The S-Index (Sharing Index) is a comprehensive metric that represents the cumulative impact of all your datasets. It is calculated as the sum of Dataset Index scores across all your claimed datasets.

What it means:

• A higher S-index indicates greater overall impact of your datasets relative to typical datasets in their fields of research
• The S-Index grows as you add more datasets or as existing datasets gain more citations and mentions
• It provides a single number to track your research data impact over time

Current S-Index: 0.7 (sum of 2 datasets Dataset Index scores)
