Agenda and minutes

1. Admin

   • Continuation with subgroups and main group (only reminder)

   • Email list, subject prefixes, email archive (public) (only reminder)

   • Confluence pages: purpose, updates (only reminder)

   • Possible use of Google docs

     • Who could create this?

     • Folders per subgroup should be then located below a main folder, (relevant info linked from the Confluence site).
       Google docs structure for DDI working groups also for DDI-CDI subgroups. Flavio will file an issue. TC will look into it. A generic solution would be great.

2. CDI Webinar
   Darren will set up a Google document where ideas can be collected. The topic will be again discussed in two weeks.

3. Review and publication of CDI article
   Paper on “DDI-CDI and other Standards” can be reviewed by the group until Friday, March 7, 2025. It can be published as DDI Alliance paper (where it will get a DOI). It should be listed in the related page and linked from the DDI-CDI page.

4. Questions from the sub-WGs

5. AOB
   Consistency of associations names in RDF and other encodings should be discussed. This will be addressed by the syntax representations subgroup. Information on the issue will be sent to the group.

DDI-CDI WG Meeting – 12 February 2025

In attendance: Darren Bell, Deirdre Lungley, Hilde Orten, Wendy Thomas, Joachim Wackerow, Arofan Gregory, John Kunze, Flavio Rizzolo

Agenda:

(1) Admin, if any 

(2) Finalisation for the public release of 1.0

(3) Organising sub-groups and meetings

(4) AOB

Discussion Points

1. Deirdre to meet with Benjamin regarding joint meeting between Implementation and Tools groups, will e-mail if further action needed (joint meeting, issues etc.)

2. Achim proposes to have a dedicated list for DDI-CDI, with subgroup prefixes. Use e-mail as first step, then escalate issues to the generic group, then meet if needed.

From an e-mail exchange (Achim):

With the background that subgroups are starting now, it would be really great if we can use soon the CDI Google group email list for the communication. The advantage would be that an email group archive develops then. All subgroups should use this email list. Each subgroup should have an acronym which can be the prefix in the email subject (like: [mod] subject). This way the subgroup can be identified easily and everybody is informed what is going on. Suggested acronyms:

·       nq  Quali

·       mod Modelling

·       doc Documentation/Community Implementation Guide

·       map SDMX-DDI Mapping

·       sr  Syntax Representation

·       et  Example and Tools

·       w3c W3C Alignment

• Will need public access to the e-mail archive. Link from Confluence. Only members can post to it - access would be read only.

3. The DDI-CDI 1.0 release is just waiting on the announcement in the newsletter. (Jared says there will be both a general announcement and the newsletter, released later today.) Should we do a webinar? We could do a written announcement for e-mail lists, and then do a webinar of it can be organised. Darren will pursue the webinar.

4. Will rely on Hilde/Achim/Libby to organise meetings during Arofan's medical leave. Next meeting will be in two weeks. Hillde will send e-mail announci9ng the next meeting.

5. Final open questions from release discussions. These are minor points in e-mails between Darren, Achim, Wendy and Arofan. Address at next meeting. Darren will follow up with Achim.

DDI-CDI WG Meeting – 5 February 2025

In attendance: Darren Bell, Deirdre Lungley, Hilde Orten, Benjamin Beuster, Dan Gillman, Wendy Thomas, Joachim Wackerow, Arofan Gregory, John Kunze, Flavio Rizzolo

Agenda:

(1)   Admin

Arofan to go on Medical leave as of February 16. Achim, Hilde, and Libby to fill in chair temporarily.

(2) Finalisation for the public release of 1.0 - Achim's questions

·       HTML request for RDF namespace needs a new page, Darren to create

·       Add links to field-level documentation (without “RDF” in the path) – not a replacement for the RDF links. This does not need content negotiation, as it is essentially a link to the model.

