The S-Index summarizes how consistently a researcher's datasets meet the selected SHARE score threshold, analogous to the h-index for publications.
Definition: A researcher has an S-Index of n if they have n datasets with a score ≥ n. The legacy deposit-time score uses S+H+A+E and reports downstream reuse separately.
S-Impact: A citation-based outcome metric for shared datasets.
S-Index (Unique): S-Index after collapsing series/temporal deposits into unique concepts via title normalization.
