In every interdisciplinary, long-term research project, which focuses on environmental field studies and regional modeling, it is a key issue to collect, store, backup, and exchange data. Therefore, the overall success of such a project depends on a well-organized data management. This has to contain the organization of all project data, the implementation, and the maintenance of a system that also encourages intensive data exchange between all involved project sections. Consequently, the sustainable use of all research results during and also after the end of the project is ensured.
The scientific data management system of the TRR228 (TRR228DB) is developed following the guidelines of the DFG. Due to the various disciplines, the TRR228DB has to handle a huge amount of various research data from different research fields and scales (laboratory to catchment scale). Besides diverse collected research data (including measured and modelled data), publications, presentations, reports, and pictures provided by the TRR228 participants, also purchased geodata from various institutions are considered.
The TRR228DB offers several functionalities. These are for example management, centralized, sustainable storage and backup, visualization, exchange and provision of TRR228 data for all project participants. Furthermore, the linkage of all project data with adequate and specific metadata depending on the type of data and also related to the TRR228 context is provided. All features are accessible online, e.g. representation and search of data via metadata. Some functions are only available for authorized users like download of data, input and modification of corresponding metadata, application of specific TRR228-DOIs for datasets, download of purchased and processed geodata, as well as visualization of geodata in a Web-GIS due to license constrains.
