A (very quick) word of warning to any software developer considering using the JSON/XML document translation software AtlasMap (https://www.atlasmap.io).
At least not until they decide to join the real world and fix a major shortcoming: see this (laughable) bug report:
In a nutshell the bug is you can’t update you mapping after it is created! Unf#cking believable!
Talk about missing critical functionality. Don’t let them waste your time, like they wasted mine.
