June 2025 (2025-06) – Key outcomes focused on delivering Groovy-based test fixtures for eOverdracht-HEO FHIR Task tests and cleaning up the test infrastructure/build paths to improve maintainability and reliability. Delivered a Groovy Task Fixture scripting layer for eOverdracht-HEO that supports creating/manipulating test fixtures based on FHIR Task resources, enabling status changes and alternative transfer dates with support for JSON and XML formats, and updated build properties to reflect new directories. Completed a targeted test infrastructure cleanup and build path refactor to streamline eOverdracht tests, including renaming scripts and removing outdated B/non-B scripts, with corresponding updates to build.properties and directory structure. Overall, these changes enhance test coverage and stability for eOverdracht scenarios while reducing maintenance debt and improving CI reliability.

In May 2025, the team delivered core HL7 mapping enhancements and strengthened test infrastructure, with a strong emphasis on data accuracy, automation, and maintainability. The work improved data readability for organizations, ensured up-to-date FHIR data, and stabilized test execution across multiple scenarios, delivering tangible business value in data integrity, regulatory readability, and release readiness.

April 2025: Major data-model and refresh-system uplift for HL7 mappings. Delivered refactored FHIR instances refresh and ADA 2 FHIR refresh, added Organization element, Procedures endpoints, ContactPerson resources, and multi-participant support, while removing RelatedPerson from the data model. Implemented a robust data synchronization and refresh system with distinct and combined refresh paths for FHIR and ADA, plus a dedicated update path for FHIR instances.
