Thoughts? /Roger I don't know that I quite buy into this bit of "two is all there is" for xml, but letting that go for the moment, you have rdf - 1) Two bulding blocks, resources and literals. 1) One means of assembly, the triple (or the predicate,if you prefer). Trouble is, rdf isn't up to everything in the way of knowledge representation - like you can't make statements about specific rdf subgraphs. I am a great believer in simplicity, but often, you have to use the simple atoms in definite an repeatable structure, like molecules. Then it can be much easier to work with the molecules instead of the atoms. Topic maps has some molecule machinery, rdf does not. Cheers, Tom P -- Thomas B.
