This deliverable addresses the request by the European Commission to establish a data management plan. It is intended that this plan will evolve over the project duration. This present document constitutes the 2nd version of the data management plan, which provides overall guidelines and a basis for further evolution before the end of the project. In particular, it covers the question of data identification, data description, standards and metadata, data sharing and data archiving. In the IBISBA 1.0 project, a complete workpackage is dedicated to the development of e-tools for data and knowledge management and the project is operating a data management hub in cooperation with the Fairdom initiative, a leading European association that promotes the principles of data FAIRization (i.e. making data Findable Accessible Interoperable Re-usable).
