Another complication arises from the practicalities of experimental lab work: the state of the sample might be modified by user intervention outside of the scope of an AiiDA workflow. The current gold standard in lab practice is to track all activities in the lab in a lab book, which then contains the full authoritative sample history. Interfaces between electronic lab notebooks and WFMSs, and their wider adoption, are necessary to fully address this issue; such an interface will be discussed in a further work.
