- Eduardo: I work for a small mobile content developer in Switzerland, previously worked for Nokia where I was involved in many things including UA-Prof
- 15:09:51 [francois]
- -> http://www.w3.org/2005/MWI/BPWG/Group/TaskForces/CT/editors-drafts/Guidelines/081107 New draft of CT
- 15:10:01 [rob]
- Topic: New Draft
- 15:10:28 [rob]
- jo: I could talk at length on this!
- 15:10:37 [francois]
- -> http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Nov/0017.html Jo's changelog and discussion
- 15:10:45 [rob]
- ... I hope it includes all the resolutions so far
- 15:11:21 [rob]
- ... Hope to gather together anything missing (eg rewriting HTTPS links holes) in the next 2-3 days
- 15:12:10 [rob]
- ... considerable polish is required but would be a waste of time until the substance is stable, which may take another draft
- 15:12:48 [rob]
- ... it will be useful if everyone gives this draft a deep review
- 15:13:06 [rob]
- ... santiy-check and make sure it says what we agreed
- 15:13:13 [rob]
- ... check for consistency
- 15:13:38 [rob]
- ... tighten the nuts and bolts (eg any shoulds that could be musts?)
- 15:13:53 [rob]
- ... and check if clarity can be improved
- 15:14:18 [rob]
- francois: everyone should send comments to the mailing-list
- 15:14:33 [rob]
- ... just like Eduardo has been doing
- 15:14:52 [francois]
- Topic: Content-Location
- 15:15:08 [francois]
- fd: introduced by Rob on the mailing-list.
- 15:16:03 [francois]
- rob: Yes. Don't think there is anything to do, but comes from a long discussion, so I wanted to check whether there was a reason not to include a Content-Location header in the response passed downstream to the phone
- 15:16:25 [rob]
- jo: do we need to propose text around this?
- 15:16:48 [rob]
- francois: Rob's said he doesn't think there is anything to propose here
- 15:17:39 [rob]
- Eduardo: RFC says the value of Content-Location also defines the base URI of the entity
- 15:17:56 [rob]
- francois: that's also one of my fears
- 15:18:06 [rob]
- ... and <link> is more correct
- 15:18:16 [rob]
- q+
- 15:18:24 [francois]
- ack rob
- 15:19:04 [rob]
- rob: I just wanted to see if anyone has a need for this at all
- 15:19:17 [rob]
- ... and so far I've heard no reason to want it
- 15:19:44 [rob]
- francois: could be a way to pass the canonical URI to the client for bookmarking
- 15:20:13 [rob]
- rob: I tried that on a real phone and it doesn't work
- 15:20:37 [rob]
- francois: correct, no-one uses that right now
- 15:20:51 [jo]
- PROPOSED RESOLUTION: No need to mention Content-Location header
- 15:20:57 [rob]
- ... does anyone want us to go to TAG to check?

- Topic: OMA Standard Transcoding Interface
- 15:22:15 [rob]
- francois: no overlap at the moment between OMA doc and our doc
- 15:23:05 [jo]
- zakim, who is here?
- 15:23:06 [Zakim]
- On the phone I see tomhume, Eduardo, francois, rob, SeanP, jo.a
- 15:23:07 [Zakim]
- On IRC I see rob, SeanP, tomhume, jo, Zakim, RRSAgent, francois, dom, trackbot
- 15:23:08 [rob]
- ... OMA doc is an interface for a server, not for a proxy
- 15:23:21 [jo]
- zakim, jo.a is really jo
- 15:23:21 [Zakim]
- +jo; got it
- 15:23:21 [rob]
- ... so there is no incompatibility and no overlap
- 15:23:55 [rob]
- ... but there is some media-transcoding vocab defined that could be useful in future work
- 15:24:40 [rob]
- jo: can we resolve LC-2051 now then?
- 15:24:50 [jo]
- PROPOSED RESOLUTION: ref LC-2051 This is out of scope for our document but may have interest for a general transformation vocab

- 15:26:55 [rob]
- francois: reminder to everyone to propose responses back to contributors ASAP
- 15:28:01 [francois]

- 15:28:17 [jo]
- i/->/Topic: LC-2053
- 15:28:39 [rob]

