DaveBrowning: So, it's just 3 of us. What we want to talk about?
20:13:59 [AndreaPerego]
SimonCox: [explaining the PRs created in the last days]
20:14:36 [AndreaPerego]
... some of them are pretty trivial / editorial.
20:15:13 [AndreaPerego]
... The substantial one is https://github.com/w3c/dxwg/pull/909
20:15:23 [AndreaPerego]
... about spatial / temporal encoding.
20:16:11 [AndreaPerego]
... I think addressing it is useful, also because the geo community didn't address it.
20:17:13 [AndreaPerego]
... For the temporal, AndreaPerego added a DCAT-based solution. I added here an option based on existing vocabularies, in particular OWL-Time.
20:17:48 [AndreaPerego]
DaveBrowning: Those different approaches, do we need them? Which is the requirement behind it?
20:19:13 [AndreaPerego]
SimonCox: So, e.g., for another temporal-related issue - temporal resolution - we eventually opted for a DCAT-specific solution, simpler than using existing vocabularies as RDF DataCube.
20:20:21 [AndreaPerego]
... AndreaPerego took a similar approach to spatial / temporal coverage, using DCMI. The issue is that neither DCMI nor DCAT 2014 explained how to do that in practice.
20:21:45 [AndreaPerego]
... AndreaPerego, are we using the spatial-related properties only for datasets?
20:22:12 [AndreaPerego]
AndreaPerego: I think yes, but in theory they can be used on any dcat:Resource with a spatial coverage.
20:23:31 [AndreaPerego]
SimonCox: About the temporal coverage, the addition of OWL-Time is actually an alternative way of doing what can be done with dct:PeriodOfTime.
20:25:41 [SimonCox]
... and can support non-Gregorian calendar requirements
20:26:50 [AndreaPerego]
... So, the issue about alternatives is to clarify how they fit different requirements.
20:27:56 [AndreaPerego]
AndreaPerego: Yes, I think this can simply done with a short explanation saying what you can do with each option (e.g., only WGS84 vs any CRS).

ANd for Spatial, the WKT options allow fir different CRS, while the w3cgeo soluion is fixed to WGS84

20:30:38 [AndreaPerego]
AndreaPerego: Just to mention that the proposed solutions for spatial / temporal coverage are those adopted in DCAT-AP, and addressing gaps identified in that context.

20:33:02 [AndreaPerego]
DaveBrowning: I would be in favour of having this included, as spatial / temporal is not something domain-specific.

20:35:42 [AndreaPerego]
SimonCox: AndreaPerego, I'm a bit nervous with using LOCN, because of its adoption limited to Europe.
20:36:39 [AndreaPerego]
AndreaPerego: Actually, in the originally issue, I was proposing some alternatives, one of them being the definition of a property dcat:geometry, equivalent to locn:geometry.
20:36:50 [AndreaPerego]
SimonCox: This can indeed be another option.
20:37:29 [DaveBrowning]
q?
20:37:48 [SimonCox]
need an example with a CRS

All: [some discussion of geometry encoding, CRS, et similia]
20:43:50 [AndreaPerego]
DaveBrowning: Coming to the status of DCAT, I think we are very close to the final version. So, the question is what we want to bring up in the next meeting as critical.

AndreaPerego: One of them is whether we want to keep or move out the alignment with LDP.
20:47:47 [AndreaPerego]
DaveBrowning: We need to finish that conversation.

DaveBrowning: About what is yet to be done, we need to check the links. But are there other editorial issues to be addressed?
20:56:17 [AndreaPerego]
... I'll put an early agenda for next week, to check if we have finished or not.
20:56:48 [AndreaPerego]
... So, if the answer is yes we can go the plenary for approval.
