RDF is a data model whose relevance is growing in the last years. Recently, some proposals have enriched the model with integrity constraints, well known within relational databases. In this work we extend an existing framework with two new types of integrity constraints of disjunctive nature, inspired by similar kinds of dependencies studied for the relational model. The problem of the logical implication for the two novel categories is also analyzed. Moreover, as an application scenario, we propose a complete and independent set of constraints to model the context in RDF, where the context is a notion employed in databases to perform information filtering on the basis of the user's current situation.

Abstract

RDF is a data model whose relevance is growing in the last years. Recently, some proposals have enriched the model with integrity constraints, well known within relational databases. In this work we extend an existing framework with two new types of integrity constraints of disjunctive nature, inspired by similar kinds of dependencies studied for the relational model. The problem of the logical implication for the two novel categories is also analyzed. Moreover, as an application scenario, we propose a complete and independent set of constraints to model the context in RDF, where the context is a notion employed in databases to perform information filtering on the basis of the user's current situation.
