14:06:00 <DanC> high irony: I just got a surface-mail ad from the C/C++ users journal. "Q: Quick! What's wrong with this code? class Ff { ... }" is the teaser on the envelope
14:06:08 <DanC> my answer: It's written in C++!
14:06:25 <Morbus> hey, i got that too.
14:06:31 <Morbus> and you know what, that's *exactly* what I said.
14:06:37 * Morbus ^5's DanC.
14:06:50 * DanC returns ^5
14:08:21 <deltab> hehe
14:09:49 <jang> I have to grudgingly agree
14:09:56 <jang> a language should not be a logic problem
14:10:27 <jang> C++ has too many different things that look alike.
14:11:17 <DanC> the irony is so intense... presumably a C/C++ journal would tout the *benefits* of a language.
14:11:40 <DanC> but they're using the *problems* of the language to get the attention of prospective subscribers.
14:12:04 <deltab> I read something that claims C++ is popular because it gives programmers something to fiddle with while they're thinking about hard problems
14:12:18 <jang> C++ has a refreshingly start attitude to inheritance ambiguity: it's an error
14:12:26 <jang> s/start/stark
14:12:36 <jang> however, there's a rgeat deal of linguistic ambiguity there
14:13:29 <jang> it comes from all over the shop: the attempt to keep C's neat "declaration looks like use" syntax
14:13:57 <jang> but when the number of ways to use things expand, the number of potential things that a statement/declaration might be goes up
14:14:31 <jang> it's pleasant to use C++ to write "scripting" tasks: _using_ class libraries that are well-designed (eg, the boost stuff) is rather good
14:14:42 <jang> writing the bloody things in the first place is a nightmare

15:29:27 <shaggy> heya
15:29:41 <shaggy> I've got a quick build question...
15:29:55 <shaggy> I've noticed that there are 2 librdf's built...
15:30:06 <shaggy> one with a T on the end? what's up with that?
15:30:57 <shaggy> that one segfaults on an embedded linux platform I'm working on, the other one doesnt. Just wondering.
15:31:43 <libby_> hm, that looks like something of dajobe's
15:32:03 <libby_> libby_ is now known as libby
15:32:18 <dajobe> eh?
15:32:48 <dajobe> shaggy: you'll need to give a little more context for me
15:33:06 <dajobe> .google librdft
15:33:07 <datum> librdft: sorry, no results were found.
15:33:14 <dajobe> ^- scary
15:35:06 <shaggy> no, check it out..
15:35:25 <shaggy> -rwxrwxr-x 1 buildmas buildmas 372153 Apr 23 15:14 librdf.so.0.0.0
15:35:25 <shaggy> -rwxrwxr-x 1 buildmas buildmas 372089 Apr 23 15:14 librdf.so.0.0.0T
15:35:44 <shaggy> that's the contents (partial) of librdf/.libs
15:35:55 <dajobe> ah libtool
15:36:02 <dajobe> firstly, don't ever look in there ;)
15:36:03 <shaggy> I was just wondering why the T one gets installed
15:36:09 <shaggy> <grin>
15:36:19 <dajobe> what system are you running on? uname -a would help
15:36:27 <shaggy> sure...
15:36:41 <dajobe> I've not seen that and I've built redland on all sorts of strange systems such as OSX
15:36:55 <shaggy> Linux buildmaster 2.4.7-10 #1 Thu Sep 6 17:27:27 EDT 2001 i686 unknown
15:37:07 <dajobe> oh, regular linux x86
15:37:19 <shaggy> this is our build machine. eventually the binaries go onto an embedded SBC
15:37:27 <dajobe> ah, cross compiled
15:37:34 <dajobe> I suspect T=target binary then
15:38:11 <shaggy> ahhh...
15:38:35 * dajobe guessing
15:38:40 <shaggy> ok, I was just wondering. one of my co-workers said you were very helpful and available via IRC.
15:38:48 <shaggy> keep up the good work. cheers!
15:38:56 <dajobe> thanks, a user, yay

15:58:02 <libby> oops
15:58:24 <libby> heyho
15:58:51 <DanC> I'd rather not reduce the old business to one agendum.
15:59:02 <DanC> I like to review actions in the context of the agendum in which they're assigned.
15:59:13 <DanC> so let's put x-properties and namespaces on the agenda
15:59:17 <DanC> etc.
15:59:24 <libby> ok
15:59:44 <DanC> scheduling the next meeting is non-trivial, to me.
15:59:54 <DanC> wanna do that toward the beginning or toward the end?
16:00:15 <libby> BLURB: RDF calendar agenda item (D) x-properties and namespaces
16:00:15 <dc_rdfig> D: RDF calendar agenda item (D) x-properties and namespaces from libby
16:00:24 <libby> we normally do it at the end....
16:00:30 <DanC> ok
16:00:52 <libby> yeah, actually I don;t think I can make the next one as originally scheduled
16:01:04 <DanC> D:|x-properties and namespaces (agenda item D)
16:01:04 <dc_rdfig> Titled item D.
16:01:19 * DanC plays with agenda notations

16:03:24 <dc_rdfig> G: useful vocbularies for events (e.g. location, topic...) (agenda item G) from libby
16:03:54 <DanC> hmm... G seems a little open-ended. we really want to talk about how to put our ical vocab into RSS, no?
16:04:09 <libby> BLURB: authoritativeness and completeness of data for scheduling purposes (agenda item H)
16:04:10 <dc_rdfig> H: authoritativeness and completeness of data for scheduling purposes (agenda item H) from libby
16:04:29 <libby> yeah, G is open ended, need not just be RSS vocab though, could be dublin core for example
16:04:50 <DanC> well, it could be; but it's most likely gonna be RSS.
16:04:53 <DanC> no?
16:05:00 <DanC> i.e. let's focus. let's make real test cases.
16:05:12 <DanC> if the test case ends up being dublin core in stead, very well.
16:05:28 <libby> BLURB: round-tripping RDF ical tests, toIcal.py (agenda item I)

16:07:14 <danbri> Re RSS 'vs' DC, RSS statements (title/description/uri) _imply_ DC statements, via subPropertyOf in the RSS 1.0 schema.
16:07:29 * danbri nominates libby
16:07:33 <DanC> I'm also willing to fly chair-less
16:07:55 <libby> ok, I'll chair, and pass the floor to Danc for the first few items on the agenda if that's ok

16:08:32 <libby> thanks for coming along mattb, eikeon
16:08:39 <DanC> great, libby.
16:09:07 * DanC is tempted to put SUMO update on the agenda... seems over-full already though.
16:09:08 <libby> ok, danc, want to talk about x-properties and namespaces (agenda item D)?
16:09:35 <DanC> right... well, we decided that my --xnames command-line option sucks ;-)
16:10:07 <DanC> we sketched a design (using hashes and such), and libby took an action to give it a go in code/tests. Any progress?
16:10:26 <libby> no, I'm sorry, that one got away
16:10:42 <libby> I think I got distracted into building the schema using cwm

16:10:59 <dc_rdfig> Added comment D1.
16:11:35 <DanC> D:ACTION libby: to build/test what we decided on 26Feb, continued
16:11:35 <dc_rdfig> Added comment D2.
16:11:51 <DanC> I'll say that the --xnames hack continues to suck.
16:12:22 <DanC> actively. i.e. it continues to cost me. So I'm very pleased that you're willing to pick up work on it.
16:12:44 <DanC> I might find a round tuit meanwhile, but I dunno.
16:12:49 * libby hopes it's not too much work .... ;)
16:12:50 <DanC> Maybe I can get ryan lee to do it.
16:13:05 <DanC> anything else on x-properties?
16:13:36 <libby> not from me - shall we move to cal/geo usecase 1: opening hours of a thing that has a place (E)?
16:13:59 <DanC> E:continued from [9Apr|http://rdfig.xmlhack.com/2003/04/09/2003-04-09.html#1049903200.904995]
16:14:00 <dc_rdfig> Added comment E1.
16:14:10 <DanC> any progress on "ACTIOn libby write a converter from chefmoz opening housr format to rdf calendar format (or icalendar format maybe?)"?
16:14:22 <libby> no, still nothing... :(
16:14:32 <DanC> would you prefer to continue or withdraw?
16:14:37 <libby> I stil think it should be relatively simple, still not done it
16:14:43 <libby> continue is fine
16:14:47 <danbri> woudl you like help?
16:14:52 <libby> sure :)
16:14:55 <DanC> yeah, any volunteers?
16:15:06 <danbri> I can do everything except the function that takes the chefmoz property and emits the RDF...
16:15:19 <danbri> ie download scrub and emit the data, for some subset...
