The next component of the FAIR principles is the Accessibility of the research workflow, ideally without any legal, technical, or financial barriers. This requires a working workflow version, readily available for download from a domain-specific repository or web interface, and licence information, even when the associated workflow is not open-access. FAIR digital objects are not always associated with open data formats or software depending on the research and the licence applied to it, so the information on authentication and authorisation should also be provided if required.
