riccardoAlbertoni: Any changes to the agenda?
<SimonCox> no changes
Examples of a manifest for DCAT2 (https://github.com/w3c/dxwg/issues/1243)
Examples of a manifest for DCAT2
riccardoAlbertoni: the interest here is specifically relating to many files and their aggregation
… looking at the European Data Portal there are some examples, but are there any others/
<riccardoAlbertoni> https://www.europeandataportal.eu/data/datasets/593c5b46-5c92-475e-90fa-20077fc3c06e?locale=it
<SimonCox> https://www.w3.org/TR/vocab-dcat-2/#examples-bag-of-files
<SimonCox> but I suspect that dcterms:hasPart might be better
riccardoAlbertoni: even if it is not in the manifest, using the DCAT example of a bag of files will be helpful
SimonCox: I did this work a long time ago - we used the dct:relation to point to the components, but on reflection using dct:hasPart might be better.
… because relations have no semantics and it could be a seeAlso etc, but the specific case here is saying that the set of artefacts together represent the catalogues assets, but we can also use in the context of elements of a dataset
… this might mean moving dct:hasPart to a property of dcat:Resource
<SimonCox> ... or maybe on dcat:Dataset
riccardoAlbertoni: so we are pointing to some kind of answer, but what if there are files in different directories etc, where do we point to then?
SimonCox: relative paths can be used in the URI, not 'linked data' friendly, but appropriate semantics
riccardoAlbertoni: I think that both of these examples will be helpful
SimonCox: an improvement of the spec would be to make it explicit that dct:hasPart can be used in a dataset description
<SimonCox> i.e. `dcterms:hasPart` is recommended for use on `dcat:Dataset` (promote from `dcat:Catalog`)
riccardoAlbertoni: I think we should provide examples, but not change the recommendation
<SimonCox> This is also relevant https://www.w3.org/TR/vocab-dcat-2/#qualified-relationship
Action: riccardoAlbertoni to update examples and add notes to github issue 1243

Service Descriptions
riccardoAlbertoni: is there any objection to clustering these 3 issues in the same milestone?
PWinstanley: the first (cataloguing the SQL database data) seems different to the other two, which are about an entry point to accessing data
riccardoAlbertoni: they all ask for more information about data services - they want to take data from a service, and the pointer is providing more than one dataset so the type of direction to get the query targetting a specific dataset is required
… Andrea has already suggested some response. I think that this is out of the scope of DCAT
AndreaPerego: in the last plenary I outlined the issue
… DCAT is generally about describing material that is available on the web, whereas the enquiry was about things which are more likely to be enterprise data
<riccardoAlbertoni> ack
AndreaPerego: I also got the impression that the requirement is somehow related to the data service part (API etc) and this is where our use cases ended
AndreaPerego: extensions that suit enterprise use are generally specific to the enterprise.
… so I'm not sure if this is generalisable
PWinstanley: are the requirements of gov getting more sophisticated?
SimonCox: maybe. There are also internal enthusiasts who are looking to bring semantic tech into their cataloging efforts
riccardoAlbertoni: A reply might include some guidance on extending DCAT via the dcat:DataService with things like ODBC connection and example queries
AndreaPerego: unless we are going to get more enquiries about the same topic we should just provide some guidance, which can include examples of how to express queries etc
AndreaPerego: a comment about the manifest: one of the things I was thinking is that we could ask for use cases, because the manifest file can mean a simple list or more sophisticated information that can assist with e.g. visualising the archived data