16:15:22 <DanC> elaborate, danbri?
16:15:39 <DanC> "function that takes the chefmoz property..." ... example, please?
16:15:49 <danbri> Libby writse a perl/ruby/java/python function that takes the funny opening hour strings from chefmoz, and returns the appropriate rdf/xml
16:16:10 <libby> all of them!? ;)
16:16:15 <danbri> i'll wrap that in something that actually emits a bunch of RDF/XML restaurant reviews with this bit added in.
16:16:20 <DanC> I've been writing N3 rules using string:scrape to do string munging of that sort, danbri. interested?
16:16:25 <libby> that'd be great danbri
16:16:52 <danbri> I think that'd be a steep learning curve for me DanC... (though I'm learning a bunch from studying Cwm's APIs)
16:17:17 <danbri> we want one owner for the action (libby hopefully) but do name me in the action writeup so i remember it.
16:17:19 <DanC> E:ACTION libby: write a converter from chefmoz opening housr format to rdf calendar format (or icalendar format maybe?). continues, with danbri helping
16:17:19 <dc_rdfig> Added comment E2.
16:17:44 <DanC> learning: right. you guys seem to have a handle on it.
16:17:54 <mattb> re zool
16:18:16 <DanC> what news on "ACTION danbri_fr to have a draft of the 'concentric circles' within100m schema/vocab for next week"?
16:18:29 <libby> hey zool
16:18:33 <DanC> I think i saw progress on that...
16:18:42 <zool> re mattb libby
16:18:49 * DanC considers indicating the current agenda item in the /topic
16:19:18 <libby> re danbri's action, tehre's http://esw.w3.org/topic/GeoOnion
16:19:26 <libby> but there's also some more discussion somewhere
16:19:38 <eikeon> Are there pointers to the chefmoz bits... how to get the string that needs converting.
16:20:00 <DanC> E:re 'concentric circles', see [esw:GeoOnion|http://esw.w3.org/topic/GeoOnion]
16:20:01 <dc_rdfig> Added comment E3.
16:20:19 * danbri saves http://esw.w3.org/topic/GeoOnion
16:20:25 <DanC> danbri, do you claim victory on 'concentric circles'? I guess it's done to my satisfaction, but I wasn't there 9Apr
16:20:42 <danbri> I submit that I'm stuck. I just added some more explanatory prose, but the scale isn't really usable.
16:21:04 <danbri> I feel blocked and mathematically clumsy. If someone could help with calculating a better sscale, I'd take further actions on this.
16:21:12 <DanC> how about writing some examples?
16:21:13 <danbri> But for now I think I should declare victory.
16:21:22 <danbri> I just started to ;)
16:21:40 <DanC> { :hotelWhereImStaying :within100metersOf :sandwichShop } # walking distance
16:21:51 <danbri> OK, I'll paste that in :)
16:22:05 <DanC> strike the {}s
16:22:12 <DanC> put . before #
16:22:28 <DanC> (perhaps link to ["ShorthandRDF"])
16:22:43 * DanC checks time; 20min into 90min slot
16:23:04 <libby> was that all the actions for review danc?
16:23:11 * libby thinks so
16:23:35 * danbri updates http://esw.w3.org/topic/GeoOnion
16:23:40 <zool> eikeon, re chefmoz, grubstreet latest work here http://un.earth.li/~kake/cgi-bin/wiki.cgi?action=rss&feed=chef_dan&id=Calthorpe_Arms%2C_WC1X_8JR if not seen
16:23:56 <DanC> yes, there are no more actions, but discussion of "opening hours of a thing that has a place " is in order.
16:24:21 * danbri ooohs at http://un.earth.li/~kake/cgi-bin/wiki.cgi?action=rss&feed=chef_dan&id=Calthorpe_Arms%2C_WC1X_8JR/
16:24:29 <danbri> ...though not sure if changed since i last looked
16:24:37 <libby> danc, where's that from?
16:24:41 <eikeon> zool: thank you.
16:24:42 <danbri> I feel foaf:topic is working out rather nicely, btw
16:24:47 <libby> ok got it
16:25:16 <DanC> yes, foaf:topic++ (except for SlashVsHash ;-)
16:25:24 <libby> danc, anything in particular re "but discussion of "opening hours of a thing that has a place " is in order."
16:25:29 <libby> ?
16:25:48 <danbri> Oh also should mention that DanC reworked the GeoInfo page rather nicely, which re 'things with a place' might interest various folks here -- http://esw.w3.org/topic/GeoInfo
16:26:29 <DanC> somebody this E thing on our agenda 9Apr. actions were assigned, which causes the item to be carried forward until they're complete or withdrawn. We've reviewed the actions, but we can continue to discuss the item until folks want to move on.
16:26:32 <eikeon> SlashVsHash looks good to me ;)
16:26:36 <DanC> somebody put...
16:26:53 <danbri> An idea for soemthing re things, place, opening hours... identify something that is in both ChefMoz and Grubstreet, and use that to show augmentation (via merging or whatever) of data from the two sources.
16:27:19 <DanC> logger_1, pointer?
16:27:19 <DanC> See http://ilrt.org/discovery/chatlogs/rdfig/2003-04-23#T16-27-19
16:27:33 <libby> are you volunteering danbri? sounds like an excellent idea...
16:27:46 <DanC> E:[irc log|http://ilrt.org/discovery/chatlogs/rdfig/2003-04-23#T16-27-19] includes more pointers and discussion
16:27:47 <dc_rdfig> Added comment E4.
16:27:49 <danbri> ah, there is geo stuff in http://un.earth.li/~kake/cgi-bin/wiki.cgi?action=rss&feed=chef_dan&id=Calthorpe_Arms%2C_WC1X_8JR now, i forget it wasn't there before.
16:28:05 <danbri> anyone know how many lat/longs in there? is it for every pub/restaurant?
16:28:17 * DanC gets wierd HTTP foo at earth.li
16:28:36 <DanC> no, got wierd HTTP foo somewhere else...
16:28:50 <danbri> I volunteer but won't take an action beyond the 'help you' one above, will just try to use examples that merge with Grubstreet coverage.
16:28:57 <mattb> i may have scuttered it, can check...
16:29:06 <libby> ok, cool danbri
16:29:34 <libby> ok, I propose that we move to the next agenda item, as we have many
16:29:35 <DanC> E:|cal/geo usecase: opening hours of a thing that has a place (item E)
16:29:35 <dc_rdfig> Titled item E.
16:29:44 * DanC doesn't think the usecase number (1) is useful
16:29:54 <DanC> right, moving on
16:30:18 <libby> so, agenda item F, EventDiscovery
16:30:30 <danbri> wikinames might work well for use cases, as they're meeting independent. Using Chump ID, 'E:' etc is confusing over several meetings...
16:30:54 <danbri> logger_1, pointer?
16:30:54 <danbri> See http://ilrt.org/discovery/chatlogs/rdfig/2003-04-23#T16-30-54
16:31:14 <DanC> yes, wiki topic work well for agenda that last for more than one meeting
16:31:26 <DanC> topic
16:31:27 <DanC> topics
16:31:32 * DanC note to self: learn to type
16:31:45 <libby> re EventDiscovery, who here has a harvester?
16:31:57 * eikeon started eikster.com in the spirit of "and to encourage it to be put out there!" and started an events section.
16:32:33 * eikeon does
16:32:33 <DanC> well, I don't have a harvester, but I did some work to connect my foaf "home KB" to my travel schedule. I think that was a sort of wishlist (not quite action) as of a few meetings ago.
16:32:54 <mattb> i have http://www.hackdiary.com/archives/000030.html
16:33:01 <DanC> I'd like to know if my travel schedule and itineries are getting scuttered
16:33:05 <eikeon> DanC: Are these some of your events showing up: http://eikster.com/2003/events/
16:33:08 <libby> that the travel tools page danc?
16:33:25 * libby has a scutter too
16:33:25 <danbri> I have a harvester, now bundled in RubyRdf that can scutter rdfs:seeAlso links. I've not yet found any calendar 'table of contents' page to point it at, though.
16:33:31 <mattb> DanC: i got about 1700 triples off one of your rdf URLs earlier today
16:33:38 <mattb> somethignsomething/smart/something.rdf
16:33:43 * mattb would have to check logs
16:33:50 <mattb> event-related i think
16:33:57 <DanC> F:[danc's foaf home KB|http://www.w3.org/People/Connolly/home-smart] or [home-smart.rdf|http://www.w3.org/People/Connolly/home-smart.rdf]
16:33:57 <dc_rdfig> Added comment F1.
16:33:58 * danbri updates http://esw.w3.org/topic/EventDiscovery to point to this chat, and to Matt's tool and RubyRdf...
16:34:13 <libby> that's cool eikeon :)
16:34:19 <DanC> I enhanced my XSLT homepage scraper to put seeAlso links to my travel schedule and itineraries
16:34:29 <danbri> oh cool
16:34:38 <libby> eikeon, how can information in your database be accessed?
16:34:49 * DanC enourages folks to put cool stuff in the weblog
16:34:56 <danbri> oh nearly forgot
16:35:30 <libby> I'm interested in mattb's ideas about subscribing to certain kinds on information in a RDF db
16:35:35 * DanC looks to see if http://eikster.com/2003/events/ has any of my stuff...
16:35:40 <eikeon> All the information in the events page is available in rdf/xml... the rdf_flyer icon at the top of the page.
16:35:47 <mattb> yeah, i don't see everyone running their own harvesters
16:35:48 <danbri> F:I started notes in [http://esw.w3.org/topic/AnnounceOMatic|ESW:AnnounceOMatic] towards harvesting event data from W3C mailing lists, specifically conference announcments...
16:35:48 <dc_rdfig> Added comment F2.
16:36:00 <libby> mattb, have you got a minute or two talk about your ideas?
16:36:03 <DanC> bingo! "AMERICAN AIRLINES #1549 from KANSAS CITY INTL to DALLAS FT WORTH"
16:36:08 <mattb> libby: i'll give it a go
16:36:19 <libby> thanks mattb
16:36:19 <danbri> re AnnounceOMatic, Caroline Meek at ILRT is going to have a rummage back through archives for a few months, look for common patterns...
16:36:23 <mattb> i expect lots of domain-specific applications to turn up out there that would need to crawl the whole rdfweb to find the bits they need
16:36:44 * danbri nods
16:36:49 <eikeon> Looks like AA #1549 etc events are coming from: http://www.w3.org/2003/05dc-bud/bud25Mar.rdf
16:36:52 <mattb> also, no point wasting all that bandwidth
16:37:03 <mattb> and harvesters should be well-behaved, respecting robots.txt, using ETags, etc
16:37:15 <libby> yup
16:37:19 <mattb> see RSS-hoovering bandwidth problems over the last few months as rss goes through a renaissance
16:37:22 * danbri whistles, looks at the floor, walls etc guiltily
16:37:28 <libby> mine isnlt well behaved
16:37:32 <mattb> also, a harvester should run continuosly
16:37:37 <mattb> not re-spidering once a day/week/whatever
16:37:49 <mattb> my current code remembers lots about what it saw during its plan
16:37:56 <mattb> and can now say whether a URL is updated since last run or not
16:37:59 <DanC> PROPOSED(F1): that all attendees of this meeting who build robots shall respect robots.txt and use ETags
16:38:08 <libby> does it record what it knows in RDF mattb?
16:38:14 <mattb> libby: yup
16:38:14 <libby> e.g. in a scutterplan?
16:38:20 <libby> neat, got an example?
16:38:28 <mattb> <url> <scutter:etag> "'foobarblah'" .
16:38:39 <mattb> <url> <scutter:lastModified> "2003-04-03 12:00" .
16:38:41 <mattb> etc
16:38:45 <libby> danc, I'll take an action to sort mine out re robotos.txt
16:38:50 <danbri> Seconded. I'll take an action to fix RubyRdf scutter in that regard.
16:38:50 <eikeon> My harvester is doing much the same... guilty on not paying attention to robots... but to ETag and pay attention to 404s etc.
16:39:02 <DanC> PROPOSED(F2): that all attendees of this meeting who build robots should respect robots.txt and use ETags or at least explain why not
16:39:10 <libby> cool eikeon
16:39:11 <mattb> i can dump out the scutterplan rdf bits this evening, put them up as example
16:39:20 <libby> thanks, that'd be great
16:39:29 <mattb> so, knowing what's new at least on a per-URL level, it could send out notifications about what it's found
16:39:32 * DanC hopes folks will say: I second F2.
16:39:36 * mattb seconds F2
16:39:40 * danbri does too
16:39:52 <libby> yep, sounds good to me
16:39:55 <danbri> respec!
16:39:56 * eikeon is interested in a schema where such information could be shared between harvesters.
16:39:57 <mattb> it could also know what apps are looking for what kinds of triples, and notify them only when they come along
16:40:02 * DanC asks that the chair put the question by saying "any objections to F2?"
16:40:07 <libby> ok
16:40:10 <mattb> yeah, scutterplan-sharing sounds sensible
16:40:12 <libby> any objections to F2?
16:40:20 <mattb> more than just the current form of a file full of rdfs:seeAlsos
16:40:20 <libby> that's be good mattb
16:40:35 <mattb> there should be stuff as in my examples above at least
16:40:50 <eikeon> So that if harvester A just cheched and document B has not changed harverster C can get that info from harvest A type of thing.
16:40:51 * DanC asks that the chair announce that the motion carries, at which point I'll tell dc_rdfig
16:41:05 <mattb> i have a prototype notification system that POSTs to registered URLs with an rdf document saying "here's some new stuff, headline info about it, and where you can get it if you want it"
16:41:12 * libby wasn;t sure how long to wait danc
16:41:22 <DanC> how long you wait is up to you, libby
16:41:24 <mattb> in other words, clients do the selection of what to download, notifications are broadcast to everyone
16:41:34 <libby> ok, F2 carries since there are no objections
16:41:46 <DanC> F:RESOLVED that all attendees of this meeting who build robots should respect robots.txt and use ETags or at least explain why not
16:41:47 <dc_rdfig> Added comment F3.
16:41:48 * mattb braindumping into channel, sorry to keep chatting via important process issues :)
16:41:56 * mattb at work...
16:42:01 <danbri> scutterplan sharing is very useful... also I'd like to provoke some collaboration on smarter heuristics for rdf crawlers. At the moment, the traverse-everything methodology re rdfs:seeAlso works, cos the Semantic Web is tinyish. But not for long...
16:42:03 <mattb> s/via/during/
16:42:06 <danbri> keep going matt :)
16:42:06 <DanC> braindumping is in order. we love IRC. ;-)
16:42:17 <libby> yeah, mattb, interesting stuff
16:42:22 <danbri> yes, agree re sharing amongst harvesters
16:42:22 <mattb> yeah, i'd like scutterplans to be graphs too
16:42:24 <mattb> not just lists
16:42:34 <mattb> x -> y -> (a -> b, c -> d) -> etc
16:42:36 <libby> like typed links?
16:42:43 <mattb> with annotations on why they were followed
16:42:52 <danbri> I think (mentioned this in #foaf a few times) the old Harvest project (C+Perl) worked out a lot of this for us, including Squid (which I think was theres) for cache sharing...
16:42:53 <mattb> particularly if there were hints in the origin document along with the seeAlso
16:42:53 <DanC> what are the ()s in x -> y -> (a -> b, c -> d) -> etc?
16:43:00 <danbri> Encouraging typed links in seeAlsos:
16:43:01 <DanC> oh... like n3 ;
16:43:02 <mattb> (boss)
16:43:11 <danbri> (hide!)
16:43:38 <danbri> <rdf:Description foaf:name="Dan Brickley"><rdfs:seeAlso rdf:resource="http:etc"/></rdf:Description> is useful.
16:43:46 <zool> mmm
16:43:56 <danbri> <foaf:Person foaf:name="Dan Brickley"><rdfs:seeAlso rdf:resource="http:etc"/></foaf:Person> is more useful.
16:44:09 <DanC> <x> s:seeAlso [= <y>; s:seeAlso [= <a>; s:seeAlso <b>], [= <c>; s:seeAlso <d>]].
16:44:24 <danbri> <foaf:Person foaf:name="Dan Brickley"><rdfs:seeAlso><foaf:BiblioDoc rdf:about="http://"/></rdfs:seeAlso></foaf:Person> is EVEN more useful.
16:44:37 <danbri> ie. you can mention types at either end of the seeAlso arc.
16:44:44 <libby> I like taht a lot
16:44:52 <libby> e.g. here's a calendar associated with me
16:44:54 <danbri> To bring it back to this meeting's goals, we could have foaf:CalendarDoc...
16:45:05 <libby> or maybe Vcalendar
16:45:07 <danbri> I've not really looked into a design for that...
16:45:12 <eikeon> And preferably at both ends of the arc, perhaps ;)
16:45:19 <DanC> why foaf:CalendarDoc when we already have ical:Vcalendar? oh yeah... not all Vcalendars are docs
16:45:22 <danbri> Yes, I think i asked previously if Vcalendar class was appropriate, but were some issues.
