Abstract: The trend towards ubiquitous public services is driving the deployment of large-scale, heterogeneous, distributed information services. In order to support automated information access and processing, this information is marked up using semantic metadata models represented using ontology languages such as OWL. The use of such a semantic metadata model is twofold: to enable content-based access and to provide services that enable users and applications to select, employ, compose and monitor web-based resources automatically. Deployment of a semantic model consists of the semantic metadata model itself and the semantic services to leverage the semantic metadata within application services. The main objective of this paper is to show how an existing semantic-based security management of open services framework has been extended to improve the safety of services using a semantic error management model. It has been applied to an application that queries multiple distributed environmental database resources.
Keywords: safety management; open services; semantic services; security management; Web Ontology Language; OWL; middleware; web services; error management; modelling; distributed information services.
