Justin Richer of Bespoke Engineering proposed the XYZ concept and project based on experience and conversations with a wide variety of industry experts. Concepts incorporated into XYZ come from many different projects in the internet security and identity space, and have been referenced where applicable. The protocol aspect of XYZ has been subsumed by GNAP, and XYZ is now most properly used to refer to several specific implementations of GNAP. The examples on these pages and discussion are therefore now primarily about GNAP and not specific to the XYZ implementations.
