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)

高分辨率的三维工业计算机断层扫描（3D-CT）是检查和记录收藏品中的乐器的首选手段，因为传统的调查技术能够访问和测量某些重要的结构细节，这些细节不够充分，或者以一种危险的方式，或者根本没有。然而，在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，需要在测试运行的时间和成本上经常付出相当大的努力。使用不同类型和尺寸的代表性乐器语料库，该标准将提供指导方针，使乐器的高质量三维断层扫描独立于特定的ct设备，操作员或查看软件。3D-CT允许任何部分或视图，包括物体的内部，例如根据它们的密度分离材料。此外，该项目涉及各国际科学界，以决定哪种类型的仪器对哪些细节特别感兴趣，因此应以更高的分辨率描绘。将开发3d - ct元数据模型并将其集成到lido标准中。这些结果将通过国际数据库MIMO-DB和Europeana以及合作机构的网站进行访问，这些网站将通过德国数字图书馆（Deutsche Digital Bibliothek）进行访问，以便将来收集。基于项目经验的最佳实践指南将记录典型的工作流程，并将作为支持，使未来的3D-CT数字化项目更高效。鉴于乐器的构造复杂性，该标准有望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.
