RFC 1085 ISO Presentation Services December 1988 Application Context: The collection of application service elements which cooperatively interact within an application-entity. Application Service Element: A standardized mechanism, defined by both a service and a protocol, which provides a well-defined capability, e.g., ROSE - the Remote Operations Service Element, which orchestrates the invocation of "total" operations between application-entities [ISO9066/2]. ACSE - the Association Control Service Element, which manages associations between application entities [ISO8650]. Object Identifier: An ordered set of integers, used for authoritative identification. Presentation Service: A set of facilities used to manage a connection between two application-entities. The fundamental responsibility of the presentation service is to maintain transfer syntaxes which are used to serialize application protocol data units for transmission on the network and subsequent de-serialization for reception. Protocol Data Unit (PDU): A data object exchanged between service providers. Serialization: The process of applying an abstract transfer notation to an object described using abstract syntax notation one (ASN.1) [ISO8824] in order to produce a stream of octets. De-serialization is the inverse process. It is assumed that the reader is familiar with terminology pertaining to the reference model [ISO7498], to the service conventions in the model [ISO8509], and to the connection-oriented presentation service [ISO8822]. 3. Scope The mechanism proposed by this memo is targeted for a particular class of OSI applications, namely those entities whose application context contains only an Association Control Service Element (ACSE) and a Remote Operations Service Element (ROSE). In addition, a Rose
