@silverpill @frogzone @jeffcliff @feld I haven't kept up with it. I have some notes but you can feel free to ignore them; I don't want to get in the way of some people doing a thing. Wherever it lands, I'll try to make sure that we can interoperate without breaking the FEP semantics if possible, but some places, it's not going to be possible. So, here are the notes (and quick read, so I may have missed things or I may have the wrong idea, because the stupid DDoS yesterday cost me a lot of time and I'm trying to catch up today):

> ap://did:example:123456/path/to/object?name=value#key-id

If it's a new protocol, I don't know why we're still doing a fragment for the key ID. I don't love JSON (anti-web) but we've got to live with it; on the other hand, I don't want to abuse JSON or URLs.

I'm using RSA keys so that it's easy to port myself from Pleroma. It is entirely possible that there is something I am missing and that we shouldn't be using RSA keys; maybe key algo is overspecifying.

I like this, but I wonder if there's a way around it without hard-coding another URL.

> The client MUST specify an Accept header with the application/ld+json; profile="https://www.w3.org/ns/activitystreams" media type.

This is actually objectively wrong. I don't know why this should be done rather than using the HTTP standard interpretation of "Accept:" headers. If the client doesn't include "application/ld+json" or "*/*", then you just return a 406. The way Pleroma/Masto do these things kind of shits on RFC 2616 and I really love RFC 2616. (This is why I'm not doing the terrible sniffing algorithm to differentiate between a browser and another server on the /objects/$id URLs.) If there is a good reason, maybe, but if we're tossing out the well-defined HTTP semantics that HTTP clients rely on, we can't call it HTTP.

> Portable actors

This looks roughly compatible with what I am doing; there's an ID for an actor, the network protocol is used to find the actor, etc., and then to use an AP gateway, you sign a request to be canonically located on one, the owner of that domain approves or ignores, and that's the PoT for your account as far as any other AP server knows. So your /inbox and /outbox, the server with the responsibility for delivering your posts when it sees new ones, etc.

So this section looks like it's roughly compatible with that. Instead of ordered gateways, Revolver can just send one gateway.

> Portable objects

This part, I don't know how I'm going to manage this. The "attributedTo" being tied to the gateway URLs, and then those potentially changing, that's going to be a mess with content-addressed storage. If you create a new activity by signing the head of a tree that contains pointers to objects in a stream, then those objects changing (e.g., because a gateway changed) is going to make hopping computationally infeasible once you have a long enough history (which is going to be almost all of the initial users, since they will mostly be people on FSE/bae.st that follow the move to Revolver).
