The DIG interface is incomplete, but it is implemented and deployed (see the oiled and protege editors for some examples). > Can anyone point me to where such deployment issues are being worked > out? Our group raised some of this as a requirement for the Data Access Working Group (DA-WG): http://lists.w3.org/Archives/Public/public-rdf-dawg/2004AprJun/ 0286.html Our reasoner, Pellet, also supporst some of this in a fairly crude, GET oriented sort of way: http://www.mindswap.org/2003/pellet/demo.shtml We are working on a solution based on XPointer that would give you some useful URIs for parts of the ontology. Not a lot of this is trivial, or even straightforward, unless you are really working against something like the XML of a document. Cheers, Bijan Parsia.
