Examples : retrieve a resource with "test" in english as label :
?c rdfs:label "test"@en
Retrieve a resource with a title in english :
?doc kmp:title ?t@en
Limitation : query on language can only appear on the value part (the 3rd element of the triple). Hence this is not correct : ?l@en = "Olivier".
A literal in one language is not equal to the same literal in another language. The current implementation distinguishes en-us and en (they are not equal).
