Goals of CDA
CDA: Goals
Give priority to delivery of patient care.
Allow cost-effective implementation across as wide a spectrum of systems as possible.
Support exchange of human-readable documents between users, including those with different levels of technical sophistication.
Promote longevity of all information encoded according to this architecture.
Enable a wide range of post-exchange processing applications.
Promote exchange that is independent of the underlying transfer or storage mechanism.
Prepare the design reasonably quickly.
Enable policy-makers to control their own information requirements without an extension to this specification.
