PROFILE
Karen Rasmussen
Karen Rasmussen contributed to the hypothesis/h repository by developing and refining backend features focused on annotation management and user customization. She implemented user keyboard shortcut preferences using Python, PostgreSQL, and SQLAlchemy, introducing JSONB-backed storage and validation logic to enhance user experience. Karen also extended image annotation description limits and delivered a robust annotation versioning system, adding version columns, migration scripts, and end-to-end support for version-aware operations. Her work included careful schema updates, search logic refactoring, and comprehensive testing. By enabling both forward-looking versioning and safe rollback to unversioned annotations, she ensured data integrity and maintained backward compatibility throughout.

Apr 1, 2026In April 2026, the team delivered targeted enhancements to annotation versioning while validating backward compatibility by reverting to unversioned annotations where needed. The month focused on delivering a forward-looking versioning capability for annotations, alongside a controlled revert path to maintain stability for existing users and workflows. Key changes include updates to the annotation model, search indexing, and services to support versioning, as well as a safe rollback that unversioned annotations by default when necessary.

Mar 1, 2026March 2026 delivered a major backend feature: Annotation Versioning System for the hypothesis/h repository. Implemented versioning for annotations with a dedicated version column, migration scripts with upgrade/downgrade paths, and end-to-end support for creating, editing, and searching by version. Updated the database schema, search logic, and service methods to handle versioning consistently, with changes cascading to related URI handling and tests. The work improves data auditability, rollback capability, and search reliability across annotation versions, aligning with compliance and data integrity goals.
