Implementing Simple Modular ERDF ontologies Carlos Viegas Damasio1 and Anastasia Analyti2 and Grigoris Antoniou3

Summary: Implementing Simple Modular ERDF ontologies
Carlos Viegas Dam´asio1 and Anastasia Analyti2 and Grigoris Antoniou3
Abstract. The Extended Resource Description Framework has
been proposed to equip RDF graphs with weak and strong negation,
as well as derivation rules, increasing the expressiveness of ordinary
RDF graphs. In parallel, the Modular Web framework enables collab-
orative and controlled reasoning in the Semantic Web. In this paper
we show how to use the Modular Web Framework to capture the
modular semantics for ERDF graphs, supporting local semantics and
different points of view, local closed-world and open-world assump-
tions, and scoped negation-as-failure.
1 Introduction
The Extended Resource Description framework [1] (ERDF) provides
a model theoretical semantics for RDF graphs allowing negative
triples, and ontologies defined by first-order rules including the two
forms of negation, weak and strong. Subsequently, the ERDF frame-
work has been extended to allow the specification of import and ex-
port declarations of classes and properties, resulting in the Modular
ERDF framework [3]. The Modular Web Framework (MWeb) is a
proposal to address the issues of programming-in-the-wide faced by
