It's great to see that some work is finally being dedicated to this very important Semantic Web effort. I figured that before suggesting how to move forward, I'd take stock of what we have already. First, the DCES 1.1 spec contains an RDF Schema embedded in the HTML: http://purl.org/dc/documents/rec-dces-19990702.htm Unfortunately, it uses a pre-release namespace for RDF Schema, thus making it unreadable by most RDF apps. However, it doesn't seem like it is at all outdated, so chaning the namespace should repair this problem. However, it seems odd to me that no DC document mentions this definition, nor is it available in a way easily parsable by RDF processors (it's not in an XML document). An easy thing to do would be to write up a short document with the RDF schema and explaining its use in generic RDF. Second, there is a proposal for guidelines on using DC in RDF: http://www.ukoln.ac.uk/metadata/resources/dc/datamodel/WD-dc-rdf/ While this is a very good start, it's already outdated and has a number of problems that should be fixed before being recommended by DC. Unfortunately, this is really the only doc out there that gives suggestions on using DC in RDF, and thus is the one everyone points to (and uses). I disagree with a number of the examples, and also think that the qualification/type system is outdated since RDF Schema. Third, there is a description of DCES XML files: http://purl.org/dc/documents/wd/dcmes-xml-20000714.htm While this is a wonderful system for simple DC XML files, and it's even better that they use RDF, this is (as the document clearly admits) a very limiting system. These are all the documents I could find -- if you know of any more, please email me.
