Hi, I'm using Soprano 2.4.2 and the Virtuoso backend to store a bunch of data and wanted to run a construct SPARQL query on it. I was a bit surprised when I noticed that the QueryResultIterator returned by my query was not a Graph iterator but a Binding iterator instead. Here's the query:
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix dc: <http://purl.org/dc/elements/1.1/> construct { ?thing ?property ?propval . ?property rdfs:label ?label . } where { ?thing ?property ?propval . ?thing dc:format "application/x-whatever" . ?thing ?matchproperty ?matchval . filter regex(str(?matchval), "Foobar") . ?property rdfs:label ?label . } Naturally "Foobar" would be replaced by a real search term and the dc:format would be a bit more specific, but you get the gist of it. Anyway, the resulting QueryResultIterator is a Binding iterator, with a single binding, "fmtaggret-" that contans the result as a string with embedded escaped tabs and newlines, instead of a Graph iterator that I could use to get at the statements in my result graph. What am I doing wrong? -- Ilkka _______________________________________________ Nepomuk mailing list [email protected] https://mail.kde.org/mailman/listinfo/nepomuk
