Viewpoint consistency in ODP

Open Distributed Processing (ODP) is a joint ITU/ISO standardisation framew ork for constructing distributed systems in a multi-vendor environment. Cen tral to the ODP approach is the use of viewpoints for specification and des ign. Inherent in any viewpoint approach is the need to check and manage the consistency of viewpoints. In previous work we have described techniques f or consistency checking, refinement, and translation between viewpoint spec ifications, in particular for LOTOS and Z/Object-Z. Here we present an over view of our work, motivated by a case study combining these techniques in o rder to show consistency between viewpoints specified in LOTOS and Object-Z .
