Google HCLS Whistle Data Transformation Language
Summary
This defines a syntax designed to express mappings of data from one structure to
another.
This syntax is transpiled into a configuration file for the
Data Harmonization Mapping Engine
which can then execute the mappings.
The engine accepts data in JSON format and outputs it in JSON format.
For information on the syntax, look at the included documents in the docs
folder.
