Today, I am pondering over the alsoKnownAs predicate (in relation to my fully RDF-aware ActivityPub server Vocata).
The (tbh, non-normative) ActivityStreams ontology refers to DID Core, so I read this as the predicate being imported from there. However, looking at the DID ontology, it states that the alsoKnownAs predicate is in the ActivityStreams namespace.
How do I read this? I understand this as the predicate being under the AS namespace technically, but semantically defined in DID Core. Is this the correct interpretation?
Yes, and it gets a bit more confusing, because the definition adopted by DID Core conflicts with the actual implemented usage of the property by Mastodon. See Defining alsoKnownAs - #30 by trwnh for more discussion on this.
