[Dan Brickley] FWIW, I've rigged the namespace http://xmlns.com/wordnet/1.6/ to return chunks of the wordnet noun hierarchy projected into RDF classes. deferencing http://xmlns.com/wordnet/1.6/Tree or .../Car or .../Person gets a fragment of the larger (much larger) ontology. Don't look too closely, the generated markup has bugs, but the scenario should at least be reasonably clear. It gets the superclasses and subclasses of Tree, right? Starting with Yellowwood, and ending with "Tree_of_Knowledge" (a rare species not seen since Genesis). I don't claim this provides a 'natural definition', but it does seem more useful than having the entire multi-megabyte wordnet RDF thing be downloadable at the schema namespace URI. I am not too familiar with Wordnet, but it doesn't seem to provide much more than a subclass hierarchy + synonym links (?) + comments. I agree that there is a natural definition of "subgraph pointed to" for a subclass hierarchy (namely, the subclasses and superclasses of the nodes you start with). As soon as you put anything else in, the definition breaks down. If someone wants to use "#Dog" and "#Tree" from an ontology, they want to know more than, say, are there more breeds of dog or species of tree (as far as this system believes)? -- Drew McDermott
