What's the lang argument? Where does it come from?
There is a distinct Language object for each Wikipedia language. For
example, one for zh and one for zh-yue, although the ISO code for the
latter is mapped to zh. Language.get("zh-yue") will return a different
object than Language.get("zh").
But: Quad.scala uses only the ISO code. That's why triples generated from
zh-yue input appear with the zh language tag. You could change the second
constructor in Quad.scala to use the Wikipedia code instead. I'm not sure,
but I think the result might be invalid according to the RDF spec and RFC
3066 in particular.
It's a known problem that some Wikipedia language codes are incompatible
with ISO language codes. There are recurrent discussions on the Wikimedia
mailing lists about this.
