About NIX

The NIX project started as an initiative within the Electrophysiology Task Force a part of the INCF Data sharing Program. The NIX data model allows to store fully annotated scientific dataset, i.e. the data together with its metadata within the same container. Our aim is to achieve standardization by providing a common/generic data structure for a multitude of data types. See the wiki for more information

The current implementations store the actual data using the HDF5 file format as a storage backend.
