So far the SDIs are portals where a group of authoritative experts publish data of public interest. However, with the advent of smartphones and the multiplication of sensors in our environment, there is a demand to publish collaborative data on these platforms. Is it possible to combine both systems? Will these collaborative data be useful? How can we ensure that the data have enough quality? So many questions to answer within a research project from the European Commision: Cobweb. Cobweb tries to build a solution for smart cities and citizen science (also smart rural). Focused on the usecase of research around Biosphere Reserves and endangered species, we are combining different technologies to ensure not only that arbitrary data can be easily collected on the field but also that there is a conflation and quality assurance process where data is classified and prepared for later use. Security and privacy of personal details are also part of the project.
