May 2025 performance summary for HL7/fhir: Executed a targeted terminology cleanup and stability drive, restoring and aligning critical CodeSystem/ValueSet assets for Evidence, while moving codesystem definitions out of the base FHIR specification. Updated EBM terminology URLs and references to improve interoperability and build reliability. Expanded data models with ResearchStudy and ResearchSubject enhancements, adding elements and roles (including ResearchStudyPartyRole) to support richer study metadata and governance. Implemented data-monitoring enhancements and documentation updates to strengthen data quality signals for ResearchStudy workflows. Added endpointAnalysisPlan references to ResearchStudy.objective.outcomeMeasure and aligned THO bindings for Composition.relatesTo.type, along with structural updates to related definitions. Updated Questionnaire examples to UCUM lb_av and refined related profile files. Executed several small fixes (indentation, batch corrections) to tighten the overall code quality.
