I think today it makes sense to make all ODB dump in the JSON format - in my experience it is much 
easier to work with JSON data compared to XML data.

To write the ODB dump file in JSON format, set "/logger/ODB Dump File" to "run%05d.json".

In the midas data files, the ODB dump made into the begin-of-run and end-of-run events is presently 
unconditionally done in XML format.

Perhaps the data file dump should match the format of the odb dump file (both XML or both JSON or 
both ODB).

But at the moment our standard analyzer ROOTANA does not have the code to process JSON ODB 
dumps, so I am hesitant to make this change today, Maybe tomorrow when there is a VirtualODB 
JsonOdb class in ROOTANA. The requires JSON parser is already part of MIDAS (mjson.h/mjson.cxx).

K.O.
