11:05:22 <LarsG> TOPIC: Open actions from last meeting
11:05:30 <LarsG> https://www.w3.org/2023/09/06-dxwg-minutes#ActionSummary
11:05:55 <LarsG> roba: first action (access for Nick) has been resolved
11:06:31 <roba> https://github.com/w3c/dx-connegp/pull/49
11:06:36 <LarsG> ... Nick has made some pull requests
11:08:26 <LarsG> roba: https://www.w3.org/2023/09/06-dxwg-minutes#a02 (reactive, proactive cneg)
11:09:01 <LarsG> YoucTagh: Has updated issue
11:09:48 <LarsG> https://github.com/w3c/dx-connegp/issues/39
11:12:23 <LarsG> roba: behaviour is acceptable. If you ask for a profile
11:12:33 <LarsG> ... but the media type is noc available, you should
11:12:49 <LarsG> ... answer 406 (never return a media type the client
11:12:55 <LarsG> ... didn't ask for)
11:12:56 <pchampin> q+
11:13:23 <LarsG> YoucTagh: media type is one of the dimensions in http
11:13:35 <LarsG> ... if the default representation does not have the
11:13:57 <LarsG> ... requested media type, we can specify that in the
11:14:15 <LarsG> ... link header, so the client would know that anyway.
11:14:53 <LarsG> ... If the server doesn't want to  send a default representation
11:15:11 <LarsG> ... it would return 406
11:16:36 <LarsG> YoucTagh: In reacztive CNEG, the I-D specifies using HEAD to query for the
11:17:01 <pchampin> q-
11:17:17 <LarsG> ... supported profiles. That should be 300.
11:19:07 <LarsG> https://github.com/ProfileNegotiation/I-D-Profile-Negotiation/issues/28
11:21:26 <LarsG> roba: If a client uses HEAD without specifying a profile,
11:21:37 <LarsG> ... the server should answer with the default representation
11:21:49 <LarsG> ... including all headers
11:25:18 <pchampin> q+
11:25:38 <YoucTagh> https://www.rfc-editor.org/rfc/rfc9110.html#section-9.3.2
11:25:55 <LarsG> YoucTagh: according to the spec, the response headers for GET
11:26:12 <LarsG> ... and HEAD need not be the same.
11:26:47 <LarsG> ack pchampin
11:27:29 <LarsG> pchampin: http semantics says that the answer to HEAD
11:27:50 <LarsG> .. request should be the same as for a GET (i. e. the headers)
11:28:07 <LarsG> s/should/SHOULD/
11:28:23 <LarsG> ... that should go for the status code, too
11:28:46 <LarsG> roba: The question is if the server returns 200 or 406 for
11:28:58 <LarsG> ... a request for a header/profile combination it cannot
11:29:03 <LarsG> ... support
11:31:45 <pchampin> q+
11:32:11 <LarsG> ... we need to make decision on that
11:32:16 <LarsG> ack pchampin
11:32:48 <LarsG> pchampin: it would be important to discuss this with the IETF group
11:35:39 <LarsG> ACTION: roba to word-smith a proposal for 200 vs 406
11:35:52 <LarsG> TOPIC: IEtF
11:36:13 <LarsG> pchampin: At TPAC there was a meeting with IETF people,
11:36:46 <LarsG> ... concerns that the ProfNeg spec is more IETF tha  W3C
11:37:05 <LarsG> ... there are companion documents in IETF space
11:37:27 <LarsG> ... their advice would be send this to the http WG at IETF
11:37:50 <roba> q+
11:37:56 <LarsG> q+
11:38:17 <LarsG> ack roba
11:38:37 <LarsG> roba: sees the benefit of having the protocl side done in one place
11:39:06 <LarsG> ... W3C work includes an ontology with semantics
11:39:29 <LarsG> ... and the QSA side doesn't fit with IETF, either
11:40:29 <LarsG> ... the W3C work should refer to IETF docs, not duplicate them
11:40:42 <LarsG> ack LarsG
11:41:28 <roba> LarsG: have been working on this for 5 years with Rueben Verbourgh and Herbert van Soempel
11:41:49 <roba> ... were rejected by the IETF protocol working group - would be happy to recontact
11:42:46 <LarsG> ... main contacts Martin Thompson and Mark Nottingham from http WG
11:44:32 <LarsG> pchampin: large part of the spec is in W3C space, but the
11:44:45 <LarsG> ... protocol part should be IETF
11:45:01 <LarsG> LarsG: the I-D is at https://profilenegotiation.github.io/I-D-Profile-Negotiation/I-D-Profile-Negotiation.html
11:45:14 <LarsG> s/the/The proposed/
11:46:03 <LarsG> ACTION: pchampin to contact Martin Tompson and Mark Nottingham in order to get a liaison
11:46:55 <LarsG> TOPIC: rest of actions...
11:47:42 <LarsG> roba: Action to prepare PR for #45 (https://www.w3.org/2023/09/06-dxwg-minutes#a04) is still open
11:48:33 <LarsG> YoucTagh: There is a branch for that
11:49:09 <LarsG> ... questions about some examples
11:49:26 <LarsG> roba: A 4.2 is just an example, shouldn't be in the same PR
11:51:18 <LarsG> YoucTagh: format(s) should be consistent with link hint spec (https://datatracker.ietf.org/doc/html/draft-nottingham-link-hint-03#name-formats)
11:53:50 <LarsG> ... has updated references (how do we reference RFCs?)
11:54:10 <LarsG> ... will try just using RFC...
11:54:26 <LarsG> TOPIC: Open Pull Requests
11:55:12 <LarsG> roba: Nick has done a change to use JSON-LD at some places, too
11:55:26 <LarsG> ... we should be able to merge that
11:55:43 <LarsG> ... <assigning YoucTagh as reviewer>
11:55:59 <LarsG> ... merging that directly
11:56:31 <LarsG> ... PR #48
11:57:30 <LarsG> ... here Lars needs to review
11:57:58 <LarsG> ... and Nick make to changes requested by YoucTagh
