13:56:39 [noah]

VQ: Our main goal for this meeting is to figure out our goals and strategies leading to, say, 2006

13:56:46 [noah]

VQ: propose to discuss every morning?

13:57:47 [noah]

DC: is all morning too much time.

13:58:24 [noah]

TBL: Dave should be there, especially for discussing web services arch?

13:58:38 [DanC_mtg]

Amy, DaveO said he plans to call in to this meeting around now; I wonder if there's a number for him to call

13:58:38 [noah]

HT: Should spend at least this morning, and should do round robin.

13:58:42 [DanC_mtg]

ok, I'll get the one from your office and bring it up

14:00:53 [amy]

do you also want a bridge for all three days?

14:01:04 [noah]

TBL: may not make 8:30, but start without me

14:02:29 [noah]

NM: Suggest we start 8:30 and do issues of minor interest until Tim shows at 9.

14:04:13 [noah]

VQ: As to rest of agenda, I've listed some other issues and findings to be considered. Got these by reviewing prev telcon minutes. I missed the one Dan wanted to raise.

QT F&O Namespace document: http://www.w3.org/2005/04/xpath-functions/

14:05:59 [noah]

DC: My concerns cross several of these. I want to review the namespace document for the XQuery stuff. That relates to namespaceDocument-8, abstractComponentRefs-37, and possibly some others. This is not a new issue, but relates to several existing.

14:06:46 [noah]

XXX SCRIBES NOTE TO SELF: put in ref to Query note.

14:07:44 [noah]

HT: I would like to talk more about security issues later.

14:08:41 [noah]

NM: Note that I sent a draft on schemeProtocols-49. See http://lists.w3.org/Archives/Public/www-tag/2005Jun/0024.html and http://lists.w3.org/Archives/Public/www-tag/2005Jun/0025.html . Read it before our discussions of that issue if you have a chance.

VQ: Current schedule is for 20-22 September in Edinburgh, Scotland

14:09:55 [noah]

HT: We may be invited to dinner Tues night, please let me know if any spouses are likely to attend.

14:10:35 [noah]

HT: OK, I'll assume 9 +/- 2. That uncertainty is no problem.

VQ: there is an AC meeting in Montreal

14:15:06 [dorchard]

dorchard has joined #tagmem

14:15:11 [noah]

VQ: Tech plenary will be in late Feb, early March, probably on riviera.

14:15:58 [ht]

will do

14:16:07 [noah]

NM: What if we do tech plenary to meet other groups, and then split difference to do late fall,

14:16:17 [noah]

s/fall,/fall?/

14:16:34 [noah]

HT: Right, which puts us at the AC meeting in Montreal late November.

14:17:46 [noah]

VQ: Dates of AC are Nov. 29 - Dec. 1 in Montreal

14:18:57 [noah]

VQ: Who will go in Montreal. Many positive responses. Dave O. says he cannot travel that entire week.

14:19:40 [noah]

HT: What about week before. Uh... US Thanksgiving.

14:20:03 [noah]

DO: Proceed without me. I'll be in Edinburgh.

14:22:01 [noah]

HT: What about Mon Tues week after XML 2005.

14:22:05 [noah]

NW and HT: Doesn't work.

14:22:28 [noah]

TBL: more travel this fall is tough.

14:23:19 [dorchard]

Could do nov 29, Dec 2 TAG meeting.

14:23:34 [noah]

NM: Tim, is there any way to line this up with the AC meeting for you?

14:23:48 [noah]

HT: Uh...won't there be a team meeting Friday after the AC?

14:23:53 [noah]

TBL: Actually, somewhat unclear.

14:25:01 [noah]

Various: What about 5th and 6th December?

14:25:04 [noah]

TBL: Where?

14:25:13 [noah]

HT: Kansas City?

14:25:14 [DanC_mtg]

considering 5-6 Dec... Montreal ... or Cambridge...

14:25:25 [noah]

Various: What about Cambridge?

14:26:07 [noah]

DO: What about straddling AC?

14:26:13 [noah]

NW: Rather not.

14:26:23 [noah]

VQ: What about 5&6 here?

14:27:16 [DanC_mtg]

(yes, there's a w3c team day Fri 2 Dec. 99%odds. planning in the works)

14:27:30 [noah]

VQ: Dave O., can you make that?

14:27:58 [noah]

DO: scribe perceives a mumble from Dave that sounds like a yes.

