Voting System Interoperability Working Group

NIST-EAC Public Working Groups
Interoperability Working Group 

This working group is for the discussion and development of guidance for voting system interoperability, including common data format modeling and schema development. The guidance will inform the development of requirements for the Election Assistance Commission (EAC) Voluntary Voting System Guidelines (VVSG).
