Hey guys,
I've released some preliminary code that integrates fully with OG (Drupal6) and provides analytics extension for each group.
At the moment you get out of the box a very minimal dashboard view and downloads report. A few points to note:
1. The architecture was built to be modular so that every module can extend or create it's own new reports.
2. It is based on Google's Chart API (the new one, not the old static image charts, and due to that it is also fully ajaxed or REST if so to say).
The project is in my sandbox, you can view some sample screenshots with minimal data here: http://drupal.org/sandbox/lirantal/1705198
More ideas, comments and general feedback are welcome!
Thanks,
Liran.