14:28:33 [noah]

RESOLVED: We will have a TAG meeting for 2 days in Cambridge hosted by W3C 5-6 December 2005

14:29:03 [noah]

RESOLVED: We will have a TAG meeting in conjunction with the Feb/March 2006 Tech. Plenary in France, exact dates TBD.

14:32:18 [noah]

Topic: Summer vacation plans

14:32:27 [noah]

VQ: I have to decide my summer vacation dates.

14:32:51 [noah]

VQ: Propose not to be involved first 3 weeks of August.

14:39:14 [noah]

We spend some time proving that for every week over the summer, at least one person is missing.

14:39:51 [noah]

Proposal: we will have calls through 20th of July, then take a break with next call being 23rd of August.

14:40:03 [noah]

Tim and Noah, as well as others, will miss some in July.

14:41:55 [noah]

s/through 20th/through 19th/

14:45:29 [noah]

Topic: Document management

14:45:55 [noah]

From the agenda: "Should we revise the way we maintain the issues list and pending actions?"

14:46:24 [noah]

VQ: Should I be doing more about document management?

14:46:34 [noah]

VQ: Norm is tracking errata?

14:46:54 [noah]

NW: Right, but a bit behind. Will find time to do an errata doc soon.

14:47:00 [noah]

VQ: OK, action is continuing.

14:47:37 [noah]

VQ: We also have the public list public-webarch-comments@w3.org Mail Archives

14:47:50 [noah]

VQ: are we monitoring sufficiently?

14:47:56 [noah]

DC & NW: yes, we are.

14:48:46 [noah]

VQ: We also have the findings list. Noah has sent a new draft.

14:49:11 [Norm]

NM's new finding: http://lists.w3.org/Archives/Public/www-tag/2005Jun/att-0024/schemeProtocols.html

14:49:32 [noah]

Actually, the stable link should be: http://www.w3.org/2001/tag/doc/SchemeProtocols.html

14:49:55 [noah]

I just fixed it. Was broken over the weekend due to messing up the checkin of png's.

14:50:45 [noah]

Some discussion of whether to put drafts on the findings list or only approved.

14:50:57 [noah]

DC: OK either way as long as it's clear, but I don't need unapproved there.

14:51:06 [noah]

VQ: I'll keep them straight.

14:51:35 [noah]

ACTION: Vincent to add draft finding on schemeProtocols-49 to findings page (link is http://www.w3.org/2001/tag/doc/SchemeProtocols.html)

14:52:07 [noah]

VQ: any more logistics

14:52:19 [noah]

??: any more discussion where to put minutes?

14:52:25 [noah]

HT: I'll let it go?

14:53:43 [noah]

NM: I recall that there was a strong push that something stable be linkable by the time the next agenda goes out. So, we're deciding that anything table is OK?

14:53:50 [noah]

Various: right.

14:54:04 [noah]

TBL: Well, uh stuff in email attachments isn't easily fixed,

14:54:21 [noah]

Various: right, and that takes us into the discussion that we're not reopening, so we won't.

14:54:29 [noah]

Topic: Goals and Plans for Future Tag work

14:54:46 [noah]

VQ: we've had various inputs from various people on this

14:55:19 [noah]

VQ: one question is, what do we plan to produce as documents?

14:55:52 [noah]

VQ: that said, I propose we first discuss long term directions, then the right documents to produce

14:56:18 [noah]

VQ: First document was Noah's

14:56:45 [noah]

NM: No, actually first was from Tim: http://lists.w3.org/Archives/Public/www-tag/2005Apr/0054.html

14:57:29 [noah]

TBL: My feelings unchanged since writing the note.

14:57:42 [noah]

TBL: WebArch doc seems to have been effective. The form worked well.

14:58:34 [noah]

TBL: let us discuss both the core findings and the rationale behind them

14:59:05 [noah]

TBL: therefore, prefer to grow the scope, while working in the same general framework and style

14:59:28 [noah]

TBL: semantic web and web services seem to be the two major scopes to consider

15:00:23 [noah]

TBL: could look for other high priority issues as well, but mainly looking for high priority ones. Probably things like httpRange-14 are best seen in the context of the larger architectural issues.

15:01:07 [noah]

TBL: somewhat tricky...in the first phase we claimed to have topic experts in the room, that may be less true as we move into semantic web and web services. In those cases we serve more as journalists.

15:01:40 [noah]

TBL: there has been a lot of formal work done on sem web, but could be better integrated and tied into Web arch itself.

15:02:49 [noah]

TBL: on web services, the last effort at architecture, didn't gel. Some concern that the folks who drive web services haven't put in place enough clean architecture for us to help crystalize.

