MUSICES – MUSical Instrument Computed tomography Examination Standard

© Fraunhofer EZRT,Druck

The Fraunhofer Development Center for X-ray Technology EZRT, the Germanisches Nationalmuseum (GNM) and the Chair of X-ray Microscopy (LRM) at Julius-Maximilians-Universität in Würzburg have joined forces: since November 2014, the institutions have been collaborating on the MUSICES project, funded for three years by the German Research Foundation (DFG) with the objective of developing guidelines and procedural instructions for the three-dimensional computed tomography of musical instruments. The goal is to create worldwide standards that ensure comparable image quality.

Tasks for Fraunhofer EZRT and project partners

The project goals were as follows:

  • Produce a device-independent description of technical variables for the 3D CT imaging of different materials, object sizes and material combinations for musical instruments.
  • A description of open formats for derivatives for presentation on the Internet and the disclosure in the sense of open access.
  • Produce a description of open formats for derivatives for presentation online and circulation in the spirit of open access.
  • Define minimum resolutions for 3D computed tomographies for different types of musical instruments, depending on size, material and possible areas of application: research and teaching, museum education, restoration, reconstruction, creation of replicas, etc.
  • Specify fine details to be included in the scans for various instrument types, in particular for larger objects where a full high-resolution scan is not feasible or practical.
  • Formulate the requisite metadata for 3D computed tomographies in compliance with the LIDO/MIMO-LIDO model and with ISO standard CIDOC-CRM (ISO 21127:2006).
  • Integrate the metadata and the generated 3D computed tomographies into the MIMO international certification system for musical instruments in public collections. Transfer information to EUROPEANA via harvesting.
  • Compose the standard document to supplement DFG’s practical “Digitalization” rules and the MIMO digitization standard.
  • Formulate best-practice recommendations based on the MIMO digitization standard.

Program and funding

  • Funded by the German Research Foundation (DFG)
  • Project duration: November 1, 2014–October 31, 2017
