A Parthood Approach for Modeling Tangible Objects’ Composition TOC - An Application on Cultural Heritage
Résumé
Several semantic web approaches tackle the problem of integrating multidisciplinary rich content using Linked Open Data. Cultural heritage (CH) is a multidisciplinary domain that contains a massive heterogeneous content that varies distinctly by types and properties. Various semantic web approaches have been proposed in the context of CH, and at multiple integration levels (local, national, international). These approaches focus on metadata schemata integration but give no significant importance to the representation of a tangible cultural heritage object, as a whole entity, and the different parts that compose it. Targeting the goal of the preservation and restoration of CH artifacts, we aim at modeling the CH content focusing on the composition of a CH object. We thus illustrate here an approach of using a part-whole and spatial relations to model the composition of a tangible object in general, and a CH object in particular. To do this, we introduce parthood concepts and properties for representing the composition mechanism, and 7 cases of parthood/spatial relations in tangible objects, with their corresponding logical/ontological relation(s). We implement our approach using OWL2 as the ontological language for our linked open data approach.
