within a standards development community, across standard develop-
ment communities or within a specific enterprise architecture. A subset
of the ODP enterprise language is used.
The Enterprise Conformance and Compliance Framework (ECCF),
which provides an organizational framework in which interrelated e-
health architectural artefacts are categorized by content. It is used
to define conformance and compliance statements, and is based on the
treatment of conformance in the RM-ODP.
16.3.3 Use in Other Standards
In previous chapters, we described the main members that make up the
ODP family of standards. However, the influence of the ODP work is not
limited to this and, in addition, the ODP framework has also been used by a
number of other ISO projects.
The most prolific field of application has been in the ITU-T work in sup-
port of management of their transport networks. The recommendation G.851,
Management of the Transport Network [25] and a family of twenty-five associ-
ated recommendations dealing with different facets of management informa-
tion are all built using the ODP framework. Related work is continuing within
ITU-T Study Group 17 , concerned with Question 13/17 on Formal Languages
and Telecommunications Software.
An example of use in a quite different area is the standard ISO/TS 17573:
Systems Architecture for Vehicle-Related Tolling [20], which is currently being
revised after seven years of use. It uses the ODP reference model to provide
an architecture, a standard vocabulary and a modelling approach that allows
the system to be seen from different viewpoints, covering a wide range of
requirements, from hardware components and network protocols or interfaces
to enterprise roles and general policies of the system as a whole. This is
accomplished by applying different sets of concepts and terminologies that
make up the viewpoint languages. A complete description of a real system
is only achieved when all the viewpoint models are present. This allows the
experts in vehicle automation to achieve a clear separation of concerns and
gives an easier way to define conformant systems.
Another example can be found in the standard ISO 19119: Geographic
Information Services [21], which provides a framework for interoperability of
products involved in the access to and processing of data in geographic infor-
mation systems. This uses the ODP viewpoints to structure the framework,
and has chapters explaining the domain-specific detail associated with each
of the ODP viewpoints. Service composition is based on the computational
specification, and semantic interoperability on the information viewpoint. The
result is a modular, service-oriented toolkit for the construction of workflows
involving data repositories for geographic information associated and analysis
systems.
