Re: [dxwg] Is one of dcat:accessURL, dcat:accessService and dcat:downloadURL required in a dcat:Distribution? (#1197)

Thanks a lot for the feedback.

Let me try to explain the use case briefly. 
We want data providers of Europeana to describe a dataset with a distribution having a SPARQL endpoint access service. This is all achievable with DCAT2.

The part we are missing from DCAT2  is that the SPARQL endpoint serves more data than the dataset to deliver to Europeana. So providers specify the SPARQL query that will provide the resources that are in the dataset for Europeana. 

To represent this distribution of the dataset, we are considering to use a pattern mostly based on PROV. The pattern is this one:.

![Dataset SPARQL](https://user-images.githubusercontent.com/5079915/71115852-d2aec180-21ca-11ea-853c-a89c64dfdd2a.jpg)


The alternative we though of, was to refer to the AccessService from the prov:Activity and also from the dcat:Distribution. As shown below:

 And thanks again for your support.
