Technical Committee
The purpose of the Technical Committee is to model, render, maintain, and update the DDI specifications to meet community needs and align with Alliance strategic goals. The TC receives input from substantive working groups of the Scientific Board, DDI users and developers, and other interested parties. This includes the development of conceptual models, implementation of models in various technical forms, monitoring the metadata landscape and related developments, and initiate and plan possible future directions for the standard.

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.
