Ed,

In my mind, there is nothing that would prevent people to use DCAT for a
collection of unrelated data, and I don't think we want to tell them
they can't. Also, it would depend on someone's perspective on what
constitutes 'related'.

Again, my position is that the definition of dataset in DCAT is good
enough, and that we should not spend time in trying to make it better.
