I find UML useful and accessible but a bit of a pain to use. I used Booch's modelling when it was first published and have had a long history with OO design. It didn't come easy at first, but now seems natural. I think that OO development and the related modelling takes a bit of getting used to, but there's certainly a fair percentage of the developer population for which it works. Don't know if those people are ordinary, but they seem mortal enough... > In any case, people who are already conversant in UML should find OWL > not so intimidating. I don't find it intimidating, just a whole lot of writing. The ability to produce it using graphical modelling tools would definitely make it far more approachable and I believe there are people (companies?) doing this? Haven't need to look yet. <snip>discussion on Ontology building approaches and bottom up/top down discussion</snip> > I've said this before, but I personally believe that some way to > combine the two is the key. Makes sense. Certainly the vertical industries and the government will produce top down approaches. Left on their own I think it would be a very long time before these ever find enough intersection to branch out and meld into something globally traversable. Search driven approaches do seem to allow that gap to become almost irrelevant for most humans, but that still leaves the automated machine driven discovery dangling. Bottom up thin horizontal layers like FOAF seem like ideal candidates to branch out and form a basis for connecting some of the dispersed vertical domains, in particular if you imagine FOAF (or variants) being used to build informal linkages between things that aren't people (which is already happening): then you get people describing informal networks of relationships in machine readable form. Having the average Joe being able to annotate their personal Web pages with "things I Like" and "things I trust" as well as "people I know" could have a huge network effect, in particular when some of the things they like or trust turn out to be Ontologies (implicitly or explicitly). -- Peter Hunsberger
