Common Domain Objects in the RM-ODP Viewpoints - Genilloud, Guy
An important standardisation effort is in progress within the Object Management Group (OMG) regarding domain computing facilities and common domain objects. In this paper, we investigate the very idea of common objects within the Reference Model for Open Distributed Processing (RM-ODP). We show that common objects are in fact common object templates, that different kinds of templates are needed for different viewpoint models, and that agreeing on common object templates is particularly useful for information modelling.

X.400 MHS: First Steps Towards an EDI Communication Standard - Genilloud, Guy
Electronic Data Interchange (EDI) is an increasingly important application of computer communications. Until recently, EDI has developed independently of the communications technology and related standards. EDI users coped with this situation by setting up bilateral communication agreements or by using the services of Value Added Data Services centres, which provided protocol conversion. The introduction of X.400 MHS based systems and services is slowly modifying the general attitude towards EDI communications. For the first time, a CCITT rapporteur group is drafting a recommendation for EDI communications within the context of X.400 MHS. More importantly, there already exist official guidelines, both in...

Formal methods for communication services: meeting the industry expectations - Hubaux, Jean-Pierre; Dietrich, Falk
We survey formal methods as they are applied to the development of communication services. We report on industrial and academic projects, consider different communication architectures and work related to the feature interaction problem. Based on our survey and on extensive discussions with the industry, we investigate important industrial concerns and criticisms about about the use of FMs for the development of communication services. We report on a collaborative project between the Swiss Federal Institute of TEchnology in Lausanne, Swisscom, Alcatel and Thomson in which these industrial concerns have bee taken into account from the very beginning. The results of this...
