The Digital Iconographic Atlas of Numismatics in Antiquity (D.I.A.N.A.) aims to perform an in-depth analysis of the coin iconography according to time and space through digital maps. The project has been designed with an eye toward the possibility of a future integration with other digital archives. The basic idea is to enable DIANA to analyze, besides ancient mints and coin iconographies, even other related data. An objective of DIANA is to link and integrate its datasets with others coming from different digital archives in order to improve a particular study aggregating different pieces of information to better understand the diachrony and the cultural context. In this paper, we analyze the main aspect involved for the integration of DIANA with other digital archives in a scenario of linked data.
