Election Results Common Data Format Specification



John P. Wack, Kim Brace, Samuel Dana, Herb Deutsch, John Dziurlaj, Ian Piper, Don Rehill, Richard M. Rivello, Sarah Whitt


This publication describes an election results common data format specification for pre-election setup information and post-election results reporting. It contains a UML model of the election data and an XML format derived from the UML model. It also contains background information regarding how geo-political geography is structured and used in the model and schema. The XML format is comprehensive and at the same time very flexible, able to accommodate election scenarios used throughout the U.S. It is part of a series of planned common data format specifications for voting equipment.
