Model-driven and pattern-based integration of process-driven SOA models

Service-oriented architectures (SOA) are increasingly us ed in the context of business processes. However, the modeling approaches for process-driven SOAs do not yet suffi ciently integrate the various kinds of models relevant for a process-driven SOA ‐ ranging from process models to sof tware architectural models to software design models. We propose to integrate process-driven SOA models via a mode l-driven software development approach that is based on proven practices documented as software patterns. We int roduce pattern primitives as an intermediate abstraction to formally model the participants in the solutions that pat terns convey. To enable model-driven development, we develop domain-specific modeling languages for each kind ofprocess-driven SOA model ‐ based on formal metamodels that are extended with the pattern primitives. The va rious process-driven SOA models are integrated in a model-driven tool chain via the meta-models. Our tool chainvalidates the process-driven SOA models with regard to the constraints given by the meta-models and primitives.
