A few weeks back we quietly released the first snapshot of the current generation of the Peruser framework.
There's still lots of work to be done, but it's coming along nicely. It is quite usable today for basic SPARQL queries under Cocoon. To set up more complex queries (including dumps of taxonomy trees, using the Projector module), you will have to wade through some incomplete documentation and probably look at the code.
During development of this code over the last few years, one of the things we discovered mid-stream is the potency of the Jena Assembler framework. We have been weighing the costs and benefits of dumping some Peruser configuration features in favor of using this framework.
We are also trying to generate some public discussion of the best way to structure the relationship
between Assembler (and other RDF) artifacts and Cocoon artifacts in this new discussion group,
which y'all are invited to join: Cocoon as a Semantic Platform
