Re: [dxwg] Clarify scope of DCAT - Datasets, Distributions, Services?

Thanks for drafting this proposal, @dr-shorthair .

I have a couple of comments:

1. I'm not sure `dcat:Catalog` should be made a subclass of `dctype:Service`. [Its definition in DCAT 1.0](https://www.w3.org/TR/vocab-dcat/#class-catalog) says "A data catalog is a curated collection of metadata about datasets." So, although it _may_ correspond to a catalogue service (as done in GeoDCAT-AP), it can simply be a "static" collection, a mechanism for grouping datasets based on some criteria. I'm aware of examples of this use - e.g., the list of datasets produced by a project/activity.
2. The proposal seems to imply that a `dcat:Catalog` can include records of "data services" only. I agree this is the case for ISO 19115, but I think we should relax such range constraint to allow any type of services to support other use cases. E.g., in DataCite, a service is not necessarily a data service. Moreover, we have examples in Europe of catalogues of online/offline public services (whose metadata follow the [Core Public Service vocabulary](https://ec.europa.eu/isa2/solutions/common-public-service-vocabulary-application-profile-cpsv-ap_en)).
3. It is not clear to me if the proposal supports the possibility for a `dcat:Catalog` to include metadata records of other `dcat:Catalog`'s - I mean, not as sub-catalogues. This is supported in ISO 19115.
