… Discovery: Service names have been registered with IANA, some fixes are in work.
… Profiles: We had a resolution in the profile call to publish a WD update. We should also make the resolution here.

<McCool> proposal: publish the current editor's draft of wot-profile (after fixing a Respec error) as a WD immediately

RESOLUTION: publish the current editor's draft of wot-profile (after fixing a Respec error) as a WD immediately

… on Wed / Thu we will put them into the template, we need to create a new draft prior to the meeting.

Liaisons

McCool: Mkoster, any thoughts on CHIP?

Koster: We should just agree to renew the ability to work together
… BACnet: Will try to set up a brief meeting.

McCool: Intel is intertested in Matter - home assistant includes a Matter bridge.

Koster: protocol bridge is not difficult. Semantic bridge is more challenging.

McCool: We will explore next year
… DTDL: Will revisit next year, it would be nice to reengage

TF reports

McCool: TD: a couple of implementations are only a corner case, we have some gaps
… Architecture: I already mentioned the PR
… Discovery: a few gaps around sorting and security
… Marketing: mostly organisational discussions, clarifying responsibilities

Kaz: TF mainly thinks about Website maintenance, we should also talk about CG collaboration in general, e.g., how to bring input from the CG participants back to the WoT-IG/WG

McCool: If we have an implementer with a acommercial solution, how to get feedback into the spec
… people could create issue, we need to clarify the policy

Lagally: CG should channel people to the IG / Use Cases TF to collect use cases and requirements
… IG should channel potential contributors to the WG

Kaz: Agree, and that's why I gave a comment about that during the Marketing call yesterday. We should clarify the procedure to handle the CG input in addition to the concept within the CG Charter.

McCool: Let's create an issue for the marketing TF to define procedure
