Requirements Database

Hey all,

I'm working on a project that involves testing of several system components. Each of the components would have several functional requirements. We're looking into getting some way of having a database of these requirements that has the following features:

• store requirements / manage changes / revisions
• categorise and group requirements / sort for printing
• maintain status of testing (passed / not run / failed etc)
• be web based so that it can be accessed from multiple locations
• Manage findings / print reports

Something like JIRA might suit, but we'd prefer to go the opensource route. Anyone have experience with an application that might suit?

Thanks
