But, what about the non- fall-back situation where software could properly support this (when an Actor specifies a list of Service actors associated with it)‽

I think some might say, put the associated Service actors in "attachment". And, semantically I think that would work with ActivityPub, but — I have a very strong dislike with putting everything in "attachment" (and "tag"). It makes parsing difficult.

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall

Looking for an alternative to "attachment" (for properly supporting an Actor specifying a list of Service actors associated with it) —

I think using "alsoKnownAs" or "sameAs" would be a poor choice. The semantics are wrong.

For example: a Service actor might represent my mobile phone (or software on it). My phone is not me. It is something I have.

So —

#ActivityPub #ActivityStreams #AudioCall #Call #FediDev #Fediverse #VideoCall
