I did some research into Rena, Ruby/RDF and some of the other RDF-related projects last summer. I didn't get very far with evaluating Samizdat due to the large number of dependencies; but I think it's accurate to say that it's more of an application that uses RDF, than a library (or "framework", if you prefer) for processing RDF. Dan Brickley has confirmed that Ruby/RDF is effectively a dead project, which leaves Rena, Semitar and Redland. As Aredridel hinted, Redland is certainly the most mature of the three, but it's heavily dependent on C extension code. Semitar was (is?) sort-of a hybrid of "mostly Ruby" and some C extension code. Rena was (is?) completely implemented in Ruby. All of them provide, to some degree, functionality for parsing RDF into a model and then querying that data.
