Hello @lucas-givord , why did you remove the folder 'src' in your architecture?

All other geosPythonPackages projects like geos-posp, geos-mesh etc ... have the same architecture of:
"geos-feature/src/geos/feature/" instead of what you used with "geos-trame/geos-trame/"

What is your view on this ? @paloma-martinez

[lucas-givord]

I didn't know that all other geos packages follow this structure, at least for consistency I should do the same thing.

Initially, I switch to a flat layout for simplicity but following an src/package layout is also nice (for installation step). The "geos-feature/src/geos/feature/" seems to be a variant of the src/package layout, by curiosity what is the rational to do that or is it a convention?

[paloma-martinez]

I think the "geos-feature/src/geos/feature/" layout allows to define and use geos namespace... You're right @alexbenedicto, it might be better to keep the same architecture for all packages in the repository...
