@evan probably that should be clarified. Should I open a ticket somewhere?

@evan @mariusor @silverpill although note that i think nightpool is of the opinion that POSTing a non-activity to the outbox is an at-risk behavior and should be deprecated, because the "implicit Create" behavior has to somehow know whether or not the body of the POST is an Activity or not, and we never actually define how to know this, so it is too likely that the server will accidentally wrap activities in a Create if some inference fails.

@evan @mariusor @silverpill re: ids though the RDF ecosystem (and jsonld) doesn't use "null", it uses blank node identifiers (those prefixed with _: are special cased by the prefix expansion algorithm). this can allow for "transient" activities or "anonymous" objects (and the graph data model auto assigns _:b1, _:b2 and so on when "id" is missing; the canonicalization algorithm assigns _:c14n0 and _:c14n1 and so on)
this is maybe not the best way to create replies collections though...

@evan @mariusor @silverpill i think we probably need to revisit the user story of creating multiple objects at once, or more accurately, the user story of minting and binding multiple identifiers at once.

@reiver i think the disjunction between Object and Link was actually unnecessary. https://github.com/w3c/activitystreams/issues/666
i also think there's too much emphasis on types when there really shouldn't be -- it's the *properties* that you end up using almost all of the time. pretty much the only types that actually matter are the Activity types (because you can't infer those).

@reiver Did you and I discuss queryfy a while ago, or was it one of my other projects?
Just wondering whether I owe you a heads up since queryfy has been bumped up to v0.3.0

With ActivityPub / ActivityStreams...
To me, it feels like there should have been something that is a common parent of both 'Object' and 'Link'.
That just had the "name", "nameMap", and "preview" fields (along with "id" and "type, of course) — since that is what 'Object' and 'Link' share in common.
I'll just call this common parent: 'Entity'.
...
It could have even been an opportunity to talk about how to handle unknown types.

@soapdog@toot.cafe hmm... just thinking aloud here.
You posit in another post that the network effects inflate exponentially:
> Push models are resource hogs that approach exponential growth in a large network like the fediverse
That's not true. If you post a message then it sends a copy to each follower. That's linear growth. If you collapse recipients via shared inboxes you can reduce that further.
If you're referring to the torrent of requests that happen if your post is shared (the "thundering herd" problem) then that's actually a PULL happening from those requesting instances!
Secondly, in a pull model of AP, you would need to continually poll servers of all your followers so as to approach a real-time effect. You'd be polling servers over and over again, and many of them would have nothing new, with so much wasted traffic.
If your expectations include semi real-time updates, the push model is much more performant, in my humble opinion.
