"planning" is a strong word, but yes, I'm hoping. 16:13:49 e.g. if you wanted to suppliment the meeting agenda with a transcription into calendar-rdf, that would be cool ;-) 16:13:56 neat 16:14:06 I was just going to say that I would help... 16:14:20 today's meeting agenda? 16:14:27 yes, today's 16:14:38 i'll have a look 16:28:13 hi libby; DanC, I just released again I got times wrong; 15:00 EST = 20:00 UTC - doh! 16:28:40 I checked with http://www.timezoneconverter.com/cgi-bin/tzc.tzc 16:29:12 yeah. www.dateandtime.com is quite good too 16:38:51 that site seems like a very general directory 16:45:26 hmm... no webont intro from Jeremy Carroll 16:46:02 he's not been well recently, and on holiday before that 16:48:43 ok... I'll take that as regrets for today's telcon. 17:32:37 hmm... there are a few typos in the WebOnt WG nominations.... 17:32:46 one got familyName/givenName mixed up... 17:32:52 one got Orbst confused with Obrst 17:34:52 kerpow! amaya crashed... 17:35:22 film at 11 :) 17:46:36 yikes... 40 WebOnt WG members. 17:47:02 maybe 41 or 42 17:58:32 JHendler has joined #WEBONT 17:58:53 * JHendler waves to Dan 17:59:00 hi. 17:59:08 any reason for choice of openprojects instead of w3c for irc? 17:59:09 DanC: you can automate that; see /msg chanserv help 17:59:12 I'm reconciling all the various bits of data about WebOnt WG membership. 17:59:40 er... I thought about that, jim... 17:59:58 I dunno if dajobe's offer to log extends ot irc.w3.org 18:00:03 and #rdfig is nearby 18:00:06 DC: I've now heard from all but three people Breen, Kravtsova, Venigalla 18:00:11 DanC: makes no difference to me 18:00:35 In the end, I sorta flipped a coin. 18:00:48 It's okay with me, was just curious 18:01:09 I'm not sure mike dean is subscribed to the mailing list. 18:01:51 his web site access account isn't associated with any groups, so the SQL select that builds the mailing list doesn't catch him. or something. 18:02:49 there's mail from him on webont, so something must be working 18:03:08 have you seen the wg-members-on-the-planet, JimH? it's coming slowly. 18:04:19 I've got 3 independent source of "who's in the WG?": the /2001/sw/WebOnt/ web page, the w3t-semweb-review archive, and the mailing list database. 18:04:26 not to mention random email. 18:04:34 haven't seen it - did you send a pointer (I haven't got to today's email yet) 18:04:54 I sent a pointer, but it was fairly buried. 18:04:57 I've been assuming w3t was definitive and sending things there. 18:05:17 map: http://www.w3.org/2001/sw/WebOnt/webont-world.png 18:05:31 I still can't get access to the mailing list DB (even though chairs are supposed to - no answer from sysreq on it yet) 18:05:54 I sent you an update on that. news is not good. 18:06:48 xplanet seems buggy; it sorta drops labels or something. 18:07:12 ahh, I see it - okay, let's you do all the work :-> Meanwhile, none of my browsers have a png plugin - you know what is standard way to look at them? 18:08:09 ugh... your desktop isn't PNG-happy? 18:08:09 never mind, it is only IE that was braindead - found a netscape plugin 18:08:32 I thought I was the last person on the planet to upgrade to PNG-happy stuff. 18:10:13 the world looks good - need a zoom feature :-> (also, we have a Japanese member - shimizu, he'll be hard to see) 18:11:11 yes, rotate/zoom is needed. RDF->VRML, anyone? 18:12:14 Peter PS reports trouble connecting... 18:12:58 I had problems with openprojedcts when I was behind DARPA firewall - some sort of address forwarding issue 18:13:49 got them to fix it by giving the sysadmins the actual IP address. Not sure if that is Peter's prob. 18:14:55 been working on a small ontology for webont members, was trying to decide whether to link it to your swap/pim/contact stuff 18:15:39 I suggest you make it clear to the telcon participants that the IRC channel is an optional suppliment; mostly for use by the chair/scribe. 