DDI-Lifecycle

DDI-Lifecycle Development History

The current DDI-Lifecycle specification, DDI 3.1 reflects (1) the correction of bugs identified by implementers using DDI 3.0, and (2) the resolution of the final URN structure to ensure persistent URNs for all identified elements. Note that DDI 3.1 is not backward compatible with DDI 3.0. A change file in the download package identifies all changes, including which changes were backward compatible and the steps to take to move  DDI 3.0 instances to DDI 3.1.

On May 25, 2009, the DDI Alliance Expert Committee voted to publish the DDI 3.1 specification following minor corrections and resolution of the URN structure. DDI 3.0 was published on October 18, 2009.

The development of DDI-Lifecycle 3.1 draws on earlier DDI versions and work of the committees and individuals who developed them as well as the collective ideas, needs, and work of the Expert Committee of the DDI Alliance. Major contributions to DDI-L 3.1 were made by many individuals and organizations.

DDI Lifecycle 3.0 to 3.1 Mapping

The specification file contains a change document which lists all changes, whether they are backward compatible, and the changes required to move from 3.0 to 3.1.
