Yes, I'm aware of that work. ODRL is a general purpose rights
expression language that can describe re-use policies. This is similar
to the existing Creative Commons ccRel vocabulary which also captures
the permissions, etc that are described by a licence.

The ODRS vocabulary doesn't attempt to describe licenses themselves.
It's intended more of a way to annotate the relationship between a
dataset and one or more licences. Those licenses could be give a
machine-readable description using ccREL or ODRL. So I think the
vocabularies are compatible.

I've already added an issue to cover describing this relationship a little more.

Looking at the DCAT profile it seems that license type is a category
of license, e.g. public domain, royalties required, etc. To me, this
overlaps with what ccRel and ODRL already cover, but at a more coarse
grained level.

I think for the purposes of the ODRS vocabulary we'll leave the
description of licenses reasonably opaque and defer to other
vocabularies to describe those in more detail. However we do
distinguish between separate licenses that relate to the data and
copyrightable aspects of the dataset.
