RDF Inspector

If you're looking for a developer tool to help you debug and analyze RDF, then look no further than RDF Inspector. This Firefox extension is designed to do for RDF what DOM Inspector did for HTML and XUL development. Its goal is to provide developers with visibility into the contents of an RDF datasource, allowing you to watch changes in real-time and supply multiple visualization methods for observing metadata.

With RDF Inspector, you have the ability to inspect and manage the contents of an RDF datasource on your own. Some key features include the ability to open multiple RDF datasources simultaneously, ability to open both files and XPCOM-registered datasources, integration with DOM Inspector, support for shortening resource names using RDF Namespaces (with a namespace editor), parent/child visualization of composite datasources, and the ability to save datasources to a file.

Overall, RDF Inspector is a useful tool for developers who are working with RDF and need a way to debug and analyze their code. It's easy to use and provides a lot of valuable information that can help make XUL template and other sorts of RDF issues easier to deal with. The only requirement to use it is to have Firefox 0.9+ - 1.0+.
