- 10:15:04 [raphael]
- Yves started to do it during the f2f meeting, needs to add a sentence in the spec
- 10:15:19 [raphael]
- ISSUE-19?
- 10:15:19 [trackbot]
- ISSUE-19 -- Parsing must be defined normatively in the MF spec itself -- open
- 10:15:19 [trackbot]
- http://www.w3.org/2008/WebVideo/Fragments/tracker/issues/19
- 10:15:56 [raphael]
- Philip has proposed a number of patches, see result at http://people.opera.com/philipj/2010/11/04/media-fragments-spec/overview.html
- 10:16:44 [raphael]
- Yves has discussed this with Philip which sort of outdate this proposal
- 10:17:06 [raphael]
- Yves: the result is that we should keep the grammar as it is, + some clarification text on the purpose of the grammar
- 10:17:41 [raphael]
- ... + a normative algorithm for parsing
- 10:18:05 [raphael]
- ... we need consensus and approval from Jack, Silvia, and Davy at least in the group + feedback from the implementers
- 10:18:46 [silvia]
- is the proposal formally specified somewhere?
- 10:19:04 [silvia]
- I'm probably ok with it but don't want to give a blind vote
- 10:19:20 [raphael]
- Raphael: what this clarification text should express?
- 10:19:20 [Yves]
- the purpose of the grammar is to describe the "normal" syntax, ie: the one that should be created
- 10:19:45 [Yves]
- ie: it is not the parsing rules
- 10:19:56 [raphael]
- Raphael: where we should write this ?
- 10:21:25 [raphael]
- Yves: at the beginning of section 4 and appendix D
- 10:21:34 [raphael]
- ... as a reminder
- 10:22:36 [raphael]
- ACTION: raphael to add a clarification text regarding the purpose of the grammar
- 10:22:36 [trackbot]
- Sorry, couldn't find user - raphael
- 10:22:42 [raphael]
- ACTION: troncy to add a clarification text regarding the purpose of the grammar
- 10:22:43 [trackbot]
- Created ACTION-199 - Add a clarification text regarding the purpose of the grammar [on Raphaël Troncy - due 2010-11-24].
- 10:23:04 [raphael]
- Raphael: regarding the parsing algorithm
- 10:23:26 [raphael]
- Yves: back to a very detailed description of the algorithm
- 10:23:38 [raphael]
- ... I would like to read it crisp and procedural
- 10:24:12 [raphael]
- ... we need an agreement that the parsing algorithm become normative
- 10:24:53 [raphael]
- ... I would agree that given this clarification of role, the algorithm become normative
- 10:24:59 [raphael]
- Erik: I agree too
- 10:25:53 [raphael]
- Silvia, would you have any objection of having a detailed parsing algorithm of a media fragment URI nomative in the spec instead of an annex?
- 10:26:30 [raphael]
- Tow versions of the algorithm
- 10:26:33 [raphael]

- 10:28:06 [raphael]
- ... and http://people.opera.com/philipj/2010/11/04/media-fragments-spec/overview.html#processing-name-value-lists
- 10:31:53 [silvia]
- no objection here
- 10:33:46 [raphael]
- Raphael: I agree to ask Philip to put which version he prefers
- 10:33:57 [raphael]
- ... the only contentious issue might be: 2.
- 10:33:57 [raphael]
- 2. Otherwise, the name-value pair does not represent a media fragment dimension. Validators should emit a warning. User agents must ignore the name-value pair.
- 10:33:57 [raphael]
- Note: Because the name-value pairs are processed in order, the last valid occurence of any dimension is the one that is used.
- 10:34:38 [raphael]
- Raphael: Validators should perhaps emit an error rahter a warning ?
- 10:34:47 [raphael]
- s/rahter/rather
- 10:35:26 [raphael]
- ... the processing order of the dimensions and whether parsing should be relaxed or not in case of multiple occurences of the same dimension (except track)
- 10:36:23 [raphael]
- ACTION: troncy to send a proposal to close ISSUE-19 that consists in: clarification text + normative parsing algorithm
- 10:36:23 [trackbot]
- Created ACTION-200 - Send a proposal to close ISSUE-19 that consists in: clarification text + normative parsing algorithm [on Raphaël Troncy - due 2010-11-24].
