DataBridges work focuses on two main topics: (1) the interoperability, enrichment and personalization of data, e.g. data on the cultural activities within a city, based on uder profiles, (2) efficient techniques for large-scale RDF data management, to be applied (among others) on digital city data. This is the funding of the Databridges project for INRIA Saclay Île-de-France (Leo team).
