The ISO Reference Model for Open Distributed Processing: An Introduction

The ISO Reference Model of Open Distributed Processing (RM-ODP) consists of four parts an Overview of the reference model, the Descriptive Model, the Prescriptive Model, and the Architectural Semantics. The four parts provide the concepts and rules of distributed processing to ensure openness between interacting distributed application components. Openness is a combination of characteristics, i.e. scalability, accessibility, heterogeneity, autonomy and distribution. The RM-ODP introduces the concept of viewpoint to describe a system from a particular set of concerns, and hence to deal with the complexity of distributed systems. !" # %$& ' ( ) *!+!" # % %, ) !# % % .#/0 "!1 %23 % 45 %67 $8 4+ / 9 % : ;!< *,= > 9 ;,?45 "!# % @ % < A # ' ; B.
