One of the things that helped kill the expert system industry was
the (multi-dimensional) cost of extracting knowledge from experts.
Another thing was that an expert group is not usually an internally
consistent body of knowledge. If part of the work building reusable
XML vocabularies for commerce is extracting domain specific
knowledge, then it's going to be tough to realise a return.

I observe that ease of use is ultimately cultural or tribal. Think
about learning languages. Is it easier to learn a language that
uses ideograms or an alphabetic as primitives?
