préparation pendant la campagne de numérisation


Since 2009


Musical instruments are witnesses of thousands years of human creativity and innovation. Their diversity is enormous. European museums preserve an important part of this material heritage, housing hundreds of thousands of instruments from all over the world. They preserve and exhibit them, and spread knowledge about them to provide insights, to inspire and to connect. Good collections of musical instruments teach us about musical traditions and (changing)cultural identities..

In Spring 2008, collaborators of several major European museums with musical instrument collections came together to make this musical heritage known worldwide as a whole, in a coherent way. They launched a project to digitize their collections and publish them online in a multilingual environment. A two-year funding was obtained from the European Commission (eContentPlus program). The purpose of the project was to provide a common access route for those who wanted to explore this heritage online and to create cohesion. Common standards were realised for instrument names and makers, and for their visual representation (in which position and from what point of view do pictures of different types of instruments give the most information?).

The project was approved in the Spring of 2009. MIMO was born. The kick-off meeting took place in Florence, in September 2009. The participating partners from the very beginning were:

  • University of Edinburgh, United Kingdom (initiator and project management)

  • Africamuseum, Tervuren, Belgium

  • Cité de la Musique / Philharmonie, Paris, France

  • Galleria dell'Academia, Florence, Italy

  • Germanisches Nationalmuseum, Nuremberg, Germany

  • Horniman Museum, London, United Kingdom

  • Musical Instruments Museum, Brussels, Belgium

  • Stiftung Preussischer Kulturbesitz, Ethnologisches Museum, Berlin, Germany

  • Scenkonstmuseet, Swedish Museum of Performing Arts, Stockholm, Sweden

  • University of Leipzig, Museum für Musikinstrumente, Germany

During the next two years, the partners brought together metadata from more than 45.000 instruments in the MIMO portal. The digital content of local collection databases was collected into a MIMO ‘reservoir’ via an Open Archives Initiative (OAI) protocol. The museums took pictures of their collections according to the new MIMO photo standard. They linked all instruments to the new multilingual thesaurus with about 2250 object names, to a new thesaurus of makers, and to the international Sachs-Hornbostel classification system, which the MIMO group had completely revised for the occasion and supplemented with a classification of electrical and electronic instruments. 1250 digital audio files were also inserted into the database. The fact that this number is small compared to the number of pictures is partly because of the limited number of historical instruments that are still playable. This makes the listening examples extra valuable. Even rarer and more valuable are video recordings of historical performances. Currently 300 video clips are available online.

At the end of 2011, the digitized musical heritage of the museums involved was fully accessible to the specialized user (curators, researchers, students) through the search interface and to the general public through Europeana, the European digital library. The available information at that moment represented 40% of Europe's heritage and 16% of the world heritage in the field of musical instruments.

After the end of the EU funding, the museums continued their cooperation. Today, the original MIMO group has grown into a consortium of 33 partners, with new collections from Norway, the Netherlands, Poland, Spain, China, Burkina Faso and Congo-Brazzaville, among others. Content is available in English, French, German, Dutch, Italian, Swedish, Catalan, Chinese and Polish. MIMO has grown from a European to a global database in 2017, with data from nearly 65,000 instruments. The construction of an additional interface with a faceted search ( made MIMO more user-friendly for the general public.

The MIMO portal is a never-ending project, and is in continuous progress. Working with so many different partners puts forward challenges on the level of homogeneity and uniformity in the identification and name giving of the instruments. Work groups are created and new subprojects are started to improve, control and enrich the ever-growing mass of metadata.

Bringing together so many objects in a controlled and user-friendly environment makes mutual comparisons easy and attractive: evolution and migration of instruments can be discovered and followed. MIMO has become not only a documented catalogue of musical patrimony but also an important tool for scientific research. It is a growing reference center of musical instruments worldwide, a research laboratory where the exchange of information and know-how on musical instruments leads to a significant enrichment of these vehicles of world heritage.

The MIM is part of MIMO's Core Management Group and is, together with the Philharmonie in Paris, responsible for the thesauri:  the Philharmonie for the technical implementation, the MIM for the content.
