The project entails the digitization, documentation, and promotion of ethnomusicological sound and audiovisual archives conserved at the National Library of France (BnF), the Quai Branly Museum, and the Center for Research in Ethnomusicology (CREM) of the Laboratory of Ethnology and Comparative Sociology (LESC). The objective is to pursue the digitization and documentation of emblematic archival collections (great scientific events, exhibitions, and producers), and to make them available to different audiences by creating links between complementary but disparate collections. On this occasion, a common ethnomusicological frame of reference (music instruments, voice, dance, etc.) will be developed, thereby constituting a first step for the sharing of data. What is at stake with this project is the facilitation of access to these heritage collections, the wider distribution of the world\textquoterights oral musical traditions, and innovative modes of digital access through semantic network and linked data. Building on this first step, other French and European institutions with similar collections can become program partners.
