Work with RDF Facts

Make Firefox act like a small database server that is smart about RDF data.

The W3C’s Resource Description Framework (RDF) standard is one of the more complex XML standards. RDF is an application of XML, but it makes little use of the XML tag hierarchy. Instead, it turns any specified tags into facts. Facts are stored in memory separate from the DOM tree of the RDF content. This hack shows how to use facts. Firefox has both scripting and direct XML support for facts.

What is Firefox RDF good for? It’s a very general mechanism for managing any kind of data, whether that data fits in an XML hierarchy or not. The output of an SQL query is an obvious example.
