12:43:42<dmiles_afk>i was woken up a few minutes ago with the voice of timbl over bbc world service ;P
12:44:59<darobin>heh
12:46:51<timbl>sorry i'll try to be quieter in themornings
12:47:06<ldodds>ACTION grins
13:22:14<dmiles_afk>hrrm i wonder if there isa good CycL to RDF translitertion.. i have a program that Cyclifiies english to CycL
13:22:57<dmiles_afk>not an just an ontology dump .. but full cycl
14:57:25<twanj>in case anyone is interested, we updated metalinks (which lists mirrors, checksums, and other info for downloading) to danbri's RDFization - http://download.packages.ro/metalink/testing/debian/rdf/
15:16:03<timbl>twanj, just looked with tabulator, see http://www.metalinker.org/publisher etc is 404
15:21:38<twanj>timbl, what do I need to put there? I'm just stumbling along here :)
15:53:16<bblfish_>can one find things in SPARQL that don't have relations linking to it ?
15:53:33<LeeF>example?
15:54:40<bblfish>something like:
15:54:41<bblfish>PREFIX foaf: <http://xmlns.com/foaf/0.1/>
15:54:41<bblfish>PREFIX sioc: <http://rdfs.org/sioc/ns#>
15:54:42<bblfish>CONSTRUCT { ?s ?r ?o . }
15:54:42<bblfish>WHERE {
15:54:42<bblfish> NOT { ?xxx ?rrr ?s }
15:54:43<bblfish> ?s sioc:email ?m ;
15:54:45<bblfish> ?r ?o .
15:54:47<bblfish> FILTER ( ! REGEX(str(?m), "mailto:.*@.*") )
15:54:49<bblfish>}
15:55:15<bblfish>I want to find sioc accounts that have broken info, and that are not linked to by anything
15:55:40<LeeF>You're looking for resources that are not asserted as the objects of any triples?
15:56:04<bblfish>yes
15:56:28<bblfish>then I can prune them
15:56:50<LeeF>SELECT ?r
15:56:51<LeeF>WHERE
15:56:51<LeeF>{
15:56:51<LeeF> ?r a my:resourceType .
15:56:52<LeeF> OPTIONAL { ?s ?p ?r } .
15:56:54<LeeF> FILTER (!bound(?s)) .
15:56:56<LeeF>}
15:57:00<LeeF>should be correct, I believe.
15:57:05<bblfish>ah: clever :-)
15:57:13<LeeF>!bound is SPARQL-ese for "not"
15:57:31<bblfish>LeeF: it would be really nice to have CONSTRUCT *
15:57:39<bblfish>It gets tedious rewriting the graph twice
15:58:30<LeeF>Please send the comment to public-rdf-dawg-comments@w3.org if you wish -- but before you do, you might want to peruse this thread which I just stumbled across while looking through previous SPARQL QL last call threads: http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2005Nov/0045.html
15:59:11<LeeF>(I haven't read the thread, just saw it in the list.)
16:00:19<dajobe>yeah, construct* was deleted, wasn't it something to do with bnodes?
16:01:08<dajobe>the scope of bnodes in sparql is a lot clearer now
16:06:38<bblfish>ACTION conf call
16:56:40<timbl>ACTION reconnects
16:58:08<timbl>twanj, as it is a URI witout a hash in it fo a predicate you need to do a 303 redirect from /publisher to say /ontology and then ontolgy should return with 200 an RDF file desribing each predicate you have.
16:58:57<timbl>Stuff like /publisher is a property, label "publisher", stuff like that
16:59:32<timbl>See best practices http://www.w3.org/TR/swbp-vocab-pub/
17:00:08<timbl>will tell you how to set up a redirect with pache
17:01:15<timbl>apache
18:32:19<twanj>timbl, the clueless appreciate the guidance, thanks
