Figure : FAIRification scheme for MAW. WorkflowHub, a workflow registry, is the foundation to enable FAIR-supporting workflows. Metabolome Annotation Workflow (MAW) is described using Common Workflow Language (CWL), which supports the FAIRification process and is WorkflowHub's preferred format. MAW is Findable; the workflow metadata is packaged as a workflow RO-Crate object, which includes BioSchemas markup to enable its findability across the life sciences web. MAW is Accessible and archived with WorkflowHub versioning system linked with a DOI. MAW is Interoperable; it is described using CWL and employs Docker-format software container images to set up a deployable environment across different systems. cwltool, the reference implementation of CWL, can also act as a workflow runner, as well as other workflow engines that support CWL, such as Toil and Streamflow . MAW is Reusable; the contextual metadata and tutorial on the usage of MAW are archived on Zenodo, with the source code and a software licence. MAW's Interoperability and Reusability aspects are defined first and submitted to the WorkflowHub, enabling Findability and Accessibility.
