Re: [JSON] RDF collections and JSON arrays

I agree that having a syntactic sugar for lists would be a good thing, similarly to what Turtle already has.

The problem is that the list syntax of JSON, ie, '[...]' is would be very useful for cases when we'd want to define shortcuts. Eg, the equivalent of 

:a :b :c, :d .

in Turtle would make use of something like '[ :c, :d ]' and I am not sure there is an alternative for that.

So no, it is not trivial nor obvious... Hence the slightly ugly

[[ :c,:d ]]

proposal that came up on the list. I would have to hold by nose looking at that, but I do not see any radically different alternative:-(

Since this is supposed to correspond as nearly as possible to a LISP list, it seems it would be 'natural' for an RDF collection to map into a JSON array. And if this is to round-trip, then these arrays must be somehow marked as coming from an RDF collection so that they can be mapped back into one.

While OWL is not a prime target for our WG, it would seem to be a good idea to define a JSON mapping which does not completely screw up OWL, if at all possible.
