I'll look at it.

It's an thing that returns a typedLiteral when adding a type, a plain
literal when adding a language and which dynamically convert to xsd:string
typedLiteral, don't see wha's wrong with "builder".

The new syntax is with a ":"-method on the new Language class?

Right, that's why there is this dynamic conversion from String to
LiteralBuilder. Because you can apply a language or a type to a String and
