Abstract:
Digital 3D reconstructed models of Cultural Heritage (CH) assets have to be understood as a combination of research sources, the contemporary historical and cultural context (Zeitgeist), the project background and the work process. All available information is collected, consolidated, filtered and assembled into a coherent picture. In the case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. This paper gives a structured view on digital 3D reconstructed models within the CH domain. They are understood as a result of a complex creative process and as a synthesis of a CH research project, its CH context, the available research source material, and the modeling process itself. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases of such projects allowing a quality assessment. Semantic technologies are used to consolidate the structured view. Relevant components are represented through classes and inter-dependencies in an ontology model (so-called COSCHKR ontology model). Furthermore, the inter-dependencies are bound by rules. Through a guided user interface, these rules are inferred in order to retrieve information based on individual user input supporting the planning of projects creating digital 3D reconstructed models.

Relevance conference | Relevance session:
An interdisciplinary approach is presented using semantic technologies to support CH projects creating digital 3D reconstructed models.

Innovation:
A guide is developed giving access to semantically structured expert’s knowledge involved in the creation of 3D reconstructed models.
