01:15:54<leefaus>hello
13:44:45<hendler>join #tami
14:55:21<sandro>is there a way to hack up At-Most-One QCR in OWL 1.0 ?
15:11:44<timbl>ericp, /devel/WWW/2006/gen/ont generic resources ontology iirc
15:11:54<timbl>scuse me
15:12:10<timbl>like http://www.w3.org/2006/gen/ont
15:23:21<bengee>sandro, I don't think so. there is only the workaround to invent a sub-property for each value type
15:27:02<sandro>So I want to say every BostonResident has zero or one belovedBaseballTeam, but not restrict the global cardinality of belovedBaseballTeam. I can't do that in OWL, right?
15:28:28<bengee>beloverBaseballTeam looks like a fitting sub-prop already
15:28:36<bengee>deloved even
15:28:42<bengee>sigh
15:29:06<bblfish_>clark&parsia have a dead link on http://pellet.owldl.com/docs/ in the link "Debugging OWL ontologies"
15:29:22<sandro>Does that help me, bengee?
15:30:50<bengee>in this case you can say something like :BostonResident owl:subClassOf [a owl:Restriction; owl:onProperty :belovedBaseballTeam; maxCardinality 1]
15:31:48<sandro>that looks like you're saying the Restriction has a maxCardinality.
15:32:03<bengee>i.e. the "qualified" part of QCR is already implicit in the range of belovedBaseballTeam
15:33:28<bengee>yeah, the owl:Restriction is the class of resources which have at most one belovedBaseballTeam relation
15:34:05<bengee>and every BostonResidents is a member of that class
15:34:05<sandro>I don't think you can say that in OWL.
15:34:39<bengee>that should be correct, but I admit that I haven't looked at the spec in ages..
15:34:57<sandro>oh, wait. maybe you're right.
15:36:25<bengee>a (q)cr it should be doable that way if you have this sort of InterpretationProperty
15:36:31<sandro>Yay. I was confusing Qualified Cardinality Constraints with Local Cardinality Constraints. All is good.
15:37:22<bengee>owl 1.0 can't handle something like "belovedTeam", and you want to say value-type=BaseballTeam and cardinality <=1
16:22:05<TedThibodeauJr>sandro - I'm not sure that the count of belovedBaseballTeam is always going to be zero or one... a fair number of people have "childhood" and "chosen hometown" teams -- as well as the issue of cities with multiple teams. just to throw an extra wrinkle into things.
16:25:44<sandro> sorry, TedThibodeauJr, it was just an example. the real situation I'm working on is less-intuitive.
16:28:01<TedThibodeauJr>:-) cool. so hard to tell fakeExample from realEffort in these things!
16:32:21<sandro>And you know I'm such a baseball fan. :-)
16:33:29<libby>people, anyone know the latest atom-in-rdf thingy?
16:34:05<bengee>rss1.0 ;)
16:34:09<danbri_>.g atom-owl
16:34:12<phenny>danbri_: http://atomowl.org/
16:34:13<danbri_>maybe?
16:35:07<libby>it's for non-rdf-heads so I don;t think 10 is gonna wash. I thought maybe 1.1...
16:35:28<libby>"Firefox can't find the server at bblfish.net." :(
16:35:56<bblfish>libby: yes, I am just moving the server
16:36:02<bblfish>try bblfish.org for the momnet
16:38:33<bblfish>mhh let me see
16:38:41<danbri_>libby you mean "rss 1.0" when you say "10"?
16:39:11<libby>ah thanks bblfish
16:39:12<danbri_>does atomowl use the official atom ns at w3.org for the rdf ?
16:39:21<danbri_>any buy-in or support from the atom incrowd?
16:39:21<libby>yeah mmistyped
16:39:43<bblfish>no. that would require it to be finished and approved by everyone.
16:40:15<danbri_>ACTION nods
16:40:24<bblfish>while the server is down you can get the source here: https://sommer.dev.java.net/atom/
16:40:24<danbri_>have you looked at an rdfa expression of it?
16:40:28<libby>can look later bblfish
16:41:04<libby>(context: we've put some rdfa in the joost links pages but people want it for search results and channel detail as well)
16:41:17<bblfish>danbri_: no, I am a bit tired of this as I spent a lot of time on it. I do need external enthusiasm to get back to it
16:41:28<libby>poor bblfish
16:41:43<bblfish>;-)
16:41:50<bblfish>:-/
16:42:28<libby>ah thanks for the link
16:42:32<bblfish>reverse engineering semantics is a tiring job
16:42:48<libby>yeah :-/
16:42:50<libby>no fun
16:42:59<libby>hard to do in a principled way too
16:43:42<libby>examples don;t work bblfish...
16:43:55<libby> https://sommer.dev.java.net/atom/2006-06-06/examples/example-1.n3
16:44:10<libby>ACTION can wait tho
16:50:49<bblfish>libby: they should work now. At least they do with curl https://sommer.dev.java.net/atom/2006-06-06/examples/example-1.atom.n3
16:53:30<libby>thanks! :D
16:54:39<bblfish>you can also check out the whole subversion repository of course
16:55:43<bblfish>and if you want access to it, your welcome :-)
17:00:18<libby>ACTION will hang on for now, but thanks :-)
17:28:34<sandro>ACTION is stunned by the ontology of nesting behavior of loggerhead sea turtles.... http://www.mesquiteproject.org/ontology/ It's cool, but, wow. Applications.......
17:29:07<sandro>eg: http://www.mesquiteproject.org/ontology/Loggerhead/abbreviated/Diagonally_Opposite_Throw.html
17:48:42<danbri_>"diagonially opposite throw" sounds like a wrestling ontology
17:48:56<sandro>:-)
18:01:45<bblfish>ok so content negotiation now works again here: http://bblfish.org/work/atom-owl/2006-06-06/
18:12:04<bblfish>ACTION that domain name is temporary. bblfish.net should be back soon
18:55:14<sandro>Are there any big social networking sites other than livejournal which have live foaf support?
18:59:38<danbri_>tribe.net ... dunno how many users...
18:59:46<danbri_>ecademy...
19:03:38<ericP># vs. / rages on in HCLS
19:04:23<ericP>the groupthink on # is that that the interpreation of the fragment is dependent on mime type?
19:04:46<ericP>what fraction of the common terms out there are # vs. /?
19:05:10<ericP>i have the impression that dc and foaf make up most of the deployed data, but that most of the other schemas use #
19:06:20<ericP>and what should i do if i offer and HTML version of a namespace document backing <http://example.org/#foo>, should it have a way to resolve #foo?
19:06:24<fgiasson>danbri_: about 300 to 350k (couples of months ago)
19:06:36<fgiasson>(tribe.net)
19:23:18<DanC>sandro, advogato has foaf support. it's moderately big
19:36:32<ericP>DanC, could you give http://esw.w3.org/topic/HCLSIG_BioRDF_Subgroup/Tasks/URI_Best_Practices/Recommendations/DraftTalk#line-258 a quick look to see if i've correctly characterized _Differentiating Between Web Resources and What They Describe_ ?
19:40:24<sandro>Thanks, DanC. I guess that might work. (it's for an example of Joe Random folks with FOAF files, but maybe Advogato is close enough to mainstream for this.)
19:41:13<sandro>Do you have an advodato-based URI for yourself?
19:41:33<sandro>(come to think of it, I don't think lj actually gives users URIs. :-/)
19:51:40<sandro>yeah, they use bnodes for people.
19:54:51<logger>ACTION is logging
