Hey Doug –

Note that dcat:Dataservice is intended to be a ‘minimum viable’ approach, delegating all the details to values of the `dct:conformsTo` and `dcat:endpointDescription` properties, which SHOULD use external standards. See https://w3c.github.io/dxwg/dcat/#ex-access-service and https://w3c.github.io/dxwg/dcat/#data-service-examples and the third example here https://rawgit.com/w3c/dxwg/dcat-issue317-simon/dcat/index.html#bag-of-files (on a branch that will likely be merged into gh-pages shortly). The last one is mirrored by an attempt I made to translate it into schema.org – see https://github.com/w3c/dxwg/blob/dcat-issue317-simon/dcat/examples/csiro-stratchart.schema.ttl (on the branch again). I struggled a bit to interpret how to use schema:EntryPoint and may have got it ‘wrong’ at line 42 etc.

  Thanks for the ping..  As Adam, mentioned he and I got funding from NSF/EarthCube for follow on work and should be starting around the time RDA P13 takes place.   So we actually have some funding to do some of this work.   I'll get that geologic time stuff in for the scientific drilling!!!  I've owed you that for TOOOOOO long.
We want to do the vocabulary stuff inside ESIP to make sure we have a broader geoscience audience than just Adam and I.  😊    Hat tip to Adam for doing that and to Lewis for fostering the momentum at ESIP.

  One of the other items Adam and I talked about at ESIP Winter meeting was as the dcat:DataService.   I'm keen to review that in more detail with regard to it's mapping to schema.org.   I put a simple image at http://labs.geodex.org/pres/01.html#slide3 that we used to talk about this with some of the people at ESIP.   We are working with IRIS and UNAVCO,  both who deal more with streaming data and we are interested in how we can better represent that data.  The full set of groups involved with us is at http://geodex.org/about.html .

  Adam and I will be at RDA in April and we have been following bioschemas.org but never had the chance to really interact with them.   Not for lack of interest!   Sadly more lack of time.   However, it would be good for us to focus on communicating and exchanging experience with them.   Also, we have been involved with the Data Discovery Paradigms IG in RDA.  Mostly though talking and interacting with Mingfang.

  I quickly read through section E much of this resonates with me based on the experience we got harvesting the NSF providers and building a test graph and UI at https://geodex.org/  (lot's of UI bugs there.  a test for sure that needs some attention in this next phase).     The experience of dealing with the material provided by so many really highlighted some approaches and procedure changes we need to incorporate into this next round of work.

Thanks..  fun and exciting..
Perhaps there would be some opportunity at RDA to meet and discuss this more?

Take care

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.

    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/distribution etc.

    The close relationship with schema.org was already mentioned and a partial mapping provided in the DCAT-rev draft

    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?
