Meeting Content Negotiation Subgroup
<RubenVerborgh> https://github.com/w3c/dxwg/issues/239
RubenVerborgh: interesting work done by Nick, but it's only one
… way of doing it
… we should try to be more webby
… The proposal is more about change of URLs, we should try to use
… links. We need a sustainable solution.
<roba> hi - can you identify the webex url plz
antoine: UC has not yet been accepted
… We need to clarify if this is about negotiation or about serving a profile
RubenVerborgh: Nick's solution is to circumvent accept headers
… since that seems too complicated
<roba> Re the UC - its one i'm very familiar with from the UK and Simon's "sissvoc" experience. We have three options:
<roba> 1 nothing,
<roba> 2 state that URL parameters may override headers if an API supports profile negotiation
<RubenVerborgh> *roba, will you join on WebEx as well?*
<roba> 3 define a canonical parameter syntax
<roba> * yes - but i havent found the right webex link - not listed at https://www.w3.org/2017/dxwg/wiki/Meetings
roba: The issue is that Nick's UC conflates several issues
… 1 is about delivering a description
… 2 can you specify a profile using a parameter in the URL overriding headers
… 3 the last is about locale and content type
<RubenVerborgh> foo/resource/
<RubenVerborgh> foo/resource.html
RubenVerborgh: we shouldn't mandate a syntax, the overriding aspect is OK, but we shouldn't call it "override"
<RubenVerborgh> foo/resource.en.html
RubenVerborgh: it's just a kind of already negotiated version.
… you cannot negotiate the representations
roba: The headers might be ignored if you specify in the URL
RubenVerborgh: Yes, but it's already negotiated
roba: We should allow this to be a case and then we're set
RubenVerborgh: We could link to the representations. The URL solution doesn't
… allow discovery
roba: Right, but how to do that is an open question
… Question is if ProfileDesc is an appropriate solution
… You can use web linking using different syntaxes
antoine: This UC is about using an http API to get data about profiles?
roba: It's about two things
<RubenVerborgh> *we needed Zakim :-)*
antoine: would like to see the arguments in the context of a full URL
roba: This might need to be factored out as two requirements:
… 1 The values in the URL to take presedence over headers
… 2 giving the right format
antoine: Is this both about negotiation and representations?
roba: This is about negotiation for data, the profile is a powerful way
… to negoriate for that
… currently it's largely focussed on metadata being available
… negotiation for profile is also in the UC
… the UC could be made more clear.
antoine: the main UC is to be able to negotiate, the ancillary is
… to get the metadata
Action: antoine to call for more clarification on candidate UC 239
<trackbot> Created ACTION-121 - Call for more clarification on candidate uc 239 [on Antoine Isaac - due 2018-05-30].
RubenVerborgh: Does anyone know timeline for guidance document
antoine: first draft ready for TPAC in October
RubenVerborgh: Will work on IETF document
… those we can work on in parallel
antoine: it would be a great help if the documents are kept orthogonal
… and the negotiation document shouldn't say what a profile is
… I think that's your approach.
roba: The document should stand alone and replay an agreed definition
antoine: yes
roba: Lot's of discussion on the profile definition language. Not really helpful.
… The UCs are pretty small, and we need to work on how to define a profile
<RubenVerborgh> q ack
<antoine> https://www.w3.org/2018/05/09-dxwg-minutes#x05
antoine: timeline, we need something for TPAC but the document should
… be well underway in August. That makes a two month's difference
… FPWD early August