15:03:32 [timbl]

TBL: If we were to work on WS arch, we would not be documenting retrospectively but doing design work, it seems.

15:03:49 [timbl]

TBL: ... And it isn't design work which we shoul dbe doing.

15:03:53 [noah]

HT: We started on web arch 10 years after the web, sem web would be 5 years, arguably on web services it isnt; there yet.

15:04:27 [noah]

HT: we do better when there is an established body of practice. The current experts don't always give you clean answers.

15:04:45 [noah]

ER: But in my experience, that's exactly where we could make a contribution.

15:04:52 [noah]

TBL: doesn't ws-i do that?

15:04:56 [noah]

ER: does architecture follow?

15:05:25 [noah]

DC: W3C looks better looking back.

15:06:01 [noah]

DC: we don't want to be saying "stop, or I'll say stop again"

15:06:55 [noah]

TBL: sometimes W3C needs to do design, but not TAG

15:07:33 [noah]

TBL: TAG designs mainly at the level of doing glue to cover things that don't line up

15:09:07 [dorchard]

q+

15:12:14 [DanC_mtg]

ack dorchard

15:12:53 [noah]

NM: I think our main responsibility to Sem Web and Web services should be to (a) make sure they use the core mechanisms of the Web itself appropriately and (b) in doing that, see whether they teach us more about what we need to document about the Web architecture itself.

15:13:39 [noah]

DO: Web Services does indeed deviate from core web architecture more than Sem Web. For example, the first versions of SOAP didn't do HTTP Get.

15:14:07 [noah]

DO: Clearly Web Services doesn't use the RESTful mechanisms of uniform interfaces.

15:14:34 [noah]

DO: now with WSA we see lack of use of Web Arch primarily for creating asynchronous stateful services.

15:15:12 [noah]

DO: service will have stateful instance, and you'll want to have async interactions with that. Client doesn't know much about state, except for need to echo things.

15:15:47 [noah]

DO: there is very little reuse of REST

15:16:15 [timbl]

q+ to agree that Web Services are fundamentally different architecture - a remote operations architecture, not an information space architecture. These are distinct patterns, and both have their uses. One can build one on top of the other, either way up, but one doesn't have to pretend that they are the same or should be the same.

15:16:59 [noah]

q+ to say that we may need to be a bit more careful about the layering of our use of the term Web. Is the Web really only REST, or is REST just the most widely deployed part.

15:17:25 [noah]

DO: note that cookies are widely used on the web for stateful things. We can learn some messages from those.

15:17:40 [ht]

q+ to ask where "The W W W" starts and ends

15:18:20 [noah]

DO: we've not necessarily made it easy. SOAP Response hasn't been well adopted. Maybe if the web were more friendly to stateful interaction, WS would have an easier time leveraging the Web.

15:18:21 [Vincent]

ack DanC-mtg

15:18:44 [noah]

DC: Henry asks "who are our customers"?

15:19:09 [noah]

DC: history is, we were started to answer questions about whether W3C workgroups were or were not using Web Architecture well.

15:19:40 [noah]

DC: what we wrote is what everyone in every WG ought to know.

15:20:00 [noah]

DC: I'm not convinced we can impact the web master community.

15:20:05 [timbl]

ack tim

15:20:05 [Zakim]

timbl, you wanted to agree that Web Services are fundamentally different architecture - a remote operations architecture, not an information space architecture. These are distinct

15:20:08 [Zakim]

... patterns, and both have their uses. One can build one on top of the other, either way up, but one doesn't have to pretend that they are the same or should be the same.

15:20:08 [Vincent]

ack tim

15:20:33 [noah]

TBL: agree with David, Web Architecture is different architecture from REST.

15:21:08 [noah]

TBL: our scope is what happens in W3C. Originally was information space, but now there's more overlap, e.g. between web and email than there was before.

15:21:42 [Vincent]

ack noah

15:21:42 [Zakim]

noah, you wanted to say that we may need to be a bit more careful about the layering of our use of the term Web. Is the Web really only REST, or is REST just the most widely

15:21:44 [timbl]

q?

15:21:46 [Zakim]

... deployed part.

