Strictly speaking, "we" being "Digital Bazaar, Inc."

It does need defining, yes.

My point was that the library-based on-the-wire format is far more
malleable than the "JSON as RDF" on-the-wire format because the
library-based approach means that the developers never have to see the
on-the-wire format. So, it does need defining, but we don't have to be
as careful with the library-based on-the-wire format as we do with the
"JSON as RDF" on-the-wire format.

Correct.

Yes, that's correct.

The "good solution for the library case" is not automatic - but that's
not what I was saying. I was just stating that there would be /a/
workable solution that was automatic and that the reverse was not true.
Having a good solution for the library case does not automatically mean
that there would be /a/ solution for the "JSON as RDF" use case.

It comes from the publisher.

I don't follow. What do you mean by "It's not going to look like if..."?

We were calling it "application/json-ld" - :P

Maybe... but if it were there, we wouldn't be having this conversation -
which is a very good conversation to have. I'm always wary of groups
where, when an idea is presented, there is just a bunch of agreeable
nodding. I think we can safely say that is not happening here - and I
see that as partly a good thing. It forces us to examine each others
viewpoints before proceeding.

The RDF Web Apps WG was just re-chartered... I don't think the W3C team
wants to re-charter it yet again.

Frankly, I don't care where the work gets done... as long as it gets
done. I'd rather it happen in this group with a handful of people that
are critical of it, than in the RDF Web Apps group with a handful of
people that want to see the work happen.

The starting point was merely meant as a proposal - not attempting to
jump any decisions. It's merely another feeler out to the group. I find
it's easier to make decisions like this when there are a few solid
proposals on the table. I think we have at least one proposal for the
"JSON as RDF" work starting point now. I don't know if we have one such
thing for the "RDF in JSON" work starting point. Would someone care to
create one (or more) such proposals?
