The members of the Working Group “Digitale Rekonstruktion” invite colleagues to join the Round Table DATA MODEL BEYOND THE DIGITAL 3D MODEL

at the CHNT Conference, November 8-10, 2017 in Vienna.

Scheduled for Friday, November 10th, 2017, 2:00 – 3:40 pm

DATA MODEL BEYOND THE DIGITAL 3D MODEL
Towards a harmonised digital 3D research data

The digital hypothetical 3D reconstructions, known as Virtual Reconstructions since the beginning of the 1990s, are already an established visualisation and dissemination method in archeology, art and architecture history. Besides the impressive visualisation results of the digital models and virtual scenes, the knowledge beyond the textured geometry is still not accessible after the project is finished. Locked in the mind of the project participants, the analogue/paper folders at or in best case in the repositories of the research institutions there is no available added value. The interoperability, sustainability and accessibility of the research results are limited to the publication in a print medium or in a film animation.

In regard to the immense interpretative research work and the knowledge fusion during a digital hypothetical 3D reconstruction as well as the high cost of the projects this situation is unsatisfying. In the last five years we recognise an emerging interest in the Semantic Web Technologies and the harmonisation of the digital research data – the main raw material of the information society. There are several research projects and research papers on documentation and an adequate data model for the 3D visualisation and the 3D data sets of the hypothetical 3D reconstruction. But still there is no common approach and a lack of knowledge exchange in this specific research field.

The round table invites players from the 3D community to discuss the documentation approach and the design of the data model for digital 3D reconstructions. The participants will deal with the crucial role of the authority files, controlled vocabularies and customised thesaurus-editors (labelling systems) as well as the leading reference ontology CIDOC CRM and the Linked Data requirements in general.

In addition the 3D data format and the web-based processing of the interactive visualisation will be of interest too. Here the visualisation and documentation of the hypothetical value within the versions and variants of a reconstruction will be discussed.

The goal of the round table is to clarify the positions and to agree to a documentation standard on the basis of a core data model as a common denominator, or at least to make a step in the direction of human and machine readable interoperable 3D models and visualisations.
