A Systemic, Ontology-driven Approach to e-Services Governance

This paper proposes an ontology driven, systemic approach to eservices governance. E-service governance refers to frameworks and policies for controlling the development and provision of e-services within an organisation. Given the level of complexity of current e-services, it is necessary to think of them as systems of interconnected elements that are more complex than the sum of their parts. Our IDEF0 based, system theory inspired, modelling approach, captures the essence of governing systems of e-services contained (recursively) within higher order systems. We use ontologies to represent explicitly systemic properties of services such as context, control/constraints and feedback. Governance rules constrain the syntactical, semantic, and behavioural properties of service ontologies and, due to the hierarchical ordering of service systems, can be applied to e-service portfolio management, architectural design compliance, and runtime SLA enforcement. Ontology mapping capabilities allow governance rules to be described using concepts appropriate for the different levels of service.
