The ROBOT release workflow. A typical release workflow using ROBOT. The ontology edit file ONT-edit.owl is first verified as a quality control check with ROBOT ‘verify’. Then, text files containing lists of external ontology terms in the imports directory are used to regenerate import modules using ‘extract’, ensuring that the imports are up-to-date. ONT-edit.owl is then passed through a series of ROBOT commands (‘reason’, ‘relax’, ‘reduce’, and ‘annotate’) to generate the release, ONT.owl. Finally, ONT.owl is converted to OBO format