15:21:53 [noah]

TBL: I therefore think it's reasonable to to WS arch if we want to because w3c does that

15:21:56 [noah]

scribe: ht

15:22:26 [ht]

NM: Return to the note I wrote:

15:22:29 [Norm]

http://lists.w3.org/Archives/Public/www-tag/2005Jun/att-0001/Priorities2005.html

15:23:08 [ht]

NM: Remember the slogan "Lead the Web to its full potential"

15:23:35 [ht]

WebArch1 covered much of the foundations of that, the Web as it was say 5 years ago when most of the foundations were new and cool

15:24:02 [ht]

... Going forward we should be looking at what will be pervasive 5 years from now

15:24:35 [ht]

... Even wrt the information space, the growth points are not all in our current portfolio, e.g. peer-to-peer, streaming hypermedia

15:25:03 [ht]

... More care needed wrt layering our story about the Web:

15:25:10 [ht]

... 1) Names of things

15:25:32 [ht]

... 2) Schemes that are deployed that you can use with names (all of them)

15:25:42 [ht]

3) RESTful schemes

15:25:52 [ht]

4) Widely deployed media types

15:26:11 [ht]

... So saying "the Web is REST" is to take a big jump in that layering

15:26:40 [ht]

... We can use the word 'Web' for a particular level of that layering, but that has consequences

15:27:24 [ht]

... Because it moves widely used and arguably important uses of the technology 'outside the Web', which may not be the right thing to do

15:28:06 [ht]

... So is RESTful really == 'the information space', or can we bring more of e.g. Web Services into the information space

15:28:29 [ht]

... What if POST was not POST [scribe hopes NM will fill this in, didn't get it]

15:29:24 [ht]

... Opportunities may be there to stretch the information space, beyond the home-base (REST) we start from, to a much wider range of things that have names out there

15:29:38 [dorchard]

q+ to mention Web service "info space type" things not on the web

15:29:58 [ht]

... We may decide that REST really is the core, and we should set the bar really high

15:30:10 [Vincent]

ack ht

15:30:10 [Zakim]

ht, you wanted to ask where "The W W W" starts and ends

15:30:21 [ht]

... Or we could say that there's a way of moving beyond GET, PUT etc. which expands what we can do

15:30:26 [noah]

scribe: noah

15:30:58 [noah]

XXX Scribe note to self...need to reword HT's capture of what Noah said.

15:32:34 [noah]

HT: people are confused about distinction between Internet and Web,who invented which, etc.

15:33:15 [noah]

HT: the stuff we call the Web is what is layered on one of the protocols in particular, I.e. HTTP

15:33:19 [DanC_mtg]

(hmm... this lecture Henry is talking about is interesting... IEEE, IETF, W3C / ethernet, Internet, Web ... I'm very interested in how people learn about these technologies)

15:34:58 [noah]

HT: in private discussion, Noah tried to convince me that Web was bigger and embraced everything that could be linked through URIs

15:35:20 [noah]

HT: reading the Arch document, doesn't tell you where not to go.

15:36:20 [noah]

HT: how should I know when I'm not on the Web and whether I think the Web Arch doc should apply?

15:37:05 [noah]

TBL: we found the question am I on the Web not helpful. We did find: "is this document helpful?" to be a more useful question.

15:39:43 [dorchard]

q?

15:42:04 [noah]

TBL: I thought Noah was splitting hairs, but then I understood is peer to peer example.

15:44:51 [dorchard]

q?

15:45:49 [noah]

NM: I'm actually trying to draw parallel between things like P2P and Sem web. Both of them get great value from being integrated into what we know as traditional web. Each stretches the web in new directions. Sem web because it names things not connected to computers, P2P because it deals in new types of content and security.

15:45:59 [noah]

TBL: Anyone claiming web is HTTP-only?

15:46:09 [noah]

Noah: I thought maybe Henry.

15:46:23 [noah]

HT: Statefulness is important. Security is important.

15:46:44 [noah]

HT: in particular, having your identity established makes a big difference.

15:46:49 [timbl]

Noah, http://www.w3.org/DesignIssues/diagrams/URI-space.png

15:47:02 [Roy]

The Web has never been HTTP-only (started with FTP and Gopher, added HTTP and WAIS, ...)

15:47:06 [noah]

HT: for example, I get something different from W3C retrievals than you do, because I'm served by the European server.

15:47:25 [noah]

DC: why is that a problem, it's the same resource?

15:47:42 [noah]

HT: but it breaks more often than others.

15:48:14 [noah]

NM: I think Henry's point is that many things in practice depend on the system knowing who you are and where you are

15:48:40 [noah]

HT: Google, in particular, tailors results based on partition of IP space. Cookies are another example.

15:49:03 [noah]

HT: Most commercial sites give you a very different experience according to your cookies, and thus in a sense identities.

