Hi there, maybe sb can tell me if this is still possible: I'd like to fetch all datatype URIs used for object literals in a dataset. There is the dataset predicate which can be used in filter expressions to filter literals to a known datatype like xsd:string: FILTER(datatype(?val) = xsd:string). But can I bind the value to a variable somehow? With a filter it can't work (consider FILTER(datatype(?val) = ?dt) where ?val is bound to literal values and ?dt should give me the type). I could use property functions, but I'd like to stay with SPARQL specs. Maybe there is a way to do it I just can't see... thanks, AndyL Web of Data Practitioners Days / Oct 22-23 / Vienna http://www.webofdata.info ---------------------------------------------------------------------- Dipl.-Ing.(FH) Andreas Langegger Institute for Applied Knowledge Processing Johannes Kepler University Linz A-4040 Linz, Altenberger Straße 69 http://www.langegger.at
