June 2026: Delivered Datafiles Metadata Schema Validation in SciCatProject/scicat-backend-next, enabling automatic validation of datafiles metadata against defined schemas to ensure data integrity and governance. This enhancement reduces ingestion errors, lowers manual validation effort, and improves reliability for downstream analytics and reproducibility. Highlights include the single commit implementing the schema validation and setting the stage for scalable metadata governance across the backend.

May 2026 monthly summary: Delivered security-driven UX improvements and dynamic configuration capabilities across frontend and backend, with a focus on reducing user friction and hardening access controls. Delivered features include: 1) User Authentication and Session Recovery Flow on frontend with AuthInterceptor that redirects on session expiration, a session timeout action to clear state, and login redirect back to the original page (commit df01bea2897e311d126c066680369c5ec77a896b). 2) Dynamic Variable Resolution for Configurable Actions on frontend to support recursive variable resolution for action items, enabling dynamic dependencies (commit bdcbc895808489129e5e58a2dc4016b2a1f7e1e5). 3) JWT Authentication Guard on backend that throws a 401 session expired error for expired tokens, strengthening security (commit d40cd0369a37598707202c0fe52cb027706d2502).

Monthly summary for 2026-04 across SciCatProject/scicat-backend-next and SciCatProject/frontend focusing on data flexibility, instrument governance, and user experience consistency. Backend enhancements introduce an optional DataFile metadata field and an Instrument PID posting option with validation and data exposure adjustments. Frontend improvements add a configurable timezone (UTC default) to ensure consistent date/time handling and implement a configuration-driven UI toggle for sample metadata edits. These changes improve data management, reduce entry errors, and support operational workflows across data capture, instrument management, and metadata administration.
