The individual steps and metadata of the workflow should use defined FAIR vocabularies, which can be domain-specific and should have identifiers to link them to the description of the terms. This ensures the findability and accessibility of the vocabulary used in the workflow. In the case of MAW, we employed the EDAM ontology for the .mzML file. The RO-Crate profile generated by WorkflowHub also collected the metadata using defined Schemas (BioSchemas) to represent workflow-relevant provenance.
