In the last meeting the group voted for the publication of the FPWD of DUV.
I suggest to correct some of the minor mistakes that you found and to
include the major changes as issues in the document. I already created new
issues for this.

I'm sorry, but I don't understand your proposal. Could you please give an
example?

ok!

This is a good question. A issues was created for this:

The idea is to show that the usage of a dataset usage may result in the
generation of a new dataset, but i think this is not clear.

It's true! we're gonna correct this.

duv:endorses is a subproperty of oa:has_target.
oa:hasBody has a different meaning from duv:hasRating and they should be
treated differently.

it sounds good!

ok!

Later on examples will be rewritten according to the updates that will be
