Group reports

Karen asks Jaroslav to show the requirements in an organised way

Jaroslav: people need to clone the repo …

<roba> Jaro - - can you share your screen?

The problem is that the github link shows the content not the rendered page

See https://‌w3c.github.io/‌dxwg/‌ucr/#

Jaroslav describes the buttons in the page that act as filters.

These work on a local clone of the repo, but not at https://‌w3c.github.io/‌dxwg/‌ucr/#

Karen: I think we need a little more for how to organised the use cases and requirements. As a group we will need to prioritise them and decide in any of them should be dropped

Javoslav: if we are only interested in the requirements, we could do that with some further coding.

Karen: we’re looking for a prioritised list of requirements as we had for the data on the web best practices work.

Rob: the two options are either to go through the requirements individually, or for the people who provided the original use cases and to say of they are happy that the requirements have been adaequately described

<Caroline> DWBP Use Cases and Requirements https://‌www.w3.org/‌TR/‌dwbp-ucr/

Karen: I don’t see this as an either/or choice

Rob: I am not expecting the descriptions to be set in stone too early

I am happy to deal with the editing process as we go

Karen: I agree with the process of refining the requirements as we move forward

I think the UCR task group could make some valuable assessment at an early stage

Jaroslav: could we stick with filtering and add other criteria

Jaroslav: I looked at the DWBP but note that they had a different target for their work

Jaroslav discusses ideas for adding further context to the document

Rob suggests some ideas for grouping requirements

Jaroslav: perhaps we can discuss this offline?

What is the purpose of restructuring the requirements? What ideas are there?

Karen: asking people on the mailing list about ideas for clustering requirements would be valuable

Peter: a graphical depiction of clustering could be helpful

Jaroslav will contact Peter to discuss this further

Karen: we will continue this on email

Use cases

Karen invites Peter to talk about use case ID50

See https://‌w3c.github.io/‌dxwg/‌ucr/#ID50

This relates to changes when data is added or removed across different versions of a dataset

Karen: any comments?

Rob: I don’t have any problems with the use case, apart from it being written more as a requirement

I suggest we review the requirements to see if they express the behaviour we need

Karen: I don’t see the links to Peter’s …

Rob: this is still work in progress

Jaroslav_Pullmann: I understand that this could be interesting. This is about changes to context.

Jaroslav asks Peter about the scenarios where this matters

Peter: it determines the kinds of people who need to be involved e.g. IT experts versus others

Jaroslav is concerned about contracts being broken …

Peter: my focus here is on information content, and whether something is new or has been taken away

Thomas: it sounds to me like an application of the same dataset, so we don’t need …

Peter: what about de-duplification ?

Thomas explains …

Karen: what hasn’t been covered in existing use cases?

Rob: it concerns multiple things, the data set, the metadata, …

Karen: even though we feel there is some duplication, can we vote on whether we feel this use case is worth including?

Jaroslav: I consider this use case as highlighting a new aspect on versioning

<Makx> Additional use cases should always be useful.

<Makx> Happy to help there too

<Thomas> thx makx

Karen: it sounds like this use case would benefit from rewording to make it sound more like teh others

<Thomas> PWinstanley_: what's essential is whether the information content is changed or not.

Karen: no objections so resolved

Resolved: ID50 is in scope for DXWG use cases with additional edits by Peter

<Thomas> if the content stays the same but the format/bitesyze/... differs I don't thing we can talk about another version (at most a new version of a distribution)

<Thomas> (my two cents)

<Thomas> can we decide versioning req's in four minutes?

<Thomas> lol

Jaroslav asks Karen if she wants to talk about requirements in respect to versioning

<Thomas> have to catch a train - apalogies for leaving now

Karen: that’s it for today, I can’t make next week’s call and will see you all in two week’s time

We should discuss the clustering and classification of requirements by email in the meantime.

<RiccardoAlbertoni> Thanks, have a good week!

<annette_g> Thanks, all!

<AndreaPerego> Bye!

Jaroslav suggests looking at how this has been done in other groups.

<Jaroslav_Pullmann> bye!

<LarsG> Thanks, bye

<Stijn_Goedertier_AIV> Thanks everyone
