It is with great pleasure that I can share the following two standards documents that were finalized this past week under the Fediverse Enhancement Proposal process:

FEP-400e: Publicly-appendable ActivityPub collections “describes how ActivityPub servers and clients could specify collections to which objects created by their actors belong.”

FEP-8fcf: Followers collection synchronization across servers “describes an optional mechanism for detecting discrepancies in following relationships across instances, with minimal overhead and without loss of privacy.”

It is hoped that documents like these can form the basis for greater interoperability between services on the fediverse.
