21:13:57 <riccardoAlbertoni_> topic: Dataset Series
21:14:14 <alejandra> riccardoAlbertoni_: we prepared some material about dataset series
21:14:54 <riccardoAlbertoni_> https://github.com/w3c/dxwg/wiki/Examples-on-dataset-series,
21:14:58 <AndreaPerego> Draft section in ED: https://raw.githack.com/w3c/dxwg/dcat-dataset-series/dcat/index.html#dataset-series
21:15:30 <alejandra> riccardoAlbertoni_: I'd like to start discussing the PR prepared by Andrea
21:16:15 <alejandra> AndreaPerego: put together what it was discussed so far, trying to structure some consistent ideas on how to specify dataset series
21:16:25 <alejandra> ... I organised the section in introductory and two subsections
21:16:41 <alejandra> ... notion of dataset series, same issue as with versions
21:16:54 <alejandra> ... it is community specific, and the term is not used consistent
21:17:25 <alejandra> ... in stats domain it is formally define in a very strict way
21:17:33 <alejandra> ... set of dimensions where the values are always the same
21:17:51 <alejandra> s/consistent/consistently
21:18:05 <alejandra> .. in other cases it is not so strict
21:18:30 <alejandra> ... group according to space or temporal dimensions and you may need to include some additional information as part of the dataset that is part of the series
21:18:54 <alejandra> ... it is a very heterogenous situation so we are not trying to define dataset series but to explain how to represent them using DCAT
21:19:04 <alejandra> ... considered use cases that we got from people
21:19:19 <alejandra> ... consesus of using dct:isPartOf dct:hasPart
21:19:28 <alejandra> s/consesus/consensus
21:19:51 <alejandra> ... datasets released on a yearly version, using what we did for versioning section
21:20:51 <alejandra> ... last section on some discussion not developed completely
21:21:16 <alejandra> ... dataset with some characteristics, spatial / temporal coverage, spatial / temporal resolution
21:21:27 <alejandra> ... how this should be reflected in the metadata describing the series
21:21:37 <alejandra> ... discussion about this topic and idea of inheritance principle
21:21:48 <alejandra> ... child dataset should inherit what it was defined at the series level
21:22:17 <alejandra> ... upstream inheritance might make more sense
21:22:59 <alejandra> ... reason is that dataset series with data from different years, the temporal coverage for each dataset is a specific year, but the series year is all the years of the series
21:23:10 <alejandra> ... similarly with spatial coverage
21:23:17 <alejandra> ... also temporal / spatial resolution
21:23:48 <alejandra> ... how to deal with annotation properties related to the publication process
21:23:54 <PWinstanley> q+
21:23:58 <alejandra> ... what should be the last update date, update frequency
21:24:12 <alejandra> ... these aspects are addressed on the last part of the proposal
21:25:05 <alejandra> ... the idea is that the creation date of the series should be when the first child dataset has been created, earliest date
21:25:38 <alejandra> ... when talking about last update, the series will have the date of the last child
21:26:16 <alejandra> AndreaPerego: final point is about update frequency, the proposal is that it should correspond to the most frequently updated child dataset
21:26:28 <alejandra> ... the proposal was a way to raise these issues for discussion
21:26:39 <riccardoAlbertoni_> q?
21:27:26 <riccardoAlbertoni_> ack PWinstanley
21:27:38 <alejandra> PWinstanley: all of what you said makes sense
21:28:00 <alejandra> ... when using dcat:Distribution, can we have distribution of distributions
21:28:20 <AndreaPerego> q+
21:28:23 <alejandra> ... I wonder if we should have somethingt hat specifically characterises datasets that are series
21:28:54 <riccardoAlbertoni_> ack AndreaPerego
21:28:59 <alejandra> ... we've included hasPart but there might be a situation when we created a dataset and the hasPart has not been minted yet but we know it is going to be a series
21:29:13 <riccardoAlbertoni_> +q
21:29:23 <alejandra> AndreaPerego: about the last point, I forgot to mention that we are discussing if we should create a new type or use a soft type approach
21:29:42 <alejandra> ... for the time being, while we discuss it, I used the soft typing approach
21:30:58 <alejandra> AndreaPerego: for the distribution, practical issues
21:31:02 <alejandra> ... the way people are using it
21:31:16 <alejandra> ... most frequently catalogue patterns are not supporting the notion of dataset series
21:31:49 <alejandra> PWinstanley: if I have a budget dataset and I have distributions (csv, and other format), those are distributions
21:32:18 <alejandra> ... having it in there, acknowledges them
21:32:56 <alejandra> AndreaPerego: we have an example by Jakub about many datasets
21:33:10 <alejandra> ... other examples for geospatial data from the INSPIRE infrastructure
21:33:18 <alejandra> ... each satellite image as a dataset
21:33:26 <alejandra> ... many datasets for one series
21:33:42 <alejandra> ... in the geospatial domain, people are creating series and not creating the children dataset records
21:33:49 <alejandra> PWinstanley: use data cube for this
21:33:58 <alejandra> AndreaPerego: yes, but this is on the data management side of things
21:34:07 <alejandra> PWinstanley: as a cube, it could be slices of information
21:34:30 <alejandra> AndreaPerego: for me, the uses cases that were contributed shouldn't be dealt with at the catalogue level
21:34:44 <alejandra> ... postal information, one of the post complex data models in INSPIRE
21:34:51 <alejandra> ... complex in terms of representation
21:35:06 <alejandra> ... have a landing page where you can filter based on the criteria the slice that you want on the dataset
21:35:19 <alejandra> ... in these cases, I don't see how it can be managed effectively
21:35:34 <alejandra> PWinstanley: service that delivers the distribution, but its metadata is going to be fairly generic
21:35:51 <alejandra> AndreaPerego: something else - the section is focusing on the approach that a series is itself a dataset
21:36:16 <alejandra> ... paragraph mentioning that people are using distributions, but we propose as a default approach creating a dataset for child dataset
21:36:36 <alejandra> .. in case where the distribution approach is more suited, we don't restrict it
21:36:55 <riccardoAlbertoni_> q?
