Templates have been significantly improved in Firefox 3. The key improvement allows the use of custom query processors to handle other types of datasources besides RDF. A new query syntax makes this possible. Built-in support for SQL (mozStorage) and XML datasources is also provided. A full description of the new features available for templates is available.
