My proposal is issued to address the following three central issues and other relevant problems: Issue 1: Opening DatasetType to values other than raw and derivatives should have its own BEP. Adding values to DatasetType is a major change to the specification that should be broadly discussed by the community, with a preliminary analysis of potential side-effects by the SG and/or Maintainers. It took a long while before derivatives became a relevant part of BIDS and many years of discussion about them. I contend that DatasetType should keep its special status and be discussed separately. After DatasetType is agreed as the appropriate mechanism, the BEP leads intending to add values should state it when presenting the BEP draft to the SG before it becomes listed as an active BEP. For instance, it would not be crazy to contemplate the possibility of having a DatasetType such as freesurfer, which has a very stable and standardized data structure, to allow it as a standalone dataset. Opening DatasetType means opening BIDS to the creation of standards within the standard. Where to draw the line between raw and derivative has traditionally be a contention point, so enabling more options should be considered very carefully, and provided with prescriptions of how to do it and how to decide beforehand. Otherwise, BEPs proposing new dataset types will creep up as we all tend to think that our area of specialization is special. Please note that this issue does not enter into the actual value of atlas proposed by the BEP. That is reviewed next.

CZI EOSS5 award We will walk through the aspects that have been requested for funding, see what is funded by this grant and what is covered by the R01 that started in June 2021, etc. Elodie is transferring the action items from the project proposal into this GH project: https://github.com/orgs/nipreps/projects/4/views/1In broad terms, the R01 focuses on individual -Preps (fMRIPrep, dMRIPrep, ASLPrep, PETPrep, MRIQC) and underlying neuroimaging developments (e.g., SDCFlows) while the EOSS5 focuses on community building and scientific software engineering aspects.
