The question was about the coordinate system used by your software, i.e. which directions point x,y,z relative to device orientation? And how is your world coordinate system looks like in this context. This is important for proper use of accelerometers, gyros, magnetometers.
The MetaMotion R documentation has axes labeled (pg 5) which should be the same for all of the rectangular boards except MetaWear R. A simple way to double check is to use the real time graph in the MetaWear app to see which axes are around +/-1g while resting the board on all 6 sides.