15:49:56 [noah]

HT: I tried to convince Google that Web would sort of survive if something like Google disappeared. They felt it was "constitutive" of what the web is.

15:51:46 [dorchard]

+1 to HT's point that Google is part of the architecture from the user experience

15:51:56 [noah]

HT: note that which URI you get redirected to from google.com depends on (your IP address? something not covered in Web Arch)

15:52:19 [DanC_mtg]

(hmm... I could replay the whole "commonname" discussion in the TAG context, I guess, re one of HT's points about search engines)

15:52:42 [noah]

HT: partially connected and disconnected are also important. What about push (see RIM Blackberry)

15:52:56 [DanC_mtg]

(what does RIM do different? gee... I don't even know)

15:52:58 [noah]

ER: are you also going toward mobile web?

DanC_mtg, you wanted to offer to project and edit an outline and to realize that the long tirade I occasionally give on how broken authentication in the web is might be relevant

15:54:33 [Zakim]

... here. There are only a few parties who can get authenticated services deployed. enticing people to use cleartext passwords should be criminal

15:54:59 [noah]

DC: I had offered to edit outline, looks like won't happen before lunch.

15:55:44 [noah]

DC: I have a document from long ago about web forms and having authentication and a logout button using MD5. They said the would do it in next version. Hasn't happened.

15:56:12 [noah]

DC: there are limits on who can deploy authenticated services because of limits on number of passords users will maintain.

15:56:57 [noah]

DC: as alternative, small sites are using clear text passwords, sometimes without HTTP due to inability to afford compute power for doing HTTPS.

16:02:01 [noah]

DO: On Web Services side, consider WS Resource Framework. Describes generic operations, you can get, put, etc. content of these resources. They use WS-Notificiation to allow publish/subscribe for state changes.

16:02:56 [noah]

DO: these are note computational, they are information resources. But even in these constrained cases, they still don't use HTTP protocol fully. Don't use HTTP GET. Still do SOAP messages over HTTP post. Want to be able to use WSA End Point References.

16:03:49 [noah]

DO: I did a proposal at their first meeting to show how to offer these on the web. Why not use a binding that binds down to HTTP Get? They said: good ideas, but we're (Oasis-based team) aren't the ones to do it.

16:04:18 [ht]

HST agrees that state and side-effect are worthy of further discussion, for sure

16:11:46 [Vincent]

Lunch break

16:12:02 [Vincent]

We reconvene at 1:00 pm Eastern time

16:13:19 [noah]

NM: Tried (and largely failed) to convince Tim and others that one difference about Web Services is that more interactions are secured, and that more have state-changing effects at the resource owner. Therefore, Noah claims, the particular value that comes from GET in the web architecture is somewhat less significant. Whatever the other pros and cons of Web Services arch, it seems better targeted to these application-to-application secure scenarios.

16:13:25 [noah]

VQ: Breaking for lunch.

17:06:17 [DanC_mtg]

Topic: TAG Directions (continued)

17:06:33 [DanC_mtg]

VQ: let's go around and get some input from each on priorities...

17:06:56 [DanC_mtg]

ER: webarch doc is incomplete without semantic web and web services. let's spend some time on that. And let's solve httpRange-14 this week

17:08:06 [DanC_mtg]

DC: the "languages and namespaces" bullet from HT's msg seems important to me; namespaceDocument-8 and such. none of the higher level goals seems all that attractive

17:08:18 [DanC_mtg]

TimBL: ... semantic web and web services ... [missed?]

17:08:56 [DanC_mtg]

NDW: looking at the issues list, I saw 5ish that are related to URIs. Nailing that cluster seems worthwhile

17:09:48 [DanC_mtg]

RF: no particular issues to "grind"... would like to see more "how the semantic web affects Web architecture". Would like to see more about what Web services efforts aim to achieve. [?]

17:10:08 [DanC_mtg]

... would not want to tell them what to do, though.

17:10:56 [DanC_mtg]

NM: (1) to see that the information space continues to grow and thrive

17:11:04 [dorchard]

17:11:49 [DanC_mtg]

... [missed 2 and 3?]

17:12:02 [DanC_mtg]

... want to be sure there's an architecture that all the parts share

17:13:14 [DanC_mtg]

(timbl seems to be composing a table on the whiteboard)

17:13:30 [DanC_mtg]

HT: the issues of state, side-effect, and context seem important.

17:13:43 [DanC_mtg]

... and that connects to user identity/authentication

17:14:16 [DanC_mtg]

HT: httpRange-14 ... I still can't see how that's orthogonal to secondary resources.

