DEVELOPMENT OF THE METHODOLOGY AND INFRASTRUCTURE FOR DIGITAL 3D RECONSTRUCTION

The discussion about the digital source-based 3D reconstruction in recent years concerns scientific validation of the 3D models in the terms of scientific documentation and publication of the digital research data. Currently, published guidelines and principles cover only general approaches and do not reveal the answer to questions about how to give scientific meaning to the digital reconstruction of destroyed or never realized build cultural heritage. Against this background, the scientific methodology for digital reconstruction was proposed. The experience gained in accomplished reconstruction projects at the Hochschule Mainz reveal how to capture the process with special emphasis on scientific aspects like semantic division of the architecture, used historical sources or documentation templates. The development of the methodology was supported by researchers from the University of Bologna, who are concerned with the issue of uncertainty and how to implement the degree of hypothesis to the 3D visualization. The proposed methodology includes the documentation of the 3d model, in particular the metadata scheme as the core information carrier about the 3d data sets. The scheme was developed on the basis of analysis of metadata contained in the most popular repositories of 3D models from the commercial and institutional offer. The schema was transformed into a semantic data model OntSciDoc3D based on the CIDOC Conceptual Reference Model ontology (ISO 21127:2014), enabling the understanding of the data contained in the 3d repository also for machines. The documentation also considers the possibility of automatization of the documentation process. Providing the identifiers from external databases will enable displaying data related to identifiers which will cause the repository to be considered as Linked (Open) Data. The methodology will be presented aganist the background of the 3d repository DFG 3D-Viewer (currently under development) corresponding the Good Research Practice provided by the Deutsche Forschungsgemeinschaft (DFG, German Research Council). The features under development are conform to the proposed methodology and are promising according innovative infrastructure for the documentation and publication of scientific 3D reconstruction.
