Consolidated CDA R2.1 DSTU Update

The purpose of this project is to quickly develop an update to the existing Consolidated CDA DSTU 2.0 specification to support backwards compatibility with C-CDA 1.1. The requirements are that an existing EHR certified under 2014 or 2015 ONC Standards and Certification criteria be able to correctly interpret the content of a C-CDA 2.1 without requiring change to the product presuming that it has followed good development practices in interpretation of the CDA Standards and C-CDA 1.1 specifications.

The project builds on the work of the Dual-CDA Compatible Task Force to address the issues it found between C-CDA Release 1.1 and C-CDA Release 2.0.
