Epigraphical data's polyvalence prompts multifaceted epigraphical research methods. Other than detailed annotations concerning the words, phrases, and narrative forms of epigraphical data, historical concepts and knowledge are necessary apparatuses to conduct epigraphical interpretation. The concept of epigraphical coordination differentiates epigraphical data according to specific coordinates, namely: (1) the space wherein the data was formed; (2) the time whence created; (3) the information within the data itself; and, unique to Chinese epigraphy, (4) annotation of epigraphical data. Epigraphic research must position epigraphical data according to the coordinates of time and space in order to discover qualifiable interrelations of epigraphic data. The voluminous corpus of Chinese epigraphic data would only be manageable under clear and systematic processing such as the coordination concept. Not only would the coordination concept systematically present the annotative value of individual epigraphic data, but it could also establish close affinity between epigraphy and historical study.
