Smart Data Models are openly licensed. It means that nobody is asking you for anything to use them. Indeed it is possible to modify the models and share them.
Anyhow if you are interested in getting some dissemination because you are using them, check the new menu entry (I am already using it!) with a form in which you can be listed as an adopter and get in return dissemination on LinkedIn, Twitter, and in the smart data models blog.
