Dear Colleagues,
We are pleased to announce that Version 1.0 of DDI Cross-Domain Integration (DDI-CDI) has now been officially published!
DDI-CDI extends traditional DDI metadata to describe data beyond the social, behavioral, and economic (SBE) domains, addressing the need for broader capabilities. It supports descriptions of event and sensor data ("long" data), key-value data (often associated with "big" data and no-SQL data), and multi-dimensional data. By integrating these with traditional "wide" (or "rectangular") DDI data descriptions, DDI-CDI enables the management and production of integrated data sets from diverse sources.
Additionally, DDI-CDI facilitates the documentation of generic processes, allowing for clear descriptions of the steps involved in data integration. To ensure compatibility with varying technologies and standards used across domains, DDI-CDI is designed to interoperate with a wide range of web standards, supporting both XML- and RDF-based syntax representations.

The publication of DDI-CDI Version 1.0 would not have been possible without the DDI-CDI Working Group, led by Arofan Gregory (Chair), and the Technical Committee, whose efforts ensured a rigorous and collaborative development process. This work reflects contributions from across the DDI community and builds on the foundation laid by the earlier DDI Moving Forward (DDI 4) effort.
We extend our sincere gratitude to everyone involved in this achievement and to the DDI Alliance members whose support made this development possible.
Sincerely,
Jared Lyle
Executive Director, DDI Alliance
