The file format is open and has been adopted by other 3D graphics application vendors, making it a universally accepted geometry file format. The OBJ file format is a simple data format that represents 3D geometry alone - namely, the position of each vertex, the texture coordinate associated with a vertex, the normal at each vertex, and the faces that make each polygon.