·       Remove RDF XML version until we follow up with Pierre Antoine (Fuseki auto-conversion)

·       Redirects needed to support relative links in field-level doc will be added

·       We will distribute the “unique names” version of the model, and add a comment that additional versions are available in the download package

All changes to be made by this coming Friday.

(3) Hilde asked some additional questions:

·       Testing for/model additions for new data structures new (e.g. NetCDF)? (Could be important of CLIMATE-ADAPT)

Dan Gillman and Flavio Rizzolo are both interested in this issue, which we should discuss with the CDIF effort covering the same thing. This may not end up in CDI beyond the logical description, but we should have one solution.

·       Proposals/model snippets for changes to or new things for CDI, processes.

Raise specific issue in the CDI WG and we can deal with them.

·       Status of SHACL/ ShEx – are they sharable (even if not published)?

CLIMATE-ADAPT ontologist wanted access to this. Deirdre has decent SHACL, but the ShEx is not working as well. We could share the SHACL as a work-in-progress. Not very time-urgent. Do in the next couple of weeks. Achim, Hilde, and Deirdre to sort out as they work on this., Also share with Doug Fils for CDIF – he could use the CDI SHACL.

(4) Organisation and schedule moving forward

We will meet next week, and then shift to meeting every other week. We will try to get Libby to join. There will be further e-mail communications.

(5) AOB

[Hilde is in Athens with free ice cream. Darren says “Beware of Greeks bearing gifts…”]

None.

DDI-CDI WG Meeting – 29 January 2025

In attendance: Darren Bell, Deirdre Lungley, Hilde Orten, Benjamin Beuster, Dan Gillman, Wendy Thomas, Joachim Wackerow, Arofan Gregory, John Kunze

Agenda

1. Admin, if any 

·       Report to SB still TBD

·       Wendy to send Arofan minutes in collapsable Minutes on Confluence

2. Finalisation for the public release of 1.0

Everything is now in the repository and is correct.

Process: we send TC an e-mail with final locations. Need to establish a full download package location (with everything in the release). Currently the full download package is in GitHub. Wendy will ask people in TC (Olof, Dan Smith) and get an answer as to how to produce the needed ZIP from GitHub.

Achim will transmit the download package to TC once he knows how to do it. There may also be a partial download package just for the field-level documentation.

We now have a product page on the new Alliance website, as well as a page per version for each spec. Once done, we can review (links are not yet final.)

3. Hilde's credit issue

From Hilde:

The list is here: Cross Domain Integration (CDI) Working Group

In the short version of credits at the field level doc. These are mentioned:

Contributors to DDI-CDI Development

Members of the Cross Domain Integration (CDI) Working Group shepherded the standard into its final form and produced the final documentation. Listed in alphabetical order they are:

• Arofan Gregory (chair)

• Dan Gillman

• Flavio Rizzolo

• Hilde Orten

• Jay Greenfield

• Joachim Wackerow

• Larry Hoyle

• Oliver Hopt

• Wendy Lee Thomas (Technical Committee contact)

I would suggest to add the following members to this short list (alphabetical):

• Benjamin Beuster

• Darren Bell

• Deirdre Lungley

• John Kunze

Proposed fix:

Add heading before Spreadsheet paragraph on ddi-cdi/CREDITS.md at main · ddi-cdi/ddi-cdi

“Members of the Cross Domain Integration (CDI) Working Group since 2023”

• Benjamin Beuster

• Darren Bell

• Deirdre Lungley

• John Kunze

Achim will make this change. John’s affiliation is Drexel University Metadata Research Center.

4. Testing the field-level doc

Arofan and Deirdre have played with the current version and it seems to be working as intended.

5. AOB

Subgroups:

These need to start – people should respond to Dan (etc.)

We will meet next Wednesday, and then shift to meeting every other week

Achim raised the issue of issue-tracking the high-level and field-level doc. We could use the old bug-tracker? Or we could just add a new label to Github? Consensus is to stick w/Githun with a new label (or a label for each).
