The Asiago Database on Photometric Systems (ADPS) and the design of the GAIA photometric system

The Asiago Database on Photometric Systems (ADPS) is a compilation of basic information and reference data on 201 photometric systems (both ground-based and space-born), available in book format (Moro and Munari, 2000) and electronically (http://ulisse.pd.astro.it/ADPS). It is a relevant source of information to address the legacy of existing photometric systems to the one being designed for the GAIA mission. Its use in such a context and the planned developments are briefly discussed.
