June 2025 (2025-06) monthly summary: Delivered two major feature areas in mxcubecore with strong business value and improved reliability. First, metadata enrichment and EDNA/LIMS integration with ISPyB compatibility, enabling richer metadata collection from diffraction and processing plans, retrieving sample data from LIMS, downloading reference resources, and extending the EDNA workflow with sample data. This enhances end-to-end sample tracking, reduces manual data handling, and improves interoperability with downstream ISPyB processes. Key commits include: 6dc7bd956cb83b32ad26e215ff104bb8c54b8376 (1182 add diffraction and processing plan to metatadata), f6d5ed22c69a29f00007e80628790934f4814382 (Added sample to the parameters to be passed to edna), ac2446bd2f8da68bf5f936e65ce5579760042d64 (Added sample to the parameters to be passed to edna). Second, ICATLIMS session handling improvements and code quality/refactor, refining session selection with only_staff_session_selection control, handling staff-only sessions with warnings when no active session, removing debugging statements, and deploying production-ready defaults. This increases stability of data access layers, reduces operational risk, and improves maintainability. Key commits include: 0b25feedc27f46fd0b00a660481ae71fdc826857 (this fixes #1294), c720fb0f2633707e1d077cdc3fdbe4d4aa5e664c (this fixes #1294), 73b63db25ccefe902dc14b0a9456c8b411d23c8d (Cleaned up the code). Overall impact: strengthened data lineage and interoperability, improved developer productivity through cleaner code and production-ready defaults, and a more reliable foundation for ongoing feature work. Technologies demonstrated include EDNA integration, LIMS/ISPyB interoperability, and targeted refactoring for code quality and session management.
