Such opening of the black box of institutions is possible using mixed methods to describe institutions in detail over time and space, which serves as an archaeology of institutions. The archaeology of institutions can be understood as "an approach by which the change of institutions is meticulously recorded, interpreted and studied through the collection of data from every possible source, regardless of whether that is socio-economic, historical, ethno-anthropological, geographical, psychological or legal-political." An example of this, is the history of China's titling and housing ownership.
