| 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 |
