This is an announcement of a BIDS Extension Proposal for BIDS Applications and execution descriptions. This BEP is intended to supersede the BIDS Apps paper (doi:10.1371/journal.pcbi.1005209) and build upon our experience over the last 3 years or so of application development and deployment.

I believe the next available BEP number is 27. If there are no objections, I will open a pull request adding this as BEP027.

• BEP draft

This document is a partial draft, with some need to flesh out some details, but I think the broad outlines of what we're trying to do are here and ready for broader comment.
