This report attempts to give a general overview of the complex data requirements by the research work packages and proposes a methodology for further identifying data gaps. This analysis and an informal preliminary investigation during the kick-off meeting allowed us to address the first gaps (Stygofauna Mundi, European fishes, odonates, ...), as well as further requests along the project. For the second period, we analysed how much the contingency funded projects covered the data requirements.
