Dec 1, 2024December 2024 performance summary for IQSS/dataverse focused on strengthening archival metadata management and metadata customization workflows, with clear traceability and release-oriented documentation. Delivered two major features with targeted configuration and guidance improvements, supported by commit-level changes and release notes. Implemented fixes to configuration handling to reduce ambiguity and improve consistency, setting the foundation for broader metadata governance. Key accomplishments include: - Centralization of archival metadata configuration via archival.properties and standardization of boolean representations (true/false). - Introduction of an experimental Archival metadatablock with related property refinements to enhance archival metadata modeling. - Enhancement of the Metadata Customization Guide to support boolean field types (True/False, Unknown) and boolean vocabularies, improving usability for data curators. - Release notes added for both features to improve transparency and onboarding for users and implementers. - Minor fixes in archival.properties to improve consistency and reduce interpretation ambiguity in configuration.
