FRIDA (FRiendly IDentificAtion) is a new software application for producing multi-authored interactive identification keys, which can be published on the Web, stored on optical devices, and used on mobile devices as PDAs and Smartphones, both on-line or in stand-alone mode. FRIDA is based on a double-level architecture, which grants to the authors that are involved in multi-authored projects a high degree of independence while working on their data, and several instruments to control and modify the final result of the elaboration of the keys. FRIDA can produce keys from the data by one author only, as well as keys from data by several different authors, merged together into new and original entities. In this paper we discuss the most interesting features of the FRIDA package, and detail the process of generation of an identification key.
