[dxwg] Profiles and distributions

davebrowning has just created a new issue for https://github.com/w3c/dxwg:

== Profiles and distributions ==
(Issue created to track comments received on Second PWD of DCAT Recommendation from Clemens Portele - email archived [here](https://lists.w3.org/Archives/Public/public-dxwg-comments/2018Oct/0002.html))

Additional question about the interplay of profile choice and distribution:

Say I have a dataset of buildings and it is made accessible according to two different profiles (e.g. two different XML schemas or two different JSON schemas). The two profiles use different vocabularies and there are differences in the content. However, both representations are sourced from the same data. To me this would be a single dataset. However, this is not that clear in DCAT 1.0 and one could also take the view that these are two different datasets - with separate dataset metadata. At least I know cases where this has been represented as two datasets in catalogs. The new DCAT draft adds language about dataset as "a single conceptual entity" which seems to support the view that there is a single dataset in this case. Could guidance be included in the revision to support more consistent implementations, maybe just an example for such a case?

Assuming this would be consondered one dataset: If both profiles would be served through the same API (or service) and profile negotiation would be used, would this be one distribution (since it is a single API) or two distributions (one per profile, but with the same accessURL)?

Currently you can only specify the media type of a distribution. Considering the work on profiles and profile negotiation in the DXWG wouldn’t it make sense to be able to specify the profile(s) that a distribution supports in DCAT?
