Hi Rick,

The W3C RDF validator graph might not be the easiest way to look at
the domain model and the data. BTW since you are familiar with graph
visualization engines you might recognize the visual tool that's used
here. It's based on Graphviz. There are a number of anonymous nodes
that make it more diffucult to read the graph. Your hand-drawn graph
obviously is much easier to read. Are you already familiar with
anonymous nodes in RDF?
