Web services are becoming the prominent paradigm for distributed computing and electronic business. This has raised the opportunity for service providers and application developers to develop value-added services by combining existing web services. However, current web service composition solutions do not address software engineering principles for raising the level of abstraction in web-services by providing facilities for packaging, re-using, specializing and customizing service compositions.

Abstract. Current composite web service development and management solutions, e.g. BPEL, do not cater for flexible and adaptive business collaborations due to their pre-defined and inflexible nature that precludes them accommodating business dynamics. In this paper we propose a rule driven approach for adaptive business collaboration development in which rules drive and govern the development process. We introduce the Business Collaboration Development Framework (BCDF), which provides enterprizes with the context to define their capabilities and business collaboration agreements. Subsequently, we explain how rules can drive and control the business collaboration development process to develop complete, correct and consistent business collaboration agreements that are conform the conditions under which parties wish to cooperate. 1

Current composite web service development and management solutions, e.g. BPEL, do not cater for flexible and adaptive business collaborations due to their predefined and inflexible nature that precludes them accommodating business dynamics. In this report we present the second component of our rule driven approach for business collaboration development and management. The approach provides a model driven approach to capture the context in which business collaboration takes place; where the benefit is that enterprizes are enabled to describe their cooperations with others in the form of models. This allows enterprizes to make their own position, collaboration potential and agreements explicit in an unambiguous and well-defined manner. The resulting models can subsequently be utilized for communication and reference purposes, as well as constitute the basis for the actual execution of collaborations.

Current composite web service development and management solutions, e.g. BPEL, do not cater for flexible and adaptive business collaborations due to their predefined and inflexible nature that precludes them accommodating business dynamics. In this report we propose a rule driven approach for adaptive business collaboration development in which rules drive and govern the development process. We briefly introduce the Business Collaboration Context Framework (BCCF), which provides enterprizes with the context required for business collaboration. Then, we shortly explain our model driven approach that based on the BCCF provides enterprizes with the means to capture their different collaboration behaviors both from a business and technical point of view. Subsequently, we set out how we utilize rules to drive the development and management of business collaboration models to make them more flexible and adaptive.
