It had history with Tim Bray, then Paul Cotton, both now gone. 17:12:31 NW: I've somewhat lost track of where it stands, but I'll take the lead if we figure out what we want to do. 17:13:07 NW: The AC asked the TAG to produce a rec-track document, presumably based on RDDL. 17:13:12 VQ: Do we have a draft? 17:13:13 NW: No. 17:13:48 NW: I'm willing to produce if asked to do so, either based on RDDL 1.0 or something else. What do we want to do. 17:13:49 Would prefer 1.0 17:13:57 s/do./do?/ 17:14:36 NW: ht has pointed out use of RDDL 1.0 in some W3C specs. Microsoft is also deploying? 17:14:51 TBL: Are you saying TAG should produce a Rec? 17:14:56 NW: AC asked us to. 17:15:23 TBL: GRDDL affects this, no? 17:15:32 HT: Solves a different problem. 17:15:36 TBL: Why? 17:16:08 HT: RDDL solves, what should you do specifically with namespaces. GRDDL is about: "I've got a doc that serves two purposes (1) to be an XML document and (2) how to harvest metadata" 17:16:38 TBL: GRDDL allows you to extract (RDF?) information from something that is not in RDF form. 17:17:05 NW: One of the objections to earlier Namespace formats was that they were not in RDF and should have been. GRDDL takes the heat off of that. 17:17:17 HT: Some of the problems we're solving don't need all the RDF mechanism. 17:17:30 TBL: Yes, but for the many namespaces built for RDF it makes great sense. 17:17:50 TBL: For a semantic web language, then OWL should be the language of the namespace document. 17:18:04 HT: Historically, we decided early that there was no single thing you wanted to say about a namespace. 17:18:23 HT: Among the many such things is what the RDF schema is, what the XML Schema is for the serialization. 17:19:04 TBL: I understand. I think you need to divide the cases. XML Schema makes no sense for RDF vocabularies. 17:19:40 HT: But with GRDDL it does make sense. It gives me license to author in colloquial XML a document that is known to contain RDF statements. 17:19:49 HT: For such a document, all of that makes sense. 17:20:04 Norm has joined #tagmem 17:20:13 TBL: That makes sense, except that when I extract the RDF information I would not expect the extracted doc to be in the same namespace. 17:20:14 zakim, mute me 17:20:14 norm should now be muted 17:20:17 HT: OK, makes sense. 17:20:45 zakim, who's here? 17:20:45 On the phone I see TimBL, ??P11, noah, Vincent, norm (muted), Roy_Fielding, Ht 17:20:47 On IRC I see Norm, timbl, Roy, noah, RRSAgent, Ed, Zakim, Vincent, ht, DanC 17:20:57 HT: Still, my point is that the original RDDL was based on the presumption was that there would be more than one document of interest, and that it would contain pointers to one or more things as necessary. 17:21:13 TBL: Well, only if we say that this is only for non-semantic web namespaces. 17:21:33 zakim, unmute me 17:21:33 norm should no longer be muted 17:21:44 HT: I'm less convinced than you that the differences matter, but I can easily live with a statement that at least for now, the RDDL approach is aimed at non-semantic web namespaces. 17:21:52 zakim, who's talking? 17:21:55 Roy has joined #tagmem 17:21:59 HT: Information please: does OWL say use it as a namespaces doc? 17:22:03 Norm, listening for 10 seconds I heard sound from the following: TimBL (71%), ??P11 (43%), Vincent (19%) 17:22:21 q? 17:22:26 q+ 17:22:27 TBL: No, but the TAG did some sort of best practices note (can't fine right now) says do that, and I think it's common practice. 17:23:01 HT: OK, so finding might say: if (isSementicWeb) then {use owl} else {use RDDL} 17:23:27 NW: I'm not convinced that using RDDL for all is bad, with the RDDL pointing to the OWL. I want human readable documentation, etc. 17:23:47 NW: I'm thinking of Ed Dumbill's work on software project descriptions. It's both RDF and not. 17:23:59 DOAP 17:24:03 NW: I don't totally disagree with Tim, but I'm not totally convinced either. 17:24:10 TBL: what's he really done? 17:24:12 pointer to RDDL in minutes? 