16:45:31 <danbri> yep...
16:45:45 <danbri> this would be a subclass of writeme:RDFXMLDocument...
16:45:58 <libby> vcalendar might be ok if there's at least one vcalendar at the other end
16:46:00 <libby> maybe
16:46:02 <danbri> the subclass of RDFXMLDocuments that describe a Vcalendar, perhaps
16:46:06 <libby> seems a shame to double up
16:46:27 <DanC> ok, so I connected my foaf home to my travel itinerary and eikon's harvester noticed. Now the geek in me is very pleased, but... ummm... how can impress my grandma with that? i.e. what actual value are we after?
16:46:28 <danbri> yup... I feel we're only slightly blocked from something quite useful... :(
16:46:43 <libby> I was particularly interested in the idea of subscribing to certain sorts of data from a database, e.g. via a query
16:46:59 <danbri> Didn't Jim Ley do some more pathcross in SVG stuff? SVG's nice for impressing the non-geek...
16:47:04 <danbri> sorry for the vague ref...
16:47:12 <DanC> can this harvester stuff help me play PathCross?
16:47:27 <eikeon> Something useful might be to get out meeting events into RDF/XML and have our bots be able to remind us and/or set the topic etc.
16:47:42 <libby> it mkight be able to if you could pull out potentail crosses via a query danc
16:47:45 <danbri> It can get you the data that allows you to ask questions that'll find the subset of data that'll help w/ pathcross...
16:47:46 * libby likes queries
16:47:55 <DanC> has anybody else published, formally (i.e. in RDF/XML) the fact that they plan to attend WWW2003?
16:48:16 <danbri> eg. people do dumb/blunt stuff in SQL aggregates, then invoke Cwm directly on selected URIs identified... (possible deployment combo)
16:48:27 <danbri> not me. Tell me what to type to assert that...
16:48:52 <eikeon> Is there a VEvent for WWW2003 somewhere?
16:48:55 * DanC wonders if eikon's scutter pulled WWW2003 out of my travel schedule; I don't think I declared it to be an ical:Vevent
16:48:59 <mattb> (unboss)
16:49:04 * mattb reads back
16:49:26 <libby> danc, I have in icalendar, but not RDF :(
16:49:46 <mattb> i have a feeling the "here's my query, tell me when you have new matches" problem is at least vaguely hard
16:49:50 <DanC> where, libby? how about you run ical2rdf on it right quick?
16:49:56 <mattb> certainly if full generality of rdql or similar is offered
16:50:10 <mattb> it's gotta be something you can bulk-match, not run N queries for N people on every new URL/changed URL
16:50:15 <libby> eikeon, I want to do that and have written a bot to do that, but I don;t know the best way to get the right data for it fromsomewhere
16:50:36 <libby> danc, yeah, ok
16:50:39 <DanC> hard in what way, mattb? implementations of graph-match-strength query engines are pretty easy to come by, around here. And euler can even do better than that.
16:50:48 <eikeon> libby: I leverage my existing harvester ;)
16:50:54 <libby> :)
16:50:59 <libby> yeah
16:51:02 <mattb> DanC: partly gut feeling
16:51:12 <eikeon> ... and could extend eikco to do it, if people like.
16:51:18 <zool> libby yeah what is the right data... are you taking bot/REST approach a la mudlondon, picbot
16:51:21 <DanC> now if libby runs ical2rdf on her ical file, that'll assert that WWW2003 exists. Will it connect libby with that event?
16:51:29 <mattb> but i don't think it'd be possible to accept a new subgraph into a store and say that some of its triples matched a query without checking again the existing complete graph
16:51:30 <libby> eikeon, I (and I'm sure others can ask a query of my db and get ntriples back
16:51:33 <libby> yep zool
16:51:38 <eikeon> Else maybe pull data from: http://eikster.com/2003/events/?content_type=application/rdf%2Bxml
16:51:44 <mattb> in the case where the existing graph has some of the triples req'd and the subgrpah completes the graph required for results
16:51:50 <libby> ok, handy, thanks eikeon :))
16:51:50 <DanC> hmm... how to say "I'll be there!"
16:51:53 * mattb defers to those wth more query-optimising knowledge
16:51:58 <libby> attendee?
16:52:12 <DanC> you mean ical:attendee?
16:52:17 <libby> do you have an code for the subscribe thing mattb?
16:52:19 <danbri> mattb, yup its a belief-update-problem, when you learn new stuff, not clear which other conclusions need revising... so you end up requerying everything
16:52:21 <libby> yeah...
16:52:28 <danbri> maybe ok, can do in batch or round-robin...
16:52:41 <mattb> libby: yes, for the basic announce-and-clients-do-what-they-like-with-it
16:52:45 <mattb> i have java server, perl client
16:52:49 <mattb> the client bit is pretty trivial
16:53:00 <DanC> I've been using { ?E cyc:socialParticipants ?WHO }. now why haven't I been using { ?E ical:attendee ?WHO}? hmm...
16:53:09 <mattb> i see it as a separate rest/rdf messaging system that the scutter could use as a toolkit
16:53:22 <mattb> it's an implementation of some stuff posted to the rest-discuss list, with the xml rdf-ized
16:54:36 <DanC> some part of me hesitates to say that WWW2003 is an ical event. ical events have exactly one organizer who has exactly one mailbox, and I dunno if WWW2003 works that way. or something.
16:54:36 * danbri wonders where we go from here... we have people, we have events, we have harvesters, but but but...
16:55:00 <danbri> I'm willing to run with cyc:socialParticipants or whatever folk recommend, just looking to do what someone tells me ;)
16:55:23 * eikeon proposes action that would result is more events finding there way to/from rdf/xml
16:55:28 <mattb> i'd like to build some little demo apps that use a harvester and pubsub mechanism
16:55:29 <eikeon> ... whatever that may be.
16:55:40 <zool> ical:attendee sounds good, though odd ns
16:55:51 <mattb> i would also like to split a harvester into a url-discover-checker-and-downloader-and-notifier and a storage system
16:55:52 <zool> forkage, event:participant
16:56:06 <mattb> iow i don't think harvesters should necessarily aggregate the entire graph of what they find
16:56:24 <zool> what side will the smushing go on mattb
16:56:42 <mattb> smushing would happen in a smushing store subscribed to the crawler i think
16:56:58 <mattb> it could do arguably-dodgy things like bnode-labeling to help simple clients
16:56:59 <libby> ok, there's my calendar data danc - not sure if it came out right: http://ilrt.org/people/libby/calendar/exportrred20030414.rdf
16:57:00 * eikeon is currently smushing at query time.
16:57:33 <mattb> i would like it if the crawler's only state was its scutterplan and annotations
16:57:34 <DanC> F:[Upcoming Events discovered on the Semantic Web|http://eikster.com/2003/events/], a service by eikon, found my flights.
16:57:36 <dc_rdfig> Added comment F4.
16:57:43 <zool> sounds lush; so i need smushing on the aggregator end; i still dont have an algo i'm happy with
16:57:54 <danbri> this is very much the harvest gatherer/broker and cacheing design (I'm not complaining -- it's an obvious pattern)...
16:58:03 * mattb steals all the best ideas
16:58:14 <eikeon> libby: Added... and more events show up :) http://eikster.com/2003/events/
16:58:20 * DanC perks up at "obvious pattern" ... esw wiki topic, pls?
16:58:28 <mattb> reminds me of discussion of federated, specialised stores and query-systems discussed with zool and yoz last summer
16:58:31 <danbri> I'd be willing to repackage a .tar.gz of re-serialized scuttered RDF (though I worry about privacy laws etc...)
16:58:51 <DanC> libby, now can you connect that calendar from your foaf home via rdfs:seeAlso?
16:58:54 * danbri nods to DanC, but I can't think of a good wiki topic
16:59:01 <mattb> i have a demo of bnode-labelled (for smushing) reserialized RDF notification, but it keeps the re-generated model in memory
16:59:10 <mattb> so it's conceptually a transitory message with a time-to-live
16:59:18 <libby> so, I'm thinking we shoudl try to come up with some action-type things to end discussion of this tpoic for now, as we have many things to get through and 30 mins to go...
16:59:19 <mattb> i wouldn't like the idea of permanently republishing other people's RDF with extra stuff on
16:59:24 <libby> danc, okey dokey
16:59:27 <danbri> I wish I'd gotten to go to http://www.w3.org/Search/9605-Indexing-Workshop/ -- looked v interesting
16:59:37 <DanC> F:a wiki topic around "the harvest gatherer/broker and cacheing design" seems to be brewing... near pubsub
16:59:38 <dc_rdfig> Added comment F5.
