Process Package generation from Jupyter Notebook definition

[fmigneault]

Explore the possibility to simplify the generation of new process packages directly from a notebook.

Points to explore (non-exhaustive list) :

• using typing definition in a main function to define/auto-detect the I/O of the CWL package, and therefore the WPS process.
• defining automatically a new docker image with added python package requirements as specified by the notebook

Good candidate for notebook → CWL generation

IPython2CWL

• https://github.com/giannisdoukas/ipython2cwl
• https://ipython2cwl.readthedocs.io/en/latest/
• https://github.com/giannisdoukas/ipython2cwl-demo
• https://gitter.im/ipython2cwl/community

To Do

• provide deploy from Jupyter Notebook URL or Git URL
• add README references to relevant OGC Testbed-16: Earth Observation Application Packages with Jupyter Notebooks Engineering Report (http://docs.opengeospatial.org/per/20-035.html)

Instead of managing Notebook to CWL conversion in Weaver, dispatch the operation to jupyter-repo2docker as demonstrated with https://github.com/crim-ca/ncml2stac

• Update documentation to add a section demonstrating the capability with a pointer to the above example and relevant utilities

Provide a reference to https://github.com/Terradue/click2cwl (see also GD-464) which can be used when interacting directly with Click CLI rather than Jupyter Notebooks.
