I have added a Parkinson's Disease (PD) information aggregation use-case on the wiki site:
http://esw.w3.org/topic/ParkinsonsDisease Currently it has disease related information on implicated genes, causes, treatments, inheritance, and pathways. It eventually is to serve as a resource for one possible scientific scenario that effectively utilizes RDF structured data (and eventually ontologies) in support of neuroscience research. Additional scientific scenarios are very much welcomed! cheers, Eric
