The details are in the TOU but in a nutshell:
- You must put a visual indication that data originates on the Ohloh site, near where you use Ohloh content.
- You must link back to the original source of the data on Ohloh in such a way that the link is visible and can be followed both by humans and by search engines.
There are a few other detailed requirements but those are the main ones.
