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.
