20:13:11 <AndreaPerego> scribenick: AndreaPerego
20:13:39 <AndreaPerego> 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).
20:28:01 <AndreaPerego> q+
20:28:12 <DaveBrowning> ack AndreaPerego
20:28:19 <DaveBrowning> q+
20:29:57 <SimonCox> ANd for Spatial, the WKT options allow fir different CRS, while the w3cgeo soluion is fixed to WGS84
20:29:58 <DaveBrowning> ack DaveBrowning
20:30:06 <SimonCox> s/fir/for/
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.
20:34:04 <AndreaPerego> q+
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
20:38:04 <DaveBrowning> ack AndreaPerego
20:42:41 <AndreaPerego> 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.
20:44:17 <AndreaPerego> q+
20:44:47 <DaveBrowning> ack AndreaPerego
20:47:32 <AndreaPerego> 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.

20:55:28 <AndreaPerego> 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.
20:57:14 <AndreaPerego> +1 from me
