Maybe I should have been more explicit M&S says: The xml:lang attribute may be used as defined by [XML] to associate a language with the property value. There is no specific data model representation for xml:lang (i.e., it adds no triples to the data model); the language of a literal is considered by RDF to be a part of the literal. An application may ignore language tagging of a string. All RDF applications must specify whether or not language tagging in literals is significant; that is, whether or not language is considered when performing string matching or other processing. -- http://lists.w3.org/Archives/Public/www-archive/2001Jun/att-0021/00-part#221 and includes an example similar to this (I've updated it, elided some bits) ------------------------------------------------------------ <?xml version="1.0"?> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/"> <rdf:Description rdf:about="http://www.foo.com/cool.html"> <dc:title> <rdf:Alt> <rdf:li xml:lang="en">The Coolest Web Page</rdf:li> <rdf:li xml:lang="it">Il Pagio di Web Fuba</rdf:li> </rdf:Alt> </dc:title> </rdf:Description> </rdf:RDF> ------------------------------------------------------------ The first question is: what triples are generated? (Ignore rdf:Alt for now!) If they are different from: ------------------------------------------------------------ _:a <http://www.w3.org/1999/02/22-rdf-syntax-ns#_1> "The Coolest Web Page" . _:a <http://www.w3.org/1999/02/22-rdf-syntax-ns#_2> "Il Pagio di Web Fuba" . _:a <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/1999/02/22-rdf-syntax-ns#Alt> . <http://www.foo.com/cool.html> <http://purl.org/dc/elements/1.1/title> _:a . ------------------------------------------------------------ Then we owe an explanation. The next question is: how do/can I get the xml:lang value? Since the above quote says "no specific data model representation for xml:lang" - the answer could be "you can't" but I'm not very happy with this. Dave
