Federated query using DCQL and credential delegation
Created: 2010-05-11 20:21:58
Last updated: 2010-11-05 21:06:29
CDS_Activity issues an EPR of the delegated credential. FQP uses this EPR to fetch the actual delegated credential from CDS and uses it to invoke multiple data services (the query activity) on behalf of the invoker.

Need to install Taverna 2 caGrid integration suite from http://www.mcs.anl.gov/~wtan/t2/ and get a cagrid Dorian account (see http://wiki.cagrid.org/display/caGrid13/Home)
