FEP Convergence (400e, 7888, 171b/Conversation Containers, 76ea)

@[email protected] whether we decide to use as:context or not to represent second-order collections is still to be determined, but we can hold off on that until we figure out first-order collections. I'm not saying we hold off on it for years, just months.

FEP 7888 doesn't disallow other uses of context. It just gives direction for implementors who wish to use it to represent a first-order collection of objects. The key here is whether that context is resolvable to a collection, and (maybe) whether that collection contains items of interest (as:Note-like objects or otherwise).

The ForumWG with input from other interested parties (@[email protected], @[email protected], among others) have provided an oral history that suggests that as:context is effectively unused, and what usages are found in the wild already conform to FEP 7888.

Do I think as:audience is the solution to second-order collections? No. It's just the way it is now, but not the way it will be forever.

@julian @scott @trwnh depending upon how strictly you interpret the SHOULDs of 7888 we can approximate that 1% of posts today are using context per 7888, assuming post count is proportional to user count

@erincandescent @scott @julian i wonder if it makes sense to define something akin to conformance profiles or compliance levels? i held off on doing this because there aren't any MUSTs in there, but you could loosely say the following:

a "level 0" producer doesn't use context
a "level 1" producer uses an opaque id
level 2: it resolves to an object
level 2.1: it resolves to a collection
level 2.2: it resolves to a collection with an owner
level 3: sending objects to the owner may add them

@erincandescent @scott @julian mastodon etc are "level 0", pleroma/akkoma are "level 1", nodebb and discourse are somewhere around 2-3

@trwnh @scott @julian 1.5. the ID isn't dereferencable but could be (Pleroma & Akkoma are here)

Do we need to indicate whether you can follow a context, or would that be specified elsewhere?

@scott @julian @trwnh general rule: you should be able to follow anything which has an outbox and inbox

(The inbox is necessary to send the follow activity to)

So, since it is not declared, we would need to check to see if the context has an inbox and outbox.

And since it is not declared, we would have to check to see what traits a particular context has.

And since it is not declared, we would have to make assumptions about whether a context is a thread (conversation container) or not.

It seems like we are doing a lot of checking when the sending platform could just tell us that information.

Sure, we can't assume they will provide that information, but if they tell me up front, that is one less server query I got to make since an if then statement can make that extra query go away.

@scott @julian @trwnh I'm not sure I completely follow the specifics of what you're trying to discuss here, but ActivityPub is duck-typed: if it quacks like a duck, it's a duck. If it has the endpoints you need to follow it, you can do so.

If a post has an inbox and an outbox, you can follow it. If a picture has an inbox and outbox..

Scott M. Stolz

Something like this:

{
  "@context": "https://www.w3.org/ns/activitystreams",
  "thr": "https://purl.archive.org/socialweb/thread#",
  "thread": {
    "@id": "thr:thread",
    "@type": "@id"
  },
  "root": {
    "@id": "thr:root",
    "@type": "@id"
  }
  "traits": {
    "traits": "inbox, outbox, conversation, amendable"
  }
}

This would let me know that it is a thread and that people can follow the context. I can then render it as a thread and potentially add a follow or subscribe button for the context.

You could also declare that it does not have an inbox and outbox, which saves me the trouble of checking myself.
