Validation Evidence

SRA High Compliance: Mean SHARE 84.7 with fixed /25 denominator scoring, validating that enforced standards produce high scores
Zenodo Distribution: Normal distribution centered at 35, showing natural metadata variation
OpenAIRE Scale: 73.4M records demonstrate framework scalability
ClinicalTrials.gov IPD Gap: Trials declaring Individual Participant Data sharing score significantly higher than those without
Cross-Repository Comparability: Same signals scored identically across all repositories
