The purpose of those messages was to establish what we should put in the arch doc. 20:12:17 RF: If TBL wants to describe the Web as everything the W3C is doing, we have to write another document. We need to write a model that describes it all. 20:12:37 RF: The REST model does not describe the SemWeb architecture. 20:13:19 q+ 20:13:20 RF: The reason we have to make a choice: I can describe the system that exists without talking about anything in the future (by looking at implementations). 20:13:28 ack Roy 20:13:48 RF: Whether we want to talk about the future will affect our description. 20:13:57 DO: There is similar discussion going on in Web Services area. 20:13:59 q? 20:14:14 but if there are no implementations in that area, isn't it premature to try and abstract out their properties? 20:14:53 [Agreement to talk about "What should go in the arch doc" at the ftf meeting.] 20:15:33 ack TBray 20:15:52 PC: I think it's important that at our ftf, we talk about www-tag and perhaps a need to organize threads. 20:16:31 SW: We shan't discuss httpRange-14 today; will not be on agenda any time soon. 20:16:34 =========================================== 20:16:51 ah; ftf agenda linked from today's telcon agenda 20:17:35 Mon, 27 Jan 2003 18:14:47 -0000 20:17:35 http://lists.w3.org/Archives/Member/tag/2003Jan/0071.html 20:17:45 F2F Planning: Agenda proposal and Issue strawpoll. 20:18:27 SW: I will send the agenda by COB Weds. 20:18:38 --------------------- 20:18:41 TAG at the tech plenary 20:19:01 DO: Tech plenary planning committee has met. 20:19:05 DO: See msg from PC to tag 20:19:10 http://lists.w3.org/Archives/Member/tag/2003Jan/0069.html 20:19:25 "short" and "5 segments" don't both fit in my brain at the same time 20:19:39 q+ 20:20:59 ack Chris 20:21:17 CL: Good idea to pick top three issues and get input.

Designers of protocols should invest time in understanding the REST 20:32:33 paradigm and consider the role to which its principles should guide 20:32:33 their design: 20:32:33 - statelessness 20:32:33 - clear assignment of roles to parties 20:32:35 - flat addrss space 20:32:39 - limited uniform set of verbs 20:33:20 yes, agreed 20:33:47 ack DanCon 20:33:48 DanCon, you wanted to ask for 4 corners around REST 20:33:56 DC: Are these the top four things for REST? 20:33:58 q+ 20:34:43 RF: "Uniform address space" 20:35:19 DC: I have no objection to this, but would rather explain how to do a Web page / how not to. 20:35:28 DC: I'd be willing to write something up. 20:35:35 ACTION DC write two pages on correct and incorrect application of REST to an actual web page design 20:35:45 (I was talking about a finding... webarch editor to steal as much/little text as he likes) 20:35:47 or a web service 20:36:12 agree with Roy s/flat/uniform/ 20:36:25 note to self: OpenGIS mapping service is a *great* example of a straightforward "uniform address space" service 20:36:26 q? 20:37:20 DO: I'm writing something in Web Services area that's related. 20:37:32 DO: I'd have to publish this info.... 20:38:34 DO: My goal is different - someone who believes in REST can say "this is how I would build a REST-based Web service" and someone more interested in RPC could do things according to that style. 20:39:21 Action DO: Please send writings to tag@w3.org. DO grants DC license to cut and paste and put into DC writing. 20:40:34 TB: Per our charter, please send info to www-tag. 20:41:03 RF: One reason is that we are talking about WS Arch.... 20:41:17 TB: Ok, but I'll keep pushing for www-tag. 20:41:32 Resolved: Accept CP9 with s/flat/uniform. 20:41:34 ===== 20:41:39 CP10. Agents which receive a resource representation accompanied by an 20:41:39 Internet Media Type MUST interpret the representation according to the 20:41:39 semantics of that Media Type and other header information. Servers 20:41:39 which generate representations MUST not generate Media Types and other 20:41:39 header information (for example charsets) unless there is certainty that 20:41:41 the headers are correct. 20:42:14 q? 20:42:16 q+ 20:42:19 q+ 20:42:35 CL: Yeah to CP10 20:42:50 +1 to add this as is 20:42:50 ack Ian 20:42:54 See finding 20:42:58 http://www.w3.org/2001/tag/2002/0129-mime 20:43:18 ack Chris 20:43:21 ack Chris 20:43:42 http://www.w3.org/2001/tag/2002/0129-mime 20:43:48 Internet Media Type registration, consistency of use 20:43:51 q+ to ask Paul C if he is really sure 20:43:57 "The architecture of the Web depends on applications making dispatching and security decisions for resources based on their Internet Media Types and other MIME headers. It is a serious error for the response body to be inconsistent with the assertions made about it by the MIME headers. Web software SHOULD NOT attempt to recover from such errors by guessing, but SHOULD report the error to the user to allow intelligent corrective action." 20:44:38 CL: I like the more general second sentence of CP10 (compared to findnig). 20:44:43 CL: I can elaborate this; and give examples. 20:44:49 I can elaborate this no problem 20:45:10 DC: I prefer what we have in the finding. wget and link checkers don't pay attention to the mime type, and they're still correct. 