Re: review on the draft model of the Data Usage Vocabulary

Hi João Paulo,

Thank you very much for your review and comments! My comments are below.

I agree with you! In this case, we're gonna have dct:publisher as a
property instead of a class. Maybe, we can also adopt dct:Agent instead of
foaf:Agent to solve the dct:publisher's range problem.

I agree and I think it makes more sense! If dct:publisher is a property,
then I think we should also consider duv:consumer as a property instead of
a class.

I think there is an error in the model and we shouldn't have a relation
between DatasetUsage and Dataset.

Initially, Citation was a kind of Dataset Usage, but we changed and created
a different class. We are still not sure about this relation between
Citation and DatasetUsage. Our initial idea is that you use Citation to
mention/cite that a specific dataset was used. On the other hand,
datasetUsage should give an explanation about how the dataset was used.

ok! We are still thinking about this :)
