It can be used for classification - the page is cached, therefore it is classified as a cached page, hence its class.

Though in that case I'd use a model such than a page cache caches a cached page which has an url and a fetched time and an expiry time etc., so that the caching has some form of context independent of the global resource.

RDF isn't temporal anyway - there's no means to intrinsically say 'it's cached now, but wasn't when it was created', so the distiction between "fixed" and otherwise isn't part of the language.
