The iLog project develops practices and tools to model and track the state of shared inventory items in multi-user laboratories, linking this information to users' Electronic Lab Notebooks (ELN) in openBIS. This supports reproducibility and traceability, especially for complex experimental setups. In this project, we proposed and implemented a data model based on openBIS ELN-LIMS, representing setups as nested objects where components and subsystems are recursively assembled into higher-level systems. We developed and successfully deployed the iLog frontend web application (https://ilog.empa.ch), built using the React UI framework and connected to the openBIS backend via APIs. The production system now features the complete inventory of our pilot lab (Lab 205), where it is actively used. Key functionalities implemented include instrument and component type creation (with inheritance from base types), object registration, historical state reconstruction, and a fully traceable logbook (instrument diary). Initially hosted on Empa servers to support local labs, the project achieved a major milestone in sustainability: iLog will become available as an official openBIS plugin distributed by the development team at ETH SIS in forthcoming openBIS versions, benefiting the broader scientific community.
