Hisaharu-san, Romain and Eric Thank you for your reply. I try to refer the doc Eric has given us.
Initially, there would be some ways to define a set of generic APIs. My idea is to make categories to have an overviews. Each category, for example, would be linked a use case in the blue print. Then, we can go down to details in each category. As for general criteria, > - any operation called by the compute service (Nova) directly > MUST belong to the generic API; I have the same understanding. Because the generic APIs drawn with green box are called by Nova APIs.
