Current workflow languages introduce limitations regardingmodularity and flexibility. They are lacking support forreusability of primitive and structured activities. Designing processes often leads to duplication which makes the workflow descriptor complicated and unnecessarily large. Furthermore, due to the static character of the scripts, there is insufficient flexibility to model dynamic, evolvable and failsafe workflows. In this paper we present a framework that allows the design of WS-BPEL processes in a modular way based on reusable templates. In addition, we introduce an extra layer on top of WS-BPEL that allows template processing based on parameter values. This layer offers support for decision logic to adapt processes dynamically. The approach is based on the ”Ruby On Rails” (RoR) framework, known for adding dynamism to static web pages. The proposed solution is portable with existing WS-BPEL engines.status: publishe
