Re: [dxwg] Add property to link from Distribution -> Dataset (inverse of dcat:distribution)

I also don't see a use case requiring the inverse of `dcat:distribution`,

Based on the DCAT implementations I am aware of, my personal understanding is that `dcat:Distribution` is not considered as an independent entity, and in many cases it is denoted just as blank node. Which implicitly means that two `dcat:Distribution`'s, although intensionally identical (i.e., because they have the same title, access URL, etc.), are nonetheless considered as two different distributions.

This seems possible, looking at the actual semantics of `dcat:Distribution`. E.g., you may have two different `dcat:Dataset`'s having `dcat:Distribution`'s with the same access URL - e.g., because they are pointing to the same download page, or to a service API (SPARQL endpoint, WMS, WFS, etc.). They are not the same distribution. The fact that the access URL is identical does not make them the same distribution.

I'm probably going too far, but this use of `dcat:Distribution` drove me to consider whether a `dcat:Distribution` could actually be interpreted as a reification of the relationship between a `dcat:Dataset` and the actual data (and not a description of the data themselves).
