The NIXIO module is the native python re-implementation of the NIX C++ library for the NIX data model.

The NIX data model allows to store fully annotated scientific datasets, 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 or the introduction for more information.

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

NIX emerged from the activities of the Electrophysiology Task Force of the INCF Datasharing Program (2010-2015). It is a registered research resource with the RRID:SCR_016196.


We have assembled introductory material that illustrates using nix. The tutorials contain several code examples. The use_cases explain in more detail how nix is used in real world situations.

If you use NIX, it would be much appreciated if you would cite it in publications with its identifier RRID:SCR_016196 and/or the reference:
