If by "properties" you simply mean RDF triples with literal objects, it is certainly fine to do that in Fedora 3.x.
Keep in mind that in your example below, you are making "kb:timestamp" and "kb:status" assertions about the _object_ "info:fedora/kb:33001", _not_ about the rel:isConstituentOf _relation_ between "info:fedora/kb:33001" and "info:fedora/kb:33000". Making assertions about a relationship would require some affordance roughly equivalent in expressive power to RDF reification, which is not a base capability of the Fedora RI at this time. --- A.
