Research Projects

DOREMUS/ANR 2014-2019 : Expansion of FRBRoo ontologies for the representation of works of music, their interpretation, and associated events. The project enabled the creation of an open musical knowledge graph that integrates and links data from the Paris Philharmonic, the French National Library and Radio France, as well as the creation of recommendation services.

DataLift/ANR 2010-2013 : Tools and methodologies for facilitating data publishing in Linked Open Data formats

Professional Committees and Groups
