Amrith, above you hit upon a critical missing piece: a *consistent*, 
*versioned* way of representing the set of resources and capabilities 
for a particular request.

Each service project has its own different expectations for the format 
of these requested resources and capabilities. I would love to get to a 
single, oslo.versioned_objects way of describing the request for some 
resources and capabilities.

I'm working on a spec that proposes standardizing the qualitative side 
of the request (the capabilities). In Nova, we're getting close to 
standardizing the quantitative side of the request (resources). 
Hopefully before too long I'll have a spec up that explains my vision of 
this unified request representation.

Best,
