Interpretations between RDF and the logical data model

Abstract

In 1984 Kuper and Vardi presented a logical data model (LDM) which generalizes the relational, hierarchical and networks database models. In this model, a database is a schema represented by a directed multigraph whose leaves represent data. In 1998, the W3C proposed the resource description framework (RDF) as a data model for representing the network of metadata on the Web. In this short paper we show that LDM and RDF are mutually interpretable in each other, presenting the result for RDF without vocabulary from RDFS.
