The library code is exercised in two different test suites. Within the approved GRDDL Test Cases, there is a section dedicated to the library.

This library was initially created by Jeremy Carroll, as part of the work of the GRDDL Working Group. The first two transforms were initially written by Dan Connolly and Dominique Hazaël-Massieux; and have been modified by Jeremy Carroll.
