Local Benchmarks of Infrared Galaxy Evolution : the SWIRE-SDSS Database, Far-Infrared Local Luminosity Functions & Virtual Observatory Tools

We describe the construction and the properties of the SWIRE-SDSS database, a preliminary derivation of the Far-Infrared Local Luminosity Functions at 24/70/160 micron based on such a database and ways in which VO tools will allow to refine and extend such work.
