Analysis-friendly snapshots of participant-authorised, de-identified platform data—with stable match codes, explicit exclusions and a codebook beside every release.
The monthly library never quietly blends records from different consent histories.
EXTERNAL REFERENCE
100K historical comparison sample
Used on the SDO feedback page as aggregate distributions with its external provenance and convenience-sample limitation stated. It is not a YWID participant-level public release.

New platform contributions
Only data gathered by this platform with a current explicit open-science permission can enter the automated monthly release.
Eligible for the public catalogue after disclosure controlsRESEARCHER PROJECT
Study-specific collections
Data from researcher-built studies stay in their governed project workspace and never enter the public core automatically.
Private by default and purpose-bound
PUBLIC BY DESIGN, LIMITED BY DESIGN
A useful core—not a data dump.
The public collection is deliberately smaller than the private research record. It contains only the fields needed for common secondary analyses.

Age band
Gender category
Continent
Raw SDO item responses
Derived SDO scale scores
NEVER IN THE PUBLIC FILE
Name, email or account ID
Internal participant or session ID

ONE RELEASE · TWO LEVELS
Start small. Link only when needed.
Most analyses need only the participant-by-item core file. A separate long-format behavioural file holds approved study interactions and timing. The same temporary match_id links them within that month’s release.
PRIMARYCore data
One row per completed SDO measure. Demographics, 16 item responses and scale scores.
match_idOPTIONALBehavioural data
Long-format item latency, answer revisions and whitelisted interface events. No event payloads or exact times.
RELEASE LIBRARY
Cumulative monthly snapshots
Each release freezes all eligible platform-core submissions received before the stated cutoff. Researcher-created surveys never enter this pipeline.
01EligibilityOnly completed platform-core records with a current, explicit open-science opt-in are selected.
02MinimisationIdentity, exact dates, detailed geography, free text and non-core research fields are removed.
03Disclosure reviewNo public file below 100 records; demographic combinations below 5 are blanked.
04ReleaseA new monthly match-code salt, immutable CSV objects and documented metadata are created together.
RESPONSIBLE REUSE
Open does not mean unrestricted.
These prototype releases are for non-commercial research under CC BY-NC 4.0 · non-commercial research use. Users should cite the release month and schema version, avoid re-identification attempts and report disclosure concerns to the platform steward.