20:45:41 q+ 20:45:45 they are not, arguably correct 20:45:48 ack DanCon 20:45:49 DanCon, you wanted to wonder about clients like WGET that totally ignore MIME types, in a way that's good. 20:45:54 ack Dan 20:46:04 ack Chris 20:46:05 Chris, you wanted to ask Paul C if he is really sure 20:46:36 q+ 20:46:38 DanC: ... and so the way it's phrased here in CP10 http://lists.w3.org/Archives/Public/www-tag/2002Nov/0107.html doesn't appeal to me. 20:47:10 ack Ian 20:47:25 IJ: I think there is an ok behavior where the tool says "I'm doing something different." This is different than a user agent doing something and hiding it's incorrect behavior. 20:47:36 TB: I support moving finding info into arch doc. 20:47:51 ack TBray 20:47:53 TB: I think we need to say more about "Servers 20:47:53 which generate representations MUST not generate Media Types and other 20:47:53 header information (for example charsets) unless there is certainty that 20:47:53 the headers are correct." in arch doc. 20:48:36 RF: One slight problem - because of some charset interpreting errors in some browsers, often the charset is explicitly given in the doc itself to prevent a cross-site scripting security problem. 20:48:49 TB: If you are sending well-formed XML, it knows what charset it's in. 20:49:27 TB: It's almost always wrong to say what the charset is (and you could get it wrong) 20:49:33 I understand this and can write it in the arch doc 20:49:41 TB: Don't serve as text/xml; transcoders can possibly get it wrong. 20:49:53 Action CL: Include this in arch doc. 20:50:26 s/Include/Draft language. 20:51:39 Action CL: Take language from internet media type registration, propose for arch doc, include sentiment of TB's second sentence from CP10. 20:51:40 === 20:51:57 CP11. Designers of protocols should give serious consideration to 20:51:57 avoiding such design activities in favor of existing well-established 20:51:57 protocols such as HTTP that fit well into REST. 20:52:17 TB: Another way to say this is : Avoid designing new protocols if you can accomplish what you want with HTTP 20:52:58 DC: I think that TBL has an old action to build a table saying: what patterns would imply good protocols. 20:53:04 s/good/appropriate 20:53:10 TB, IJ: We withdrew that. 20:53:14 [That action] 20:53:30 TB: This is a statement worth making; people should think about using HTTP before running off to design a new protocol. 20:53:43 DO: What are the criteria for using/not using? 20:53:53 TB: That's a larger question that may be worth working on. 20:53:59 DC: "In the Web context" is vague to me. 20:54:12 DC: The IETF practice on record is "Don't use HTTP except for hypertext." 20:54:18 DC: Handwaving won't help us here. 20:54:28 s/IETF practice/IETF best practice/ 20:55:24 TB: I have not understood why WebDev was needed as another protocol. 20:55:33 RF: It's written as an extension to HTTP. 20:55:37 DC: It runs on port 80. 20:55:44 DC: My examples are POP and SMTP. 20:56:22 Action TB: Develop CP11 more. 20:56:32 DC: I suggest describing GET/PUT/POST in different paras. 20:56:55 q? 20:56:58 q+ 20:57:23 ... describing GET/PUT/POST in a para each, then say "if your app looks like that, use HTTP". 20:57:42 TB: If your protocol needs a notion of a temporally extended session, then HTTP won't help you. 20:57:49 DO: Why would you need one of those? 20:57:57 [Rhetorical] 20:58:09 DO: You'll need to include some examples. 20:58:47 ====== 20:58:55 # IRIEverywhere-27 20:58:58 http://www.w3.org/2001/tag/ilist#IRIEverywhere-27 20:59:06 CL: IJ and I discussed this last week. 20:59:12 CL: We drew up some text. 20:59:18 q? 20:59:21 ack Ian 20:59:29 CL: Text based on input from Martin. 21:01:13 DC: Value of treating e and E as equivalent is a huge cost. What actual value do you get? 21:01:25 CL: Actual value is that both are equivalent to the same character. 21:01:37 TB: Lots of software is already treating %7e and %7E as the same. 21:01:38 that they are equivalent to the *actual character* represented 21:01:47 uri spec is way fuzzy on this 21:01:53 actual practice is that they are the same 21:02:21 TB: Per 2396, I think Web robots are in their rights; lots of Web robots do this. 21:02:24 RF: Yes, that's my understanding. 21:02:32 PC: Chris, could you explain impact? 21:02:35 q+ 21:02:46 I think it's straightforward to read the URI spec as saying that http://a/%7E and http://a/%7e are distinct URIs, and may or may not refer to the same resource. 21:02:58 roy, you think otherwise? 21:03:10 I think otherwise 21:03:18 I read it the same as Dan :-( 21:03:27 CL: There is a bigger effect on IRI spec and suggestions for RFC2396. 21:03:57 sigh; each of those URIs is a sequence of 12 characters. they differ in their 12th character. hence they're different URIs. RFC2396 says otherwise? 21:03:59 this has more effect on IRI comparison (which is done by transformation to URI and then comparing) 21:04:16 Action CL: Please propose text IJ and CL worked on to www-tag (flipping the ACL). 21:04:20 %7e is one character -- three octets 21:04:27 it means that the *actual kanji* and the sequence of hexifyied octets compare to the same 21:04:37 which helps in roundtripping a very great deal 21:04:57 oops one octet -- char[3] 21:05:05 "%7e" is *one* character??? 21:05:17 "character" is defined in spec 21:05:18 was ignoring IRC... yes, lots of software will decide those two URIs are the same in their cache 21:05:26 no, %7e is one octet 21:05:26 q? 21:05:30 ack DanCon 21:05:31 DanCon, you wanted to suggest the value of having %7E specified to be equivalent to %7e is purely aesthetic, and not *nearly* worth the cost. 21:05:32 ack Ian 21:05:34 ====== 21:05:39 # binaryXML-30 21:05:42 hence *sequence of * 21:05:45 q+ 21:05:50 http://www.w3.org/2001/tag/ilist#binaryXML-30 21:05:57 # 21:05:57 1.

