If you want to expose RDF data for Piggy Bank to collect, add one or more links to RDF/XML or RDF/N3 files in the <head> element of your web page like this:

     <link rel="alternate" type="application/n3" title="Screen scrapers' information" 
     <link rel="alternate" type="application/rdf+xml" title="My contact information" 

Note that the URLs to your RDF files must be absolute.
