XQuery/XPath functions have URIs. e.g http://www.w3.org/2005/04/xpath-functions/#max Suppose I write... PREFIX ex: <http://example/vocab#> PREFIX xfo: <http://www.w3.org/2005/04/xpath-functions/#> SELECT ?n WHERE { ?who ex:name ?n FILTER xfo:matches(?n, "Dan") . } That's a core SPARQL query, right? It works just as well as... PREFIX ex: <http://example/vocab#> SELECT ?n WHERE { ?who ex:name ?n FILTER regex(?n, "Dan") . } I don't see any text to that effect in http://www.w3.org/2001/sw/DataAccess/rq23/#extensionFunctions $Revision: 1.300 $ of $Date: 2005/04/14 11:43:04 $ I think it's worth testing too. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/ D3C2 887B 0F92 6005 C541 0875 0F91 96DE 6E52 C29E