17:14:41 [DanC_mtg]

HT: languages and namespaces, as DanC mentioned

17:15:02 [DanC_mtg]

HT: I think we owe the XML community a look at "the entity problem"

17:15:54 [DanC_mtg]

HT: should there be a way of doing what entities do? i.e. refer to large complicated things with small simple names?

17:16:27 [DanC_mtg]

DO: I'd like to see the web figure out how to give more things URIs...

17:16:38 [DanC_mtg]

... if that means dealing with stateful services, then very well...

17:16:45 [DanC_mtg]

... if that stretches "REST", then very well

17:17:06 [DanC_mtg]

DO: let's continue to pay attention to architecture properties, e.g. statefulness, [missed?]

17:17:14 [DanC_mtg]

DO: and extensibility and versioning

17:17:42 [DanC_mtg]

VQ: not sure we need to define the architecture of web services...

17:18:19 [DanC_mtg]

... more interested in extending/specializing the present web archtiecture in a way that's useful for web services and semantic web...

17:18:56 [DanC_mtg]

VQ: it's important to take into account new user interaction mechanisms [?]... peer-to-peer, streaming... integrate those with web architecture

17:20:58 [DanC_mtg]

(I think I have a copy of the list timbl put on the whiteboard in an outliner; can send XHTML version on request)

17:22:28 [DanC_mtg]

(timbl's list has grown some arrows; no longer fits in a hierarchical outline. imagine that ;-)

17:23:52 [DanC_mtg]

(hmm... if WG members are our customers, I wonder about a WBS "what do you want the TAG to do?" survey, seeded by something like this list)

17:24:32 [DanC_mtg]

VQ: so we have a long list now... of course we need to narrow it down...

17:25:52 [DanC_mtg]

... keep in mind that our most visible products are REC-track documents

17:27:43 [DanC_mtg]

As VQ erases vacation calendar from the whiteboard, VQ requests that TAG members send email copies to him

17:38:16 [DanC_mtg]

(HT and TBL discuss httpRange-14 a bit in the context of URI-space.png )

17:39:22 [DanC_mtg]

NM: ... that's one of the reasons we should[?] talk about resources that have URIs but no GET/PUT/POST ...

17:40:58 [DanC_mtg]

DC: I'd like to remove "XML entities"

17:41:00 [DanC_mtg]

HT: then who?

17:41:03 [DanC_mtg]

NDW: XML Core

17:41:04 [DanC_mtg]

DC: +1

17:42:24 [DanC_mtg]

DC: how does this go beyond XML spec into web architecture?

17:42:31 [DanC_mtg]

HT: let me think about that a bit

17:43:49 [Norm]

Dan's list has "~5 issues NDW found", for the record, I was thinking of IRIEverywhere-27, metadataInURI-31, abstractComponentRefs-37, rdfURIMeaning-39, URIGoodPractice-40, DerivedResources-43, endPointRefs-47, and URNsAndRegistries-50

17:44:34 [DanC_mtg]

NM: Ajax changes what a web page is, especially if you do it wrong; google seems to be pretty careful...

17:44:53 [DanC_mtg]

... this "mint me a URI for the current state" design seems good...

17:45:13 [DanC_mtg]

TimBL: note IE allowed javascript to change the address bar; security issue

17:46:10 [DanC_mtg]

NM: something goes bad when content goes into executable "run the program and see what it produces" formats rather than declarative

17:46:25 [DanC_mtg]

DC: quite; the Principle of Least Power is important and underdocumented

17:49:17 [DanC_mtg]

VQ: note new work starting in Web Applications... how do we relate?

17:49:35 [DanC_mtg]

TBL: where there's a WG on something, let's let them do it...

17:49:44 [DanC_mtg]

... but let's be sure they know about the Principle of Least Power

17:51:02 [DanC_mtg]

NM: (1) within W3C, yes, the TAG can help the Web Apps work stay declarative etc, but (2) there's stuff going on outside W3C

17:51:48 [ht]

http://www.w3.org/DesignIssues/Principles.html for Principle of Least Power

17:56:56 [DanC_mtg]

HT: how about putting web services and semantic web under URIs? i.e. perhaps TAG's job is to say how URIs relate to those two

17:57:55 [DanC_mtg]

(DC tries it in the outliner)

17:58:44 [DanC_mtg]

DO: [missed the gist of it]

17:59:33 [DanC_mtg]

NM: misunderstandings between this group and web services practitioners are perhaps not clarified by sticking web services under URIs...

