2. ITU-T/SG 17 Mar 14 20042 Open Distributed Processing (ODP) Distributed processing: Information processing in which discrete components may be located in different places and where communication between components may suffer delay or may fail.Distributed processing: Information processing in which discrete components may be located in different places and where communication between components may suffer delay or may fail. Open distributed processing: distributed processing designed to conform to ODP standardsOpen distributed processing: distributed processing designed to conform to ODP standards ODP standards: Standards that allow the benefits of distributed processing services to be realized in an environment of heterogeneous IT resources and multiple organizational domainsODP standards: Standards that allow the benefits of distributed processing services to be realized in an environment of heterogeneous IT resources and multiple organizational domains

ITU-T/SG 17 Mar 14 20043 Standardization for Open Distributed Processing (ODP) Initiated in JTC 1/SC 21 (Open Systems Interconnection, Database and Open Distributed Processing) and ITU-T SG7 (Data networks and open system communications)Initiated in JTC 1/SC 21 (Open Systems Interconnection, Database and Open Distributed Processing) and ITU-T SG7 (Data networks and open system communications) Now the responsibility of JTC 1/SC 7 (Software and System Engineering) and ITU-T SG 17Now the responsibility of JTC 1/SC 7 (Software and System Engineering) and ITU-T SG 17 Close collaboration with the Object Management Group (OMG)Close collaboration with the Object Management Group (OMG) –Reference Model of ODP is a specification framework for domain groups –OMG PAS submissions in the context of ODP standardization –ODP concepts reflected in OMG Model Driven Architecture