Some requirements are fairly contradictory with each other. 21:12:22 SW: We'll talk about this again in a week. 21:12:58 SW: Rather, ftf meeting is likely next time. 21:13:01 ==== 21:13:05 # xmlProfiles-29 21:13:11 http://www.w3.org/2001/tag/ilist#xmlProfiles-29 21:13:21 TB: Norm's draft: 21:13:25 http://lists.w3.org/Archives/Public/www-tag/2003Jan/0178.html 21:13:42 TB: Was there much disagreement about this? 21:14:19 DO: My pushback was attribution; I don't think there's consensus in the TAG yet. NW wrote his note as NW's position, not TAG position. 21:14:50 DC: I expect that NW will integrate feedback on his position. 21:15:02 DC: At the last meeting, we agreed to comment on NW's text. 21:15:32 http://lists.w3.org/Archives/Member/tag/2003Jan/0025.html 21:16:09 TB: I don't think we have a TAG position without further discussion of NW's draft. 21:16:44 Orchard hasn't responded in substance, has he? he only objected on process grounds. i.e. he hasn't sent his technical position/argument, did he? 21:17:05 NW: I think that there are at least 3 or 4 people who could live with xml:id. 21:17:07 s/NW/DO 21:17:09 q? 21:18:00 TB: I thought we were trying to write a note for the AC on a way to proceed. 21:18:22 TB: My sense is that we pretty much agree with NW's draft except for the xml:id part. 21:18:55 PC: I thought I saw public pushback on having profiles at all. 21:20:07 http://lists.w3.org/Archives/Public/www-tag/2003Jan/0191.html 21:20:31 See also: http://lists.w3.org/Archives/Public/www-tag/2003Jan/0217.html 21:20:59 TB: Mostly I see questions about SOAP and PIs. 21:22:25 TB: We could change "I 21:22:25 feels strongly that it would be a mistake to introduce a single 21:22:25 new feature, or a single change of any sort that would not be 21:22:25 completely compatible with XML 1.1, in the work that subsets XML." 21:22:25 to 21:22:30 "The question remains open..." 21:22:35 DC: Seconded. 21:22:50 TB summarizes NW's proposal: 21:22:55 "In short, it appears that a new recommendation-track document that 21:22:56 defines a subset of XML 1.1 should be developed: 21:22:56 * The subset must be backwards compatible with XML 1.1. 21:22:56 * The subset must define a language that excludes DTD declarations 21:22:56 How the new recommendation is constructed we leave to the editorial 21:22:57 discretion of the group that undertakes it. 21:22:58 " 21:23:08 CL: That would mean that you cannot have xml:id; that's not in xml 1.1. 21:23:19 TB: 1.1 processors would not know what it means, but wouldn't have any problems with it. 21:23:25 SW: I'd like NW to concur with this. 21:23:34 DC: I'm happy for him to do that after the fact. 21:23:47 TB: My proposal is to ack that NW feels this way. 21:24:10 sorry, David 21:24:26 DO: One possibility is to ask the AC what they think; another is to hammer this out further. 21:24:29 q+ 21:24:43 ack TBray 21:25:05 TB: I think it's cost effective for us to tell the world that we think that there should be an xml 1.1. 21:26:15 http://lists.w3.org/Archives/Public/www-tag/2003Jan/0212.html 21:26:25 did I say 1.2? 21:26:42 no I don't mean to say 1.2 21:26:51 Is there an xml 1.1? 21:26:59 Because I wrote 1.1 earlier, perhaps instead of 1.0.... 21:27:19 DC: WRiting to the AC is logistically awkward.
