This publication is a specification for a common data format (CDF) for pre-election setup information and election night and post-election results reporting. The format is comprehensive and detailed in its coverage of election results-related data and at the same time very flexible, able to accommodate election scenarios used throughout the United States. This publication contains a UML (Unified Modeling Language) model, an XML (eXtensible Markup Language) schema, usage information and guidance, and background information.
The NIST SP 1500-100 specification, UML model, XML schema, and other files are available at:
