It describes how clients interact with social services and how independently operated servers exchange activities, enabling federated publishing and social interactions. The official specification is useful for developers building compatible social platforms or understanding federation. It defines the protocol rather than operating a social network or providing a ready-made application.","updated":"2026-11-03","link_checked":"2026-11-03","search_context":{}}
