BIDS Extension Proposals
The BIDS specification can be extended in a backwards compatible way and will evolve over time. This is accomplished with BIDS Extension Proposals (BEPs), which are community-driven processes (see BEP guidelines Google Doc).
On the BIDS homepage you can find a list of extension protocols that are currently being worked on.
All changes that are not backwards compatible with the current BIDS
specification will be implemented in BIDS 2.0
. See the corresponding
Google Doc
