An institution decides that it will use the same file storage architecture for both access and preservation copies. Repository software operates on the underlying filesystem itself for both routine access (e.g., a request for an image from a IIIF server) as well as making periodic copies to nearline storage and tape backup systems. In this case, they may implement the OCFL server access pattern, differentiating between systems that provide read/write and read-only access.
