Statements created using semantic wiki syntax will be stored in the context of the active wiki page. Internally, these statements will be placed in an RDF store. If you want to easily access their RDF-representation directly, you can do so by clicking the 'View RDF' link at the bottom of a wiki page. This will bring up a new page displaying all statements in RDF/XML syntax. This makes it particularly easy to reuse and exchange your semantic data in a standard way.
