Could you make this change so that the results match > the case of the data, Eric? I think it's best if i change the input data. It could be argued from [[ Plain literals have a lexical form and optionally a language tag as defined by [RFC-3066], normalized to lowercase. ]] -- http://www.w3.org/TR/rdf-concepts/#section-Graph-Literal that the normalization should go to LC. However, I don't want to change, or even help, the world at this point. So let's just go with lower case test data. all "-DE" strings changed to "-de" q-langMatches-de-DE.rq moved to q-langMatches-de-de.rq manifest updated > thanks, > Lee -- -eric office: +1.617.258.5741 NE43-344, MIT, Cambridge, MA 02144 USA mobile: +1.617.599.3509 (eric@w3.org) Feel free to forward this message to any list for any purpose other than email address distribution.
