Applying URI-based extensibility in particular is the Web-compatible way of achieving such extensibility. 16:19:46 s/distributed extensibility/distributed HTML 5 extensibility/ 16:20:04 NW: So, do we have consensus?

I could imagine a whole conference on this topic 16:22:02 NM: I thought this was for the whole day 16:22:25 Any interest in inviting Sam Ruby to discuss his views on HTML 5 extensibility? 16:22:34 NW: The message subject is ["possible topic for TAG contribution to TP"] 16:22:58 SW: Is this the subject that we have the most affinity for? 16:23:24 DC: 'We' isn't the point - I have a specific pointI want to get across 16:24:16 NM: Molly was particularly concerned about Adobe's AIR and application construction in general, which would I guess point also to Microsoft's Silverlight 16:24:28 ack DanC 16:24:28 DanC, you wanted to note http://www.w3.org/2007/11/07-TechPlenAgenda.html 16:25:00 DC: The TP programme committee has a list of 20 topics to talk about, see link 16:26:00 Speaking just for myself, I find some of the technical topics we're noodling on here to be more compelling than the rough list at 07-TechPlenAgenda.html 16:26:37 Norm has joined #tagmem 16:26:39 NW: Are we ready for the chair of the TAG to go back to Steve with an overview of what we've discussed, and see where it might fit in? 16:26:50 q? 16:26:57 Action: SW to discuss TAG slot at TP with Steve Bratt, informed by above discussion 16:26:57 Created ACTION-10 - Discuss TAG slot at TP with Steve Bratt, informed by above discussion [on Stuart Williams - due 2007-08-20]. 16:27:24 NW: Same question about the AC -- anything to say? 16:27:37 HST: It's half-a-day, I think we should duck 16:28:52 DC: We don't seem to be doing REC-track work -- if anybody cared I guess we'd hear about it. . . 16:29:29 I agree with Norm, we haven't forgotten rec track work. What we have not done is produce 3 month heartbeats so identified. 16:29:40 HST: At Extreme last week, I got a lot of good response when I pointed people to the [Alternative Representations] finding -- we could just make it a REC 16:30:07 NW: I just don't think our recent work has been REC-like, we're still looking for that 16:30:11 (looking it up... http://www.w3.org/2001/tag/doc/alternatives-discovery.html is dated 1 November 2006 ) 16:30:52 NM: I think a lot of our recent pubs can be seen as a heartbeat 16:31:15 (our last WD was http://www.w3.org/TR/2006/WD-namespaceState-20060329/ ) 16:31:27 NM: Most recent approved finding was Metadata finding, at beginning of the year 16:32:47 DC: We have to do a written report which summarises what we've done 16:33:03 ... If anyone objects, we'll here about it 16:33:38 Action: SW to tell Steve Bratt that the TAG doesn't want a slot at the AC meeting 16:33:38 Created ACTION-11 - Tell Steve Bratt that the TAG doesn't want a slot at the AC meeting [on Stuart Williams - due 2007-08-20]. 16:34:10 Topic: TAG blog entry: Version identifiers 16:34:24 NW: Who has not read it : HST, DC, TVR 16:34:39 NM: It's not long, shall I walk through ito 16:34:45 s/ito/it?/ 16:35:00 NW: Go ahead then 16:35:12 http://www.w3.org/2001/tag/2007/08/versionBlog.html 16:35:13 NM: We've gotten some pushback from DO and Mark Baker 16:35:14 -> http://www.w3.org/2001/tag/2007/08/versionBlog.html 16:37:46 (hmm... it's not clear that the quoted GPN is quoted, especially when the one that's not quoted looks the same) 16:38:15 [Scribe not trying to transcribe NM's walkthrough] 16:38:24 [this bit about xml 1.1 is awfully relevant, and yet it's not in there? odd.] 16:39:09 [perhaps the xml 1.1 versioning situation fits better in a separate item.] 16:40:26 [the "ASCII doesn't have a version identifier" example that Noah often uses isn't in here. odd.] 16:41:39 q+ to observe that "will change in incompatible ways" asks about the future 16:41:40 q+ to be confused 16:41:48 ack ht 16:41:48 ht, you wanted to be confused 16:42:51 q+ to add that finding mixes "identifying version" with the specific technique of adding a "version attribute" -- 16:43:39 HST: There's a shift between "provide for marking version" and "when to mark version" in your prose 16:43:48 ... That seems to me to take us off track 16:44:29 NM: I think those are closely related -- if you would never want to mark the version, then the language shouldn't provide the mechanism for you to do so. 16:45:26 q+ to note that many of the questions the article raises are associated versioning strategy associated with (all versions of) the language. 16:46:50 HST: My understanding of the existing BPN is that if you _don't_ give people a way to mark versions, they will make one up, which will not be interoperable, so even if you don't know for sure what it will be used for, you should leave a place for it 16:47:07 NM: If you can't spec. what the version indicator means, you shouldn't have it in your spec. 16:47:19 [I hear Noah defending his position but not convincing HT. I think the article is interesting as is, and I'd like to see it go out signed "Noah, a TAG member" and let other TAG members respond with other articles or comments.] 