(will be inserted by the editor) Style-Based Modeling and Refinement of Service-Oriented Architectures?

Abstract Service-oriented architectures (SOA) pro-vide a flexible and dynamic platform for implementing business solutions. In this paper, we address the mod-eling of such architectures by refining business-oriented architectures, which abstract from technology aspects, into service-oriented ones, focusing on the ability of dy-namic reconfiguration (binding to new services at run-time) typical for SOA. The refinement is based on conceptual models of the platforms involved as architectural styles, formalized by graph transformation systems. Based on a refinement relation between abstract and platform-specific styles we investigate how to realize business-specific scenarios on the SOA platform by automatically deriving refined, SOA-specific reconfiguration scenarios.
