The DDI Registry enables you to obtain an agency ID from the DDI Alliance. Using this permanent identifier in your DDI instances allows you to specify the authoritative source of your data and metadata. The registry is connected with the global DNS system, allowing DDI URNs to be resolved using standard tools.
- Detailed registration instructions are provided covering required information and structure of the DDI Agency ID.
- The site can be used to search for information on existing Agency IDs or view a list of all registered Agency IDs.
The source code for the registry and several related tools is also available under an Open Source license from the web site. The DDI Registry is maintained by the DDI Alliance.