17:24:17 http://usefulinc.com/doap 17:24:31 NW: A constrained RDF that's usable as XML. 17:24:32 http://www.rddl.org/ 17:24:38 TBL: right, that's the tricky case 17:25:40 TBL: specifically because there's an issue of whether the fragid identifies the concept or the markup 17:25:50 HT: argh, not httpRange-14! 17:26:17 NRM: No, smaller than httpRange-14. We need to ask what's the media type in this case, and what answer is given to Tim's question about fragids. 17:26:19 http://www.w3.org/TR/2004/REC-webarch-20041215/#namespace-document 17:26:21 ack Roy 17:27:14 q+ ht 17:27:20 RF: We've been around this before. Key question is: what's the requirement for the document? I think we had consensus on one thing, which is that the key requirement is that it be human readable. 17:27:28 Roy is right, we did come to consensus on that point 17:27:33 TBL: I'm not sure we said that. For some cases, machine readiable is important. 17:27:42 s/readiable/readable/ 17:28:07 I don't think we had a consensus that human readable was primary. Tim Bray said so strongly. I am prepared to defend strongly the semantic web use of OWL and RDF in general. 17:28:18 RF: I mostly don't want to go around same ground again. Ideally, it's useful for human purposes and machine readable as necessary. 17:29:25 TBL: We have a current suite of specs that tell a semantic web agent how to go out and find semantic web information. This would require a new spec and engineering into future software. Is this a good thing to require for agents? 17:29:35 ack ht 17:29:38 TBL: In fact, you can use a stylesheet to make an owl doc human readable 17:29:50 HT: We did this for W3C XML schema 17:30:07 If the cost of the redirect is too expensive, then the cost of the retreival is probably too expensive too. 17:30:19 HT: The rec was written to allow you to implement indirection through things like namespace documents. Most implementations do the right thing when a RDDL doc comes back. 17:30:45 HT: This is a relevant precedent. It was easy and lightweight. About 10 lines of code in the validators I built. 17:31:11 TBL: Most of this software has no XML processing software, except for limited purposes. 17:31:23 RF: They're not extensible for new media types. 17:31:34 s/./?/ 17:31:36 TBL: There's no XML schema processing in the RDF processors. 17:32:17 q? 17:32:23 HT: You've misunderstood. I'm only drawing a parallel. I'm pointing out that the fact that it was easy to add to XML schema processors suggests it will be equally easy to add such indirection to RDF processors. 17:33:08 TBL: Adding something simple to an existing system to something that's currently simple and complete results in a kind of complication. 17:34:07 q+ to ask how sem. web namespaces are the same and different from others 17:34:58 TBL: e.g., using different DTD syntax for XML complicated everything 17:35:45 TBL: Even using the XML stuff for RDF was a complication, but it would be good to hold the line there. OWL is in RDF, so we can get into that world quite quickly and cleanly. 17:35:56 Norm has joined #tagmem 17:36:12 ack noah 17:36:12 noah, you wanted to ask how sem. web namespaces are the same and different from others 17:36:12 q+ to ask if there are any examples of such an OWL namespace description to look at 17:39:03 q? 17:39:29 ack Roy 17:39:29 Roy, you wanted to ask if there are any examples of such an OWL namespace description to look at 17:39:35 I always thought it was the XSL WG's requirement that produced Namespaces. . . 17:40:07 NRM: Tim tells us that sem. web. is a clean closed consistent world, but some of the complication comes from the fact that it shares a namespace mechanism with a wider XML world. 17:40:18 DanC, are you happy with the XRI response? 17:40:25 http://localhost:8123/2005/04/26/atom.rdf 17:40:26 http://norman.walsh.name/2005/04/26/atom.rdf 17:40:40 NRM: This allows a nice "pun", in which the serialization of an RDF namespace is the corresponding (same) XML namespace. We also can reference XML datatypes. 