Christophe Mangeat contributed to the georchestra and geonetwork/core-geonetwork repositories by delivering features that improved authentication, metadata accessibility, and code maintainability. He modernized gateway authentication flows and introduced organization-scoped permissions, leveraging Java, Spring Security, and OAuth2 to enhance security and access control. In geonetwork, Christophe implemented anonymous metadata access via generated links, improved multilingual metadata presentation, and integrated DOI support in the STAC harvester, using Java, XML, and XSLT. His work included code refactoring, schema transformations, and rigorous unit testing, resulting in more reliable APIs, better interoperability, and maintainable codebases that address both backend and frontend requirements.
February 2026 highlights two major feature deliveries and one critical bug fix for geonetwork/core-geonetwork, with strong emphasis on business value, interoperability, and reliability. Features delivered: (1) Anonymous metadata access via generated links, including a full create/list/delete API, security filters, and database interactions, accompanied by updated documentation and tests. (2) Metadata processing enhancements: DOI integration in the STAC harvester and conversion from ISO 19139 to ISO 19115-3 with locale-aware indexing and UTC timezone handling, plus corresponding tests and XML schema updates. Bug fix: Metadata view now correctly references the current record in both the full view and side panel, ensuring related resources display as intended. The work was complemented by Swagger/API documentation updates and expanded test coverage.

October 2025 (2025-10) Monthly Summary — geonetwork/core-geonetwork This month focused on delivering robust metadata capabilities, improving data presentation reliability, and strengthening code quality with targeted fixes and compliance updates. Notable outcomes include enhanced CSW support with multilingual transformations, licensing header compliance, reliable UI asset URL handling, and more stable tests. Key areas addressed: - CSW Metadata Enhancements and Multilingual Transformations: schema fixes, improved keyword transformations, multilingual handling, and typeNames-based searches; added tests for CSW output. - Licensing and Copyright Header Compliance: added missing copyright and license headers to two Java test files to ensure license compliance across source files. - Correct URL forging for organization logos: fixed URL forging for logos by using ng-attr-href for xlink:href and updating the image source to an API endpoint. - Stabilize MessageProducerTest to prevent race conditions: refactored tests to ensure thread safety and avoid ConcurrentModificationException. Business value and impact: - Improved interoperability and accuracy of CSW metadata exports, enabling better discovery and data reuse across systems. - Increased UI reliability and correct display of organization logos, reducing user-facing issues. - More robust test suite and license compliance reduce maintenance risk and support audits. Technologies/skills demonstrated: - Java, test-driven development, concurrency handling, front-end integration (ng-attr-href), and REST API integration for assets.
