Do you have expertise or experience to share on what software license can be used to share a model created in ArcGIS ModelBuilder to ensure that it is free to use, or used for non commercial purposes.
I am currently looking at the GPL v3 license, but since the model is based on using ArcGIS software I am not sure if this is appropriate.
UPDATE
I should have added for clarity. We wish that although the Models are free to use that there is the ability to restrict commercial use (which may then be under a different license) We wish to be able to ensure that any edits or improvements to the Models are also made available and free to use.
