CR Status

RESOLUTION: Approve last week's minutes

ora: we have moved to CR for the first batch of specifications
… it is a big milestone, and I think a bunch of people thought we would never get there
… what is remarkable is that we get substantial participation after 3 1/2 years

pchampin: we have *resolved* to publish them as CR; I submitted the transition request
… if everything goes smoothly, they should be published on 7 April

TallTed: Virtuoso has started RDF 1.2 implementation, passing virtually all tests for the 3 docs to date

<ktk> List with transition announce: https://lists.w3.org/Archives/Public/public-transition-announce/2026Mar/

<ktk> see Friday 27th

ora: I wanted to mention that we should reach out to the implementers that we know
… Also, the Knowledge Graph conference is in the beginning of May, ktk and I will be there
… it is good that we will be in CR by then; we will probably get a lot of questions

ktk: and it is cool that we can report that some implementations are already there

TallTed: that was 3 document out of 27, so it is not that "we are in CR", it is that "we are starting to be in CR"

ktk: we also wanted to propose to prepare a post on LinkedIn about the transition to CR

AndyS: does anything change about how we update documents during CR?
… If you are taking to the KG conference, do we make an effort to quickly put Turtle in the process?
… most examples are in Turtle, more readable than N-Triples

ora: that would be helpful, we have exactly one month

pchampin: once a spec is in CR, we disable echidna, so TR is not updated when we push to the main branch
… but the Editor's Draft is still updated, we can continue working as usual
… I don't think that we can hope to have Turtle published as CR in 1 month

Review of open actions, available at 2

ora: I have not done anything on my actions

niklasl: nothing to report either, waiting for some replies

Review of open PRs, available at 3

pchampin: the "prepare CR snapshop" PRs contain the snapshot submitted for transition request
… I had to include some text describing explicitly the exit criteria
… I didn't wait for the PRs to be merged to make the transition request, though, in the interest of time

pfps: there are some PRs for SPARQL entailment
… I think some of those are ready to go, none really exciting, mostly updating to RDF 1.2 entailment
… Also, what about "common files by reference", are these good to do? I guess there is no hurry

<niklasl> Yes, I think the ones that been merged look fine, so I guess they're all good to go.

pchampin: the "common files by reference" were merged last week on the documents for which I generated CR snapshot, that seemed to go well

ora: what about the diagram of the threat model? pchampin you made some changes?

pchampin: I applied some comments from last week, and made the textual description of the figure part of the caption (rather than hidden in alt text)
… for me it is good to merge

ora: what about PRs on the tests?

AndyS: the protocol one is still under work
… the RDF/XML one needs work on the RDF/XML specification
… they are all progressing
… there is one on sparql-query from pfps, with some suggestions against it

<j22> (note: Jerven has taken the next three fridays off to work on RDF/XML spec)

pfps: [discussions about the suggested changes, about text alignment]

AndyS: I'll put together a summary of the RDF/XML issues that are spreaded around

j22: thanks you

ora: I need to find my ORCID for the RDF/XML

pfps: is it a requirement to have an ORCID for all editors?

j22: not a requirement, but a nice to have

pfps: ok, will look into that for semantics

<TallTed> https://w3c.github.io/rdf-threat-model/

pchampin: the doc itself is just the Respec template; my priority was to provide the diagram

<j22> ORCIDs are nicely LOD curl -L -H 'accept:text/turtle' '

Identifying issues to solve before CR 4

ora: Regarding the Editor's note issue

<ktk> w3c/rdf-concepts#248

<gb> Issue 248 Resolve "Editor's notes" (by afs) [ms:CR] [spec:editorial]

ora: it should be ok, right?

ktk: it should be

ora: also we can close the Horizontal Review tracker for the documents that are transitioned to CR

https://w3c.github.io/rdf-tests/rdf/rdf12/reports/

pchampin: I created this empty page so that the "implementation report" link in the specs does not return a 404
… we need to decide on our process to populate them

ora: what about w3c/rdf-xml#86

<gb> Issue 86 Evolving 1.2 triple term features : rdf:parseType, rdf:annotation (by afs) [ms:CR]

j22: I will be working on that, but I'm not sure to find an elegant solution that everybody will be happy with

<ora> S

AndyS: there is no perfect solution; there is no way to change RDF 1.1 without theoretically breaking some corner cases
… one way that it breaks is about text direction, and it is not even under our control
… the its:dir was previously a property attribute, now it is not
… hopefully, RDF/XML users will be able to give feedback on which use-cases they care most
… I am not to concerned about adding things to the rdf: namespace; if it breaks someone's use-case, too bad
… I also did not know, but we can not currently add the version at the top level

<niklasl> +1 to that

AndyS: If we make breaking changes, we can make it smoother for future versions
… CIM (Common Information Model) is kind of RDF/XML, but based on a pre-1.0 version
… I don't know if it is officially RDF/XML or just happens to be nearly aligned

pchampin: I'm a bit concerned about the TAG review for RDF/XML. We already had to argue about the (less) breaking changes in N-Triples.
… we will need good arguments

<TallTed> possibly helpful -- from https://www.google.com/search?q=%22common+information+model%22+vs+%22rdf%2Fxml%22 -- "In practice, when a utility company needs to export their network model, they use the CIM to define what information to include and then serialize it into an RDF/XML file for the recipient to read. Developers often use tools like the CIMTool (https://cimtool.ucaiug.io/core-concepts/) to bridge the gap between the

<TallTed> UML-based CIM and the RDF-based exchange files."

<j22> For next week, acceptance of breaking changes in other specs was quite high? did that change?

<pchampin> regrets for next week
