Other resources with metadata, such as keywords, include the GitHub repositories or the published research articles. For MAW, we have used the following terms as keywords to describe the workflow in the publication: "Untargeted metabolomics", "Workflow", "Tandem mass spectrometry", "FAIR", and "Metabolite annotation". A descriptive title and workflow summary are also required to make it more user-friendly. We used the title "Metabolome Annotation Workflow", which describes the main task of the workflow, "to provide structural annotations to metabolomics data". A workflow summary and a detailed description of the different functions within the workflow are described in the README.md markdown files archived on Zenodo () .
