ACTION: ericp to draft lang-match design, summarizing and citing RFC3066

I've drafted (1.502) an exciting new section with this proposal in it:½ sop:langMatches

Returns whether the first argument is the same as, or a sublanguage of, the second argument per Tags for the Identification of Languages [RFC3066] section 2.5, "Language-range".

 langMatches("en_US", "EN")

@prefix dc:       <http://purl.org/dc/elements/1.1/> .

_:a  dc:name         "That Seventies Show"@en .
_:a  dc:name         "Cette Série des Années Septante"@fr-BE .
_:a  dc:name         "Cette Série des Années Soixante-dix"@fr-FR .

This query uses langMatches and lang (described in section find the French names for the show known in English as "That Seventies Show":

PREFIX dc: <http://purl.org/dc/elements/1.1/>
SELECT ?name
 WHERE { ?x dc:name  "That Seventies Show"@en ;
            dc:name  ?name .
         FILTER ( langMatches( lang(?name), "FR" ) ) }

Query result:
"Cette Série des Années Septante"@fr-BE
"Cette Série des Années Soixante-dix"@fr-FR

I had fun looking for an example where country codes would matter.
