Hi Brad. It's a cool idea, but I've found a bug on this URL ^^: "http://www.fedoratracker.org/tracker.py?mode=listRepoPkgs&repo.repo_id=49". I see there a line with "Content-Type: text/html". Sometimes it is on top and sometimes on bottom. I used the IE6 to view the page. It's maybe a wrong http-header or something similar. But again, I think your approach is a good start to realize such a database. And I don't think that a explicit GUI is needed. A Web browser already brings you a GUI or not? Maybe some support could be added in tools that are involved in installing the packages. My fantasy: You can directly search for packages in the repositories and download and install it in a go. Perhaps some other developer-teams are willing to do this in their projects. Greets
