This interface contains some methods that create connections between the content and the RDF metadata of an ODF document. The main idea is to make querying and manipulating the data in the metadata manifest easier.

Note that this interface inherits from XURI: the base URI of the document is the string value of the RDF node. This is so that you can easily make RDF statements about the document.
