activitypub —
notes about the azorius implementation
The azorius(1) server processes
activities using the ActivityPub protocol to exchange
messages with other servers. The specification is subject to interpretation,
and not all implementations behave in the same way. This document attempts to
clarify azorius's behavior. It is not intended to be a complete description of
ActivityPub, but may be useful as a guide to other
implementors looking to interoperate.
The following object or document types are supported.
