IEEE, Piscataway, NJ, USA,97TB100130. p 78-89 CODEN: 002753 Publication Year: 1997 Abstract: Reuse of software components available in open distributed systems is a promising approach for efficient development of complex distributed applications. In open distributed systems, type mechanisms are used both to find appropriate external software components and also to guarantee that their respective interfaces match. Furthermore, a type manager allows application developers to interactively browse existing functionality and enables the automatic mediation of compatible software components at run-time. This paper presents a uniform view for handling the functionality offered by software components regardless of context-specific aspects and a framework that allows for the automatic deduction of different flavors of compatibility relations. Finally, we describe our current type management prototype implementation. ŽAuthor abstract . 53 Refs.

Title: TELE-EDUCATION PROCESS MODELLING SUPPORTED BY THE ODP ENTERPRISE VIEWPOINT LANGUAGE Author(s): Volman, Cees; Jones, Val; van Sinderen, Marten; Widya, Ing; Michiels, Eddie Corporate Source: Univ of Twente, Enschede, Neth Conference Title: Proceedings of the 1997 1st International Enterprise Distributed Object Computing Conference Location: Gold Coast, Aust Conference Date: 19971024-19971026 Source: Proceedings of the International Enterprise Distributed Object Computing Workshop, EDOC 1997. IEEE, Piscataway, NJ, USA,97TB100130. p 2-12 CODEN: 002753 Publication Year: 1997 Abstract: This paper reports on applying the ODP enterprise viewpoint in the domain of tele-education. The work is conducted as part of a research activity that aims at designing a tele-education system to support planning, execution and evaluation of dynamic distributed educational processes. We explore the ODP enterprise viewpoint as a basis for communication and co-operation between educational scientists and ODP systems designers involved in the design process. Our application of the enterprise viewpoint involves four main steps. First, an educational language is proposed to describe educational processes in generic terms. Second, a set of appropriate enterprise language concepts is selected. Third, a relationship is established between the educational language and enterprise language concepts. Fourth, an educational process is modelled in terms of an entity-oriented model and a behaviour-oriented

model. It is hoped that the experience gained in this exercise will provide useful feedback to both the educational and ODP communities. ŽAuthor abstract . 18 Refs.

IEEE, Piscataway, NJ, USA,97CB36125. p 207-211 CODEN: CRIEET Publication Year: 1997 Abstract: This paper explains the main concepts associated with the definition of an Integrated Network Management Environment ŽINME. using object-oriented network models, and it proposes an extension to die OSI ŽOpen Systems Interconnection . Reference Model by using three different models that are specified in an integrated way. The extended model incorporates the ’de facto’ standards used for Internet network management. A basic knowledge of the Internet and OSI-based network management systems is assumed. 8 Refs.
