Given it also applies to #ActivityPub, can someone explain the following “ActivityStreams 2.0” requirements? (Section 2.2) “(1) when an IRI that is not also a URI is given for dereferencing, it must be mapped to a URI using the steps in Section 3.1 of [RFC3987] and (2) when an IRI is serving as an "id" value, it must not be so mapped.” Isn’t an IRI given for dereferencing always an IRI serving as an “id” value for some Object? Maybe some examples would help to clarify it?
