Due to the large influence of the radiation of the parent star on the
planet atmosphere, a careful target selection as well as a deep
knowledge of their properties (as a way to estimate their fundamental
parameters) and environments is a critical issue for the Darwin
mission.  The compilation of all this information is a time-consuming
task that will need, most likely, to be repeated a number of times
until the final satellite configuration is decided.  Before the
Virtual Observatory, the data compilation from more than one service
was a very inefficient process done, most of the times, slowly and
painfully by hand.  The user needed to identify the services of
interest, then, submit the same query for each one the services and,
after gathering all the information, to tackle problems like unit
conversion, flux calibration and/or data format.  The Virtual
Observatory (http://www.ivoa.net) is an international project that
aims to solve this problem by the creation of a federation of
astronomical archives and services that, with the implementation of
new technologies and standards, provides an efficient access to the
astronomical data.  In the framework of the Spanish Virtual
Observatory (http://svo.laeff.inta.es) an application to get all the
relevant information of the potential Darwin candidates already
available in astronomical archives and catalogues is being developed.
The system is also prepared to include new observations performed
during the preparatory observational roadmap.  A preliminary version
of the tool is already available (at present only for internal use) at
http://sdc.laeff.inta.es/darwin.
