Abstract

This paper proposes a new method to handle policies in Resource Management of Workflow Systems. Three types of policies are studied including qualification, requirement and substitution policies. The first two types of policies map an activity specification into constraints on resources that are qualified to carry out the activity. The third type of policies intends to suggest alternatives in cases where requested resources are not available. An SQL-like language is used to specify policies. Policy enforcement is realized through a query rewriting based on relevant policies. A novel approach is investigated for effective management of large policy bases, which consists of relational representation of policies and efficient retrieval of relevant policies for a given resource query.
