before I will forget it, for the log also the text by Chris Moser about implementation and to mastodon federation workaround:
yuforium federation: Federating Communities
The ActivityPub specification provides a context field, and Yuforium adds a /topic endpoint to provide a shared context for federated communities.
Before we begin, let’s clarify that:
Yuforium is code and standards, Yuforia.com is a service
@context is not the same as context
Post to a forum from your Activity Stream by addressing the forum
{
"@context":"https://www.w3.org/ns/activitystreams",
"id":"https://mastodon.social/cpmoser/note/some-id",
"type":"Note",
"name":"First Post by Chris",
"content":"Hi world!",
"to":[
"https://www.w3.org/ns/activitystreams#Public",
"https://yuforia.com/forum/anything"
]
}
A new Note is created in the forum, referencing the original via “delegatedFor” and adding the default context of the forum
{
"@context":[
"https://www.w3.org/ns/activitystreams",
"https://yuforium.com/community/v1"
],
"id":"https://yuforia.com/forum/anything/note/another-id",
"type":"Note",
"delegatedFor":"https://mastodon.social/cpmoser/note/some-id",
"context":"https://yuforium.com/topic/anything"
}
It’s not necessary to pass through the delegatedFor property through the community at large but it should remain with the forum’s Note.
You can also POST directly to the forum outbox like your own and it will be excluded from your Activity Stream (should require authentication)
{
"type":"Note",
"name":"A note",
"to":[
"https://www.w3.org/ns/activitystreams#Public"
]
}
Forums encapsulate the context
{
"type":"Service",
"name":"The anything community",
"summary":"Representation of /topic/anything on a specific site",
"context":[
"https://yuforium.com/topic/anything",
"https://yuforium.com/topic/general"
]
}
Resource Types TL;DR
A topic is a focal point (purpose) for information exchange
A forum is a public endpoint on a server and distributes content with other forums and the larger community
A community is an ephemeral representation of all forums that are joined together by a topic
Topics
Topics are the glue that forums use to share information. They can be considered loosely authoritative entities for the context that they represent:
{
"id": "https://yuforia.com/topic/anything",
"summary": "Only ANYTHING can be discussed here"
}
The concept of authoritative entities may go against the idea of federation, therefore:
Forums can have multiple contexts
Forums aren’t required to follow the rules of their respective contexts - the caveat is that other forums (or the authoritative topic) may see them as “unofficial” or unvetted participants.
A topic can be completely unauthoritative, for example:
{
"id": "https://yuforia.com/topic/anything",
"context": {
"name": "anything"
}
}
Without an authoritative context, however, a forum will need to manually follow another forum to distribute content.
Forums
Forums are conduits to the larger, distributed community. They are endpoints that can be a source
Private Communities
We could use public key encryption to pass content around.
