Hi all, 

A few more comments: 

duv:refersTo defines that the resource O in a triple "S duv:refesTo O"
is a dcat:Dataset and a dcat:Distribution. 

duv:hasUserFeedback defines that the resource S in a triple "S
duv:hasUserFeedback O" is a dcat:Dataset and a dcat:Distribution. 

duv:hasUsage defines that the resource S in a triple "S duv:hasUsage O"
is a dcat:Dataset and a dcat:Distribution. 

The domain of duv:hasUsageTool is duv:Usage. 

The property duv:classification (in the diagram) between DataCitation
and Agent does not exist.. 

The diagram has double-ended arrows that could induce someone to think
that the two properties are inverses. I think it is better two have the
two arrows. 

Maybe it will be necessary to define the disjoint classes of duv. 

Thank you. 

Cheers, Laufer

If you want to add a domain and range, then, OK, as has been said - define sub properties, but you can do it less formally by adding a usage note (vann:usageNote). That can be free text that says "when used in this context, ex:foo is used in this way" Again, DCAT provides examples of this.