16:47:27 ... You will just be storing up trouble for the future, c.f. XML's version attribute 16:49:04 HST: Brings us back to the metapoint as to what the status of TAG blog entries should be -- the settled will of the TAG as a group, or an opportunity for TAG members to discuss something using the blog medium? 16:49:11 NM: DO said something similar 16:49:41 SW: I think the value of a blog would be lost if it required consensus 16:49:46 q? 16:50:00 TVR: I agree, we shouldn't turn TAG blog entries into mini-findings 16:50:40 NM: I think we should reserve the possibility that we do both, that is, we may sometimes want to publish something _with_ consensus 16:50:55 (sure, a little telcon preview is a good thing, from time to time) 16:51:18 +1 to DanC 16:51:19 ... and that I _can_ ask for telcon review on how to make the best posting I can, before I post it 16:51:31 But not that I have to ask for it 16:52:01 NW: So it you remove "for the T A G" from the bottom, you can publish as and when you choose 16:52:03 ack Norm 16:52:03 Norm, you wanted to observe that "will change in incompatible ways" asks about the future 16:52:27 +1 to the proposal on blog entries 16:52:35 q? 16:52:38 ack raman 16:52:38 raman, you wanted to add that finding mixes "identifying version" with the specific technique of adding a "version attribute" -- 16:53:06 NW: I'm also not sure that I'm unhappy with the existing GPN -- I'm not happy with the idea that the spec. author has to tell in advance whether there will ever be incompatible changes 16:53:48 TVR: Just to make sure that we're not just talking about version attributes alone as the way of indicating version 16:53:57 NM: We get to namespaces in the last section 16:54:27 TVR: What about DOCTYPE line as a version identifier, which is what the HTML WG are going back and forth about 16:54:32 q? 16:54:35 ack Stuart 16:54:35 Stuart, you wanted to note that many of the questions the article raises are associated versioning strategy associated with (all versions of) the language. 16:55:11 (er... let's not leave posting mechanics in the someday pile, please.) 16:55:37 SW: The questions raised by the article are closely related to the terminology and analysis in the Versioning finding we're working on 16:56:06 ... I think Mark Baker's comment [link] are along the same lines 16:56:59 NM: I thought his comments (about header metadata) were strictly-speaking out of scope, because the BPN is about _in-band_ identifiers, but metadata is _out-of-band_ 16:58:30 DC: Movable Type is weblog support software, in some ways the first one 16:59:11 ... Karl duBost installed it for W3C and interface it with our CVS system -- this is good, but does introduce a 15-minute delay 16:59:23 Actually, media type is in-band from the point of view of an HTTP response, but we're talking here about specifications for and instance of particular data formats. In general, I don't >think< it's likely that media-types play a big role in the in-the-file versioning formats. Right? 16:59:58 ... It supports categories, so if you categorise things they get syndicated, and can then be grabbed by a web page 17:00:00 (yes, analagous to http://www.w3.org/html/ ) 17:00:40 NM: What about formatting: monospace, display, etc? 17:01:14 DC: Karl is pretty good with CSS, I don't know what would happen if I added my own. . . 17:03:11 NW: Summarising -- Karl's setup can easily be expanded to allow us to log in, author new entries, categorise them as "TAG" and feed our blog page 17:03:30 SW: Different from B2 Evolution -based blogs? 17:04:07 DC: Yes -- advantage is it's baked not fried -- that is, the HTML is constructed only once, not on demand from a SQL DB 17:04:18 +Dave_Orchard 17:04:54 TVR: I don't mind what the content management is as long as it doesn't get in the way by producing opaque URIs 17:05:21 DC: I think we will got good URIs from Movable Type, including year, month and words from the title 17:05:38 topic: location of the TAG blog 17:06:16 -> http//www.w3.org/blog/tag/ 17:06:16 (do I read this correctly? 4 objections to ?) 17:08:08 That option was added late, so the no-entries may just be ones who never saw it 17:08:10 Should we just do a prefer/live-with on the two surviving options right now on the phone? 17:08:24 Yes, something like that. 17:08:32 (I suspect http://www.w3.org/blog/tag/ is technically tied to b2evolution) 17:09:05 +1 17:09:17 +1 to /tag/blog 17:09:24 Proposed: http://www.w3.org/tag/blog/ 17:09:57 SW: DC, can you organise the top-level 'tag' directory that we will need? 17:10:08 DC: Not without approval from TimBL. . . 17:10:38 DO: We can resolve on /tag/blog, pending approval 17:10:57 NM: I don't think we're in a great rush 17:11:13 No objections. 