18:01:16 [DanC_mtg]

... one argument I've heard against using URIs is that network effects don't apply; nobody else needs to refer to this thing, for similar reasons that we don't routinely use URIs for "that 3rd http header field"

18:01:35 [dorchard]

DO: much of Web and Web service development is around stateful resources that have a secondary resource identifier, which can be identified by just URIs+ frag-ids, but are also often identified by cookies or WS-A EPRs.

18:02:48 [DanC_mtg]

DO: one of the arguments I've heard for WS-Addressing endpoint references is that it works like cookies: "echo this back to me so that I can dispatch on it"

18:03:33 [timbl]

URIpath?

18:03:40 [DanC_mtg]

... and dispatching based on qnames in XML trees is easier than dispatching on URIs . [?]

18:04:15 [timbl]

DO: I wonder whether we need that URI query langauge for getting stuff out of a URI.

18:05:17 [DanC_mtg]

(in what way is it OK that they're not counting on reuse, timbl?)

18:07:14 [DanC_mtg]

DC: the cases where you don't design for reuse is generally not the Web, though, is it?

18:07:32 [DanC_mtg]

TimBL: right; this isn't the web. This is Web Services, an alternative architecture.

18:10:38 [DanC_mtg]

(scribe hears lots of endpointRefs-NN discussion, but doesn't have the energy to capture much of it until/unless it's more clearly in order)

18:14:07 [DanC_mtg]

DC: put Security 1st? we'd become very popular and unpopular... and it's at least as much QA as architecture; in many cases, the specs are there but not (well) implemented

18:14:21 [DanC_mtg]

NDW: let's not. that'll take all the energy we've got and then some

18:14:27 [DanC_mtg]

ER: [forgot/missed?]

18:14:55 [DanC_mtg]

HT: it should be in [that diagram?] but it's not. why not? [?]

TBL: ... passwords in the clear ...

q+ to ask if we're confident that security will layer cleanly everywhere

18:16:45 [DanC_mtg]

TBL: with webarch v1, we didn't say "here's the web architecture; it's complete." we just elaborated on some places where mistakes had been made often, and where issues had come up a lot. and it was worth doing.

HST thinks pushing on the question of RDDL semantics is a useful way to go

NM: maybe this document should use a different media type... say for RDDL... so that the anchors work out. If we just use a different media type, which doesn't have much subtyping, we lose the fact that it's HTML, and some browsers don't know they can render it, etc.

TimB: 5. This is an element (which is a repr of a function)

Henry: 2[whose representation is [this element you just retrieved]]

20:06:24 [Ed]

Norm: The # refers to a function

Quoting from RFC 3986:

Henry: The machine gets to an acher which is an element of the rddl name space.

20:07:19 [noah]

The fragment identifier component of a URI allows indirect

20:07:19 [noah]

identification of a secondary resource by reference to a primary

20:07:19 [noah]

resource and additional identifying information. The identified

20:07:19 [noah]

secondary resource may be some portion or subset of the primary

20:07:19 [noah]

resource, some view on representations of the primary resource, or

20:07:20 [noah]

some other resource defined or described by those representations. A

20:07:22 [noah]

fragment identifier component is indicated by the presence of a

20:07:24 [noah]

number sign ("#") character and terminated by the end of the URI.

20:07:26 [noah]

fragment = *( pchar / "/" / "?" )

20:07:28 [noah]

The semantics of a fragment identifier are defined by the set of

20:07:30 [noah]

representations that might result from a retrieval action on the

20:07:32 [noah]

primary resource. The fragment's format and resolution is therefore

20:07:34 [noah]

dependent on the media type [RFC2046] of a potentially retrieved

20:07:36 [noah]

representation, even though such a retrieval is only performed if the

20:07:39 [noah]

URI is dereferenced. If no such representation exists, then the

20:07:40 [noah]

semantics of the fragment are considered unknown and are effectively

20:07:42 [noah]

unconstrained. Fragment identifier semantics are independent of the

20:07:44 [noah]

URI scheme and thus cannot be redefined by scheme specifications.

HST wonders what the text/html media type registration actually _says_

20:16:28 [noah]

For documents labeled as 'text/html', [RFC2854] specified that the

20:16:28 [noah]

fragment identifier designates the correspondingly named element,

20:16:28 [noah]

these were identified by either a unique id attribute or a name

20:16:28 [noah]

attribute for some elements. For documents described with the

20:16:28 [noah]

application/xhtml+xml media type, fragment identifiers share the same

20:16:29 [noah]

syntax and semantics with other XML documents, see [XMLMIME], section

20:16:31 [noah]

5.

