Yes, you can get back bnodes. But the identifier of a bnode has only meaning in the document it is contained in. Hence, you cannot ask the server anything else about this bnode, because you don't have an identifier for it that exists outside of that one document. Therefore, it's maybe better to not get back bnodes at all; except if the server is sure the client cannot ask further meaningful questions about them (for instance, when all triples about a bnode were already in the response, as is the case with lists, and some other situations as well). Best, Ruben
