I think it is useful in relation to data, and the Force11 CodeMeta is mapping to schema, so I'll try for another crosswalk and I think we should add the properties they have compiles 21:15:43 ... Same in the main as codata 21:15:48 +1 to alejandra 21:15:59 +1 21:15:59 s/codata/codemeta 21:16:30 PWinstanley: we can add that to github and bring it into discussion in later meetings 21:16:38 RRSAgent, draft minutes v2 21:16:38 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html DaveBr 21:17:01 topic: range of locn:geometry 21:17:05 RRSAgent, draft minutes v2 21:17:05 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html AndreaPerego 21:17:14 q+ 21:17:23 AndreaPerego: 21:17:23 present+ 21:19:28 AndreaPerego: this is an erratum. Feedback pointing out the inappropriate range (literal) rather than a class. literal was added because of bounding boxes and centroids, but the change will not break anything as locn:Geometry is an abstract class that allows most/all geospatial entities. The property helps specify any place, so flexibility is really needed 21:19:57 ... If we put it in as an error then it is in the erratum page 21:20:52 +q 21:21:04 ack AndreaPerego 21:21:16 ack alejandra 21:21:53 alejandra: the comment by Simon about the Range - is there an issue? 21:22:08 AndreaPerego: here is the relevant bit... 21:22:19 Definition of locn:geometry: https://www.w3.org/ns/locn#locn:geometry 21:22:58 ... the usage note shows it can be encoded as a literal or anything else - it's an abstract class, a placeholder 21:23:16 ... so there is no restriction in the way that geometry can be represented 21:23:31 Topic: Versioning 21:23:55 q+ 21:24:00 ack AndreaPerego 21:24:20 RRSAgent, draft minutes v2 21:24:20 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html DaveBr 21:24:57 AndreaPerego: one point is discussion about currentVersion and lastVersion - what they mean and how relevant they might be 21:26:38 ... the prop :currentVersion is meant to point to a snapshot that represents the 'current' version. This prop should be used when versions of a resource are available and published sequentially - to indicate the current version. the other usage is with version chains where there are different snapshots 21:28:03 ... when there is a URI that always points to the 'latest' version, and when there are resources evolving over time, :currentVersion points to the snapshot that is the current one of the moment 21:28:16 https://raw.githack.com/w3c/dxwg/dcat-versioning-v2/dcat/index.html#dataset-versions 21:28:34 ... There are diagrams in the draft document to help explain this 21:29:11 https://raw.githack.com/w3c/dxwg/dcat-versioning-v2/dcat/index.html#fig-version-chain-and-hierarchy 21:32:26 +q 21:32:28 during the meeting AndreaPerego presented the diagram and how it illustrated the rationale for the property 21:32:33 ack alejandra 21:33:09 alejandra: what properties are not in PAV? 21:33:37 What is not included in PAV is dcat:isVersionOf and dcat:hasLastVersion. 21:33:59 q+ 21:35:37 ack Makx 21:36:39 Makx: I have difficulty understanding why we are doing this. the explanation works on the basis of document versions, but I don't see the dataset case here because the URIs are not for datasets but are for duplicates of the same thing 21:36:48 +q 21:38:04 ... I would think that all we need (in the diagram) it pointers for the dcat2 - dcat3. With datasets it's just a duplicate identifier for the same dataset 21:38:47 ... I think it would be easier to understand with :previousVersion and :nextVersion links 21:39:09 ... I don't think :lastVersion is necessary 21:39:12 Example of dataset: https://raw.githack.com/w3c/dxwg/dcat-versioning-v2/dcat/index.html#ex-version-chain-and-hierarchy 21:39:27 AndreaPerego: we have an example of a dataset - see link 21:39:37 ... this is taken from DWBP 21:39:51 ... a dataset and different snapshots of the same dataset 21:40:29 ... In the versioning section we discuss, but we are not requiring - it is providing options that you have available 21:42:00 Makx: My recommendationis to stay to what PAV has and just have a link to the previous version 21:42:04 ack alejandra 21:42:15 https://www.w3.org/TR/hcls-dataset/#datasetdescriptionlevels 21:43:21 alejandra: in the link for HCLS there is a reliance on PAV. I liked the figures shown earlier, but I think that because it focuses on a document example it missed some of the points that we might use if the example was relating to datasets 21:43:37 ... in the HCLS we relied exclusively on PAV terms 21:43:52 ... The other q relates to :isVersionOf 21:44:05 ... do we need dcat, or could we use dct: 21:44:40 AndreaPerego: the reason we rely on PAV is that there is a more specific sense of version comparing than with dct. 21:46:02 alejandra: the only one I had doubts about was :isVersionOf 21:46:25 AndreaPerego: we are relying exactly on the PAV data model - 21:47:00 +q 21:47:01 ... the alternative is not to use the full PAV model 21:48:13 ... the examples (I agree with alejandra and Makx that a dataset example would be good and I've started to add one). 21:48:16 ack alejandra 21:48:42 RRSAgent, draft minutes v2 21:48:42 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html DaveBr 21:49:06 alejandra: I agree that semantically it would be enough to have a chain of versions, but is it worth considering query performance and the computation of long property chains? 21:50:21 AndreaPerego: when creating a new version, are you going to alter the record of the previous dataset? This is really a metadata management decision. 21:50:45 +q 21:51:24 ... It can be done, but depends on policies etc for metadata management. We can mention these, but I wouldn't provide recommendations - this is an implementation issue 21:51:40 ... also people can just pick up and use what they find useful 21:52:23 ... Having use cases to work to would be helpful. This is just a draft for discussion, and needs testing 21:53:10 ack alejandra 21:53:55 alejandra: thanks for the clarification. Situations where the rights to modification don't exist point to having this arrangement of props 21:54:39 q+ 21:55:05 ADMS F/OSS: https://joinup.ec.europa.eu/sites/default/files/documentation/ADMS.FOSS_specification_v0.01.pdf 21:55:07 ack AndreaPerego 21:55:44 AndreaPerego: referring to the point about software raised earlier by alejandra , F/OSS might be a good starting point 21:55:48 ... see link 21:57:53 rrsagent, create minutes v2 21:57:53 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html PWinstanley 21:59:26 AndreaPerego: there is a PR #927 which is a contribution relating to a Romanian translation 21:59:44 AndreaPerego_ has joined #dxwgdcat 21:59:55 +q 22:00:04 ... this is parked and needs to be decided on - do we want to get an update from them 22:00:09 ack alejandra 22:00:26 alejandra: can we include a partial translation? it is better than nothing 22:00:39 +1 22:00:59 RRSAgent, draft minutes v2 22:00:59 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html AndreaPerego_ 22:01:05 rrsagent, create minutes v2 22:01:05 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html PWinstanley 22:02:18 thanks, and bye! 22:02:33 bye 22:02:38 bye 22:02:43 rrsagent, create minutes v2 22:02:43 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html PWinstanley 22:02:58 RRSAgent, draft minutes v2 22:02:58 I have made the request to generate https://www.w3.org/2021/03/03-dxwgdcat-minutes.html AndreaPerego_