16:59:39 <danbri> ...maybe we should have another?
16:59:54 <danbri> (big job though)
17:00:21 <DanC> eikon, http://eikster.com/2003/events/ sparks my curiousity... I'd like a "view source" sorta link... what query is it running? how often?
17:00:51 <DanC> can you add people and places to the query somehow?
17:01:11 <DanC> events do seem to be ordered by date; that's cool.
17:01:45 <eikeon> DanC: query is done on page request. And source is at: http://eikster.com/2003/hypercode
17:02:13 <DanC> F:[source of eikster.com upcoming events|http://eikster.com/2003/hypercode]
17:02:13 <dc_rdfig> Added comment F6.
17:02:20 <libby> eikeon, cool!
17:03:34 * danbri visits http://eikster.com/2003/events/ sees "staff meeting at ILRT"
17:03:50 <eikeon> Um... code is a bit hard to follow with the inner/outer hackage going on to share code between html and rdf/xml view of events page.
17:03:57 <danbri> i'm reminded of skical, i think they've been further than most in national event gathering... maybe some lessons re implicit contexts
17:04:09 <danbri> eg. "Mother's Day" <- in which country?
17:04:15 <danbri> (US vs UK varies)
17:05:03 <DanC> re "in which country", the cool think about 2003/event/s is it's got the "oh yeah?" button next to each event. so you can follow the link to http://eikster.com/2003/US32Holidays.rdf
17:05:35 * DanC awards eikon 200 points for implementing an "oh yeah?" button
17:05:37 <libby> ok, I've linked my rdf calendar witha typed seealso from http://swordfish.rdfweb.org/people/libby/rdfweb/webwho.xrdf
17:06:09 <libby> hehe, re ILRT meeting
17:06:15 <danbri> eikeon, this is very cool! sorry if i leapt straight in with questions/nitpics. nice work :)
17:06:37 * libby looks at clock, agenda
17:07:14 * DanC doesn't mind if this item consumes the rest of the meeting
17:07:17 <danbri> does anyone have code that goes from rdfical back to ical? I'd like to use that now I have harvester happily working and a Mac w/ iCal to view .ics files on...
17:07:17 <eikeon> danbri: The icon to the right of the event label links to the source... in the case of mothers day the source url provides a nice clue ;) http://eikster.com/2003/US32Holidays.rdf
17:07:19 * danbri neither
17:07:24 * danbri just noticed :)
17:07:29 <DanC> back to ical: yes...
17:07:45 <DanC> ... http://www.w3.org/2000/10/swap/pim/toIcal.py
17:08:43 <DanC> PROPOSED(F.a): that folks should be encouraged to link their calendars from their foaf home thingies via rdfs:seeAlso (@@e.g. danc's, libby's)
17:09:02 * libby seconds F.a
17:09:13 <DanC> PROPOSED(F.att):that folks should use ical:attendee to relate themselves to events that they plan to attend.
17:09:23 * DanC isn't sure about F.att
17:09:45 <DanC> PROPOSED(F.att.cyc):that folks should use cyc:socialParticipants to relate themselves to events that they plan to attend. (@@e.g. danc's travel schedule)
17:09:46 <libby> it's tricky. attendee points to an email address?
17:09:48 <danbri> funny, I was studying http://www.w3.org/2000/10/swap/pim/toIcal.py recently, but just for the API, i didn't notice what it was _for_ :)
17:10:06 * danbri adds it to EventDiscovery (by hand, wonders about installing wikibot here)
17:10:15 <libby> danc, how do you refer to yourself in that file?
17:10:41 <danbri> re F.a, 2nd'd.
17:10:52 <DanC> in an itinerary: <r:Description r:about="bud25Mar.n3#thisTrip">
17:10:52 <DanC> <k:firstSubEvents r:resource="bud25Mar.n3#_gflt1549_3"/>
17:10:52 <DanC> <k:lastSubEvents r:resource="bud25Mar.n3#_gflt1319_14"/>
17:10:52 <DanC> <k:passengers r:resource="http://www.w3.org/People/Connolly/home-smart#me"/>
17:11:28 <danbri> re F.att*, do those properties carry the meaning of anticipated attendence?
17:11:41 <danbri> ie. we can't use them to determine who actually attended
17:11:42 <DanC> phpht. in http://www.w3.org/People/Connolly/travel-sched , I don't connect myself to events. :-{
17:12:08 * libby checks rfc2445
17:12:19 <DanC> any offers to shout loudly in the foaf community re F.a?
17:12:40 <zool> is there a definitive-enough reference file for attaching events to myself?
17:12:46 <libby> I wonder how easy it is to connect yourself to an event using calendar tools
17:12:57 <mattb> how do you pick the object of such a triple?
17:13:03 <mattb> canonical URL for www2003? or literals?
17:13:09 * mattb apologises if this has been overdiscussed
17:13:13 <libby> we would have to be able to recommend using mbox or mbox_sha1sum
17:13:17 <libby> re foafers
17:13:27 * eikeon will add a page to view an individual event showing attendees... when we know what property(ies) we want to use... and there is some data to test with.
17:13:49 <libby> could use foaf:homepage to connect event and cononical url
17:13:54 <DanC> I expect GUI calendar tools to keep the association with the user implicit. I'd use a command-line option on ical2rdf.pl to say "make it explicit that I, <http:.../#me>, plan to attend all these events"
17:14:06 * DanC has an example somewhere...
17:15:11 <eikeon> Or I, <http:.../> ;)
17:15:45 <DanC> ah... in my WWW2003 makefile: 05dc-bud/Makefile: $(PERL) $(GROKI) --aboutMe $(ABOUTWHO) --localName $(WHO) < $< >$@.nt
17:15:55 <libby> rfc 2445: 4.8.4.1 Attendee....Value Type: CAL-ADDRESS; "This property MUST
17:15:55 <libby> NOT be specified in an iCalendar object when publishing the calendar
17:15:55 <libby> information"
17:16:25 <DanC> yeah... grubby protocol constraints like that are why I hesitate to say that WWW2003 is an ical:Vevent
17:16:39 <libby> [[
17:16:40 <libby> Formal Definition: The value type is as defined by the following
17:16:40 <libby> notation:
17:16:45 <libby> cal-address = uri
17:16:46 <libby> ]]
17:17:01 * DanC challenges eikeon to a duel for the honor of HashURIs ;-)
17:17:03 <danbri> <DanC> any offers to shout loudly in the foaf community re F.a?
17:17:14 <danbri> sure though not sure quite what to shout yet
17:17:28 <libby> well www2003 could still be a vevent, but use the cyc property not attenddee
17:18:32 <DanC> my WWW2003 makefile: http://www.w3.org/2003/05dc-bud/Makefile
17:19:08 <DanC> meetingbot, pending proposals?
17:19:26 <DanC> PROPOSED(F.att.cyc):that folks should use cyc:socialParticipants to relate themselves to events that they plan to attend. (@@e.g. danc's travel schedule)
17:19:34 * libby enthused to work on calendar bot via eikeon's harvester
17:19:35 <DanC> PROPOSED(F.att):that folks should use ical:attendee to relate themselves to events that they plan to attend.
17:19:45 <DanC> PROPOSED(F.a): that folks should be encouraged to link their calendars from their foaf home thingies via rdfs:seeAlso (@@e.g. danc's, libby's)
17:20:08 <DanC> yeah, but meetingbot, how many 2nds for each of those?
17:20:09 <danbri> what's the range of: cyc:socialParticipants ?
17:20:13 <libby> F.a I seconded
17:20:18 <DanC> cyc:Agent, I think, danbri
17:20:20 <libby> F.att is tricky
17:20:22 <eikeon> DanC: :) -- I recently jump from the Hash side of the fence to Slash for my own usage. As I kept bumping into cases where I wanted a URIRef with a hash to make it to the server... but the hashes do not make it ;(
17:20:40 <DanC> so it doesn't look like we'll close on F.att. shall I follow up in email?
17:20:49 <libby> that'd be great danc
17:21:23 <DanC> F:ACTION DanC: follow up in email about how folks should relate themselves to events they plan to attend. ical:attendee? cyc:socialParticipants?
17:21:25 <dc_rdfig> Added comment F7.
17:21:31 * libby wonders about harvesters and repeating events
17:21:35 * eikeon seconds F.a
17:21:37 <DanC> (meetingbot notes that F.att.* are withdrawn)
17:21:45 <libby> any objections to F.a?
17:22:36 * danbri 3rds F.a (for RDF docs only, not .ics...)
17:22:36 <libby> an expander from repeating events to non-repeating version has been suggested before, but non-trivial I think
17:23:30 <DanC> as the meeting closes, note that you all have about 10 hours to decorate the (scratchpad/weblog part of the) meeting record with stuff that you want to be able to find without poring over the IRC log.
17:23:47 <DanC> i.e.
17:23:48 <DanC> .time
17:23:49 <datum> Wed, 23 Apr 2003 17:23:48 GMT
17:24:00 <DanC> the chump bot rolls over and loses its marbles at 24:00Z
17:24:09 <libby> PROPOSED(F.a): that folks should be encouraged to link their RDF calendars from their foaf home thingies via rdfs:seeAlso (@@e.g. danc's, libby's)
17:24:25 <eikeon> What happens after 10 hours... does it get frozen? /me curious.
17:24:29 <libby> any objections to ammended F.a?
17:24:30 <DanC> F:RESOLVED: that folks should be encouraged to link their RDF calendars from their foaf home thingies via rdfs:seeAlso (@@e.g. danc's, libby's)
17:24:31 <dc_rdfig> Added comment F8.
17:24:37 * DanC oops
17:24:51 <libby> I think ok danc, just checkoing the RDF bit
17:24:53 <danbri> seems agreed-enough to me
17:25:05 <DanC> best if somebody followed up on F.a with an article or something, though I suppose it's not critical
17:25:22 <mattb> eikeon: at midnight GMT the frontpage goes into the archive
17:25:22 <libby> an article?
17:25:27 <mattb> and the chump starts again at A:
17:25:34 * DanC likes the fact that if anybody didn't think it was resolved, they could scribble it out.
17:25:43 <eikeon> mattb: ty
17:25:50 <libby> ok, we have 5 minutes, shall we discuss time and date of next meet?
17:26:16 <DanC> yes (and record it under A)
17:26:17 * danbri nods, suggests fortnightly working ok for now...
17:26:31 * DanC tries to compute now() + 1 fortnight
17:26:33 <libby> it should be on 7th May, but I will be at XMLEurope, notsure about internet access yet
17:26:40 * mattb at xmleurope also
17:26:45 <mattb> prolly no net access
17:26:47 <mattb> if it's like last year
17:26:55 <mattb> speakers' notes say no net connection for speakers
17:27:00 <libby> !
17:27:16 <mattb> etcon it is not
17:27:35 <DanC> <#event_-1515880520> k:temporallyIntersects <#theDay2003-05-07>;
17:27:35 <DanC> rdf:value """RDF Calendar """; is foaf:topic of <http://calendar.sidekick.dngr.com/event?id=486&event-date=2003-05-07>.
17:27:54 <DanC> ^ i.e. it's already in my calendar
17:28:15 <DanC> and there aren't any conflicts.
17:28:21 <libby> we did say every 2 weeks till www2003
17:28:35 <libby> so, we can do that
17:28:42 <DanC> I guess I'm willing to convene a meeting on 7 May... regrets from libby?
17:28:53 <libby> great, thanks danc
17:29:02 <libby> yep, regrets from me
17:29:10 <DanC> just a sec...
17:29:40 <DanC> PROPOSED(A.next7): to meet next on 7May 1600Z, per every-other-week agreement. danc to call the meeting. regrets from libby.
17:29:44 * DanC would like a 2nd
17:29:56 * eikeon wonders if next meeting is finding its way into rdf/xml ?
17:30:17 <DanC> it's in RDF/N3 above ;-)
17:30:26 <danbri> 2nd'd, but hmm i'm considering xml europe attendance...
17:30:27 <libby> it's in with the time incorrect in my file as a repeating event
17:30:42 <libby> eikeon, but I normally create an rdf file for each meet, will do.
17:30:59 <DanC> can anybody else confirm for 7May?
17:31:07 <eikeon> libby: Nice :)
17:31:20 <mattb> danbri: i think 7th may is when we are all doing our semweb talks
17:31:25 <mattb> me, celia, zool, uche, etc
17:31:34 <mattb> so you gotta come see us ;)
17:31:39 <DanC> PROPOSED(A.cxl7): to cancel 7May meeting.
17:32:32 * danbri nods re cancel
17:32:35 <DanC> I withdraw my offer to convene a meeting 7May
17:32:39 * libby seconds A.cxl7
17:32:51 <libby> ok, so next meeting...?
17:32:57 <DanC> so what's 7May+2 weeks? are we in Budapest by then?
17:32:58 * mattb heads for home
17:33:02 <mattb> interesting chat, cheers
17:33:03 <libby> yep
17:33:07 <libby> mattb, thanks
17:33:16 <libby> yep re budapest
17:33:22 <libby> we could do 14th, in between
17:33:36 <DanC> oops; we assigned actions before we figured out when we'd have a chance to review them.
17:33:47 * DanC checks 14May
17:34:08 <DanC> no conflicts.
17:34:36 <DanC> PROPOSED(A.next14): to meet next on 14May at 1600Z.
17:34:49 <danbri> 2nd'd.
17:34:53 * libby seconds A.next14
17:35:04 <libby> any objections?
17:35:14 <libby> can anyone else make it?
17:35:24 * danbri believes so
17:35:55 * DanC notes folks were excused at xx:30, the scheduled end time
17:36:08 <libby> true
17:36:12 <libby> we're 6 mins over
17:36:20 <libby> maybe next time do scheduling first....
17:36:21 <DanC> A:next meeting looks like 14May at 1600Z, though we didn't formally decide.
17:36:22 <dc_rdfig> Added comment A6.
17:36:30 <DanC> A:RESOLVED: to cancel 7May

17:36:50 <dc_rdfig> Added comment A8.
17:37:00 <libby> thanks all, sorry for overrunning
17:37:06 <DanC> not at all.
17:37:09 <libby> very intersting chat today
17:37:13 <DanC> quite!
17:37:19 <libby> :)
17:37:27 <q|eve> q|eve is now known as qmacro
17:38:26 * libby looks at http://www.xmleurope.com/2003/wednesday.asp
17:38:35 <libby> wishes there was an RDF view...
17:39:00 <libby> does anyone know if there are official RDf versions of the WWW2003 schedule?
17:40:05 <libby> I did these: http://swordfish.rdfweb.org/discovery/2003/04/www2003/ but looking at the now, there are no timezones or anything
17:45:37 <eikeon> libby: Think I am going to rework how the rdf/xml views of pages on my sites work... will impact aggregated events rdf/xml... but not much.
17:45:53 <libby> cool
17:46:31 <libby> so much to do, so little time.....
18:06:42 <sandro> What breaks if you think of QNames as URIs XMLNS as providing a local-override URI Scheme? Anything?
18:06:53 <sandro> What breaks if you think of QNames as URIs, and XMLNS as providing a local-override URI Scheme? Anything?
18:44:14 * libby wonders what to suggest for the (late) rdf query testcases agenda
18:45:11 * danbri fails to understand sandro's proposal
18:45:11 <danbri> like file://dc/title vs xmlns://dc/title? or dc:title with dc: being the uri scheme?
18:46:50 <sandro> slashes are out, but why not just view dc:title as being itself a kind of relative-URI (in this case relative to some ns declarations instead of a base). ? It's just such a pain that
18:47:17 <sandro> "x:y" could be a qname OR a URI and the semantics are ALMOST the same, and maybe could be the same.
19:20:22 <libby> cheers for all the discussion mattb earlier, very interesting
19:20:30 <mattb> ta libby
19:20:37 <mattb> helps to talk it over
19:20:42 <mattb> ideas been in back of head for a while
19:21:07 <libby> :)
19:21:11 <mattb> haven't updated my foaf file for a while
19:21:20 <mattb> be interesting to do some event-attendance in there
19:21:31 <libby> yeah, definitely
19:21:50 <mattb> i was thinking about an index of pieces on my site using foaf:Document too
19:22:01 <libby> ooh
19:22:03 <mattb> should come up with a mapping from my movabletype categories into some useful ontology
19:22:18 <mattb> it'd just be a simple MT template probably, perhaps with a plugin
19:22:29 <libby> I've not looked at MT really
19:22:36 <DanC> what breaks you can't take dc:title and hand it to somebody else as a meaningful symbol. Yes, it works like a relative URI reference (timbl's n3 grammar has a uriref2 production that includes qnames) , but not like a URI.
19:22:38 <mattb> every article has an rdf index already
19:22:43 <mattb> eg http://www.hackdiary.com/archives/000030.rdf
19:23:23 <Morbus> mmmm. MT.
19:23:44 <libby> ooh, neato
19:24:22 <dajobe> that seems to use xlink
19:24:33 <mattb> yeah, random rdf i made a while back
19:24:43 <mattb> i wanted to ask earlier how best to encode the code of weblinking in rdf
19:24:47 <mattb> for my scutterplan really
19:24:52 <mattb> but we'd moved on in the agenda
19:24:54 <mattb> forgot about it
19:25:15 <mattb> dc:relation might work in the hackdiary case above i suppose
19:25:33 <mattb> "i found X on the web and it linked to Y" is the sort of statement i want to make in the scutterplan case
19:25:53 <dajobe> using the xlink terms might be confusing, people (software?) might interpret the XML links rather than leave them as rdf properties
19:25:59 <mattb> true
19:26:00 <dajobe> html:a ?
19:26:08 <mattb> good idea
19:26:11 <sandro> Thanks, DanC. That doesn't sound so bad -- we already use a lot of relative URIs, and understand how they are just syntactic sugar. We don't have an algorithm for turning a qname + NS-declarations into an absolute-URI, though. (and if we did, some people would probably get upsef....)
19:26:16 <dajobe> or maybe dc:relation ...
19:26:20 <mattb> it's actually scraped straight from <a href="foo"> in the original html
19:26:28 <dajobe> I expected it did
19:26:53 <dajobe> at least dc:relation has a schema around, no html rdfs I know
19:27:07 <mattb> i used dc:relation in something the other day
19:27:19 <mattb> oh, the upmystreet postcode<->latlong service
19:27:38 <dajobe> probably just as much use as rdfs:seeAlso hmm
19:27:54 <mattb> as in ihttp://www.picdiary.com/~mattb/rdf/e97qp.rdf
19:28:46 <mattb> the intention was to aggregate all the articles and say "((A linksto X) and (B linksto X)) implies (A relatedto B)"
19:34:25 <DanC> [[ We don't have an algorithm for turning a qname + NS-declarations into an absolute-URI, though. (and if we did, some people would probably get upsef....) ]]

19:51:31 * DanC was hoping to have that discussion in/around esw:GoodURIs
19:51:54 * DanC might excert some power vested in me as URI CG chair to get that to happen, to save Roy some grief
19:56:08 <danbri> my attempt at FAQ was midly flippant, but some form of Q'n'A about URIs might be a useful thing to explore

20:15:28 <mattb> yeah, i shall be there
20:15:42 <mattb> what's the format of developer day?
20:15:50 <mattb> what makes it different from the tracks?
20:15:54 <DanC> .google www2003 developer's day
20:15:56 <datum> www2003 developer's day: http://www.ai.mit.edu/people/dquan/resume.html
20:16:00 <DanC> ?
20:16:11 <mattb> the www2003 site doesn't make it entirely clear
20:16:30 <mattb> i asked eric miller by email but didn't get much response
20:16:38 <DanC> devday stuff is usually less baked...
20:16:46 <DanC> the track is for peer-reviewed stuff.
20:17:58 <DanC> have you been to a WWW conference? maybe the best answer is the #rdfig blog from dev day last year in hawaii...
20:18:06 <mattb> nope, my first time
20:18:17 <danbri> mattb, http://esw.w3.org/topic/RdfQueryTestingBudapestMeeting
20:18:38 <mattb> oh, cool
20:18:38 * danbri just sent mail again today trying to clarify its officially-blessed-ness, get it linked from www2003 site etc
20:19:08 <DanC> dev day 2002: http://www2002.org/devday.html
20:19:52 <danbri> "Join us for a unique opportunity to chat with TimBL, look back upon eight years of DevDays, see the latest Semantic Web demos, and kick around ideas for the Next Big Thing."
20:20:02 * mattb finds http://ilrt.org/discovery/chatlogs/rdfig/2002-05-11.html
20:20:03 <DanC> rdfig blog from devday 2002: http://rdfig.xmlhack.com/2002/05/11/2002-05-11.html
20:20:03 * danbri wonders what's lined up there... demo-wise
20:20:35 <danbri> ah, that was _last_ year. /me dohs
20:20:52 * danbri tries to remember demos at lunchtime, remembers only food, and ppl clamouring for an rdf query WG
20:22:39 <DanC> chuckle... 19:15:42 * dajobe-lap slaps AaronSw with a pointy bracket
20:23:11 <mattb> <DanC> ok, I wanna play with photo metadata tools
20:23:15 <mattb> same again a year later?
20:24:30 * dajobe remembers the speed typing, rubs his wrist
20:24:36 <mattb> good logs dajobe
20:25:22 <DanC> yes, life is a search for photo metadata tools.
20:26:16 <libby> danc, have you got a definition of http://www.w3.org/2000/10/swap/pim/contact#nearestAirport?
20:26:22 <DanC> i.e. what I want to say about my photos is not very much smaller than what I want to say about the world in general. likewise my calendar.
20:26:47 <mattb> yes, my stuff revolves around photos
20:26:53 <mattb> i don't have many words, except on irc
20:27:34 <DanC> nearestAirport... er... it's a property I used to ask WebOnt WG members where they sorta usually are in order to facilitate discussions about where we should hold our ftf meetings.
20:27:45 <DanC> does that suffice?
20:28:04 <DanC> in fact, it's *the* such property.
20:28:13 <danbri> its now an emergent standard for next generation PIM and stalker-support apps.
20:28:21 <libby> I was going to reuse it ... :)
20:28:34 <libby> it's been used in foaf files a fair bit I think
20:28:50 <DanC> the document currently available from http://www.w3.org/2000/10/swap/pim/contact doesn't authorize its use as a property, I don't believe.
20:29:13 <libby> yep, I just realized that
20:29:44 * libby inclined to think it doesn;t matter...
20:30:02 <DanC> it matters, but it matters a whole lot less than a lot of other things.
20:30:07 <qmacro> qmacro is now known as q|zzz
20:31:04 <libby> I wonder why www1.iata.org/codes redirects to the MS IE site?
20:31:04 <mortenf> heh, dajobe, re our rss version talk yesterday: http://use.perl.org/~gnat/journal/7774
20:31:29 * danbri finds 61 uses
20:35:59 <mattb> libby: you were asking about the model my scutter builds for its plan
20:36:05 <mattb> it's at http://www.hackdiary.com/rdf/scutterplan.rdf
20:36:27 <mattb> that's a dump straight from the database, no real polishing or deep thought gone into it
20:37:37 <libby> thanks mattb, that's very useful
20:38:32 <libby> mind if I add it to F in the chump?
20:38:42 <mattb> go ahead
20:39:39 <libby> F:[http://www.hackdiary.com/rdf/scutterplan.rdf|mattb's enhanced scutterplan] with lastmodified among other things
20:39:39 <dc_rdfig> Added comment F9.
20:39:40 <libby> ta
20:44:10 <mortenf> re the internal layered scutter "subscription" issue, i'd thought of specifying a (number of) classes/properties, and simply getting subject uris in return when something matches.
20:44:34 <mortenf> then the subscriber could query the store for actual info
20:44:46 <mortenf> thereby getting the complete graph.
20:46:33 <sandro>http://lists.w3.org/Archives/Public/uri/2003Apr/0062.html
20:46:34 <dc_rdfig> M: http://lists.w3.org/Archives/Public/uri/2003Apr/0062.html from sandro
20:46:47 <sandro> M:|[proposed] New Text for RFC 2396 intro, reframing what URIs are for
20:46:47 <dc_rdfig> Titled item M.
20:47:20 <sandro> (by me)
20:47:47 * sandro dives into the mud again, lured by a glimmer of hope.
20:52:09 <libby> mortenf, I'm not sure what you mean...got an example?
20:53:35 <mortenf> not really, was thinking mostly along the lines of rss, i.e. if a new (or updated) channel resource is added/updated in the triple store, one could request to be notified, receiving the uri of the channel resource.
20:54:28 <mortenf> probably too simple, since an rss channel is seldom updated, the rss:items sequence is...
20:55:14 <sandro> K: Yeah -- hash-vs-slash, how to be invertable, and what to do about people who don't write their XML with this in-mind......
20:55:14 <dc_rdfig> Added comment K5.
20:55:45 <mortenf> but, the major point was that a subscriber should get a uri of some sort, not a graph, in return.
20:58:18 <mattb> mortenf: sounds interesting
20:58:39 <mortenf> so far just an idea, not sure if it would work...
20:58:42 <mattb> doing simple predicate or subject matching would be possible without reference to the entire graph store
20:58:45 <mattb> that's the kind of thing i had in mind
20:59:06 <mattb> my current prototype gives the subscriber a URI
20:59:08 <mattb> seems the best way
20:59:30 <mortenf> yeah, and simple too!
