How to consume data about drupal contributed modules?

Question

Is there a feed or feeds that expose data about all drupal contributed modules? I want to consume drupal.org data about modules in a certain category e.g. https://drupal.org/project/modules?f[0]=im_vid_3%3A59

I would love to get the catagories information e.g "Categories: Actively maintained, Under active development, Administration, Modules, Developer, Site Navigation"

I've seen http://drupal.org/node/63589, but the "Compatible with Drupal core 7.x" (http://drupal.org/taxonomy/term/103/0/feed) only lists about 72 ftp urls when I load it in a web browser. That is not all of the D7 modules...

I also looked at the About page on http://drupalmodules.com for clues about how they get the data, but didn't find anything useful.

Thanks for any pointers!
