Model Archive Format for X3D

There are formats that have been around a long time (OBJ, FBX, X3D), those that are optimized for delivery (glTF), those that are widely used in existing tool chains (OBJ and FBX), plus a number of other criteria and formats including tool-specific (Blender, Maya, etc.).
