Those interested in "semantic web" query tools should also check out our
SHOE Search tool. Many people find this tool easier to use than the PIQ,
although the range of possible queries is a little more restricted. SHOE
Search is the centerpiece of Semantic Search, the SHOE Search engine,
which was made available earlier this month.

Domain specific query tools are also possible. We have created one such
tool to assist risk assessment of product contamination for the FDA.
It's called the TSE Path Anaylzer.

It would be fairly easy to create similar tools for RDF.
