[kea-dev] Licensing of Yang models

[Roman Mashak]

Hello,

KEA Dhcp comes with Netconf support and a handful of Yang modules in
https://gitlab.isc.org/isc-projects/kea/-/tree/master/src/share/yang/modules

However, I could not find under what license the Yang modules are
distributed. Is it the same as the KEA-Dhcp package (i.e. Mozilla
Public License v2.0)?

What happens if I modify the shipped Yang modules, or add a new one,
am I supposed to return the changes in the open source community?

Thanks!
