Hi, </chair-hat> just as I was stumbling over it something for the wish-list... We need datetime-difference for some use case. Was that ever considered in previous discussions in the functions-library? I am looking at the XPath arithmetics delegation in Table "SPARQL Binary Operators" in Section 17.3 of the query doc, cf. www.w3.org/TR/sparql11-query/ It's probably too much of a burden to add it now, but "nice-to have" for my use case would be 1) delegating "-" to op:subtract-dateTimes ( http://www.w3.org/TR/xpath-functions/#func-subtract-dateTimes ) For xsd:dateTime - xsd:dateTime 2) delegating "+" to op:add-dayTimeDuration-to-dateTime for either xsd:dateTime + xsd:dayTimeDuration or xsd:dayTimeDuration + xsd:dateTime Best, Axel -- Dr. Axel Polleres Siemens AG Österreich Corporate Technology Central Eastern Europe Research & Technologies CT T CEE Tel.: +43 (0) 51707-36983 Mobile: +43 (0) 664 88550859 Fax: +43 (0) 51707-56682 mailto:axel.polleres@siemens.com
