Role of the TC
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.
