Hi Arun and all, Sorry for the late response, I just want to re-state my concern during the conf call earlier on the mailing-list.
My first concern is that for the data modeling, we should adopt a common denominator of different VIM implementations. This means each concept defined in the data model here should be able to correctly mapped to various VIM implementations within scope. Moreover, a good data model should represent a relationship of abstraction rather than aggregation. Take Resource Cluster Group Class for example, it merely represents an arbitrary aggregation of the Resource Cluster Group which means this concept does not provide any abstraction over underlying resource concept. Another problem is that only VMware implementation has a nicely mapped corresponding concept to RCGC, whereas in OpenStack it is just obscurely mapped to "a set of host-aggregates". And if you remove the RCG point in the diagram provided in [0], you can see that no major connection will be disrupted, which also proves as a leaf node it is not a necessary one. RCGC is something I would recommend we avoid for the data modeling of multicloud. Secondly, I'm concerned with the concept of resource slice. Again it seems very arbitrarily crafted as a subset of resource (which again I fail to see an abstraction relationship but an aggregation one). It would be great if this concept is necessary then we have a very good detailed explanation of why we need it.
