Interoperability Public Working Group
READ-ONLY SITE MATERIALS: Historical voting TWiki site (2015-2020) ARCHIVED from https://collaborate.nist.gov/voting/bin/view/Voting
Interoperability Working Groups and Common Data Format
The Interoperability working groups are for the discussion and development of guidance for voting system interoperability, including common data format (CDF) modeling and schema development. The guidance will inform the development of requirements for the Election Assistance Commission (EAC) Voluntary Voting System Guidelines (VVSG). The main activity underway is the development of CDF specifications for voting device imports and exports. Another activity is assisting with interoperability-related requirements development for the next VVSG.
Many election officials view voting system interoperability as necessary core function for future voting technology. This working group has as its objective the development of guidance and CDFs that will result in voting system interoperability, bringing with it various advantages, including:
- Increased efficiency in election operations.
- Cost savings to election operations and to cost of system integration.
- Greater choice of voting equipment in the marketplace.
- More automated generation of EAC survey data.
- Reduced cost of testing and component certification.
- Greater transparency to election data.
Next VVSG Requirements Development
The working group has been assisting in the development of principles and guidelines and general interoperability requirements for the next VVSG.
The latest draft of the VVSG glossary is located here:
https://github.com/HiltonRoscoe/GlossaryMD/blob/master/vvsg_living_glossary.md
These definitions will in some cases need to be edited so as to be more clear, but they also need to be examined by election officials and others to ensure the definitions are accurate. If you have any changes or suggestions, please send email to john.wack [at] nist.gov (john[dot]wack[at]nist[dot]gov).
The latest drafts of requirements for the next VVSG are located here:
https://www.eac.gov/voting-equipment/voluntary-voting-system-guidelines/
CDF Specification Development
The CDF work is documented at
https://www.nist.gov/itl/voting/interoperability
Each CDF specification has its own GitHub repository (see What is GitHub) and, in most cases, web-based documentation. The repositories contain the UML models and XML/JSON schemas, in addition to a PDF of the CDF specification and other documentation. The following table contains links to the repositories and web-based documentation:
| CDF Name | GitHub Repository | Documentation |
|---|---|---|
| Cast Vote Records | usnistgov/CastVoteRecords |
pages.nist.gov/CastVoteRecords |
| Election Event Logging | usnistgov/ElectionEventLogging |
pages.nist.gov/ElectionEventLogging |
| Election Modeling | usnistgov/ElectionModeling |
pages.nist.gov/ElectionModeling |
| Election Results Reporting | usnistgov/ElectionResultsReporting |
pages.nist.gov/ElectionResultsReporting |
| Voter Records Interchange | usnistgov/VoterRecordsInterchange |
pages.nist.gov/VoterRecordsInterchange |
| Voting Methods Models | usnistgov/VotingMethods |
TBD |
Current Status and Meetings
The NIST Voting System Interoperability Working Group meets by telecon as needed. The interoperability working group meetings generally include overviews of current work and discussion of broader issues such as overall scope of the CDF work. In addition, the meetings also may focus on interoperability-related requirements for the next VVSG.
Membership in this group is open to all; please subscribe to the email list, following instructions at VVSG Working Group Lists page.
