The Data Bank is structured like a series of interrelated bases: Epigraphy, Numismatics, Onomastics, Lexicon and Bibliography. Furthermore, it has two supplementary tools which are linked to the remaining bases: the MapServer application, which generates distribution maps of locations which meet a certain search pattern, and a search engine which generates Graphics.
The Data Bank is continuously updated, which allows for the inclusion of new material, whether new inscriptions or any other kind of material, as well as reinterpretations of old data. At present, only part of the overall content is open to the public, specifically, the Palaeohispanic inscriptions of the Narbonensis and Celtiberian regions, and the Numismatics Base. As the team completes its publication of texts from other epigraphic regions or onomastic bases, so these will be made available to the public.
The Hesperia data bank was designed and constructed by E. Orduña and based on the LAMP platform, that is, the Linux operating system, the Apache web server, the MySQL database engine and the PHP programming language; all of them significant representatives of free open-source software, as is MapServer, developed by the University of Minnesota and used to generate maps. The data bank is accessible through the Internet by using any navigator, although it has been optimised for Windows Vista and the FireFox navigator.
