Implementations of protocols should be encouraged to interoperate.
Thus GMPG has chosen to use the (cc) nd license restriction for its protocols and formats to reduce mutability into non-interoperable forms.
Social
Human user centrism
Humans (especially users) first, machines second. Technologies must be first designed for ease of use (including authoring) and human understanding, and only second for ease of development and machine understanding.
Similar to the W3C's principle of "consensus", the GMPG's designs/decisions are made by unanimity among the Founders.
New Assembly
The GMPG believes there are many opportunities to launch new efforts, and thus encourages others to do so as well. Feel free to use this set of principles as a starting point — it is licensed under the Creative Commons (by) License which of course allows for derivative works.
Economic
Profit and prosper
Enable people to build and sell products, without obligating them to divulge their intellectual property. Thus GMPG does not include the (cc) nc license restriction on any of its efforts, nor does it contain any so-called "viral" provisions. May you profit and prosper.

Note that many of these sources contain many other principles, some of which were perhaps not important enough, and some of which could even be considered counter-principles. It is left as an exercise to the reader to determine which are which. In no particular order:
