Sounds like a good idea, although I don't know what else might be on the
menu.

So, I just learned of the "dataset dynamics" term and community last
week (from Michael), but I've been thinking about this for many years.
I got inspired and sketched out a design a few months ago, which I think
is pretty good.  I've been hoping to return to it some day soon, but if
we're talking about this Thursday, I might was well share the drafts
now.

I think for the use cases I have in mind (large scale, ad hoc, real-time
mirroring of RDF), a key requirement is constant time (per triple) to
apply deltas, including maintaining a secure hash.  I was happy to see I
could (I think) meet this with some tweaking of blank nodes.  I sketched
both a delta format (gruf) and a subscription protocol (websub), which
are separate. 

Rough specs are here:
