In this paper the authors introduce hierarchical service models suitable for large service parks. They describe a method for handling higher-order workflows that is used for automatic composition of services. A description is given of a specification language suitable for representing hierarchical service models. The authors introduce two kinds of ontologies: service ontologies and unser ontologies, and demonstrate their usage in experiments on Estonian e-government information system.