18:16:48 by the way, JimH, your use of N3 was sorta goofy... the bit you gave didn't have prefix info etc. it's not machine-convertable to RDF/xml 18:16:50 OK, can explain this as one of my administrivia announcements. 18:17:44 yes, I know - said so in the message - I was just trying to give folks a pointer to N3, and didn't want to wait until I could find all the appropriate namespace tags 18:18:41 you said so in your message? 18:18:43 * DanC re-reads 18:18:46 I don't see it. 18:18:50 I'm fully convinced that many ontologies are going to want to refer to thing in other ontologies (permitted by the D+O language, but not in the Peter/Ian thinking) and want my 18:18:54 new ontology to reflect that 18:19:59 pfps has joined #webont 18:20:15 Hi Peter. Any idea what the problem was or how you fixed it? 18:21:06 you're right Dan - apologies - it is in the file I cut/pasted from, I just missed a line 18:21:19 No idea. I did change from 60s to 120s timeout. You might want to send email concerning the long answer times for openprojects. 18:21:35 Missing line is "@@ add prefix info - no time now" 18:21:44 howdy peter. 18:22:26 *@*@* semi-broken software!! This took too long to set up. 18:23:07 you might want to try irc.us.openprojects.net to ensure a US server rather than a possible one outside USA 18:23:16 yes, software is broken all over the place. But on the other hand, you're chatting real-time around the planet. 18:30:25 * DanC goes back to slogging thru airport data... 18:31:54 pfps has quit 18:35:43 pfps has joined #webont 18:41:14 las has joined #webont 18:43:47 http://ilrt.org/discovery/2001/10/cal-drafts/webont/telecon2001-11-12.rdf 18:44:01 ... is an agenda in rdf 18:44:13 but I had to make rather a lot of arbirary decisions 18:44:46 and I've used yet another schema 18:49:42 i'm not sure how to represent one event being part of another, nor whether/how to say one event follws another (maybe container...) 18:55:18 the cyc time ontology has all that stuff, libby 18:55:48 hmm... that telcon agenda is much more fine-grain than I was thinking; I was just thinking of one 1-hour event. 18:56:10 ah...can do that... 18:56:27 cyc - i'll have a look 18:56:57 by the way... 18:56:57 18:56:57 18:56:57 18:56:57 The agenda for the first WebOnt 18:56:58 Telecon 2001-11-12 18:57:00 18:57:12 that summary should just be "first WebOnt Telcon", right? 18:57:21 i.e. the event is the telcon, not the ageinda. 18:57:24 agenda. 18:59:39 yep 18:59:51 hmm, here's a D+O question - if we want to use some of CYC (including the whole ontology is a major commitment) is that okay?? 19:00:29 okay in what sense? using their terms doesn't commit us to anything. 19:00:33 I just use pointers to particular classes/etc., but the documentation is mum on whether that is correct or not... 19:00:40 changed it to a simpler version,kept full one as ls 19:00:42 las has quit 19:00:51 Ahh, if you copy it to your page, that's fine - I want to say 19:00:54 telecon-full2001-11-12.rdf 19:00:58 if you want to commit to some cyc axioms, you can use daml:imports 19:01:06 hendler:foo a cyc:person; 19:01:24 what would I daml:imports.. 19:02:06 and does it mean I must "agree" with everything cyc says about people... 19:02:09 you'd daml:imports whatever files cyc provides that you agree with.... 19:02:41 ... I was thinking they exported their stuff in little RDF chunks, but I was confused... they provide HTML chunks, but just one big RDF dump. 19:02:58 but right now CYC only provides a 40k file of everything it believes in, and I don't want to have to check through everything in it to make sure I agree before inserting it into my ontology.... 19:03:28 no, just writing "hendler:foo a cyc:person" doesn't mean you agree with cyc about anything. 