Get involved in making BIDS better
The easiest way to contribute to BIDS is to ask questions you have about the specification on Neurostars. If your question has a bids tag it will be much easier for others to find the answer.
You can also get involved by answering questions on Neurostars!
You can contribute to the BIDS specification by opening Issues and proposing changes via Pull Requests on GitHub.
To make improvements to the website that you are reading right now, you can also open an Issue and propose changes via Pull Requests at the BIDS website GitHub repository.
There are so many ways to help us build this community. You could help someone else learn the benefits of BIDS, give a talk in your local organization, or build a BIDS App!
The only requirement is that everyone who contributes adheres to our BIDS Code of Conduct.
Thank you for your contributions!
Extending the BIDS specification
The BIDS specification can be extended in a backwards compatible way and will evolve over time. These are accomplished with BIDS Extension Proposals (BEPs), which are community-driven processes.
Do you want to learn more about extending BIDS to a new modality or set of data types? Read the Guide and follow the Submission Process.
You can also contribute to ongoing BIDS Extension Proposals. Below is a table of currently-active BEPs. The “Extension label” column provides a direct link to the documentation.
Please find our latest BEP update presented in the Open Science Room at OHBM.
Note that all of the extension ideas that are not backwards compatible and thus will have to wait for BIDS 2.0 are listed on the Issues page of the bids-2-devel GitHub repository.

Completed BEPs
When an extension reaches maturity it is merged into the main body of the specification. Below is a table of BEPs that have been merged.
The references of the final publication for those BEPS can be found in the BIDS specification.
