Okay… is the plan to, over time, add the properties and classes which allow description of an entire certificate?

_:cert a cert:Certificate ;
    cert:subject "CN=example.com,C=GB"^^cert:DistinguishedName ;
    cert:issuer "CN=Joe Bloggs,O=Widgets PTY,C=AU"^^cert:DistinguishedName ;
    cert:notBefore "2010-01-05T00:00:00Z"^^xsd:dateTime ;
    cert:notAfter "2012-01-04T23:59:59Z"^^xsd:dateTime ;
    cert:subjectKey _:key ;
    cert:extension _:basicConstraints ;
    cert:extension _:subjectAltName .

_:key a cert:rsaPublicKey ;
    ... .

_:basicConstraints a cert:Extension ;
    cert:extension <oid:2.5.29.19> ;
    ext:CA "false"^^xsd:boolean .

_:subjectAltName a cert:Extension ;
    cert:extension <oid:2.5.29.17> ;
    ext:URI <http://example.com/me#id> ;
    ext:IP "169.254.0.1" .

?

[I won't get into the thorny issue of comparison between RDF graphs and canonical DER form, comparing signatures, etc., etc...]
