A specially tailored database supports the research of SPECTRUM. As the research focuses on monumental, architectural reproductions as well as on pictorial, textual, cartographical, and sculptural representations of Jerusalem, the database incorporates different types of research material pertaining to different media, enabling the organization of knowledge in a way that reveals parallels and relationships between the different types of representations on a geohistorical scale. For the moment, the database is open to the SPECTRUM research team, and the results of the research are being presented in publications and conferences.
