Become a Member of the Alliance

The DDI Alliance is a self-sustaining membership organization supporting the creation and development of the DDI specification as an international metadata standard for documenting social science data. The DDI Alliance welcomes the participation of diverse organizations in for-profit or not-for-profit educational, commercial, or governmental organizations that want to have a voice in the decision-making process for the standard.

Subscribe to DDI Users Listserv

The purpose of this list is to allow people who are interested in the development and implementation of the DDI specification to communicate with each other and with the committee that is guiding the development of the specification.

Join a DDI Working Group

Working Groups advise the Executive Board or the Scientific Board on relevant topics and activities related to the operation, development and future of the Alliance and its specifications and semantic products. Anyone affiliated with a member organization with relevant knowledge and expertise on the given subject may apply to join a working group. Each group must have a designated leader for managing the work and reporting to its authorizing body. 

DDI Collaboration Wiki

This wiki is home to current documentation for the Technical Committee and a few working groups, as well as the DDI Moving Forward Project, an initiative to develop a model-based DDI specification in the Lifecycle line.