20:16:39 [DanC_mtg]

(I can't find this bit about frag interpretation in the XHTML spec)

20:17:02 [timbl]

q+ to try Roy's model as a stack

20:17:11 [noah]

http://www.rfc-editor.org/rfc/rfc3236.txt

20:18:43 [noah]

The above is, I think, the media type registration for application/xhtml+xml. It is by the way explaining what rfc2854 has said about text/html. I'm claiming the latter says there is a precedent for anchors sometimes referring to elements.

DanC_mtg, you wanted to ask about crossing levels... suppose I want to make RDF statements about the hypertext document, e.g. revision control stuff ala cvs blame

20:51:05 [DanC_mtg]

hmm... isn't a type one of the components in a schema? ah... I guess not. hmm.

20:54:14 [ht]

We have type definition schema components

20:54:21 [ht]

anything else is sloppy talk

20:54:30 [DanC_mtg]

Hmm... when I brought this namespace doc up, I pretty much expected to go down all these holes... for a little bit, I thought we actually got somewhere. Now I'm not so sure we haven't just re-played this conversation for the N-hundredth time. I'm surely no more sure about what to *do* in the case of the XQuery F&O namespace doc.

20:54:59 [ht]

DanC, give me a simple n3 version of a statement about Tim's car, e.g. that it is Tim's car, please

20:55:08 [Norm]

I have at least one technical question about the F&O namespace doc too that's not at all philosophical

20:55:16 [DanC_mtg]

{ :tcar :owner :tim }.

20:55:19 [DanC_mtg]

or just { tcar owner tim}

20:55:36 [ht]

with URIs? possible?

20:55:42 [ht]

all three of those are URIs?

20:56:05 [DanC_mtg]

yes, they're all URI references, which stand for URIs w.r.t. the relevant base

21:05:05 [Norm]

Hard to tell.

21:06:30 [ht]

21:07:26 [Ed]

I hear versioning is going to join our discussion shortly :)

21:07:37 [ht]

yup

21:07:42 [Norm]

lol

21:14:25 [DanC_mtg]

(hmm... we agreed to stop at 5pm earlier.)

21:14:26 [dorchard]

How about versioning of range-14?

21:16:03 [Norm]

Can we ignore some _known_ 14s instead?

21:17:38 [dorchard]

how about versionable levels of 14?

21:19:14 [DanC_mtg]

somewhat tentatively PROPOSED: to address httpRange-14 by noting a few different levels... a URI can refer to a high-level thing, and "point" to something at a lower level, e.g. an anchor or an element

21:19:50 [timbl]

s/or an element

21:19:50 [DanC_mtg]

... and to say that yes, content negotiation between .html and .rdf works

21:20:05 [timbl]

and mixed namespace stuff works.

21:20:18 [ht]

My stab at saying this is that there are two relations we care about: identification, which relates URIs to things (was 'resources'), and 'pointing', which relates URIs to representations

21:20:36 [timbl]

s/representations/anchors

21:21:31 [DanC_mtg]

RRSAgent, pointer?

21:21:31 [RRSAgent]

See http://www.w3.org/2005/06/14-tagmem-irc#T21-21-31

21:21:36 [DanC_mtg]

RRSAgent, make logs world-access

21:22:19 [timbl]

A URI can *identify* a thing, and also "point to" an anchor.

21:23:31 [timbl]

"points to" is the answer to "how should I represntat this to a user who has followed a hypertext link"?

21:24:00 [ht]

HST just wants a gloss on 'anchor' -- is it fair to say that if I have (a representation of) an information resource, and its media type, I will know what the set of possible anchors is?

21:24:27 [DanC_mtg]

oops... "refer to" was a mistake; I should have said: a URI can identify a high-level thing...

21:24:52 [DanC_mtg]

NM: let's please do continue to work on examples of these

21:26:19 [DanC_mtg]

(is http://www.w3.org/2005/06/13-tag123.html already referred to? if not, it is now)

21:26:23 [timbl]

A subset of information resources have non-trivial anchors.

21:26:44 [ht]

... beyond the anchor which is the whole resource

21:28:49 [Norm]

If ...#tcar is Tim's car and ...#tcar can be an anchor (which is part of a document) and if all documents trivially have an anchor that is the whole document, then ...ncar (no hash) is Norm's car and ...ncar has a representation.

21:29:00 [Norm]

Yes?

21:29:12 [Norm]

But not before dinner :-)
