Lyubov agreed to the idea of a JSON interpreter, to help caDSR and others to move off of RMI.  She wants it to be generally useful, not tailored only to caDSR.

Lyubov met with Brent Coffey last week. They rejected all suggestions saying their system is "too fragile" and that migrating to CTS2 or EVSRestAPI is too risky.  They are exploring costs for continuing Java 7 support.

For history's sake, here is some of the important documents

• CTRP - what is it NCI Clinical Trials Reporting Program (CTRP) User Guides
• Source code for the class that calls lexevs64
• Their diagram of key return values
• My attempt at a mapping to CTS2
• Sample query
