Everyone in biomedical research dreams about integrated resources. I have heard multiple people advocating SPARQL as well. If it had been that easy, this would have occurred years ago. In the real world, no one is even close. If you want to attract collaborators, learn Linus: say you have a working prototype and demonstrate how wonderful it is. Your ideas are cheap. The difficult part is a clear roadmap to make it happen.
Based on what I see happening in large orgs with lots of machine learning resources is the development of new techniques to generate large amounts of homogenous phenotypic data across many measurement modalities. These large orgs have biologist/doctors: the small number of people cross-trained well enough to move between the two fields with ease. These orgs have gathered enough resources to compel the leading researchers to work with them, and they're starting to publish interesting papers.
(I know very little about the issue, but this seems to be a problem in many fields of academia.)
