Hi Stan,

This is more about the decision process than the group itself. It is also in
reference to using the DarwinCore for the semantic web.

Roger Hyam and others have stated that we need some set of use cases and
test data that people can try.

I think the merits and potential problems of various approaches will be much
clearer when there is a set of use cases and a test data set.

In other words, people should demonstrate and support their arguments with
real examples.

The alternative is an unending series of debates.

As I said before, the DarwinCore is fine for what is is being used for.

What I am not seeing are real examples of it being used successfully on the
semantic web.

 Good examples would include demonstrations of useful SPARQL queries on a
DarwinCore data set.

The proof will be in the pudding, either it will work fine and do everything
people expect or it will not.

The motivation could that those arguments that are not supported by examples
lack credibility.


- Pete