19:03:35 exactly, if we want to deal with the WEB in Semantic WEB we need to think about some of these things. 19:03:59 I agree with you Dan, but again, documentation to date is mum on this - yet ALL my students did this without being told to. 19:04:26 i.e. they all referred to and/or extended existing ontologies without using includes. 19:29:51 mdean has joined #webont 19:30:12 mdean is now known as mdean_ 19:41:02 nmg has joined #webont 19:43:01 * DanC is getting hungry 19:44:45 nmg, have we met? 19:44:58 I don't think so, no. 19:45:17 dlm has joined #webont 19:45:18 \me has met some of the other rdf people (dan brickley, etc) 19:47:36 hmm... one n in Mcguiness-pbdsl2. Your name has 2, right? 19:47:56 * DanC wanders off for a bite to eat... 19:47:59 yes - ijust tried to fix that with going to file/local identifier and updating it 19:48:03 it did not seem to take. 19:48:22 * JHendler Dan - bring the milk and cookies for the group meeting! 19:53:32 libby has quit 19:59:31 Ian has joined #webont 20:00:23 kohlhase has joined #webont 20:00:59 =========== telecon starts =========== 20:01:07 Frankh has joined #webont 20:01:09 JosD has joined #webont 20:02:31 wow... 17 on the phone, per http://www.w3.org/1998/12/bridge/Zakim.html 20:02:33 jdale has joined #webont 20:02:41 hello 20:02:49 * DanC joins 20:03:12 hi jon - how's SF today? 20:03:23 12 Nov agenda: http://lists.w3.org/Archives/Public/www-webont-wg/2001Nov/0043.html 20:04:05 pretty wet - very bad rain this morning 20:04:25 and actually a little lightening and thunder - odd for sf 20:04:28 not a good day to be driving - i saw at least 8 accidents on the 280 20:04:45 seems to have calmed down a bit now 20:05:14 las has joined #webont 20:05:39 JimH: pls use the IRC channel for meeting business (including getting the chair's attention, clarifying). 20:05:43 dlm is now known as DeborahMcGuinness 20:05:54 are we supposed to be phoning in, too? 20:06:01 yes 20:06:04 ah 20:06:10 so what's the IRC session for? 20:06:26 just for scribing and for clarification 20:06:36 * jdale dials in 20:06:41 timfinin has joined #webont 20:07:26 stefanjdecker has joined #webont 20:07:28 ora has joined #webont 20:08:26 hi tim 20:09:31 $ grep ^Y nov12telcon|wc 20:09:31 24 162 1186 20:09:48 ===== Roll Call 20:09:59 24 present.

"The products of the WebONT group should not presuppose any particular approach to 20:50:26 either ontology design or ontology use.

"maximum compatibility with XML and RDF language conventions. " so we'll be working with RDF Core on things like model theory, datatypes, etc. 20:54:30 JimH: unlike groups like the "standard upper ontology" group, we don't intend to standardize any particular base of knowledge, but rather a language for expressing ontologies. 20:55:06 ... e.g. if someone proposed "this is how time should be represented..." that would be out of scope. 20:56:25 ... out of scope: query rules, query language, Universal Web Logics 20:56:49 * DanC wonders who's asking 20:56:59 NedS: how do you see DAML-S fitting in? 20:57:25 JimH: I think we want to support that sort of work, but DAML-S itself is out of scope. 20:57:53 NedS: how about as an environment for testing etc? 20:58:36 JimH: not sure about "environment"... but yes, we'll be interested in their requirements w.r.t. expressing ontology. 20:59:00 OraL: I participate in the DAML-S work, in case we need a connection. 21:00:52 JimH: we'll also be keeping track of other W3C working groups as well as other groups like FIPA... 21:01:05 JonD: I've been appointed representative from FIPA to here. 21:01:20 ora has left #webont 21:01:56 JimH: note also the European Union has issued a [... scribe missed it.] 21:02:31 ... semantic web initiative. 21:02:59 [... more charter review...] 21:03:03 "To be successful, we expect the Working Group to have approximately 10 to 20 active principal 21:03:03 members for its 12-month duration.

