Five Distributed Query Initatives (that we know of)

As of today, we know of five distributed query initiatives:

1) ONC use case
2) Barry Rhodes' experimentation with PostgreSQL
3) University of Utah's (NCPHI COE) use of DCQL (caBIG / Globus) component
4) OGSA-DAI (specifically, NCPHI lab's work with RODS & general federated query use case)
5) electronic Primary Care Research Network (ePCRN) at the University of Minnesota (lead by Dr. Peterson)
