The modeling of physical and logical network resources provides the main interface to network management software applications. The object-oriented information model defined in the OSI managment framework provides notations to specify such interfaces. This framework has been recently extended with a relationship model. Relationship modeling adds informations upon isolated object specifications and offers new services for the management of these relationships. In this paper, we address some practical issues on network management architectures. To implement this new model, we start from relationship specifications up to the provision of a relationship service within the manager role of a managment system. Our study outlines some lacks in the standardized relationship model and extends the notations with new statements to allow the development of a generic relationship provider. We also present a simple prototype that works on our Managed Object Development Environment. This prototype is a first implementation towards a complete tool for relationship management.
