Just in case you never heard about OFX before V1 was an attempt to create a dedicated SGML for banking and ignoring XML. Details. It evolved to XML but not for M$ MONEY. Today we would use JSON for similar tasks.
I work as an Integration Engineer for United States Department of Veterans Affairs (VA). I work on a Health Connect production which processes many RecordMap files. I do not fully understand RecordMaps and I wanted to develop an application for the Interoperability contest where I could learn more about working with RecordMaps. I browsed InterSystems documentation for inspiration on how to start. I was happy to find CSV Record Wizard.
