Tryton, OpenProject and PM²

I recently saw the news about a partnership between the PM² Alliance and OpenProject

Does anybody know what the partnership really means?

Would Tryton also make the same partnership with PM² Alliance, in particular, can PM² be implemented in Tryton’s Project module?

Any simple hint about what PM2 really means ?
Do you have any use case ?

Even less understanding after reading the site

There is a wikipedia page about PM² and that has links to more resources.

You can request a download copy of the official PM² guide at this page by giving your name and email address.

There is also a wiki operated by the EC, it also requires registration to read it
