Hey there! I’ve started writing a guide for using CWL in the Earth Observation domain. My goal is to provide working examples of CWL to use typical EO tools and toolboxes. I hope this eases the CWL adoption in EO. Everything is hosted here: [Common Workflow Language resources for Earth Observation · GitHub](https://github.com/cwl-for-eo) It’s definitely a WIP at this stage. Here’s an example of what I’m targeting: [Sentinel-2 NBR - Guide for CWL in Earth Observation](https://cwl-for-eo.github.io/guide/workflows/sentinel-2-nbr/) ---

This is great @FabriceBrito , thanks! I sent a pull request and opened an issue about some potential simplifications to the example CWL descriptions you have shared. ---

Thanks @mrc ! I’ll update the other CWL examples.
