The digital reconstruction of important buildings and structures, which are frequently used in the scientific practice to study historical contexts and constructions, are part of the digital cultural heritage. The translation into digital models is based on the evaluation and collection of all sources in years of processing. This is characterized by a permanent consolidation of the knowledge and the implementation of the data into 3d-models. At the subject group „Information and Communication Technology in Architecture“ at Technische Universität Darmstadt an international and interdisciplinary project was digitally reconstructed: The Tombs of the Emperor of Xian, Shaanxi Province, China. Some partially unpublished research by German and Chinese scientists were taken as a basis. This project and the Charter of UNESCO gave the inducem...

All available information is collected, consolidated, filtered and assembled into a coherent picture. In case of digital 3D reconstructed models, the result is a digital data set that can be processed for different application fields. 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. For all visualisation types in CH different conditions, factors, and basic rules apply to achieve a high quality result. Two examples are presented illustrating the structured view on visualisation projects as such. This paper seeks to differentiate the various research sources being the basis for digital 3D reconstructed models and defines work phases allowing a quality assessment. Furthermore, the potentials of including this structured view into the ontology COSCHKR currently under development is discussed. In combindation with traditional guidelines COSCHKR platform could open up new and flexible approaches.

The main potential of such reconstructions give an opportunity to present the research in different ways.

The lecture will give an overview on teaching and research of this topic. In numerous seminars different topics of this subject area were investigated. One of the main topics was on research projects in the field of history of architecture. These research projects were integrated into science studios which are part of teaching. Science studios are a special kind of teaching and were established in this subject group. The definition of science studios is an interdisciplinary discussion determined by different perception of the respective research project in the areas of art, technology and society. Digital reconstructions were the tombs of the Emperor of Xi'an as well as the visualization of the vision of Atlantropa. This concept of teaching and researching was completed by workshops and seminars which looked into current topics in the field of architecture and digital media. Part of it was the discussion of the virtual world "Second Life" as place of teaching of architecture and the draft of new concepts of teaching which will be used there. Furthermore the façade design with the new building material "information".

Digital reconstruction is a digitally based reproduction of a no longer visible or no longer existent building, urban complex, structural environment or events influencing structural environment. It is based on scientific findings and other sources of human knowledge. According to this and the UNESCO Charta, digital reconstructions are regarded as part of digital cultural heritage. Based on a basic theoretical study of the science of documentation, the digital reconstruction and investigation of past reconstruction projects an appropriate system of documentation was developed. It is called Four-Level-System and it includes all necessary levels of a digital reconstruction project and leads to a complete, transparent and editable documentation. The Four-Level-System as a common documentation system for digital reconstructions was transferred into a reference project the digital reconstruction of the Mausoleum of the Tang-Dynastie at Zhaoling, China, a subproject of the main project "The Digital Reconstruction of the Imperial Tombs of Xi'an", realized at the The result is a first detailed documentation of a digital reconstruction. All sources, references, background informations and the project process are shown by this documentation. This new developed methodology of documentation makes the knowledge of a digital reconstruction available for subsequent generations of researchers.The results of a digital reconstruction can thus be reviewed at any time and the current state of knowledge to be adapted. Documentation system for digital reconstructions The UNESCO Charta The Charta "For the Preservation of Digital Cultural Heritage" issued by UNESCO in 2003 was the starting point for the researches about a documentation system for digital reconstruction as a contribution to the preservation of knowledge within our digital cultural heritage. The UNESCO Charta defined digital cultural heritage as follows: Digital heritage consists of unique sources of human knowledge and human means of expression. It encompasses sources from all areas of daily life that are available in digital form (UNESCO 2003).
