On theSindex it has a DataRank of 0.992, placing it in the top 20.5% of the data-sharing corpus. It has been cited 26 times, with 26 citing works in its 1-hop citation network. Its calibrated FAIR score is 4/100.
Ranks in the top 20% 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.
