Spec+Transition+Plan

=Versioning and Transition Plan (Work in Progress)=

Once the need for a chance to an Nationwide Health Information Network web service has been identified and a solution developed and approved...
 * An updated version of the specification will be published (e.g. Query for Documents 2.1)
 * During the transition phase, there will be two approved Production versions (e.g QfD 2.0 AND 2.1)
 * Depending on the nature of the change, the transition period may be up to 6 months or more, at the decision of the Nationwide Health Information Network CC.
 * Existing implementers must continue to support QfD 2.0
 * New Implementers have the option of supporting 2.0 or 2.1 or both. Decisions to support one instead of both will lead to varying risks of non interoperability.
 * The two versions will be held in discrete entries in the UDDI
 * At the end of the transition period, the initial version will be deprecated and entries removed from the UDDI registry

The scenario above applies both web services as well as foundation specifications. The consequences to changes in the latter type will impact every web service specification.

Changes to Foundations and Web Services will also impact Profile specifications.
