I got a lead yesterday on some OWL parsing and generation tools implemented in Lisp. Apparently in the process of being open sourced. The back-end store on their project is Sesame. I don't know if they will be releasing their triple store bridge along with the rest of the tools.
Needless to say, this is seriously exciting to me! I will switch from working on my triple store API to CL-Wiki for now. I need to write up a design document as a first step.
