Inventory every dataset supporting your figures and conclusions, classify each into an access route such as public repository or controlled access, then draft the statement with explicit dataset-to-location mapping. Include repository names, accessions or DOIs, and licences, and add formal dataset citations for reused public data.

State why open sharing is impossible, name the access committee or institutional route, and describe eligibility, ethics approvals, or data-use agreements. Provide a public metadata record or representative data where possible instead of writing only "available upon request".

It is treated as weak unless justified by a specific legal, ethical, commercial, or third-party restriction. The statement must name the responsible access body, eligible requesters, review conditions, and any public metadata to be durable and acceptable.

Use a mandated repository when the data type requires one, otherwise a discipline-specific community repository, and fall back to a generalist or institutional repository with DOI support. Avoid personal websites or temporary cloud links as the only access route.

It verifies the dataset has a persistent identifier, rich searchable metadata, standard formats, a licence, provenance, and a README documenting variables, units, and processing steps. DataCite core fields such as creator, title, publisher, year, and resource type are also checked.

No. It never fabricates accessions, DOIs, licences, repository records, or access restrictions. When information is missing, it returns a usable draft plus a short confirmation checklist of fields the author must supply.
