In trying to learn more about XBRL, an important first step is to find software, and I don’t want to pay for it. Open Source is even better, in case I want to build some application around it. I’ve written up my research experience with each free package I heard about, roughly in most promising to least promising order. For sample input, most of my testing used XBRL filings to the SEC by large multinational corporations specializing in carbonated brown sugar water.
