Music archives are home to a treasure trove of audio. And the contents are not only music – videos, books, documents, manuscripts and musical instruments are all part of Europe’s cultural heritage. But due to lack of interoperability between data catalogues, this material often lies hidden from the outside world. The two-year EU-funded project initiated in September 2006, addresses the problem. Partners will provide copies of their metadata to be made available via the DISMARC website, and all data will be searchable from one point of access.