- 15:38:06 [jo]
- ACTION: casais to review LC-2053 and clarify to group
- 15:38:06 [trackbot]
- Created ACTION-880 - Review LC-2053 and clarify to group [on Eduardo Casais - due 2008-11-18].
- 15:38:30 [rob]
- Topic: Unclear form encoding must be preserved for the server
- 15:38:49 [rob]
- francois: again triggered by one of Eduardo's comments
- 15:40:30 [rob]
- ... current wording is unclear about if a CT-proxy must roll-back encoding changes made in responses when a form is submitted
- 15:40:58 [rob]
- jo: which exceptions are we talking about?
- 15:41:24 [rob]
- francois: section 4.1.5
- 15:41:31 [francois]
- -> http://www.w3.org/2005/MWI/BPWG/Group/TaskForces/CT/editors-drafts/Guidelines/081107#sec-altering-header-values Alteration of HTTP Header Values
- 15:42:43 [rob]
- ... the previous draft talked about Content-Encoding changes in the body, this has been removed
- 15:43:34 [rob]
- jo: we previously talked about transforming request bodies but decided we didn't add much (if anything) to the requirements that already exist
- 15:44:02 [rob]
- ... do we have anything to say on something happening today that we want to stop happening?
- 15:44:41 [rob]
- Eduardo: the mowser transcoder doesn't handle Character-Encoding properly
- 15:45:08 [rob]
- ... eg UTF-8 characters end up as Latin-1
- 15:45:47 [rob]
- jo: mowser hasn't been updated for a while and has lots of bugs, this is a known bug
- 15:46:37 [rob]
- Eduardo: Vodafone ES and PT transcoders don't handle numerical entities well
- 15:47:25 [rob]
- jo: but these are clear bugs, not debatable ambiguities
- 15:48:11 [rob]
- ... so avoiding carelessness or error is not part of our specification
- 15:49:27 [rob]
- francois: we talked about adding Encoding to the appendix E list
- 15:49:57 [rob]
- ... as merely a list of heuristics
- 15:50:02 [jo]
- PROPOSED RESOLUTION: On the subject of character encoding, we have revisited it and we still can't think of anything useful other than "avoid bugs" when transforming between character encoding so we have decided to leave it
- 15:50:32 [rob]
- ... was written as "recoded or restructured"
- 15:51:27 [rob]
- jo: I remember something about this but could not find a resolution to follow when writing the latest draft
- 15:51:48 [rob]
- ... so here is one:
- 15:53:18 [rob]
- jo: I don't think we need to talk about transforming the encoding of a request body
- 15:53:53 [jo]
- PROPOSED RESOLUTION: On the subject of character encoding, we have revisited it and we still can't think of anything useful other than "avoid bugs" when transforming between character encoding and to note that this is an example of a heuristic that the proxy may take into account when transforming content if it thinks that the encoding provided may mis-operate when presented on the client
- 15:54:44 [rob]
- francois: the only case is when the encoding of the response has been changed and the client is then submitting a form from that response
- 15:55:55 [rob]
- Eduardo: this isn't a heuristic, it's a rule
- 15:57:55 [rob]
- rob: yes, the rule is if you change Character-Encoding in one direction (server-to-phone) you have to change it in the other direction (phone-to-server) as well
- 15:59:11 [rob]
- Jo: we're not in the business of specifying how to transform images, HTML etc, so we don't need to specify this either
- 16:00:21 [rob]
- ... this is not our job to write a "building transcoders for dummies" book
- 16:01:36 [rob]
- francois: I second that point, we don't need to expand on that in the Guidelines
- 16:02:17 [rob]
- jo: do we want to add this to 4.2.8.1? Because it's not a heuristic
- 16:02:55 [jo]
- PROPOSED RESOLUTION: On the subject of character encoding, we have revisited it and we still can't think of anything useful other than "avoid bugs" when transforming between character encoding (which we don't intend to say) and add it to the list in 4.2.8.1 so that character encoding is specifically referred to

- 16:05:20 [trackbot]
- Created ACTION-881 - Enact resolution on 4.2.8.1 ref adding character-encoding to the list of format, layout, dimensions etc. [on Jo Rabin - due 2008-11-18].
- 16:06:02 [rob]
- Eduardo: do we need to point out the requirements of what the server expects?
- 16:06:38 [jo]
- PROPOSED RESOLUTION: do not discuss alteration of request body in respect of character encoding
- 16:08:31 [rob]
- francois: do we need to mention that altering the request-body isn't envisaged except "rolling back" changes like Character-Encoding?
