Toward a Canonical Method to Solve Patterns of Ontology Modelling Issues 16 ____________________________________________________________________________________________________________the hollow boxes indicate just “necessary” conditions for instances of those classes. Figure 5(a) and 5(b) respectively, shows the graphical representation of these conditions in the Protégé ontology editor. An overview of these two ontological concepts can be found in (Horridge et al. 2004). In conclusion, the technique described of using OWL Datatype property values as “tags”, avoids imposing a fault classification overly complicated and specialized onto the ontology application, shifting the focus from having to decide where in the highly coupled taxonomy a fault instance should be classified, into selecting the suitable property values for that instance instead. In general terms this could be seen as an attempt to create an ontology that is more agnostic of a pre-established taxonomy and more oriented to a user-developed classification (“folksonomy”) without compromising the semantic expressivity of the target data, given that all fault categories can still be represented by virtue of selecting the applicable property values. Although strictly speaking, the approach conforms more to a facet classification scheme (Pietro-Diaz, 2003) given that the property values conforms to a closed vocabulary of selected terms rather than being entirely user-defined as it is actually the case in a “folksonomy”. 3.1.4. An Ontology for ReSIST University Curricula Another objective of the ReSIST project, to be carried out by its Training and Dissemination working group, is to promote and propagate a resilience culture in university curricula and in engineering best practices (ReSIST, 2006). To support this objective the ReSIST Knowledge Base would devote a section of its application to the management of information regarding university courses in the subject of resilience. This section describes much of the work completed regarding the development of different aspects of this application that is relevant to this report. The initial source of requirements for the ReSIST University Curricula knowledge base application was a draft template document describing the information to capture about a university course produced by the Training and Dissemination committee in ReSIST. To make this template part of the overall ReSIST knowledge base, it was necessary to expand the main ontology with the glossary terms and properties captured in the template. Once again, as described in section 3.1.2., before attempting to build this new “ReSIST Course” ontology from scratch, a quick survey was conducted to re-use an existing one that could deem suitable. None of the ontologies found, implemented as OWL files, seemed fit for purpose because despite containing some references to the terms searched (course, syllabus, curriculum,
