Sustainability Roadmap between DataJoint Elements and DANDI Archive



DataJoint Elements and The DANDI Archive (DANDI) are two neuroinformatics initiatives in active development. The projects develop independently yet they have complementary aims and overlapping user communities. This document establishes key processes for coordinating development and communications in order to promote integration and interoperability across the two ecosystems.

Projects and Teams


DataJoint Elementshttps://elements.datajoint.org — is a collection of open-source reference database schemas and analysis workflows for neurophysiology experiments, supported by DataJointhttps://datajoint.org — an open-source software framework. The project is funded by the NIH grant U24 NS116470 and led by Dr. Dimitri Yatsenko.

The principal developer of DataJoint Elements and the DataJoint framework is the company DataJoint — https://datajoint.com.

Neurodata without Borders (NWB)

DANDI - https://dandiarchive.org — is an archive for neurophysiology data, providing neuroscientists with a common platform to share, archive, and process data. The project is funded by the NIH grant R24 MH117295 and led by Dr. Satrajit S. Ghosh and Dr. Yaroslav O. Halchenko.

The principal developers of DANDI are at the Massachusetts Institute of Technology, Dartmouth College, Catalyst Neuro, and Kitware.

General Principles

No obligation

The developers of the two ecosystems acknowledge that this roadmap document creates no contractual relationship between them but they agree to work together in the spirit of partnership to ensure that there is a united, visible, and responsive leadership and to demonstrate administrative and managerial commitment to coordinate development and communications.

Coordinated Development

The two projects will coordinate their development approaches to ensure maximum interoperability. This includes:

Points of Contact

To achieve the aims of coordinated development, both projects appoint a primary point of contact (POC) to respond to questions relating to the integration and interoperability of DataJoint Elements and DANDI.

For 2022, the DataJoint Elements POC is Dr. Chris Brozdowski

For 2022, the DANDI POC is Dr. Satrajit Ghosh

Annual Review

To achieve the aims of coordinated development, the principal developers conduct a joint annual review of this roadmap document to ensure that the two programs are well integrated and not redundant. The contents and resolutions of the review will be made publicly available.


The two parties ensure that relevant software components are developed under licenses that avoid any hindrance to integration and interoperability between DataJoint Elements and DANDI.
