Re: Any way to specify the default URI for the @id of a @type or the values of a property.

Hi!

> What I would like to do is to specify those prefixes and keep data
telling @id = '123', with the value joins happening at RDF serialisation
stage (the same specification would make it possible to do the opposite
conversion too). Clearly, in such a use case, the prefixes depend on the
@type of objects, and the @base mechanism is not enough. Moreover, it would
be useful to have this mechanism available for properties too, e.g., to
associate the address URI prefix to the values of the "address" JSON
property.

and using namespaces (cf. example 40 in [4.11 IRI Expansion within a
Context] or [4.14 Scoped Contexts]) isn't an option for you?
