You seem to have something more than that in mind. Someone comes in saying that Errol's review is misfiled? Then Errol fixes his review? What exactly is the full story?

Here's another related story. It is semi-fictional!

Someone hacks the server hosting a popular RDF vocabulary. Let's say
FOAF. They add malicious triples to the RDF/XML schema.

Let's say the RDF/XML is (as it used to be) PGP-signed with each
legitimate update. This allows applications that choose to merge or
layer key schemas into their trusted environments, to check whether
they're happy to do so.

Does the notion of g-snaps help articulate what is happening here, and
encourage application developers to avoid open-endedly trusting
whatever they find at namespace URIs?
