Technical Committee


Upcoming Agenda Items



Production Framework: Information on the production framework for each DDI product.

DDI Modeling Guidelines

The Technical Committee is in the process of defining guidelines that would address modeling issues across the range of DDI versions where possible. These reflect changes in the production process, use of multiple binding options, and the varied use of DDI content. While individual versions  are not required to follow these guidelines, variance from them should be noted and explained. Guidelines are found HERE and are available for comment.
