Spending my time at work reading CIDX (Chemical eStandards) 1363 pages of it. I believe in practical solutions, I am not sure if this (1363 pages) can be practical, who will have nerves to go thru it and adhere to the standards? I like one particular quote "It has been determined that ChemXML 2.0 will not be backward compatible... As of Q400, ChemXML 1.0 was not in production use by any chemical company." This tells it all.
