When you want to draw diagrams with circles and arrows. Fundamentally RDF is
a convention for saving a diagram as a document, or to a database. RDF
describes things and relations between things. You can take any RDF document
and flatten it into a single table that can be queried etc. Its the simplest
'infoset' you can imagine. It is _so_ simple it appears complicated.
