Recovering Data from View

GRDDL'ing the target graphical format file would produce some of the RDF that went into the visualization.

http://www.w3.org/TR/grddl-primer/#spreadsheets-section shows to use the following markup so that GRDDL agents can trigger and extract the RDF:

<BLAH
  xmlns:grddl="http://www.w3.org/2003/g/data-view#"
  grddl:transformation="https://raw.github.com/timrdf/vsr/master/src/xsl/grddl/graffle.xsl"

Applying grddl/graffle.xsl produces a Turtle description of the graphical elements in an OmniGraffle file. In the sample below we see that a Rectangle with the label http://danbri.org/foaf.rdf#danbri is depicting http://danbri.org/foaf.rdf#danbri (the flesh and blood walking around).

<1049>
   a <ShapedGraphic>;
   a <Rectangle>;
