Hi Mat,

Thanks for the pointer, I didn't know this existed.

Scroll down to the very bottom of that page, to the reference to "RDF".
It suggests RDF will provide a replacement for PICS.

The Open Clip Art Library has been pushing hard for getting RDF support,
and in fact has gotten support for it added to Inkscape.  As well, we've
produced a Perl module, SVG::Metadata, which enables adding RDF to SVG
images.  Today, all of OCAL's SVG images are required to include RDF
XML embedded into each document, and in fact we reject any SVG images
that don't have it.

What we're needing right now is the keyword vocabulary to add to RDF to
enable filtering.
