Efficient brokerage in a CORBA-based service mediation platform

The rapid development of electronic commerce applications and information services has led to a significant need for mediation services. The brokerage of services is one particular mediation service. In this article, we present the design of service brokerage for a CORBA-based mediation platform that symmetrically supports advertising by service providers and navigation by end-users. A particular strength of this design is in the support by dynamic profile and profile rule management for both end-users and service providers. In advertising and navigation, service offer information is dynamically filtered and matched according to the profiles of end-users and service providers, such that an optical focus of information dissemination is achieved. This is a cornerstone for dynamic provisioning of services in order to support the evolution of the marketplace. The presented design is partially based on TINA and OMG specifications.
