The Interactive Platforms for data integration will allow users to interact simultaneously with different sources of data to create derived services. The base of the development will be a generic purpose platform that can be customized according to specific needs. The expert platform will be able to exchange information with different modules using the standard protocols defined i n WP2. This generic platform will incorporate micro services that will allow the external users, use or integrate each service in their own i nstitutional or professional web platform. To develop this platform, the first task that we had to tackle was to create a common framework that helps us and helps others to build their own Biodiversity Observation Expert Portal. This portal provides very interesting functionalities for the community, and solves several problems that have arisen i n recent years due to the increase in the number of Citizen Observatories (COs) that have been created without following common rules.
