FEP Convergence (400e, 7888, 171b/Conversation Containers, 76ea)
-
@julian @scott at best, a dedicated type like ConversationContainer can hint that it was produced by some producer following the ConversationContainer spec/fep/whatever, but the problem is that a) anyone can claim that type without following the spec, and b) it's not actually needed for processing the context property, because you already know it is semantically the context -- the origin or purpose of that object. if it's an id, you group by that id, and if it's a collection then you fetch items
-
@julian @scott basically if 171b wants to define a ConversationContainer type to signal that a producer is following that fep/spec/whatever then they can do that. i maintain that the use of `target` is still incorrect, invalid, and redundant, but it is what it is. if a similar/different fep defines some other type to signal basically the same thing except in details, then that can also be done. in the end, i would advise that the actual "protocol" doesn't require hardcoded type checking.
-
@julian @scott in any case the algorithm for processing the post as a topic owner is:
1) loop over `context` for any ids you own
2) if the post is acceptable to you, add it to the relevant collectionthe algorithm for processing the post as a third-party observer is:
1) look at `context` to see if any of them are collections
2) pick a collection and navigate to it, discarding the post. if it's actually in the collection, you'll see it again. -
@julian @scott that's basically what this all boils down to, really -- not a technical change, but a social one.
our softwares should stop trying to reconstruct shadow collections based on what they *think* should be in there, and they should just browse to the actual collections.
in general, more things should work like web browsers instead of blackboxes that gobble up data and mash it together based on their best guess of how they think it's connected.

@julian
If, for example, someone were to see my context and say "I'd like to map this context's objects out into a word cloud and do sentiment analysis on it", I think that's a perfectly cromulent use of the data. For me to say "this here is a thread, and you better treat it as a thread" is contrary to the spirit of ActivityPub and fedidevs in general.
Simply declaring a collection to be a thread does not force people to display it as a thread. But it does provide valuable information to people who do want to display it as a thread.
So you are not removing people's choice by simply stating that on your platform, this is considered a thread. -

That is my point. If you tell me what the thread is, I can download all of the posts within that thread. I don't even have to parse the reply tree at all. -
@[email protected] @[email protected] I'm at a loss as to why you seem to think this is not possible if the property is called
contextinstead ofthread. -
@julian @infinite love ⴳ As I said before, with platforms like yours, which only have one context, I can assume that one context is the thread.
Declaring which one is the thread is only necessary if you have multiple contexts.
But, I am thinking of other use cases where the context might not be a thread, or there are multiple contexts. In that case, additional clues would be very useful.
The reason why I think we should declare threads as threads is for two reasons:
1. It anticipates future use cases that are different from our own.
2. People tend to copy other people's implementations, and we have an opportunity to set the standard and be the example for others to follow.
So, no, you don't need to declare it a thread in your current implementation. But you may have to make changes later when projects start implementing multiple contexts and they don't conform to your assumptions about contexts.
It is always better to explicitly state something than to force people to guess. -
@julian @trwnh @evan @jenniferplusplus @mikedev @scott @erincandescent @trwnh What if we use
contextfor activities andthreadfor posts? -
@silverpill @scott @julian @evan @mikedev @jenniferplusplus @trwnh @trwnh the context property is in the objects, not the activities

@[email protected] said in FEP Convergence (400e, 7888, 171b/Conversation Containers, 76ea):
It is always better to explicitly state something than to force people to guess.
Partially agreed, but in this case I'd feel better about encouraging implementors to move toward a generic representation of object collections, with the potential for a more straightforward way of defining thread-like actions.
Let's take @[email protected]'s example of thread forking. You can already express this using existing activities:
as:Removethe forked posts out of theas:context,as:Addthem to a newas:context. Maybe sprinkle in anas:Announceor something (I read that somewhere...)Or perhaps a locked thread:
as:contextowner sendsas:Rejectand does not federate out anas:Addto followers.We could definitely go down the road of designing a bespoke property with associated actions, but I feel like the ActivityStreams vocaulary is fairly expressive, if vague at times... that movement against vagueness is exactly what FEP 7888 is all about.
We don't know future use cases, and there may be cases in which these decisions look wrong in hindsight, but I'd wager that being too explicit is premature, and an approach that is generic enough to express more is better.

@[email protected] How to handle multiple contexts is indeed a topic that is well worth visiting. I hear you when you say that given multiple contexts, you don't know which one is the thread. I don't have the answers today, but I want to set the framework so that when we do find the answer, we won't be hamstrung by a past decision.
Right now my thinking is that if you have multiple contexts:
- You might not need to use multiple contexts (
as:contextfor the thread,as:audiencefor the collection one level higher) - We should recommend that contexts be ordered from narrowest scope to widest
That ought to handle practically all situations (ready to take my words back on this one hah!)
The one sticking point would be situations where an object is part of multiple contexts at the same scope, e.g. a software that lets you
inReplyTomultiple context-independent objects. In that case, not even @[email protected]'sthr:threadproperty would help because we'd want to set two threads there too! Now we're back at square one.So at least for today, we can probably safely declare that if multiple contexts are defined, and they both/all point to resolvable collections, you could treat them all like thread-like data structures, if that's your software's thing.
- You might not need to use multiple contexts (
-
@julian I see what you are saying, but you can't assume that collections are thread-like data structures.
In fact, one of the use cases I am looking at is creating a collections of threads, and each of those threads would have comments.
So you would have something like this:
- Project Collection
- - Thread
- - - Top Level Post in Thread
- - - Comment
- - - Comment
- - - Comment
- - Thread
- - - Top Level Post in Thread
- - - Comment
- - - Comment
If you displayed my collection of threads as a thread, it would look like a jumble of unrelated posts because it would be a jumble of unrelated posts. Each thread in the collection would need to be displayed as its own thread, not one giant thread with all posts in it.
To parse something like this, I think I would need to specify which collection is the thread, even if other platforms do not use that field.
Maybe there is another way to do it without parsing the reply tree, but I am not sure. After all, I want the moderated version of the thread, not the reply tree. -
@erincandescent @scott @julian @evan @mikedev @jenniferplusplus @silverpill @[email protected] it could be either and/or both. it’s really up to you what you declare, and what the collection owner decides to Add. i think there’s a missing piece for signaling the expected shape of what might get added — e.g., “object must have content, attributedTo must be in the audience, etc” but ultimately the collection owner reserves the right to add“unrelated” objects.
-
@erincandescent @scott @julian @evan @mikedev @jenniferplusplus @silverpill @[email protected] for example, even a conversation/thread ostensibly bound by context, where every object is expected to share the same “context”, might not actually require this! for compatibility reasons, it may be enough to simply reply to a post with context, if that reply has no context. (if it sets a different context, that’s a clear signal it’s meant for a different thread.)
-
@erincandescent @scott @julian @evan @mikedev @jenniferplusplus @silverpill @[email protected]
example 1: nodebb sets a context, mastodon is unaware and replies to nodebb. the reply has no context set. nodebb may want to Add this object anyway? this is an implementation decision based on missing information.
example 2: discourse Moves 6 posts into a new context. to keep anyone following old broken links in the loop, they Add the Move to the context.
-
@infinite love ⴳ True. With incoming posts, you will need to decide how to handle missing information, and decide if it goes into a certain context or thread.
After processing incoming activities and posts, the collection is amended, as appropriate. And internally, you may mark these as part of the context or thread in your own database to make it easier to query.
But one thing is unique about forums: It redistributes the posts to its members. So all outgoing posts sent by the forum could have the appropriate context(s) attached to it.
Since the collection has already been constructed and amended after processing new activities, that collection now becomes the de facto representation of what is in the context or thread according to the collection owner.
So, you have a choice. You can process each post individually and build your own shadow collection, or you could query the existing collection.
Or put another way, do you want to organize the conversation yourself, or do you want to delegate that to the forum or owner of the conversation container.
Option 1 gives you more control over the presentation and organizing of the incoming posts. Option 2 adds an additional layer of moderation that can potentially weed out spam, trolls, and off-topic posts.
There is more than one way to process the same information.

> one thing is unique about forums: It redistributes the posts to its members
this is done via Add or Announce, not by redistributing objects directly, and not by modifying them to inject a `context` property (which is unauthorized)
> you have a choice. You can process each post individually and build your own shadow collection, or you could query the existing collection.
the socially correct thing to do is the latter.

@infinite love ⴳ There are some interesting things you can do with context & thread information.
Display a Collection of Threads
You could display it blog, list, or grid style, with it only showing the top level post, and showing how many comments there are. To see the comments, it will either expand or take you to a new page when you click or tap on it.
You would need to know which collection is the thread to do something like this.
Drop or Collapse Moderated Posts / Comments
If you are following the forum, when the forum redistributes the posts, it tells you the context, and sends activities related to posts within their context (collection). And, ideally, you can backfill the conversation by querying the collection associated with that context.
You can take advantage of the forum's moderation by suppressing or collapsing posts that do not appear in the forum's collection. For example, some platforms will collapse a comment if it has too many downvotes. We could display a comment a similar way if it is not part of the moderated version of the thread (the collection). Users can still read it since it is part of the reply tree, but it is collapsed since it was moderated out of the thread. You can also be more aggressive and drop replies that are not part of the moderated thread.
You can also make exceptions. For example, if a user is following both the forum and an individual user, their posts would appear in your rendering of the thread uncollapsed, even if their post was removed from the collection by the forum.
And this is just two presentations I am thinking of off the the top of my head. There are more ways to display collections.
So, yes, you would still need to process incoming posts, but if information about the thread is provided, additional ways of displaying the information become possible.

@infinite love ⴳ
the socially correct thing to do is the latter.
Is it though? This is the philosophical differences I was referring to earlier.
If someone brought illegal contraband into my home, I have every right to remove both the person and the contraband.
It is similar with forums and conversation containers. If someone posts spam or illegal content, the container owner has every right to remove said content.
As someone who follows a forum, I expect the forum to moderate the content and remove spam and illegal content.
It also becomes a reputation issue. If the forum redistributes spam and illegal content, it can get blocked or shut down.
And nothing about this is forcing you to display the conversation the way the forum does. If you want to process the reply tree, then process the reply tree and create your own shadow collection. That is the freedom of the fediverse. You get to process incoming posts however you want.
But I also have the right to process incoming posts according to my preferences and/or the preferences of the users. You shouldn't infringe on my right to display the moderated version of the thread, just as I shouldn't infringe on your right to display the unmoderated version of the thread.
All of the examples that I gave can be made user configurable. So the end users can decide whether they want the moderated version of the thread or the unmoderated version. So it isn't just about my preferences. It is also about our users preferences.
