Again the main aim is still to keep things simple for the reasons you mentioned recently on the foaf-dev mailing list - that is the more relations we support the more difficult it is to test them, and the more difficult it becomes to build applications that use these tools.

Since rsa is what ties most of the certs and in all formats together, we have simplified PGP and X509 down to what they are all based on in the end. We can always add DSA and other key formats as they really start getting adopted -- but that leaves us quite a bit of time.

Still I would not be against merging the rsa ontology into the cert ontology, given that it is so small, and that they are so closely linked. But again this comes now at a cost of people developing the webid libraries yet again.

+1 re. merge.

Also remember our chat about Cert. Fingerprint getting into mix. A 
merged ontology would be a nice vehicle for this endeavor.

Hopefully, I'll soon (maybe a week max) demo simple declaration of WebID 
patterns via blogs, tweets (you might have seen these already on Twitter 
via hastag #WebID).

Like Peter Williams, I am most preoccupied with viral patterns for 
WebID, at InterWeb scale. We have make WebID generation (including the 
full double entry bookkeeping across local keystore and public data 
spaces)  a "one click" affair across PCs, Tablets, Smartphones etc.
