Purpose of the Study:

• To highlight the suitability of electronic laboratory information management systems (LIMS) for managing macromolecular crystallography workflows.
• To emphasize the importance of capturing and exchanging metadata according to FAIR principles throughout the crystallography process.
• To present a specific LIMS, IceBear, as an example for implementing these data management features.

Main Methods:

• Describing the established workflow of protein crystallography from crystallization to structure deposition.
• Discussing the data management requirements for complex, multi-user crystallography projects.
• Illustrating the implementation of metadata capture and exchange features within a LIMS.

Main Results:

• An electronic LIMS is well-suited for managing the entire protein crystallography workflow.
• Key features for capturing and exchanging metadata are crucial for data integrity and reproducibility.
