Ranks in the top 45% for downstream scientific impact
DataRank reads this dataset's downstream impact straight off the citation graph — no black box, no proprietary weighting. How is this computed?
FAIR checklist signals are shown for context only and do not affect DataRank scoring.
Full FAIR picture · advisory
The headline score is computed from the scored criteria — the fact-shaped checks (a repository, an accession, a licence) that two independent models agree on. The advisory criteria below are real FAIR guidance but rest on judgment calls that models read differently, so they inform without moving the number.
“https://www.blsa.nih.gov/”
The only identifier given is a web URL, which is not a persistent identifier scheme (DOI, Handle, ARK, URN, or repository accession).

“The dataset is publicly available through controlled access by request, pending approval by the BLSA cohort investigators and the NIA research team via https://www.blsa.nih.gov/ .”
The data are hosted on the BLSA website, which is not a named repository in re3data/FAIRsharing, and the holder is the BLSA cohort investigators, not a recognized repository.

“The dataset is publicly available through controlled access by request, pending approval by the BLSA cohort investigators and the NIA research team via https://www.blsa.nih.gov/ .”
The data-availability statement points to a controlled-access request process via a URL, not to a repository record with an accession, so it is partial. [majority verdict 'partial' (3/5 passes agreed)]

“controlled access”
The data-availability statement explicitly labels the access level as 'controlled access', which is a standard access-rights vocabulary term. [majority verdict 'yes' (3/5 passes agreed)]
