Assigning a Persistent Identifier to the workflow (F1) Assigning a persistent identifier (PID) is the first component to make the workflow "F"indable. PIDs are unique and permanent identifiers assigned to digital objects to ensure longevity. Many workflow repositories automatically provide a PID, such as a DOI, during submission. Submitting the workflow to repositories prevents the workflow from potential changes or discontinuation of its original hosting platform. In the case of MAW, we linked the workflow code repository to WorkflowHub (details on submission below in F4), which then was used to generate a DOI ().