- 10:36:41 [foolip]
- I prefer my latest version that uses the namevalues syntax
- 10:37:06 [raphael]
- great, thanks Philip, we will use this one then :-)
- 10:37:25 [raphael]
- Topic: 3. Media fragments URI on web page
- 10:37:55 [raphael]
- Raphael: started by a thread from Silvia
- 10:38:02 [raphael]
- ... discussed at the F2F meeting: http://www.w3.org/2010/11/02-mediafrag-minutes.html#item05
- 10:38:33 [raphael]
- ... lead to the notion of optimistic use if the Range header, only for the second unit
- 10:38:50 [raphael]
- ... it cannot be done for any other way for getting part of the content
- 10:38:52 [Yves]
- s/second/'second'/
- 10:38:54 [silvia]
- (except that my email was about something completely different ;-)
- 10:39:15 [Yves]
- yeah I think Silvia's email was about using the html fragment for video
- 10:39:37 [raphael]
- s/use if/use of
- 10:39:40 [Yves]
- which by default is => no (ie: it's per page, so you can't generalize this)
- 10:40:14 [silvia]
- it was not to become normative - the idea is to propose a syntax that people can choose to make use of
- 10:40:59 [silvia]
- because the html URI is much more important for most video on the web than the video URI
- 10:43:45 [raphael]
- Yves: there are 2 orthogonal issues
- 10:44:00 [raphael]
- ... the fragment applies to ONE resource you're retrieving
- 10:44:24 [raphael]
- ... if you want the fragment on the page be applied to the video element on that page, this is your javascript that can do that, nothing to put in the spe
- 10:44:27 [raphael]
- s/spe/spec
- 10:45:30 [raphael]
- ... the other issue of optimistic use of the Range header, Philip states that this is up to the URI spec to change
- 10:45:37 [raphael]
- ... I quote: "The semantics of the fragment identifier is defined by each MIME type registration. Before we know the type, we can't assume anything. Therefore, the only possibility is if the URL/URI/IRI spec itself states that #t=1 has some semantics for *all* types and that this should cause headers Foo and Bar to be sent. However, I truly doubt we'll see media-specific things like this put into URL/URI/IRI, it's seems like a gigantic layering violat
- 10:46:21 [silvia]
- as I said: the idea is to give a Web developer that wants to do media fragments on a Web page a recommendation for how to do the URI structure on their page - they still have to implement it themselves, it's just handy to agree on the same approach
- 10:46:57 [silvia]
- no need for more Range headers, or an implementation in browsers or anything - just a helping hand for Web developers
- 10:46:58 [raphael]
- Raphael: I agree silvia, and I strongly recommend to add a new Appendix for what you propose, note to developers :-)
- 10:48:00 [foolip]
- Agreed, as long as there's no change in UA behavior for #t=1 for HTML I'm fine with recommending web developers to use the syntax
- 10:48:10 [silvia]
- btw: all the video hosting sites already have such approaches in the URIs so it's not theoretic
- 10:48:37 [Yves]
- I agree that we can't assume anything, and we shouldn't break any layer, but if we know enogh context, using Range request with a unit that can only be applied to the media type we are targeting (and will default to normal behaviour for all the others)
- 10:48:45 [raphael]
- Silvia, would you like to have an action to write a paragraph, note to developers, that they can easily implement a javascript to forward the hash on the URI to the video element?
- 10:48:58 [Yves]
- is a (not nice) possible optimisation
- 10:49:00 [silvia]
- yup, no problem
- 10:49:06 [silvia]
- just don't know when I'll get around to it :)
- 10:49:23 [Yves]
- context should be that URI is in a <video> tag
- 10:49:33 [silvia]
- sure
- 10:49:59 [raphael]
- ACTION: Silvia to write a paragraph, note to developers, that they can easily implement a javascript to forward the hash on the URI to the video element
- 10:49:59 [trackbot]
- Created ACTION-201 - Write a paragraph, note to developers, that they can easily implement a javascript to forward the hash on the URI to the video element [on Silvia Pfeiffer - due 2010-11-24].
- 10:50:48 [raphael]
- Raphael: it is part of my action to clarify the use of optimistic use of Range header optimization in case we are in the right context <audio> or <video> element

- ah ok - cool
- 11:14:08 [silvia]
- are you using media frag URIs?
- 11:14:41 [tomayac]
- saying hi to silvia on the google internal chat ;-)
- 11:14:58 [tomayac]
- silvia, if you check the app demo, there're anchors on the left pane
- 11:15:02 [silvia]
- lol
- 11:16:10 [tomayac]
- at this point in time the app uses only the simplest possible media fragments, but looking into implementing temporal and spatial as well
- 11:16:54 [silvia]
