Aiming at the increasing requirements of seamless indoor and outdoor navigation and location service, a Chinese standard of <i>Multidimensional Indoor Location Information Model</i> is being developed, which defines ontology of indoor location. The model is complementary to 3D concepts like <i>CityGML</i> and <i>IndoorGML</i>. The goal of the model is to provide an exchange <i>GML</i>-based format for location needed for indoor routing and navigation. An elaborated user requirements analysis and investigation of state-of-the-art technology in expressing indoor location at home and abroad was completed to identify the manner humans specify location. The ultimate goal is to provide an ontology that will allow absolute and relative specification of location such as "in room 321", "on the second floor", as well as, "two meters from the second window", "12 steps from the door".
