ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates Enterprise Viewpoint o An enterprise specification of an ODP system is a description of that system and relevant parts of its environment. o The enterprise specification focuses on the scope and purpose of that system and the policies that apply to it in the context of its environment.

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates Part II o Committee Draft o X.906 Use of UML for ODP system specifications o The RM-ODP family of standards is notation free, as well as model development method free. o There is no widely agreed approach to the structuring of UML specifications. o ISO/IEC is technically identical to the OMG specification formal/ , UML ISO format. o As an example, the UML Profile for EDOC (using the UML extensions mechanism) provides a bridge between the RM-ODP architecture for distributed systems and specific technologies, such as components, workflow, messaging, and web services.

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates Scope a) the expression of a system specification in terms of RM-ODP viewpoint specifications using defined UML concepts and extensions (e.g. structuring rules, technology mappings, etc.); b) relationships between the resultant RM-ODP viewpoint specifications; c) relationships between RM-ODP viewpoint specifications and model driven architectures such as the OMG MDA.

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates RM-ODP viewpoints

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates Correspondences between RM-ODP viewpoints

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates MDA viewpoints and models o a computation independent viewpoint (CIM) that focuses on the requirements for the system; the details of the system are hidden or as yet undetermined; o a platform independent viewpoint (PIM) that focuses on the application specific behaviour of a system while hiding the details necessary for a particular platform. A platform independent view shows the part of the complete specification that does not change from one platform to another. A platform independent view may use a general purpose modelling language, or a language specific to the area in which the system will be used; o a platform specific viewpoint (PSM) that combines the platform independent viewpoint with an additional focus on the detail of the use of a specific platform by a system.

ITU-T ITU-T Study Group 17, Moscow, 30 March – 8 April dates Enterprise Language 7.2 UML mappings o An ODP System is a special kind of enterprise object. It maps to UML with a class stereotyped as « EV_ODPSystem », see [7.2.5]. o The scope of an ODP system is the set of behaviours that the system is expected to exhibit, e.g. its roles. It does not, therefore, map to a single UML model element, but to the set of elements that represent its behaviour. o The field of application is a property of the enterprise specification as a whole, and maps to a text attribute (comment) of the UML model stereotyped as « Enterprise_Spec » which maps to the enterprise specification. o A community maps to a subsystem stereotyped as « EV_Community », in the name space of which will be the UML model elements mapping to its roles and the associated behaviour (communications, actions, steps and processes), as well as the UML model elements mapping to the policy and accountability concepts specific to the community. o ETC
