In this demonstration we will introduce the BExIS 2 research data management platform. BExIS 2 is the completely redesigned and refactored successor of the earlier Biodiversity Exploratories Information System (BExIS), which was established in 2007 as the data repository and information exchange platform for the Biodiversity Exploratories project (40+ sub-projects, 300+ researchers). Over the years BExIS has been adapted for additional large scale projects in functional biodiversity in Germany (e.g. Jena Experiment, Kilimanjaro, EFForTS). With the growing community not only the list of requested features rose, also the demand for a more flexible and easier to instantiate system grew. In 2011 we started to revamp the system based on a newly designed architecture to be more generic and meet modern software standards in terms of scalability, modularity and interoperability. Following the data-life-cycle concept BExIS 2 provides modules for data collection, data discovery, dissemination, integration, quality assurance and research planning. BExIS 2 is geared towards large scale cooperative projects in biodiversity research. Key features of the current BExIS 2.4.0 system include: support for a broad range of data structures and data types, support for multiple database management systems (e.g. PostgreSQL, IBM DB2), a faceted search on metadata and primary data, customizable data downloads and a highly flexible security system. New features are being developed based on requests from the user community and released every three month under a GNU General Public License (version 3). The development of BExIS 2 is being funded by the German Science Foundation (DFG) as part of the BExIS++ project (http://fusion.cs.uni-jena.de/bexis). Funding for specific extensions and modules is further provided by DFG through the projects: BExIS, AquaDiva, GFBio and iDiv.
