Abstract:In the field of asset management, data modelling is used to design data structures which allow to digitally represent the desired real-world objects, concepts, and the relations between them. This, in turn, supports more structured and analytic decision making in asset management. The Operation & Maintenance Domain Ontology (O&M-model) is such a conceptual data model, and it was originally developed by Ter Huurne (2019). It allows representing utility networks from the perspective of their operation & maintenance, integrating concepts from their whole lifecycle. The O&M-model is a revised version of the Utility Network Application Domain Extension (ADE) of CityGML, an extension of the model for representing utilities. CityGML is, in turn, a digital model to represent cities, including a variety of above-ground city objects, their appearance, geometry, topology, and semantic information (e.g. the number of occupants, age, etc.). The O&M-model can be used for two main purposes:  To derive a so-called data transfer format schema, to allow exchanging O&M information between a source and a target system (e.g. a utility owner and a contractor).  To derive a database schema, that can be used to set up a spatial database. Spatial databases are the most common solution for storage, manipulation, analysis, and presentation of asset data for organizations dealing with assets occupying a large surface (such as utility networks and cities). The derivation of the database schema of the O&M-model is the focus of this study. My goal was to create a prototype database that could be used by the department of Campus & Facility Management (C&FM) of the University of Twente to manage their utility networks. To design it I followed the iterative design cycle proposed by Wieringa (2010). It begins with the problem investigation phase during which I explore the stakeholders’ challenges, goals, and the phenomena that define the problem. This phase is followed by a design phase during which I design an artefact to treat the problems and ends with a validation phase to check whether the design meets the stakeholder’s requirements.
