12:14:34 <roba> TOPIC: open action items https://www.w3.org/2017/dxwg/track/products/4
12:14:51 <LarsG> action-193?
12:14:51 <trackbot> action-193 -- Rob Atkinson to Move jmeter test suite to within w3c systems -- due 2018-09-05 -- OPEN
12:14:51 <trackbot> https://www.w3.org/2017/dxwg/track/actions/193
12:15:16 <LarsG> roba: still working on this
12:15:39 <LarsG> ncar: is it planned to do QSA in this test suite, too?
12:15:52 <LarsG> roba: Yes, QSA as fallback
12:16:32 <LarsG> ... also planning to check headers etc
12:17:03 <LarsG> ncar: How to check that all resources are handled according to the spec?
12:17:31 <LarsG> roba: you have to nominate one test resource. You can e. g. use void to find those.
12:17:51 <LarsG> ncar: If there is wide adoption, we cannot rely that resources are RDF
12:18:01 <LarsG> ... so we need as simple a test case as possible
12:18:13 <LarsG> ... without knowledge of data cubes or anything
12:18:25 <LarsG> roba: the tests will be against one known resource
12:18:32 <LarsG> ncar: will use it to test our APIs
12:18:58 <LarsG> roba: delayed due to OGC paper work, not much time for implementation
12:19:26 <LarsG> so we leave action-193 open.
12:20:04 <LarsG> RRSAgent, please draft minutes v2

12:20:37 <roba> TOPIC: review open issues labelled feedback https://github.com/w3c/dxwg/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+label%3Afeedback+label%3Aprofile-negotiation
12:22:19 <LarsG> ncar: we spent last week looking at which issues should be lifted
12:22:30 <LarsG> ... ending with issue #748
12:25:34 <LarsG> ... looking at #785 https://github.com/w3c/dxwg/issues/785
12:25:47 <LarsG> roba: this seems like cartesian products
12:26:16 <LarsG> ncar: we still hae all other dimensions, too
12:26:39 <LarsG> roba: suggest "links should be at the level that the implementation supports"
12:27:09 <LarsG> ncar: this is about a link header saying which profiles are available
12:27:35 <LarsG> ... if you want to know which media types are available there are other methods
12:28:32 <LarsG> ... looking at example 5 in 7.1
12:28:43 <LarsG> ... not current according to the spec
12:29:19 <LarsG> ... all links are resource links with combinations of media types and profiles
12:29:35 <LarsG> roba: there should be nothing magic about it (cartesian product)
12:29:42 <LarsG> ... can type be a list of types?
12:31:31 <LarsG> ... we could answer "yes, it's correct, we just didn't provide an example"
12:31:45 <LarsG> ncar: can we mark it for 3PWD?
12:32:20 <LarsG> roba: if I suggest 10 different profiles and media types (100 possible links):is that unreasonable?
12:32:33 <LarsG> ... should we limit the number of options?
12:32:50 <LarsG> ... are the semantics an exhaustive list or a suggested list?
12:33:03 <LarsG> ncar: should be exhaustive list
12:33:31 <LarsG> roba: so what do you do if you have further dimensions (spatial resolution etc.)?
12:34:07 <LarsG> ncar: Kam is right in that the URI doesn't change if we really do content negotiation
12:34:58 <LarsG> ... so if we just give "link" Profile-URI we should be fine (without type)
12:39:04 <LarsG> <longish discussion about processing of profile vs media type>
12:39:23 <LarsG> <conclusion seems to be that we should focus on profiles>
12:39:39 <LarsG> roba: profile should take presedence if present
12:39:56 <LarsG> ncar: we simply don't say anything about media types
12:40:10 <LarsG> roba: we should change the example so that there is one with an
12:40:32 <LarsG> ... explicit type and one that works dynamically
12:40:56 <LarsG> ... If a resource only supports one particular media type, what should the server say
12:42:05 <ncar> I've used Link headers for pagination and so does GitHub (Issues list)
12:42:22 <LarsG> roba: back to agenda
12:42:41 <LarsG> ... we should address #785 in 3PWD
12:43:03 <LarsG> ncar: the issue is not how link headers work but what we think should be in it
12:45:12 <ncar> LarsG: we should ask Mark Nottingham or dret as they wrote the Link header spec
12:46:20 <ncar> LarsG: we try and solve this within a week and, if not, as them for a special teleconf
12:47:44 <LarsG> roba: OK, so we'll discuss it in the issue
12:48:26 <LarsG> ACTION: LarsG to write proposal in #785 regarding how to handle multiple dimensions in link headers
12:48:26 <trackbot> Created ACTION-326 - Write proposal in #785 regarding how to handle multiple dimensions in link headers [on Lars G. Svensson - due 2019-05-16].
12:50:52 <LarsG> ncar: we should confirm that some issues are _not_ for 3PWD but for 4PWD
12:53:49 <ncar> Milestone Conneg 3PWD: https://github.com/w3c/dxwg/milestone/20
12:56:05 <LarsG> roba: it's a problem to implement conneg when you don't have access to the actual server implementation but only working with redirects
12:56:38 <LarsG> ... i. e. #802
12:56:50 <LarsG> s/#802/#803/
12:57:13 <LarsG> s/#803/#603/
12:58:36 <LarsG> ncar: #504 could be closed as resolved
12:58:48 <LarsG> <all agree>
13:00:37 <LarsG> ncar: #589 should be in the milestone
13:01:25 <LarsG> ... it's about using specific keywords, we don't prescribe that
13:01:56 <LarsG> roba. what about #575
13:03:02 <LarsG> ncar: still significant work. will give it a go in this milestone
13:03:18 <LarsG> roba: points 16 and 17 are addressed already
13:03:38 <LarsG> ncar: we should review #575 in the next sprint
13:04:43 <LarsG> ncar: 14 issues are tagged for 3PWD, is that enough?
13:04:46 <LarsG> LarsG: +1
13:04:51 <LarsG> roba: +1
13:05:04 <LarsG> ncar: will address as many as possible
13:05:35 <LarsG> RRSAgent, please draft minutes v2
