I believe the issue with XRDS is that it works fine for programmatic discovery of endpoints. The prefetch/pipelining syntax is declarative and therefore if we choose the REST URL syntax it would require that the referenced endpoints be stable and cross-container compatible. Im don't know how close the URL structure of MySpaces REST APIs matches that in Shindig for example but Im guessing there are some incompatibilities. As John mentioned and I alluded to on the other thread there was a proposal to standardize on a URL format for REST that was cross-container compatible without the need for XRDS. but it didn't see much traction. Would MySpace be amenable to this? If not then we are left to choose between the RPC format or something new.
