Quick note to say thanks for the interest in RDFViz, the GraphViz based
tool for laying out RDF graphs for display.

Thanks to the work of Stephen North and the other GraphViz folk,  RDFViz
can now generate simple SVG and VRML visualisations of RDF data graphs.
I didn't do much to take advantage of this for RDFViz except provide a
web-based wrapper for  the -TSVG and -TVRML command line flags :-)

When I'm happy with a version 1.0 of RDFViz I'll get a copy hosted on a
W3C box and bundle up the scripts. In the meantime I was hoping to set
people thinking about RDF, SVG, VRML... All of these can be represented in
XML (not sure about status of the VRML in XML work though). We can go
to SVG and VRML from XML/RDF data graphs (either using RDF 1.0 syntax,
other RDF-like syntaxes such as SOAP, or XSLT transformations. Question
is: can we go the other way, ie. extract the abstract structure from an
SVG or VRML diagram...? 

This is where Semantic Web screenscraping [1] meets Web Accessibility... 
Once everyone uses XML for everything, what more can we say about the
abstract structures that are common across our various uses of
XML? eg. Could an organisational chart in SVG or VRML be self-describing
enough to allow applications to extract the RDF model it represents?
