Derivatives final request for comments

The BIDS community is preparing to merge the Common Derivatives extension.

~~The updated draft is available for review at X, and comments and suggestions may be submitted on GitHub at https://github.com/bids-standard/bids-specification/pull/265~~.

UPDATE 2021-06-14: The draft is no longer accessible. You can instead look at the stable version

The scope of this extension is establishing a set of common principles for organizing derivative datasets, dataset-level metadata, and naming conventions for minimally preprocessed files. Additionally, some common imaging derivatives (for example, brain masks) have been specified. More detailed modality-specific derivatives are scheduled for inclusion in the next few months.

The final review process entails a minimum of one week for public comment, with a possibility of extension for unresolved discussion. Once public comments are concluded, there will be a one week freeze, during which only critical issues will be considered. (For more details on the release protocol, see https://github.com/bids-standard/bids-specification/blob/master/Release_Protocol.md .)

We look forward to hearing your feedback!
