necessarily reflect those of his employer.
