Shared Near Infrared Spectroscopy Format (SNIRF) is designed by the community in an effort to facilitate sharing and analysis of NIRS data.
The specification can be found on GitHub here. Version 1.0 was released in November of 2019. You can find the specification, software, and sample files through GitHub.
Finally, we have launched a SNIRF list server. You can signup through our mail chimp server here. This mail server is likely to be used infrequently as most communication will happen through the github page.
