SPECIFICATION: 10:16:25 Raphael to fix the weird character in the spec document 10:16:25 CLOSED: http://lists.w3.org/Archives/Public/public-media-fragment/2010Jan/0102.html 10:16:31 3.1 Media Fragment URI syntax: (Yves) 10:16:38 Bug in the npt specification: 10:16:38 Philip: http://lists.w3.org/Archives/Public/public-media-fragment/2009Nov/0023.html 10:16:38 Dom: http://lists.w3.org/Archives/Public/public-media-fragment/2010Jan/0093.html 10:17:11 erik: we changed from abnf to ebnf (?) yves, is your action still valid? 10:17:13 yves: yes 10:17:13 zakim, unmute me 10:17:13 silvia should no longer be muted 10:17:33 silvia: is there an issue with the change? 10:17:52 yves: no, i am using abnf for other things, but i'm sure ebnf shall be similar 10:18:01 silvia: then we only have the parsing issues dom mentioned, which are minor 10:18:16 yves: the npt definition was not exactly correct, that was the only thing holding up the grammar 10:18:26 silvia: yes, as discussed in email, just a small change 10:18:32 yves: i will look at that before the f2f 10:18:38 (but i will be away next week) 10:18:42 zakim, mute me 10:18:42 silvia should now be muted 10:19:02 3.2 Protocol for URI fragment Resolution in HTTP 10:19:25 zakim, unmute me 10:19:25 silvia should no longer be muted 10:19:33 Erik: any problem with the changes proposed by Philip? 10:19:56 silvia: no, they clarify things, they might have made the document structure more complicated. philip also proposed some changes to document structure but they make sense 10:20:00 erik: i agree 10:20:31 jackjansen, i would be against a structure where normative and non-normative are not separated. I would like them to be clearly spaced 10:21:08 silvia: we should put an overview table at the end of the document of what is normative and informative, rather than spreading it through the document. most of it is obvious, but it is important to put the info in one place 10:21:31 jackjansen, the nice thing about a table is that if it indexes all the normative stuff, you can use it to find what you actually need 10:21:56 jackjansen, not sure i like the idea that it should be clear from the wording, because then in non-normative text you have to refrain from using SHOULD, MUST etc. 10:22:06 jackjansen, it should be clear from the layout which is which 10:22:31 silvia, comments in-line about what is normative is not useful 10:22:52 jackjansen, in SMIL spec, we put in text markers for people who use screen readers etc. (as well as colors) 10:23:14 jackjansen, in the published document there are only text markers -- the visual markers were not included 10:23:38 davy has joined #mediafrag 10:23:41 silvia, make a note now, put these in if we come to committee draft 10:23:58 jackjansen, the xml format we use has a way to distinguish paragraphs, so if we use that we can modify the layout in stylesheet 10:24:13 davy, distinguish in screen and aural? 10:24:32 jackjansen, just use the xml to make a clear distinction between normative and informative text 10:25:10 s/davy/thierry 10:25:43 http://www.w3.org/TR/2008/REC-SMIL3-20081201/smil-structure.html 10:26:16 thierry: we should put a div with class="normative" or class="informative" 10:27:12 ACTION: Erik to mark up the spec with normative and informative classes 10:27:13 Created ACTION-134 - Mark up the spec with normative and informative classes [on Erik Mannens - due 2010-02-10]. 10:27:43 thierry: do we also want to have text saying "this section is normative"? 10:27:51 silvia, that can be part of the style 10:28:36 silvia, i guess the table is already in the document, but a table at the end with a reference to the normative parts would be nice 10:30:06 ACTION-123: Yves to come up with ABNF for header syntax 10:30:06 ACTION-123 Come up with ABNF for header syntax notes added 10:30:35 erik: action 133 is ongoing 10:31:11 yves: re: action 123, need to find the proposal from the archives 10:31:23 Review of the complete Section 5.2.1 for group approval 10:32:06 postponed (we have not all yet reviewed it) 10:32:30 erik, this should be done before the f2f 10:33:03 silvia: i have read it and am happy with it, apart from minor issues in the ebnf; dom also suggested to put the ebnf syntax together in one place; maybe we should just repeat it all at the end 10:34:09 silvia, he made a few changes to make it easier to read, along the lines of the html5 spec 10:34:23 silvia: i'm happy with what he's done, i don't have any issues 10:34:29 erik: ok, tbc 10:34:36 3.3 Rendering of Media Fragments URI in UA: 10:34:44 ACTION-130 10:34:53 Silvia to draft a new subsection in the Section 5 regarding the rendering in the UI of media fragments, at least for the temporal dimension 10:35:05 silvia: i sent an email just before this meeting 10:35:23 silvia: i've put a paragraph into section 5.1.4 10:35:25 http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#processing-overview-interpretation 10:35:40 so basically the action is done 10:36:12 silvia: davy, i've made a mention of spatial,track dimensions 10:36:22 davy: ok, i'll work over that too 10:36:46 jackjansen, i really like silvia's suggestion, but we should make sure that in the protocol we have enough detail to actually implement it 10:37:28 jackjansen, which touches on issue 5, similar to silvia's note about the temporal domain, but in the spatial domain 10:37:47 jackjansen, we should ensure that the server provides any information such as width, height etc. so that clipping can be implemented client-side 10:38:11 silvia, we need to specify these things for each dimension, please add a paragraph 10:38:38 jackjansen, also at the end of section 5.1.4, a very simple graphic of a timeline of a video playing would be handy to help with understanding the intention 10:38:51 close action-130 10:38:51 ACTION-130 Draft a new subsection in the Section 5 regarding the rendering in the UI of media fragments, at least for the temporal dimension closed 10:39:44 action: davy,erik to extend section 5 regarding spatial and track dimension 10:39:44 Sorry, couldn't find user - davy,erik 10:40:23 action: erik to extend section 5 regarding spatial and track dimension 10:40:23 Created ACTION-135 - Extend section 5 regarding spatial and track dimension [on Erik Mannens - due 2010-02-10]. 10:41:15 action: davy to create a diagram of video timeline to explain temporal dimension 10:41:15 Created ACTION-136 - Create a diagram of video timeline to explain temporal dimension [on Davy Van Deursen - due 2010-02-10]. 10:41:31 action: jack to check that 5.1.4 is implementable using the protocol 10:41:31 Created ACTION-137 - Check that 5.1.4 is implementable using the protocol [on Jack Jansen - due 2010-02-10]. 10:43:16 3.4 Discovery of 'Track' and 'Named' fragments: 10:43:27 silvia: nothing to discuss yet, this is being worked on in ogg 10:43:36 3.4, 3.5 to be discussed later on 10:44:03 5. TEST CASES: (Michael) 10:44:17 erik: i'm in favour of making next phone conf all about test cases, for a whole hour 10:44:35 q+ 10:44:58 silvia, last week we mentioned that the foms people would be keen to have an indication on which sections are fairly ready, and my suggestion was that section 5.2.1 can be implemented 10:46:04 the only indication of stability is publishing LC or CR 10:47:57 conrad: perhaps we don't need to specify that the mechanism for handling client-side fragments involves http byte-range requests: just specify that "if the client can already seek over the network, honor this fragment syntax" 10:48:38 silvia, last week we decided that rather than pulling out parts of the document which are stable, we simply mark within the document how mature each part of the document is, so implementers can go ahead 10:48:56 silvia, whereas last call etc. is really for the whole document; we don't want to hold back implementers 10:49:01 Zakim, mute me 10:49:01 Conrad should now be muted 10:49:27 Yves, the parts which are unstable may lead to changes in the parts we think are stable now 10:49:34 silvia, unlikely as that section is really trivial 10:50:02 jackjansen, that section has very little value with out parts of chapters 3, 4 10:50:17 jackjansen, i like the sentiment about allowing implementers to start implementing stuff, but ... 10:50:32 silvia, yes, but we have already been through section 3 substantially, any changes will be minor 10:51:12 jackjansen, i probably agree, but then even if we mark sections as "stable" we should specify that it may change anyway. we don't want to be editing for all eternity like the whatwg is doing 10:51:36 silvia, we should start having implementations. we are really close to having the temporal stuff finalized, even though the headers etc. may still be under discussion 10:52:04 silvia, if we keep working on the spec without any implementations, it's not going to move ahead in a reasonable amount of time 10:52:22 jackjansen, if we mark these things as not "stable/unstable" but "reaonsably stable, mature" etc. that is fine with me 10:52:37 silvia, "ready for test implementations" would be a useful indication 10:52:39 erik: fine by me too 10:52:45 4. ISSUES 10:52:49 conrad, I'd like a note "for test implementation" or something. 10:53:04 issue-4.1 10:53:24 erik: postpone non-active issues 10:54:02 5. TEST CASES 10:54:17 jackjansen, is a phone conference the best medium for discussing details of test cases? 10:54:55 silvia, i agree -- we should prepare the group for the meeting re: test cases, but it is up to michael 10:56:08 silvia, whether we prepare for the test cases next week or not, we should at least talk about it then 10:56:36 6. IMPLEMENTATION: 10:56:43 erik: any news? 10:57:05 none 10:57:10 all ongoing 10:57:15 7.
