-----Original Message----- From: Greg FitzPatrick <gf@medianet.org> >I have downloaded [Protoge-2000], but not yet gotten the chance to try it out.

I downloaded it (the earlier release) too and played with making a calendar schema. It took me some time to get into it. When looking at the first results of my tinkering the first thing I noticed was that any subclass of protogé:Thing was declared to be such. So my file full of my local concepts has a pointer back to stanford as well as pointers back to the RDFS concepts. <rdf:Description rdf:ID="#Calendar"> <rdf:type resource="http://www.w3.org/TR/1999/PR-rdf-schema-19990303#Class"/> <rdfs:subClassOf rdf:resource="http://smi-web.stanford.edu/projects/protege/pr otege-rdf/protege-19992012#Thing"/> <protege:abstractProperty>concrete</protege:abstractProperty> </rdf:Description> (From http://www.w3.org/2000/calendar/clendar.rdfs which is not a serious effort in any way - just a play with protege and full of junk) In fact the fact that from Protogé's point of view something is a subclass of Thing is of course information-free. It should therefore be omitted from the serialization. The sooner we get an RDF property desperateNeeds:equivalent then of course we can start to use the relationship between protege:thing and rdf:resource >Should Protégé be seen as an instrument of renormalization shedding light on >the processes of serializing conceptuality or as the FrontPage of RDF? That all depends on whether it gravitates to a community consensus and a weblike way of working - with community feedback and source code - or whether it is an output-only project! ;-) So far, things are looking good as seen from a gret distance. tim wearing no hat
