There are multiple flavours of RDF and I think json-ld only supports a subset of one of them. Its been a while since I read the spec but I believe there are various fudges with lists, reification and datatype coercion.

Any time I get close to an RDF stack I find its a broken mess. Its complexity seems to almost guarantee incompatibility instead of interoperability.
