Hm, maybe 
but i'm still confused, because there is defined:
a) "owner": {"@ID": "sec:owner", "@type": "@ID"},
b) "publicKey": {"@ID": "sec:publicKey", "@type": "@ID"},
means (as i understood)
a) 'owner' is -> https://w3id.org/security#owner
b) 'publicKey' is -> https://w3id.org/security#publicKey
but i cannot find a definition for https://w3id.org/security#owner & https://w3id.org/security#publicKey
the owner attribute idea maybe comes from here:
A decentralized social networking protocol based upon the ActivityStreams 2.0 data format and JSON-LD.
(docs.joinmastodon.org)
the sample is strange, i cannot find one of this properties:
https://www.w3.org/ns/activitystreams#publicKey
https://w3id.org/security/v1#publicKey
https://w3id.org/security#publicKey
https://www.w3.org/ns/activitystreams#owner
https://w3id.org/security/v1#owner
https://w3id.org/security#owner
currently i'm confused a bit. a few month ago i talked to the community about publicKey in the actors profile.
I think @steve was answering, that the property publicKeyPem has the namespace https://w3id.org/security#.
i'm using https://w3id.org/security#owner, but forgott, ehere i've found that info. it looks like that https://w3id.org/security#owner is not existing.
Is there a valid document that describes that publicKey stuff ?
