Planning:

• We want to get the code to run the demo into master by the end of this week (Week of April 8)
• After that we add more entrypoints / make entrypoints more robust
• Time estimate: @pcrespov @bisgaard-itis spend 2 week on this, @wvangeit til the end of the month (in combination with metamodelling in s4L brainstorming)

I think this example (https://github.com/wvangeit/osparc-pyapi-tests/blob/master/noninter1/README.md) defines very well the workflow to complete this issue. I will create a test to have a measure of completion.

FYI, I just realized that this script didn't have 'delete the job' yet. I added it.

I'm closing this, since we merged the metamodelling into master. I've moved the nice-to-have tasks and problems in the underlying platform to https://github.com/ITISFoundation/osparc-issues/issues/1407