17:40:57 I think so, ht. the one I reviewed and commented on was pretty close, and I assume the subsequent edits remain in that neighborhood 17:41:35 NRM: This will pop up on one side or the other: if we want the sem web side to be clean and consistent, then the story about namespaces as a whole gets more complicated. If we have a uniform story about all namespaces (e.g. RDDL), then the sem. web side gets a bit more complicated. Take your choice. 17:41:53 NW: Well, if we need a special case for something like semantic web, I'm not sure it's worth doing at all. 17:41:53 I have :) 17:42:01 (taken my choice) 17:42:31 VQ: Time's about up. I had hoped we could decide about publishing something based on RDDL? Looks like 'no'. 17:42:49 VQ: Let me ask the original question again: is there anything we could publish as a heartbeat from the WG? 17:42:56 TBL: Note or working draft? 17:43:11 VQ: Working draft would make requirement heartbeat. Do you have any in mind, Tim? 17:43:20 +DanC 17:43:20 TBL: No. Norm said he would write something. 17:43:31 Dan appears to have joined the call. 17:44:02 NW: I'm reluctant to write draft without consensus on what high level approach to attempt. 17:44:42 q+ to say _if_ we are happy with RDDL 1.0, _then_ we can do a NOTE real quick 17:44:55 ack DanC 17:44:55 TBL: We're being lured into grabbing an answer that's lying around. This sounds like a job that's more suited to a WG that would focus on it more seriously. When we started this, RDDL looked pretty well baked. 17:45:45 DC: We have to publish something or close the group, or get permission from the director to continue anyway. We don't have to decide what it is today. 17:46:30 VQ: My understanding is RDDL is not ready for pub soon, and I'm asking if we have anything else to publish. 17:46:58 TBL: What about asking Norm to write a finding discussing the RDDL/OWL questions in relation to namespaces. 17:47:12 s/namespaces./namespaces?/ 17:47:28 (pls let the record show we're discussing issue namespaceDocument-8, not just the heartbeat publishing requirement) 17:47:37 NW: I could pull together a short finding talking about earlier RDDL work, and today's discussion. 17:47:42 TBL: Would OWL be in there? 17:47:58 NW: Yes, if it belongs at all. I know where I'd like it to come out, but this finding is where it all belongs. 17:48:07 NW: Will try to do something this week. 17:48:09 q- ht 17:48:15 q+ ht 17:48:53 DC: You're going to hit all kinds of fun stuff, such as the fact that rddl.org is a non-w3c basis for a namespace name. 17:49:49 VQ: what's on the agenda was dan's proposal to publish something based on RDDL. 17:49:55 DC: that was an aside. 17:50:57 HT: I could possibly move along the finding on issue 50, which would give us something to publish. 17:51:07 (what HT is drafting on issue 50... doing that as a /TR/ publication would be different from the way we've done findings in the past, but not a bad idea) 17:51:25 VQ: That would give us a first WD 17:51:37 HT: Right, that's what I meant. 17:51:49 HT: Do findings count as tech reports. 17:52:02 s/tech reports/heartbeats/ 17:52:06 DC: No 17:52:17 HT: We need discussion on that meta topic. 17:52:46 HT: We are not working primarily in a Rec mode, and should not do backflips to fit into a process not tuned to our needs. 17:52:55 VQ: Yes, we should discuss that. 17:52:59 TBL: I agree with HT 17:53:03 (I don't mind changing the rules. My job as team contact is to enforce them or change them. I'm happy to do either.) 17:53:18 NRM: At next meeting? 17:53:21 VQ: yes. 17:53:57 VQ: Henry, can you make progress in issue 50 anyway? 17:54:03 HT: Yes, I intend to try. 17:54:20 Topic: Planning next F2F meeting in Boston 17:54:59 VQ: We started some discussion about what we should do as next technical document, that we should prepare in advance, but should do that mainly face to face. 17:54:59 q+ to suggest we have a F2F goal for a REC track webarch volume 2 that contains only an outline 17:55:04 This is a reminder to start that discussion. 17:55:13 s/This/VQ: This/ 17:55:24 VQ: Ed, was there something else you wanted to ask? 17:55:42 ED: Partly travel plans, partly wanting to focus on issues. 17:56:44 VQ; Meeting will start morning of June 14.
