A synthesis approach for deriving reference models for SOA frameworks

Improving business processes and services is a challenge that can be met by a model-driven approach to service design and development. This approach rests on defining reference models of the enterprise business processes that will become the drivers of service frameworks. As part of a national program for developing such models within a Service Oriented Architecture (SOA) framework for e-learning and research in higher education, a canonical reference model for course validation was used to demonstrate the feasibility of the approach. Course validation processes in four UK Higher Education Institutions (HEIs) were analysed and modelled using interviews and process documentation. Each institution’s process was modelled with UML Activity Diagrams and its domain information with Class Diagrams. The four models were synthesized into a single canonical reference model of the validation process. This required resolving process model structures and element granularity. Synthesis of the canonical model demonstrated a methodological basis for developing service specifications, within a SOA framework that could serve all institutions in the sector.
