The message "OWL is RDF" has not been heard. 10:21:58 Good morning Steve - see the Guardian today? http://www.guardian.co.uk/media/2009/apr/01/guardian-twitter-media-technology 10:25:57 OWL folks routinely talk about OWL not being RDF 10:26:08 i'm not surprised that folks are mislead 10:46:08 what does GRAPH { FILTER (?i > 0) } do? 10:49:13 Evaluate to the empty result set. Sec 12.5 / GRAPH / part 2 : http://www.w3.org/TR/rdf-sparql-query/#defn_evalGraph 10:52:03 Was that the question? 10:52:48 pretty much 10:53:30 i was thinking about whether these two are different: 10:54:17 { GRAPH { /* matches at least one row */ } FILTER (1 = 1) } 10:54:35 { GRAPH { /* matches at least one row */ } GRAPH { FILTER (1 = 1) } } 11:03:33 Yes. And feel free to use FILTER(true) - this isn't SQL-92 11:16:26 AndyS: no, looking 11:16:41 haha, good. liked the El Reg Apple patent one better 11:17:24 The Guardian one is prominently on page 5 of the paper version. Go for it! 11:24:15 AndyS, not a bad one indeed 11:24:43 there is also an opera news: http://labs.opera.com/news/2009/04/01/ and a google chrome one: http://www.google.com/intl/en/landing/chrome/cadie/ 11:26:35 I wonder whether we will have something like the flying pinguins http://www.youtube.com/watch?v=nrxmpihCjqw 11:27:57 el reg are running something on a apple patent: http://www.theregister.co.uk/2009/04/01/apple_secrecy_patent/ 11:44:41 AndyS has joined #sparql 11:44:52 AndyS has joined #sparql 11:45:06 AndyS has joined #sparql 11:45:24 AndyS has joined #sparql 11:45:36 AndyS has joined #sparql 11:47:16 SimonS has joined #sparql 12:10:58 AndyS has joined #sparql 12:23:50 given an empty default graph, FROM NAMED { GRAPH { /* matches at least one row */ } FILTER (true) } gives no results? 13:22:27 AndyS has joined #sparql 13:23:00 AndyS has joined #sparql 13:24:11 AndyS has joined #sparql 13:37:19 sandro has joined #sparql 13:41:56 EricP : re: "given an empty default graph" - not no results. As many as GRAPH... 13:42:45 I misread the {} in an earlier query : { GRAPH { /* matches at least one row */ } FILTER (1 = 1) } mathes as many times as /**/ 13:57:52 thanks, AndyS 15:38:06 SteveH has joined #sparql 16:50:43 ivan has joined #sparql 16:59:20 ivan has left #sparql 18:10:13 SteveH has joined #sparql 20:20:01 SteveH has joined #sparql
