ODIN is a system that supports the incremental pay-as-you-go integration of data sources into dataspaces and provides user-friendly querying mechanisms on top of them. We describe its main characteristics and underlying assumptions, including the user interactions required. Odin’s novelty lies in a largely automated bottom-up approach (i.e., driven by the sources at hand) that includes the user in the loop for disambiguation purposes. The on-site demonstration will feature an ongoing project with the World Health Organization (WHO). Online demo and videos: www.essi.upc.edu/dtim/odin/
