X.902 (2010 E) Not for Resale Summary This Recommendation I International Standard contains the definition of the concepts and analytical framework for normalized description of (arbitrary) distributed processing systems. It introduces the principles of conformance to ODP standards and the way in which they are applied. This is only to a level of detail sufficient to support Rec. X.903 I ISO/IEC 10746-3 and to establish requirements for new specification techniques. Introduction The rapid growth of distributed processing has led to a need for a coordinating framework for the standardization of Open Distributed Processing (ODP). This Reference Model of ODP provides such a framework. It creates an architecture within which support of distribution, interworking, and portability can be integrated. The Reference Model of Open Distributed Processing (RM-ODP), ITU-T Recs. X.901 to X.904 I ISO/IEC 10746, is based on precise concepts derived from current distributed processing developments and, as far as possible, on the use of formal description techniques for specification of the architecture. The RM-ODP consists of: ITU-T Rec. X.901 I ISO/IEC 10746-1: Overview: Contains a motivational overview of ODP, giving scoping, justification and explanation of key concepts, and an outline of the ODP architecture. It contains explanatory material on how the RM-ODP is to be interpreted and applied by its users, who may include standards writers and architects of ODP systems. It also contains a categorization of required areas of standardizationexpressed in terms of thereferencepoints forconformanceidentified inITU-TRec.X.9o3 IISO/IEC 10746-3. This part is not normative. ITU-T Rec. X.902 I ISO/IEC 10746-2: Foundations: Contains the definition of the concepts and the principles of conformance to ODP standards and the way in which they are applied. This is only to a level of detail sufficient to support ITU-T Rec. X.903 IISO/IEC 10746-3 and to establish requirements for new specification techniques. This part is n
