Modelling of the ODP Trader for use in Resource Discovery

摘要

As information technology expands from the workplace to the home, a huge variety of new vendors and services will become available to consumers. These services will fall into three main categories: information services, shopping and entertainmentrnOne of the major problems facing an increasingly information-rich society is how to quickly and conveniently locate information which is provided by different servers throughout a large distributed system. The Reference Model for Open Distributed Processing (RM-ODP) deals with the problem of locating services/resources in a heterogeneous Open Distributed System through the standardisation of a Trading function which is realised by a Trader.rnAlthough initially intended for dynamic binding of computational resources in a distributed system, it is apparent that the Trading function has applications in Community Networking for service/resource location. The authors are interested in validating the Trader standard using Coloured Petri Nets (CPNs) and investigating Trader's applicability in the provision of advanced information services.
