Abstract :
The specification of clinical items is a fundamental problem in the planning of a clinical trial. In this paper we present an approach that uses an RDF model in combination with a suite of OWL ontologies to formally describe the structural and conceptual composition of items. We argue that a semantic Web data model is more flexible than traditional relational models and therefore more appropriate for specifying and managing data variables with regard to data validity and mappings to external medical terminologies.
