This query still works, but it's a bit funky as it seems to produce rather repetitive output. I vaguely remember Lee Feigenbaum having a clever (if somewhat underhanded) fix for this at our tutorial in WWW2007, but I cannot find record of it anywhere. LeeF? The problem is that there are too many of the "same" results being produced by SPARQL: Here's the query: http://www.w3.org/2001/sw/grddl-wg/doc29/schedulequery.rq Also, the 3 repeating FILTERS are ugly for a tutorial but I can see no way around. The results are (using ARQ): ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | start1 | stop1 | loc1 | summ1 | summ2 | summ3 | ========================================================================================================================================================================================================================================================================================================================================================================= | "2007-01-08" | "2007-01-11" | "Edinburgh, UK" | "pick up a lifetime\n achievement award from the Web Design Conference" | "Web Design Conference"@en | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | | "2007-01-08" | "2007-01-11" | "Edinburgh, UK" | "pick up a lifetime\n achievement award from the Web Design Conference" | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Design Conference"@en | | "2007-01-08"^^xs:date | "2007-01-11"^^xs:date | "Edinburgh, UK"@en | "Web Design Conference"@en | "pick up a lifetime\n achievement award from the Web Design Conference" | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | | "2007-01-08"^^xs:date | "2007-01-11"^^xs:date | "Edinburgh, UK"@en | "Web Design Conference"@en | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "pick up a lifetime\n achievement award from the Web Design Conference" | | "2007-01-08"^^xs:date | "2007-01-11"^^xs:date | "Edinburgh, UK"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "pick up a lifetime\n achievement award from the Web Design Conference" | "Web Design Conference"@en | | "2007-01-08"^^xs:date | "2007-01-11"^^xs:date | "Edinburgh, UK"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Design Conference"@en | "pick up a lifetime\n achievement award from the Web Design Conference" | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It would be better for the results just to be one row, not six, as users may run this at home and get confused, as in: | "2007-01-08"^^xs:date | "2007-01-11"^^xs:date | "Edinburgh, UK"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Conference"^^<http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral> | "Web Design Conference"@en | "pick up a lifetime\n achievement award from the Web Design Conference" | -- -harry Harry Halpin, University of Edinburgh http://www.ibiblio.org/hhalpin 6B522426Received on Wednesday, 20 June 2007 01:10:19 GMT