20:59:40 <mattb> you can retrieve it when you like
21:01:42 <mattb> it's very similar to http://groups.yahoo.com/group/rest-messaging/message/3 but with an rdf model
21:04:59 <mortenf> hmm, yeah, but it just occurred to me that we might be talking about different issues - i was thinking about the issue of splitting up scutter/aggregator/etc..., not about the distributed notification system - but actually it seems like there's quite a lot of overlap...
21:11:48 <mattb> yeah, i see them as the same issue really
21:12:08 <mattb> scutter finds things, notifies the aggregator of *everything*, no special subs options available
21:12:20 <mattb> other things use the aggregator/store as a mediator with some query features
21:12:47 <mattb> you could run multiple distributed stores off the same scutter, for example
21:12:51 <mortenf> yep, and the "other things" could subscribe to the aggregator.
21:12:54 <mattb> exactly
21:13:05 <mattb> extra layers just give more capabilities
21:13:10 <mortenf> indeed
21:13:17 <mattb> you plug your app into the layer you like best, best impedance match
21:13:25 <mortenf> methinks there are some nice layered graphics waiting to be made...
21:13:27 <mattb> later layers could do inferencing, smushing
21:13:47 * mattb wishes he didn't have a flat to tidy, got code fingers
21:13:50 <mortenf> the problem is interfaces, and where to split the layers.
21:13:56 <mortenf> heh.
21:14:32 <mortenf> btw, did you invent your own vocab for the http header fields?
21:15:10 <Dorward> mortenf: OK, I'm working my way through this but by bit. <wot:assurance rdf:resource="morten.rdf.asc"/> - does that just point at the ASCII armoured signed version of the foaf file?
21:15:42 <mattb> yeah, didn't think too hard about vocab
21:16:00 <mattb> would be nice to have a general way of describing an http request
21:16:12 <mattb> didn't graham klyne do an rdf model of rfc822?
21:16:12 <mattb> http headers are similar
21:16:27 <mortenf> Dorward: yes.
21:16:36 <Dorward> mortenf: Thanks
21:17:13 <mortenf> i think i saw an incompete http vocab somewhere, i think eikeon was asking about it as well at some point.
21:17:22 <mortenf> s/incompete/incomplete/
21:17:57 <mortenf> Dorward: np, ask away...
21:18:43 <Dorward> mortenf: Is their a suitably lazy way to generate the current time in that ISO format you used for created?
21:19:05 <mortenf> hmm, language?
21:19:57 <Dorward> mortenf: Pretty much any, I'm on a Linux box. Perl by preference, but bash, ruby, java, python, etc are fine.
21:21:35 <DanC> wow... oasis has really gone nutso with TC automation... http://www.oasis-open.org/committees/calendar.php?month=5&year=2003&wg_abbrev=xri#full_calendar
21:21:37 <mortenf> erh, perl: strftime("%Y-%m-%dT%TZ",gmtime($stat->mtime))
21:23:21 <Dorward> mattb: Ta
21:24:11 <Dorward> mortenf: Complains about calling mtime on an underfined value, how do you init $stat?
21:25:08 <mortenf> $stat=stat($file)
21:26:09 <Dorward> mortenf: Ah, thanks. I'll fiddle with it from there.
21:26:36 <mortenf> cool, don't forget to show us when you're done :)
21:26:44 <Dorward> mortenf: :)
21:26:59 <dajobe> perl -e 'use POSIX; print strftime("%Y-%m-%dT%TZ",gmtime),"\n"'
21:27:11 <dajobe> for the current UTC time
21:27:19 <Dorward> dajobe: Handy. Thanks
21:30:20 <Dorward> Any documentation for the <lang: namespace (is namespace the right term?).
21:30:44 <mortenf> yep it is, and the should be some at the url itself.
21:30:51 <mortenf> s/the/there/
21:32:05 <Dorward> mortenf: You mean http://purl.org/net/inkel/rdf/schemas/lang/1.1#? ... Ah!
21:32:17 * Dorward learns how to interpret Schemas
21:32:25 <mortenf> pretty view (plug): http://xml.mfd-consult.dk/ws/2003/01/rdfs/?rdfs=http://purl.org/net/inkel/rdf/schemas/lang/1.1%23
21:33:26 <Dorward> Oh, must prettier :)
21:55:23 * Dorward finally notices that he slipped sideways in to another channel midconversation with mortenf
21:55:46 <mortenf> heh.
21:56:01 <Dorward> Are there any online validatation tools for FOAF (or XML in general)
21:56:23 <mortenf> .google rdf validator
21:56:24 <datum> rdf validator: http://www.w3.org/RDF/Validator/
21:56:39 <mortenf> ... is your best bet.
21:56:43 <Dorward> Ah ha
22:01:36 <Dorward> mortenf: It's giving me a warning about Element node must be qualified for <dateOfBirth> - what namespace does that come from?
22:01:55 <mortenf> that's foaf.
22:02:31 <mortenf> in my file i have xmlns="http://xmlns.com/foaf/0.1/" - the default namespace is foaf.
22:02:42 <Dorward> Ah, I see
22:05:21 * DanC toggles the 3rd of 4 items on my TODO list for the day... feels productive...
22:05:55 <mortenf> congrats, i'm 2/5...
22:06:00 * DanC looks at tomorrow, realizes he has owes WebOnt an action re I18N review that's getting stinky.
22:07:02 <Dorward> Righty, http://david.us-lot.org/foaf.rdf - first public release :)
22:08:59 <mortenf> looks nice. yet another plug/pretty view: http://xml.mfd-consult.dk/foaf/explorer/?foaf=http%3A%2F%2Fdavid.us-lot.org%2Ffoaf.rdf
22:10:47 <Dorward> That is a nice little application :)
22:13:49 * Dorward adds a plug for it at http://stone.thecoreworlds.net/contact/#foaf
22:14:46 <mortenf> nice, thanks.
22:15:01 <DanC>http://www.w3.org/TR/2003/WD-qaframe-spec-20030210/
22:15:02 <dc_rdfig> N: http://www.w3.org/TR/2003/WD-qaframe-spec-20030210/ from DanC
22:15:14 <DanC> N:|QA Framework: Specification Guidelines
22:15:14 <dc_rdfig> Titled item N.
22:15:22 <DanC> N:W3C Working Draft 10 February 2003
22:15:23 <dc_rdfig> Added comment N1.
22:15:29 <DanC> N:in last call, I think
22:15:30 <dc_rdfig> Added comment N2.
22:15:36 <DanC> N:wow... status section is over a screenful/page
22:15:37 <dc_rdfig> Added comment N3.
22:17:08 <DanC> N:odd... SOTD includes notice of open issues. I thought last call meant "all our issues are closed"
22:17:09 <dc_rdfig> Added comment N4.
22:17:10 <danbri> re foaf/rdf and 'validation', note that the site at http://www.semanticplanet.com/sources/58/polls/1661/ rather unfortunately does it wrong. It suggests that RDF data is bad where information is missed out which could be inferred from the RDF vocabulary used.
22:17:28 <danbri> eg "Statement object has wrong type
22:17:28 <danbri> In the statement <http://diveintomark.org/public/foaf.rdf#f8dy> <http://xmlns.com/foaf/0.1/interest> <http://python.org/> ., the object must be of type <http://xmlns.com/foaf/0.1/Document>" instead of
22:17:42 <danbri> ... 'the object can be inferred to be of type ....'
22:18:15 <mortenf> yeah, i think ian knows this.
22:18:21 <mortenf> (now)
22:19:15 <danbri> yes, i think so too. I wrote and lost (crash) a nicer message I wrote explaining the issues... i feel bad that our specs didn't make these distinctions clear enough...
22:20:27 <mortenf> well, it can still be of help sometimes, that approac.
22:20:35 <danbri> hmm, would anyone here be interested in a ScheduledTopicChat on FOAF?
22:20:40 <danbri> I realise we've never done that...
22:20:55 * danbri asking at wrong time of day...
22:21:03 <mortenf> yeah, perhaps to clear up the naming issues, for one?
22:21:36 <mortenf> and one agenda item for "brain storming"...
22:21:39 <danbri> Ah, I pinged some i18n folks at w3c about that earlier... had no easy answers, i'll try to summarise in a mail...
22:21:52 <danbri> brainstorming and stabilising
22:22:08 <mortenf> great, and yes.
22:22:11 <danbri> brainstorming vs stabilising, perhaps
22:22:17 <danbri> ok gotta go! g'nite all...
22:22:23 <mortenf> yeah, nn.
