'd' dropped from the mailing list name 09:29:48 ... the mailing list archive is open to public to read 09:30:27 ... until yesterday only folks who had signed up to the wg could post to the list but it is now open 09:30:39 ... will a wiki help us 09:30:54 ... w3c infrastructure does not formally support wiki's yet 09:31:02 ... but we have expereince in swad-e 09:31:13 ... we can consider whether to use one 09:31:26 ... we do produce formal published documents 09:31:41 ... such documents must have a certain style, should validate etc 09:31:51 ... there is a set of publication guidelines 09:32:04 ... there is a set of best practices for all w3c pages 09:32:21 ... we ahve assistance from the communictions team e.g. marie-claire 09:32:30 ... they are very hard worked 09:33:23 ... new opportunity - we were approached by society for technical communication who offered writers so we might get some help to write the documents 09:33:41 ... we may be a suitable group to take advantage of that opportunity 09:34:36 guus: we will come back to issues around planning, telecons, f2f etc 09:34:44 ... expect to have f2f twice a year 09:34:53 fyi, many of the materials mentioned in Ralph's talk are on the WG homepage too. http://www.w3.org/2001/sw/BestPractices/ 09:34:55 ... get requirments of people on the table 09:35:19 .. this pm we will discuss notion of task force 09:35:34 break for coffee 09:53:33 jacco has joined #swbp 10:09:45 timbl has joined #swbp 10:10:28 Zakim, what is the passcdoe? 10:10:28 I don't understand your question, timbl. 10:10:28 Zakim, what is the passcode? 10:10:28 the conference code is 79273, timbl 10:10:58 +TimBL 10:11:33 marie has joined #swbp 10:12:00 list archive has some input on group priorities: http://lists.w3.org/Archives/Public/public-swbp-wg/2004JanMar/thread.html 10:12:05 (says Guus) 10:12:09 Chris Welty 10:12:24 later... 10:12:33 Aldo 10:12:55 Zakim, who is on the phone? 10:12:55 On the phone I see Tp_iles_a, Deb_Mcguinness, TimBL 10:13:14 areggiori has joined #swbp 10:14:13 Aldo Gangemi, ICST, CNR 10:14:32 The Three Lightening Issues 10:14:39 ivan has joined #swbp 10:14:42 thinking of priorities for semweb ontologies 10:14:46 for final users 10:14:50 1) Learn logic 10:14:52 Thu, 04 Mar 2004 10:14:46 GMT 10:14:56 2) Learn formal logic 10:15:04 3) Learn knowledge acquisiton 10:15:23 given these three reqs 10:15:45 the chance of success is None if thet target is semantic web users 10:16:17 chance is Reasonable, if the expectations turn into requirements for ontology construction tools 10:16:35 chance = 1 (certainty), if ?? unknown 10:16:39 Priotities for best practices 10:16:49 * logic construction patterns (canonical forms) 10:16:58 - tempaltes, examples, familar interfaces 10:17:14 * Ontology design patterns (content skeeltons) 10:17:45 - templates at the content level, step-by-step maieutics and examples 10:17:46 maieutics? 10:17:55 = the techqnique from Socrates 10:18:17 The extraction of knowledge you never knew you had" 10:18:22 libby has joined #swbp 10:18:27 :) 10:18:45 ChrisW - this makes ontology seem like a simple world 10:18:50 Ardo: 10:18:59 * Acquaisition workflow managers (smaret assistants) 10:19:15 - workflow incl maintainance, transformation tools 10:19:27 Thu, 04 Mar 2004 10:19:16 GMT 10:19:35 (above, s/simple world/simple word/) 10:19:43 areggiori has changed the topic to: 10:19:55 Ardo shows an ontology requirements diagram 10:20:28 Maieutics, n.

