Representing RDF and RDF Schema in the HDM

The AutoMed project uses a nested hypergraph common data model (the HDM) to integrate heterogeneous datasources. Previous work has shown how data models including the relational, ER and XML models, can be mapped on to HDM to facilitate schema integration. RDF is a general-purpose language for representing information on the World Wide Web. It provides a data model for describing properties of resources in the web and their interrelationships. RDF Schema provides a basic type system for RDF models which is implemented in terms of classes and properties. These technologies are increasingly used in the semantic web effort in particular for defining ontologies. This technical report shows how RDF and RDF Schema can be modeled in the HDM thereby allowing data in these formats to be treated as an AutoMed datasource.
