Flexible and customised data management and sharing solutions are in demand in many projects being publicly funded or deployed in-house at a specific institution. Edelweiss Connect offers data management components that can be combined to form a complete data solutions for internal or public sharing of complete data collections or for bringing single datasets into the NanoCommons ecosystem, preserving privacy and confidentiality if needed. The solution offers full interoperability with the semantic model of the NanoCommons Knowledge Base (KB) and, in this way, allows for the full integration of the new data opening up all features of the KB like cross-database searching and browsing. In addition, the automatically generated APIs allow for linking of the data with the corresponding protocols as well as direct integration of the data into the analysis and modelling services of NanoCommons, or other external analysis and modelling tools. The ACEnano data warehouse, also available as a NanoCommons service, is the first example of a data sharing solution based on this technology.
