The FreeGIS.net Project approaches the recording, the analysis and the return of geographic information through the use of open data formats and Free Open Source Software. It is an in-depth analysis of the Interreg Italy-Switzerland project called CoCOS and it is consolidated through the Software Centre South Tyrol. The aims of Free GIS are: defining the necessary characteristics for developing the multilingual capabilities of the GIS software; identifiying the details of a Reference Implementation composed exclusively by Free Software components; determining a FreeGIS Data Licence. All project steps include a status quo analysis and lead to the publication of guidelines especially dealing with the Public Administration, in order to improve the GIS data with the help of the European Directive INSPIRE.
