ABSTRACT
Knowledge-based representations provide information in a form that can be used by computer systems. This paper reports the process of finding existing knowledge-based representations for the Built Cultural Heritage (BCH) domain. Strengths and weaknesses of the knowledge-based representations for supporting the development of a system for preventive conservation of BCH are explored. In the BCH-field, multiple actors from various disciplines use a variety of data sources and data models, resulting in a complex data integration problem. In our research, the focus is on explicitly representing 3D features by using the City Geography Markup Language (CityGML) standard. However, CityGML lacks the semantic refinement required for the representation of thematic concepts of the BCH-domain, e.g. vulnerability or legal protection issues; or BCH-components such as pilasters, cornices, etc. To address these shortcomings we present an ontological approach rooted in two pre-existing ontologies: the Geneva-CityGML ontology (an ontological approach based on CityGML), and MONDIS (the monument damage ontology).
