Yep. The granularity question is undecided. That is why document analysis usually precedes schema definition work. Some might want to create a library of element types that are combined ad hoc into schemas as appropriate. Tricky stuff. Much easier with relational systems because they only have one structure and mapping the base datatypes is simpler, there usually being a limited range of implementations of relational systems in the ecosystem. An ontology can deal with this, I guess, but somehow I see the semantic web as being more useful closer to the human view than the machine view. I realize the hype goes in the opposite direction, but that is what I think. len From: Rick Marshall [mailto:rjm@z...] pretty soon we'll be talking normalisation and data dictionaries again ;) rick ps i thought this was exactly the domain of the semantic web.....
