The "Guidelines for the Use of Digital Techniques in Conservation-Restoration and in the Presentation of Fragments" are in progress.

Topic
Works of art are mostly handed down in fragments. The handling of the fragment, its investigation, preservation and mediation are among the central tasks of conservator-restorers operating in the preservation of cultural monuments, in museums and libraries. The treatment of the fragment has always depended on the respective social context and the taste of contemporary times - this is still true today: between the two poles of complete restoration on one side and the preservation of the fragmentary state on the other, there are the most diverse possibilities of real or virtual reintegration, based on different theoretical principles. The new media offer us even more efficient methods and techniques of virtual supplementation and the mediation of fragmentary works, and these have found great social acceptance. They have undoubtedly changed the way we look at cultural heritage. How can we use them for their best possible preservation and presentation?

The major conferences in Germany on the subject of the digital in restoration and monument conservation until our call for papers in Summer 2019 (including "Das Digitale und die Denkmalpflege", 2016, published 2017; "museum-3-d-digital", February 2018; "3D - Durchblick oder Datenmüll? Dreidimensionale Scanverfahren in der Konservierung/Restaurierung", March 2018; "das-digitale-objekt", December 2018), devoted themselves not only to the various areas of application of digital technology, but also to the sustainable management and linking of the data generated.
This conference has put the focus on what the new digital possibilities mean for the preservation and mediation of the historical fragment. Experts from various disciplines currently perceive "a gap between the increasing importance and professionalization of the visual reconstruction of the historical on the one hand and the theoretical foundation of such activities on the other" (Hoppe/Breitling 2016).

Do today's possibilities lead to more or fewer interventions of restoration? The step towards reconstruction or partial reconstruction becomes simpler, but the demand for differentiation between the original and the time-bound suggestions of the supplement becomes stronger. Often the digital representation seems to draw all the attention to itself and the original fragment is pushed into the background. But also the opposite tendency, the desire for more materiality, is increasingly gaining relevance.
How can digital technology increase the acceptance of the fragmentary original? The new possibilities certainly help in the visualization of research results and in the communication between experts and society and also offer great opportunities for the sustainable preservation of our cultural heritage.

The speakers
Experts from eight countries from various disciplines, such as conservation/restoration, art history, architecture, archaeology, computer science and the psychology of perception, provided answers. The case studies outlined almost 2000 years of cultural history and come from very different contexts and art genres. They were fragments of architecture, large sculptures, paintings, murals, plaster relief, marble sculpture, and ceramics.

The objective
The aim of the critical debates at the conference has been to produce a charta on how to deal with the fragment in the conservation-restoration sciences. The established ethical and theoretical principles of conservation-restoration must take into account the new digital possibilities with additional considerations of principles. Scientific standards should also apply to the digital world, i.e the objective and speculative parts of virtual reconstructions must be clearly identifiable for viewers, and their psychological effects on perception must be recognised.

Conference languages
The conference languages were German and English. Simultaneous translation was not possible.
