search tool: plea for help

I would like to start marking up SVG with RDF on our site with 
immediate effect.

However I'd also like a public online search form (tool) to check pages 
in a directory for rdf search terms.
and probably use it to update a keyword directory as an alternative.

does anyone know of such a tool? in development?

OK it seems great to distribute the info, but unless the search tool is 
also distributed something seems kind of missing.
or perhaps its just me.

thanks

ps: I'd appreciate a couple of hours with someone to get this 
started.....
