Come Jena3, absolutely!
If we wanted to make this functionality extensible by end users (but I
don't see this being a common use case), that is also addressed by
having the enum extend an interface (Effective Java Item 34).
[ Stephen is referring to:
public enum BasicThing implements Thing { }
and extend Thing, not the enum itself. ]
I agree, not a common case, although maybe dispatching on the Lang in a
switch statement is the key useage for an enum and then it's an internal
matter. Usually, it's just a symbol to label things.
The cases I can think of are JSON-LD, RDFa, GRDDL (?? has other
requirements; you have to know it's a GRDDLable document really).
If it's a fixed(ish) list, we can just add everything into the enum and
be done.
