Generating Semantic Web Services from Declarative Descriptions.

Semantic Web services are an effective middleware for semantic querying of relational databases. Despite the benefits of this approach, writing Web service code manually is labor-intensive and error-prone. To ameliorate this, we propose a framework to generate SADI web services from declarative service descriptions in which access to databases is achieved through semantic mappings. These mappings are scripted in the Datalog sublanguage of Positional-Slotted ObjectApplicative (PSOA) RuleML. We outline a novel methodology, a system architecture, and an early stage implementation for service generation. We demonstrate the utility of this approach in a use case for querying patient data from a hospital data warehouse.
