Digitisation / Cataloguing of non-textual objects: Creation of a Standard for the 3D computed tomography of musical instruments and enhancement of the MIMO Digitisation Standard (DFG-MUSICES)

高分辨率三维工业计算机断层扫描（3D-CT）是检查和记录收藏中的乐器的首选手段，因为传统的调查技术无法充分或以危险的方式或根本无法访问和测量某些重要的结构细节。然而，仪器结构中使用的大量材料及其组合以及非常不同的物体尺寸对这种方法来说是一个持续的挑战，经常需要大量的时间和成本来进行测试。使用不同类型和尺寸的乐器的代表性语料库，该标准将提供能够独立于特定CT设施、操作员或查看软件对乐器进行高质量三维断层扫描的指南。3D-CT允许任何截面或视图，包括物体的内部，例如根据其密度分离材料。此外，该项目还请各国际科学界决定哪些细节对哪类仪器特别重要，因此应以更高的分辨率加以描述。3D-CT的元数据模型将被开发并整合到LIDO标准中。研究结果将通过国际数据库MIMO-DB和Europeana以及伙伴机构的网站提供，这些网站将通过德国数字图书馆（Deutsche Digitale Bibliothek）提供，供今后收集。最佳实践指南，根据项目获得的经验，将记录典型的工作流程，并应作为支持，使未来的3D-CT数字化项目更有效。考虑到乐器的结构复杂性，预计该标准将在合理的修改范围内转移到其他对象组。

High-resolution, three-dimensional industrial computed tomography (3D-CT) is a preferred means for examining and documenting musical instruments in collections, as conventional investigation techniques are able to access and measure certain important constructional details not sufficiently, or in a risky way, or not at all. The multitude of materials and their combinations as used in instrument construction as well as the very differing object sizes are, however, a constant challenge for this method, requesting frequently considerable efforts in time and costs for test runs. Using a representative corpus of instruments of different types and sizes, the standard will provide guidelines enabling high-quality three-dimensional tomographies of a musical instrument, independently of a particular CT-facility, operator, or viewing software. The 3D-CT allows any section or views including the interior of the object and e.g. the separation of materials according to their densities. Further on, the project involves the respective international scientific community to decide which details are of particular interest for which type of instrument and should therefore be depicted in higher resolution. A metadata model for 3D-CTs will be developed and integrated into the LIDO-standard. The results will be made accessible via the international database MIMO-DB and Europeana as well through the websites of the partner institutions where they will be accessible for future harvesting through the German Digital Library (Deutsche Digitale Bibliothek). A best-practice-guide, based on the experience acquired with the project will document paradigmatic workflows and shall act as support for making future 3D-CT digitization projects more efficient. Given the constructive complexity of musical instruments the standard is expected to be transferred to other groups of objects within a reasonable scale of modifications.
