Thank you for your burst of cold reality in this increasingly abstract discussion. In debating the structure of UCD2, I have been continually thinking of you and others who build actual software that "understands" UCD.

Unfortunately, I cannot answer your questions. I could simply say there will be a web service for doing the matching, but then you will say who and where and when. I do not know. Can I call here fo volunteers to make the UCD2 services? How soon?

I am beginning to think that adopting UCD2 will require a lot of hard work by a lot of people -- data providers as well as consumers -- and I am not seeing the concrete and immediate benefits.

Perhaps we should start working towards a very sophisticated RDF-based model ("UCD3") for alpha release in a year or two. But stay with a cleaned-up UCD1 for the near to medium term.

Comments anyone?