21:36:58 <alejandra> ... this is the request that we got, consistent way of doing this if people want to do it
21:37:05 <riccardoAlbertoni_> ack riccardoAlbertoni_
21:37:25 <alejandra> riccardoAlbertoni_: as far as I am concern, this is a set forward, some issues that need to be discussed still
21:37:36 <alejandra> .. we can try to highlight the open issues in the document
21:37:36 <riccardoAlbertoni_> https://github.com/w3c/dxwg/wiki/Examples-on-dataset-series
21:37:50 <alejandra> ... some of Peter's observations are mentioned as aspects in the wiki page
21:38:04 <alejandra> ... at the end, there are different examples in the spirit that Andrea explained
21:38:16 <alejandra> ... at the end there is a discussion section, where different aspects are listed
21:38:39 <alejandra> ... one aspect about using dataset or distribution, already expressed my concerns about using distribution
21:38:49 <alejandra> ... but at the moment, mentioning both is the best approach
21:38:58 <alejandra> ... what can we do next?
21:39:09 <alejandra> ... one question for Andrea - what is missing to accept the draft PR?
21:40:22 <AndreaPerego> q+
21:40:32 <alejandra> riccardoAlbertoni_: we are expecting to have the first PWD at the end of November
21:40:43 <alejandra> ... there will be issues we won't be able to resolve
21:40:49 <alejandra> ... but important to show the discussions
21:41:10 <alejandra> ... for example, the note about the upstream inheritance could deserve an issue
21:41:15 <alejandra> +1 for creating an issue on that
21:41:30 <alejandra> riccardoAlbertoni_: we have time to do some refinements on this proposal
21:41:39 <alejandra> ... if we include what we have already is a good start
21:41:39 <AndreaPerego> q?
21:41:47 <riccardoAlbertoni_> ack AndreaPerego
21:42:09 <alejandra> AndreaPerego: fine with that, final version on this section and the versioning section by the end of the Month
21:42:21 <alejandra> ... worth including in the PWD
21:42:33 <alejandra> ... having a draft version is not so dangerous
21:42:41 <alejandra> +q
21:43:00 <alejandra> ... based on what has happened so far, it is the only way to have it in a PWD
21:43:16 <riccardoAlbertoni_> ack alejandra
21:43:29 <AndreaPerego> scribenick: AndreaPerego
21:43:36 <alejandra> ... fixing all the points, trying to get an agreement and get it out
21:44:10 <AndreaPerego> alejandra: It would be good to have it in the FPWD.
21:44:22 <AndreaPerego> ... I also agree to create issues for specific aspects.
21:44:58 <AndreaPerego> ... My question is about the not so many meetings we have before FPWD.
21:46:28 <alejandra> PROPOSED: draft on dataset series should be included in the FPWD for DCAT 3

21:49:31 <alejandra> riccardoAlbertoni_: how to speed up?
21:49:32 <AndreaPerego> q+
21:49:46 <alejandra> +q
21:50:05 <alejandra> AndreaPerego: most of the issues are going to be addressed by the two new sections that we have (versioning and dataset series)
21:50:14 <alejandra> ... and I would close them once we have them in the spec
21:50:22 <alejandra> ... we can create new issues if necessary
21:50:42 <alejandra> ... left other issues not related to versioning or series, and they could be removed if they are not going to be addressed
21:50:56 <alejandra> ... last two can be easily merged
21:51:38 <alejandra> ... no intention for our side on putting restrictions on domain and range

21:53:40 <alejandra> AndreaPerego: two new sections - versioning and dataset series
21:53:53 <alejandra> ... they mention some properties that are not explicitly included in the class descriptions
21:54:00 <riccardoAlbertoni_> q?
21:54:10 <riccardoAlbertoni_> ack AndreaPerego
21:54:17 <alejandra> ... two options: either we include them in the class descriptions or we wait for some feedback
21:54:46 <riccardoAlbertoni_> +1 to postpone the change in the normative part
21:54:47 <alejandra> ... about modifying the class descriptions, we haven't received any feedback, so it might not be worth in getting modifications of the normative part of the document
21:55:43 <alejandra> ... we leave the changes of the normative part for later
