Denotation is handled by the HTTP URI in the X.509 Certs. SAN slot i.e, 
the WebID.

Identification is handled by the combination of claims in the X.509 cert 
and claims in the public WebID-Profile document, which you obtain by 
de-referencing the WebID in the Cert. SAN en route to the description of 
what's denoted by said WebID.

Authentication of the claims discerned from Identification occurs via 
protocols e.g., WebID-TLS, OpenID etc..

That's one component of an identity claim i.e., possession of a Public 
Key that pairs with a Private Key.

That's just denotation i.e., like a word in natural language. When you 
added Linked Data principles to the mix, the word becomes a term (i.e, 
denotation and reference duality).

Make another identity card/certificate. Cross reference the new WebID 
with the old, via an appropriate relation (e.g., owl:sameAs, 
rdfs:seeAlso etc..) .

It's ultimately all about identifiers, relations, and logic, thanks to 
the very architecture that underlies the World Wide Web.
