Dynamic Business Collaborations Through Contract Services

Abstract

New applications have recently emerged within the domains of e-Health, e-Science, e-Research and e-Government that require the formation of dynamic collaborations between independent, autonomous business organizations for the duration of a project designed with a specific purpose. To successfully create and manage such collaborations, there is a need of a standard way to specify: (a) what resources are required, (b) who will contribute resources, (c) the type of access required to these resources, (d) agreement and obligations of the partners within the business collaboration, with the terms and conditions specified in the agreement, and (e) how to instantiate, maintain and terminate such business collaborations easily and in a well understood manner. The authors address these issues through the creation, negotiation and execution of an agreed electronic contract. First, this paper provides a framework for an electronic contract (e-Contract) by introducing a Web Service Collaborative Context Definition Language (WS-CCDL), which was developed in the context of dynamic business collaboration. Then, the authors illustrate its use with a universal (anywhere) connectivity service for a tele-Collaboration application in the context of e-Research domain. Both architectural design and implementation considerations are provided to highlight the feasibility and complicity of the technologies.
