I'm very excited to see Norm Walsh's post about Topic Maps today!
I've been trying to get Topic Maps adopted in our Services organization for several years, but RDF/OWL seem to be the heavy hitters so far.
I think Topic Maps are extremely valuable, and offer a number of advantages over RDF. (see my previous post)And it's an ISO standard to boot! (ISO/IEC 13250). Now that Norm is experimenting with them, perhaps topic maps can get more traction at Sun.
Murray Altheim has also been a big proponent of topic maps, but ran into a lot of the same hurdles I have.
If anyone else at Sun has experimented with Topic Maps, or would like to learn more, please contact me!
