NIST Support for IEEE VSSC 1622 - Voting Systems Electronic Data Interchange Current Project Status

As part of its voting program, NIST is providing support to the IEEE VSSC, with the goal of creating an XML-based common data format (CDF) for election systems. A CDF will facilitate interoperability among voting devices and certain types of automated testing. Election officials desire that interoperability of data will increase choice of voting equipment, will make possible component certification, and will significantly ease current difficulties in interfacing voting devices to external entities such as voter registration databases and reporting outlets. Manufacturers competing in an international business environment desire a CDF that works in international environments as well as the U.S. The scope of the work includes:

  • Exports of election management system databases including for election results
  • Voter registration data and precinct information processed by electronic pollbooks
  • Candidate and ballot definition information
  • Voted ballot information and tabulations
  • Device logs
  • Other information that may be produced by election management systems

The IEEE VSSC website is located at:

NIST is providing support to IEEE in the form of committee and working group management (NIST chairs the VSSC) and with NIST-developed technical material including UML election data models and XML schema development. For the IEEE 1622.2 working group for election results reporting, NIST is contributing the following material:

  • Election management system export including election results reporting UML model - version 43, June 9, 2015 (MagicDraw) (xml) (png)
  • XML schema generated from UML model - version 43, June 22, 2015 (xsd)
  • XML schema generated from UML model - version 43, June 22, 2015 (pdf)
  • Example files of U.S. state election results reporting data:
