Convert Galaxy workflow files to (abstract) CWL

• This is a standalone tool that creates CWL-abstract descriptions of Galaxy workflow runs or Galaxy workflow files (static files).
• Initially the output will be an abstract version of a CWL workflow (aka cwl-interface, see https://github.com/common-workflow-language/common-workflow-language/issues/337 and https://github.com/common-workflow-language/cwl-v1.2/pull/3). As the CWL support in Galaxy increases then conversion could come up with a full CWL workflow file.

Examples

A simple workflow in Galaxy format can be found in examples/simple_workflow_galaxy.ga To convert this to a CWL-interface The resulting CWL-interface can be found in examples/simple_workflow_cwl-interface.cwl

• The main use case initially would be to create ro-crate objects for 2 cases:
  • for workflow executions: I would have the cwl-interface representing the CW:-PROV data. and also the galaxy workflow definition file? or any other info from galaxy?
  • for workflow definitions: I will have of course the workflow definition file in galaxy format, and a cwl-interface created from it.