17:11:17 NW: OK, lets try /tag/blog 17:11:37 Resolved: To locate the TAG blog at http://www.w3.org/tag/blog 17:11:49 Action: DC to try to reach TBL to get approval 17:11:49 Created ACTION-12 - Try to reach TBL to get approval [on Dan Connolly - due 2007-08-20]. 17:11:52 Proposed title: TAG Lines 17:12:01 NW: Any objections to TAG Lines? 17:12:35 Resolved: The TAG blog will be called "TAG Lines", using the mechanisms established by Karl duBost 17:13:22 Action: DC to ask KdB if categories can be restricted to particular login lists 17:13:22 Created ACTION-13 - Ask KdB if categories can be restricted to particular login lists [on Dan Connolly - due 2007-08-20]. 17:13:43 zakim, who's making noise? 17:13:55 Norm, listening for 11 seconds I heard sound from the following: Dave_Orchard (15%) 17:15:52 NM: We should try to use the description of whatever category we pick to make clear that it's for TAG members only 17:16:17 DC: I'd be happy if Yves Lafon wrote something about caching for him to use the category 'web architecture' 17:16:33 HST: Then we shouldn't use 'web architecture' for the TAG blog 17:17:02 NM: So two categories then, 'web architecture' and 'TAG Member', and I should use both for my post? 17:17:06 DC, HST: Yes 17:17:20 topic: httpRange-14 finding status 17:17:30 q+ 17:17:42 RL: New draft coming soon, significantly changed, lots of new material 17:17:58 ack Stuart 17:18:25 ... available soon, then I'm mostly away until just before the f2f, so you all can review 17:18:57 SW: I think we've had problems if we try to discuss things that aren't public. . . 17:19:20 RL: My plan was to put it in public space, but not announce it publicly 17:19:31 DC: Hmmm, I'd rather it were just out there 17:19:44 RL: But I won't be available to answer comments 17:20:08 NM: I've found that just saying that works pretty well 17:20:29 RL: OK, I'll go ahead and do that 17:20:54 topic: Request from Ted Guild for BP Note on caching schema documents 17:21:44 NW: Background: W3C servers get hammered by tools which don't cache schema documents which they request very frequently 17:21:55 TVR: I don't see that this is a TAG issue 17:23:35 HST: I think it's a TAG issue, but not restricted to schema docs -- the Web provides for caching, if you anticipate large volumes of traffic from your site, or sites which use your software, to one or more stable resources, you should provide for caches 17:23:59 q+ davo 17:24:06 ack davo 17:24:20 NM: More than that, I think our interest here follows from the advice to use only one URI for any given resource 17:24:53 DO: New issue or not, I think we should take it on, because it follows from our advice on avoiding multiple URIs 17:25:11 ... We should follow through on the ramifications of our recommendations 17:25:15 (it's also true that people shy away from http URIs because they fear their server will melt down.) 17:26:01 name brainstorm... httpCaching... hotSpot... 17:26:09 NW: I hear consensus we should take this up.

Web frameworks running on end-user-machines don't have caching proxies necessarily 17:29:02 TVR: The architectural problem is in part that the publisher of a popular URI cannot in general ensure responsible caching by clients 17:29:18 q+ to point out MSoft's response 17:30:03 q+ to suggest advice should include advice to folk deploying such static resources to set expiry time 17:30:04 NM: But we do expect providers of e.g. popular home pages to scale up the servers in keeping with demand 17:30:28 ("economics aside" is not a tactic I want us to take. I want us to keep economics in mind.) 17:30:35 ack ht 17:30:35 ht, you wanted to point out MSoft's response 17:30:38 q- 17:30:42 ... So maybe the W3C is actually at fault here -- what's the division of responsiblity between provider and consumer 17:30:57 FWIW: I the reason I thought this discussion was useful was to >scope< the issue, which I think should go beyond caching 17:31:32 ...scalabilityOfPopularResources 17:31:44 scalabilityForPopularResources 17:31:59 (I prefer URI to resource in this case, even though it's wrong. But oh well.) 17:32:25 cachingBestPractices 17:32:35 On economics, I agree, but when you say "ignoring economics for the moment" helps you to tease out which compromises you're making for mainly technical and which mainly economic. I claim that if W3C's funding were like Google's, they might not bother to lock out people who hit them at the rates we see. 17:32:51 scalabilityOfURIAccess 17:32:57 But yes, the fact that many providers can't afford to scale is a crucial (economic) piece of the puzzle. 17:33:25 Proposed: The TAG accept a new issue, scalabilityOfURIAccess-58 17:33:43 aye, and I don't care about the number 17:34:02 Resolved: the TAG accepts a new issue scalabilityOfURIAccess-58 17:34:27 NW: Someone willing to summarize this and send it to the list? 17:34:45 DC: NW, did Ted Guild's message cover the background? 17:35:08 NW: Not all.
