Several requirements for storing registry data have been compiled and the backend layout has been refactored to comply. Specifically, we now store most data as blobs that are linked from repositories. All data access is traversed through repositories. Manifest updates are no longer destructive and support references by digest or tag. Signatures for manifests are now stored externally to the manifest payload to allow merging of signatures posted at different time. The design is detailed in the documentation for pathMapper.
