The simplified diagram has two disconnected graphs.
The first graph connects the node http://www.bar.com/some.doc with the string value node containing "John Smith" via an arc labeled DC:Creator. This entire graph is identified as BAGID Statement_001.
The second graph has three nodes. The first node is identified as Statement_001. From this node, two arcs labeled DS:CreatedOn and DS:CreatedBy respectively point to nodes containing the string values "1998-02-06T14:00Z" and "Jane Cooper".
