I need a RDFS Parser/Validator

Hi,

I am looking for a appropriate RDFS validator, which is able to have the
following abilities:

1. It should validate a defined RDF vocabulary (RDFS), whether it
satisfies the RDF Schema specification, which has been recommended by
W3C.
2. It should give a report about the classes and properties.
3. It would be nice, if the validator could validate some instances
against a given RDF vocabulary (RDFS).

freundliche Gruesse / best regards
