bids-schema

Prospective repository of BIDS schema versions (including historical versions), as would be required by validators supporting multiple versions.

At the moment this is just a pilot resource, as schema syntax and validator capabilities are rapidly evolving. Eventually, this repository should become the authoritative BIDS schema resource, including all released versions. It could be used as a git submodule in the repositories of tools which need to use it, incorporated into their tree (fully or partially) via the git subtree mechanism, or distributed separately by package managers.

• The live BIDS schema, as used for all development work, will continue to reside within the bids-specification repository in order to streamline the addition and testing of changes.

• On a regular basis (via cron or push notifications from the bids-specification master branch) this repository should use e.g. git subtree to extract the current schema version and add it to its index.

• Proposed layout (implemented now, but without any copy/release yet):

  • LICENSE
  • README.md
  • versions/
    • x.y.z/ - subdirectories matching schema versions in the BIDS specification
    • latest/ - a copy (symlinks aren't supported on some operating systems) of the most recent release
    • master/ - the state of schema in the BIDS specification master branch repository
  • tools/

HOWTOs

git subtree

See http://github.com/dandi/dandi-core and its README.md for an example of similar (not yet fully automated) subtree use.
