The main obstacle for any research on the imperial properties is our current fragmentary knowledge of the sources due to the serious deficit of dedicated studies in the last century. In order to solve this problem in the best possible way, the first objective of PATRIMONIVM is the creation of the Atlas patrimonii, a relational database where all relevant evidence for the study of the imperial properties will be stored.

The database will feature four main tables, containing respectively records for textual sources (literary, papyrological and epigraphic), places (with geolocalization), people (from peasants to procurators and freedmen in general), and bibliographic references. The records of the different tables will be linked and cross-searchable according to a number of criteria. This powerful and versatile tool will finally allow us to manage all the pieces of relevant information scattered over a massive number of publications. The database will not simply contain raw data: translations, historical commentaries and bibliographic references will be provided for every textual source, while the descriptions attached to the different geographical entities will include topographic and archaeological informations. The prosopography will include all attested imperial slaves and freedmen as well as all persons working in connection with the imperial properties (administrations, tenants, contractors etc.).

The database will make use of EpiDoc, SNAP and of other XML-based open frameworks to digitally present the texts and handle a large amount of prosopographical data, textual annotations, citations, bibliographic references and geodata. This will allow for an unprecedented degree of interoperability with other online repositories. The inclusion of geodata will permit innovative ways of visualizing the geographic distribution of properties and people as well as mapping economic connections and human mobility in connection with the patrimonium Caesaris.

The database will be put online by the end of 2019. This will allow the researchers taking part to the planned series of workshops to take advantage of this tool. The database will be completed for the end of the fifth year and updated with newly published data even after the conclusion of the project. It will stand as a lasting result of PATRIMONIVM.
