Hi Lewis - 

First we are seeking feedback from the community as a whole on the proposed revisions to DCAT. 
The editor's  draft is https://w3c.github.io/dxwg/dcat/ and the particular things that we are seeking comments on are 
(a) the proposed changes as listed in the change-log Annex E ; 
(b) any obvious errors or omissions. 

Bear in mind that DCAT is a general-purpose vocabulary for data catalogs, not specific to research or science. 
And it sits in the context of the W3C suite of RDF vocabularies and ontologies. 
There is a more reference made to some complementary vocabularies such as PROV-O and DQV in this version of DCAT. 
The other main area of innovation in the revision is the addition of DataServices.  

And, as I mentioned below, the catalog and dataset elements in schema.org were drawn more or less directly from an earlier version of DCAT. 

Next there is some interest in whether the extension points available in DCAT for attaching descriptors that are important for research data are sufficient. We are primarily expecting to recommend use of elements from PROV-O for provenance and versioning requirements, and do not expect to be prescriptive on the details otherwise.

Thank you for connecting the dots. Can you point us at the specific material you are looking for feedback on? Discovering the overlaps and reducing the duplication of effort is exactly where the science-on-schema.org (soon to be renamed geosci.schema.org) effort is at.
Thanks

    Karen - science-on-schema.org is based on schema.org. 
    And in turn, the dataset/catalog parts of schema.org were based on DCAT 0.9. 
    So this is no coincidence - see 
    
    https://schema.org/Dataset 
    https://schema.org/distribution etc. 
    
    The close relationship with schema.org was already mentioned and a partial mapping provided in the DCAT-rev draft 
    https://w3c.github.io/dxwg/dcat/#dcat-sdo 
    
    Or perhaps I am missing your point? 
    
    FWIW I tried mapping one of the examples that we've recently been working on into schema.org -
    Compare https://github.com/w3c/dxwg/blob/dcat-issue317-simon/dcat/examples/csiro-stratchart.schema.ttl 
    with https://github.com/w3c/dxwg/blob/dcat-issue317-simon/dcat/examples/csiro-stratchart.ttl 
    It is almost complete, though the schema.org `EntryPoint` model is a little different (more elaborate) than the proposed `dcat:DataService` modeling - see https://github.com/w3c/dxwg/blob/dcat-issue317-simon/dcat/examples/csiro-stratchart.schema.ttl#L42

    
    I think I already contacted the (geo)science guys for feedback on our work, but I've cced them again here in case I missed it.

    They appear to have directly borrowed from DCAT, using "data catalog"
    and "distribution" as DCAT does. It definitely makes sense to ping this group for any comments on DCAT. Andrea, can you do that?
    
    Thanks!
