BTW I think I found a bug: String b = "http://datypic.com/fraf1";; Literal a = (Literal) ResourceFactory.createTypedLiteral(b, XSDDatatype.XSDanyURI); System.out.println(a.getDatatype()); System.out.println(a.getValue().getClass());
a = (Literal) ResourceFactory.createTypedLiteral(URI.create(b)); System.out.println(a.getDatatype()); System.out.println(a.getValue().getClass()); Output: Datatype[http://www.w3.org/2001/XMLSchema#anyURI -> class java.net.URI] class java.lang.String Datatype[http://www.w3.org/2001/XMLSchema#anyURI -> class java.net.URI] class java.net.URI Shouldn't both getValue() be java.net.URI? I guess this needs to be fixed as in both cases the DataType indicastes it's an URI, so when casting the String to URI the system complains ;) Regards, Jorge On 12/01/2017 10:48, George News wrote: > > On 12/01/2017 9:58, Chris Dollin wrote: >> >> >> On 12/01/17 08:41, George News wrote: >>> >>> >>> On 11/01/2017 18:17, A.
