In Service Oriented systems organisational processes are represented as WS-BPEL workflows, WS-BPEL is different from traditional workflow languages as a hybrid of block-based and graph-based language; it also has limited support for separation of concerns. Changes to such processes usually impact many places in the underlying system, without separating such cross-cutting concerns system maintenance is therefore difficult. This work proposed an Aspect Oriented solution to maintaining WS-BPEL workflows using meta-model transformation.
