VIDS Directory Structure (v1.0)

A VIDS dataset is organized as a dataset root containing required metadata files, subject/session trees, and a derivatives tree for annotations.

Dataset root (required elements)

A compliant dataset root includes: .vids, dataset_description.json, participants.json or participants.tsv, README.md, sub-* subject directories, and derivatives/annotations/.

Full profile additionally requires quality/ and ml/.