(a) how about a crash-course? (b) let's pore over DAML+OIL in detail and see what issues are there. 21:07:37 JimH: ideally, we'd have a ftf presentation; unfortunately, we can't wait 'till then... 21:07:48 Ian: how about the walkthru? 21:08:22 FrankvH: we could present the walkthru by phone... [thinking out loud] 21:08:59 IanH: I'm still not clear how we'd define an implementation 21:09:32 JeremyC: implementation is my main focus in participation here... at HP, we have an RDF implementation, and we're interesting in moving "up the stack"... 21:10:09 ... for example, it would have Java classes that make it straightforward to work with this language... perhaps including a DL [ description-logic ] reasoner. 21:10:13 mdean has joined #webont 21:10:19 mdean is now known as mdean_ 21:10:21 JonD: if we're [@@] 21:13:12 DanC: [use cases->testing; RDF Core WG experience: parser testing, entailment tests] 21:13:38 DebM: I'm maintaining a "modelling issues" page... http://www.ksl.stanford.edu/people/dlm/daml/modelingIssues.html 21:13:40 if there is a question on the call, can we please get an answer before going on to something else? 21:13:59 * DanC didn't realize there was a question outstanding 21:14:23 what counts as an implementation. 21:14:51 did you get cut off? 21:16:05 what counts as an implementation? supporting those test cases... 21:16:43 PeterPS: I'm still interested to know what counts as an implementation... 21:16:54 DanC: note that this group will largely decide that (with some review) 21:17:08 PeterPS: so this group will do the "this implementaiton is good enough" work? 21:17:17 DanC: yes, mostly. (see also: new QA WG) 21:18:02 JimH: it's not necessarily an integrated product... could be a mix of tools and toolkits that counts as an implementation 21:18:44 DanC: if we decide that's OK, that'll probably work. But other groups (e.g. CSS) have decided that they want one piece (or 2 pieces) of widely-deployed software that passes all their tests. 21:19:12 JeremyC: an important motivation for the implementation requirement is to test that the spec is clear. 21:19:17 [... missed other stuff...] 21:21:36 DanC/JimH: let's do start collecting use cases: real-world scenarios where "if it doesn't do this, I'm not happy" 21:22:17 ====== next meeting 21:22:24 week of 22 Nov is not likely. 21:22:45 stay tuned for news of next telcon sometime in the week of 26 Nov 21:23:00 ====== ADJOURN. 21:23:22 * JosD bye 21:23:39 Ian has quit 21:24:15 danc, should we get a chump for here? 21:24:19 dajobe has joined #webont 21:24:20 JosD has quit 21:25:16 a chump: that might be nice... 21:25:19 I'd be in favour of a chump - the one on #rdfig is pretty useful. 21:25:20 ... or mabye I'd rather have just one. 21:25:52 Frankh has quit 21:25:56 i.e. maybe I don't want to check two different chumps to see "what's up" 21:26:26 +1 (if I get a vote) 21:26:27 I am also interested in use-cases - it would be optimal for those to be connected to the modeling issues i mentioned 21:26:30 DavidTrastour has quit 21:27:20 bye all 21:27:24 jdale has left #webont 21:30:55 bye 21:30:59 nmg has left #webont 21:33:23 I like the chump idea as well - Libby, can we make it your action item to bug dajobe and DanC until they do it. 21:33:34 heh 21:33:37 ok 21:33:41 hmm 21:33:56 or I could do it probably 21:34:00 maybe bijan's semantichump? 21:34:12 maybe - is it out yet? 21:34:14 or stick with one we know works? 21:34:33 yeah 21:34:41 might make the logger rather messy 21:34:45 kohlhase has quit 21:35:03 I've been thinking about logger and chump relationship 21:35:08 but maybe take this to #rdfig 21:35:17 see, why you don't want two channel? :) 21:37:59 moving over to #rdfig - g'night all (afternoon to the Californians) 21:38:51 see ya 21:38:52 DanC: so did you decide on a meeting time, so I can turn on/off logger; or at least know when to check it is working? 21:39:13 (or JHendler) 21:39:54 dajobe: not yet, we need to query the WG - DanC will know... 21:40:00 np 21:41:11 dajobe has left #webont 21:44:17 bye 21:44:20 libby has left #webont 22:01:32 DeborahMcGuinness has quit 22:02:15 pfps has quit 22:03:05 JHendler has quit 22:10:08 pfps has joined #webont 22:10:11 JHendler has joined #webont 22:10:14 JHendler has quit 22:36:46 mdean_ has quit 23:19:03 [GlobalNotice] Hi all. I'm not sure how well-announced the backslide to the old server code was, but we'll be restarting the new code within the next few minutes. We had a rather nasty server rehash corruption problem. We'll keep you posted.
