}Workflow language & version
Workflow engine & version (e.g. Toil)
Workflow definition
Input data (or pointers to such)
Parameters? What can be implicit and explicit? (see BCO?)
Tool Dependencies to install (mostly implied by CWL/Nextflow/Galaxy, but might need versions/repos)
Container platform requirement [e.g. Docker, Conda]
Operating system requirement
Hardware requirements (memory, CPU, GPU)
Equivalent of AWS cloud instance type sufficient?
Where to run/submit (e.g. usegalaxy.eu)
Explicit/resolved container IDs
Archive containers from Docker Hub (protect against image expiration)
