Although we didn't have time to implement this example before the 
C-SHALS meeting, as we discussed at our BioRDF call today, we will 
implement this example and include it in the BMC Bioinformatics paper 
(on query federation) that we're working on. Eric has updated his 
FeDeRate code so that performance has been improved significantly.

The receptor tables (in csv format) are listed at:


Eric, please use the "Class C" table and load it in your relational 
database. Also, Matthias and Rob will help in this implementation effort.