Resuse of data -- use across applications -- only pays off when you have several applicstions involved. resue of design -- the fact that ontolgy work is about real things rather than programming artifacts -- pays off as you design and especially when you redesign an application. 10:36:23 Dirk, Asemantics - 10:36:41 - semweb tech you see triples at the core, but in the apps you find other things like provenance 10:36:55 - so if you are on best practice side, you may be adding extra elements 10:37:32 - maybe one of the outreach things could be documentating where you practically have to go off the path, in order to build industrial-strength semweb apps 10:38:04 Libby Milller, University of Bristol: 10:38:41 1) examples and tests where appropraite 10:38:44 can be very useful 10:38:52 2) identification of things 10:38:58 in particular people, events 10:39:11 people like to assign uris for people, we've been using the owl:inverseFunctionalProperty 10:39:17 ways to write this down would be useful 10:39:23 3) for newbies, pointers to existing vocabs 10:39:31 how to find them, mechanisms for reusing them and mixing themj 10:39:54 Guus - how suitable is FOAF as a semweb demo app? for convincing outsiders? 10:40:06 LM - seems to convince people qutie well, open 10:40:21 on foaf as a demo: it has nice eye-candy SVG tools. but it gets hash-vs-slash wrong. 10:40:38 LM - people do get it as a compelling app, also 'cos it is about people 10:40:40 [it uses no hash in its namespace which is an architectural problem and a bad example] 10:40:57 danbri - have been trying to explain rdf for years, find it easier for foaf 10:41:05 LM - about things in the world rather than on the web 10:41:08 shawn has joined #swbp 10:41:19 jjc - presentational issue with FOAF, sometimes feels rather geeky 10:41:31 ralph, would you please project http://esw.w3.org/topic/RdfCalendarPresentation when it's my turn? 10:41:50 jjc=Jeremy Carroll, HP 10:42:07 Ivan Herman - 10:42:20 foaf is fun yeah, but what are the big business oriented apps? 10:42:26 this is not one 10:42:46 one I usually refer to is Baby Care (ref to AC meeting in Yokohama) 10:43:06 Guus asks Ivan to talk about this later 10:43:16 [I note that there are already several FOAF-oriented commercial sites, one of which exprts FOAF] 10:43:20 Liddy neville - 10:43:31 separate the general from the specific; foaf is a general class of things 10:43:39 Zakim, mute me 10:43:39 TimBL should now be muted 10:43:53 try to suggest that there is a list of the general to separate from the specific 10:43:56 zakim, mute Deb 10:43:56 Deb_Mcguinness should now be muted 10:44:45 ?, INTAP - 10:45:04 1) intelligent home appliance 10:45:23 2) japanese cultrure reflected tech 10:45:26 Noboru Shimizu (Interoperability Technology Association for Information Processing, Japan) .

From earlier: /me notes that Jeff Bezos from Amazon was in the etech foaf session audience, but didn't get to talk to him 10:47:47 adobe's been implementing semantics on media objects in our projects 10:47:54 products 10:48:02 been working on business use cases 10:48:23 ^- is 1) 10:48:36 2) development of, registration of vocabs to make people's learning curve easier 10:49:03 3) answer why you want to express it in rdf?, isn't xml good enough? 10:49:15 - been asked by 4 groups available, mostly at the database end 10:49:33 - the scope of the group needs to expand a little 10:49:56 Why isn't XML good enough? After long discussion last night, I think the answer may be "RDF solves the mixed namespace problem" (cf. yesterday's plenary discussion) 10:50:06 Chuck outlines detailed workflow and semweb may apply 10:50:15 good to have some of those people participating in the WG 10:50:19 (it solves an interesting part of the namespace mixing problem, anyway) 10:50:22 gk, er...no :) 10:50:45 Dan Brickley, W3C/ILRT: 10:50:49 I guess I don't have a crisp understanding of the mixed namespace problem 10:50:54 Guus: I intend to follow up with you, Chuck Meyers 10:51:04 main rdf specs finished 10:51:06 RDF doesn't *have* a mixing namespace problem...but it doesn't have namespaces 10:51:18 lots of stuff for BPD potentially 10:51:31 lets focus on gatherhing storeis not just use cases 10:51:44 talk to earliy adopters, kr old terms and newcomers 10:51:57 such as if newcomers read stuff and felt stupid, find out what was going non 10:52:00 on 10:52:04 wishlist 10:52:04 Gk: When, really thhe answer is that SemWeb is a more pwerful technology in many ways. But the fact that is has solved the ns mixing problem is a big thing -- in tha XML technologies which don't discuss what thinsg mean are incapable fo solving that problem generically. 10:52:09 1) thesauri on the sw using rdf/owl 10:52:24 2) what you put at a namsespace uri - techniques for useful info behind them - rdf/owl/xjhtml 10:52:28 bijan, sure that's another way of expressing it. But, from yesterday's discussion, XML *does* have some issues with composing documents using different namespaces. 10:52:30 3) [too slow] 10:52:52 (please don't paste the text in. please mail the slides) 10:53:33 if there is a url for slides though, that is good to paste in this log 10:53:42 there is no url, that's the point 10:53:48 gk, it's not an other way of expressing it :) It's expressing something different! 10:54:12 danbri explains thes stuff 10:54:25 And that is why it has solved the namespaec mixing problem. 10:54:30 danbri 2) vocab documentation 10:54:37 .. seems like a job for the TAG 10:54:54 the rest is on the mythical slides 10:55:20 go out see what people have done 10:55:25 3) versioning 10:55:35 vocab versioning 10:55:50 Look, I think it's just an error to say you've solved a problem if you merely redefine it *without* demonstrating that your redefinition meets the needs of the people with the problem 10:56:02 costs of changing, would like to see thoughts on changing vocab and costs 10:56:18 (hmm... can you measure the level of agreement between what a "namespace document" says and what the data files say about those terms? we do a little bit of that in RDF calendar) 10:56:21 Jos De Roo, AGFA-Gevaert 10:56:23 Bijan, you talking about the ns mixing problem? 10:56:23 OK how to rescue that from powerpoint? maybe I'll cut and paste... 10:56:26 Such moves tend to irritate the people with the problem. Rightly I think. 10:56:27 pointer http://lists.w3.org/Archives/Public/public-swbp-wg/2004JanMar/0006.html 10:56:30 timbl, yes 10:56:44 danbri, pls mail to www-archive or swbp 10:56:57 JdR - 10:57:18 not necessary to re-invent things, taking 10s of years 10:57:34 working with helping work with when the are overlapping 10:57:48 connecting them, a case with interoperability 10:57:51 danbri slides: http://lists.w3.org/Archives/Public/www-archive/2004Mar/0017.html 10:58:15 2) test results 10:58:19 I mean, in some important sense, XML can solve the mixed namespace problem the same way RDF does: Don't use namespaces! Done! :) 10:58:26 an extension or an ontology for a more clafieid output 10:58:45 3) 10:59:06 pracitcal use case 10:59:20 believe it should be hands on, bottom-up 10:59:35 semantic web is to some extent webizing real world problems 10:59:39 Guus - 10:59:57 interested in formal pub of medical vocabularies? 11:00:03 RDF, or OWL at least, *has* some vocabulary mixing problems, e.g., combining two owl lite documents can produce an owl full...Surprise! 11:00:22 discussion of public/pay for medical vocabs 11:00:24 bijan, I think that needs more explanation, just as my terse assertion also does. I'm reluctant to continue this debate here, but happy to engage later. 11:00:24 [The namespace mixing problem: When you have two independently designed XML langauges each with define semantcis, how do you define the semantics of a document which uses a a mixture of the two langauges? RDF solution: constrain the XML langauges to be RDF. The semantics of the mixed langauge document is the set of triples defined by RDF] 11:00:39 Guus - could discuss later today 11:01:06 timbl, pifft. That's no solution. What are the semantics of a mixed namespace document in xml?
