ote Operations Service Element (ROSE) is a sub-layer of protocol layer six (presentation layer) in the OSI seven layer model which provides SASE for remote operations.It is "a very general client-server mecanism, which hides from the application programmer the existence of a communication between processes; it can ask the remote application to execute operations or to collect results and errors; each interface's operation is described with ASN.1 as an information object of the OPERATION class; ROSE provides a common and standardized method for carrying requests and answers laying by specific gaps in the APDU to be filled in dynamically during communication" - From the freely available book "ASN.1 - Communication between heterogeneous systems", by Olivier Dubuisson
