The Free Software Foundation Directory of open source projects lists those that run under "free" systems, particularly GNU and GNU/Linux variants.
Every month we collect the available project-level metadata from the Free Software Foundation's directory, and load that into our database. We then parse through those html pages and extract interesting data elements. After parsing, we save each piece of data in our database also. We then provide this data back to researchers to do with as you wish.
