What Is MRV file format?

MRV (ChemAxon Marvin Document) is an XML based chemical structure file format used by Marvin, developed by ChemAxon.

MRV can be used to store molecule structures and chemical reactions.

Example of a MRV file for a reaction:

<?xml version='1.0' encoding='UTF-8'?>
<cml xmlns="http://www.chemaxon.com" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
