It does need some more refinement.

I see a PGP wot qualifying the public key present in a foaf card.

If a resource server receives a self-signed cert during SSL client authn, obtains attributes from a (trustworthy) network source located using the subject's name, and determines that one attribute is the public key of the self-signed cert, then it may consult the PGP key ring.

If the public key is on the pgp key ring, the key ring will compute a confidence metric for that key given the context of intended usage and the intended audience (based on some logic specific to the PGP community). If the metric passes a threshold on some scale, the resource server relies on the evidences from the various parties and proceeds to access control (as is traditional in IBAC systems for 30+ years).

If you dont like PGP or its means of computing confidence metrics, one uses something equivalent for computing a metric, such as an OCSP responder located by a URI in the self-signed cert, or one uses cert chains and CRLDPs and delta CRLs.....  One can even use a foaf graph... or a facebook/twitter "following chain".

WebID-ISSUE-45 (pgp-comparison): Compare WebId with PGP/GnuPG Web of Trust [research]

Compare what can be done and how easy it is using PGP-WOT vs. WebId technologies.

WebId offers easier weak security mechanism (replacement of email authentication), can WebId also provide high degree of security with transitive trust features?
