Provenance — who produced it, who reused it
Linked to 1 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Deep data QC
100/100 · AStandardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured
Environmental amplicon sequencing of unspecified marker genes via Illumina MiSeq with 902,000 reads across 18 files at 97% Q20 and 90.6% Q30. The small per-file read counts and 54.6% GC suggest targeted community profiling (16S rRNA or equivalent). Users should clarify the amplicon region and whether this dataset is suitable for alpha/beta diversity inference given the modest sequencing depth per sample.
The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
