A VVSG-derived model of election data



David W. Flater


An effort to define a common data format for voting systems should begin with a data model that specifies the relevant concepts. To accelerate adoption and minimize conflicts, such a model should define the smallest set of concepts needed by the desired functionality. We present a small data model that suffices to cover the election definition and vote data reporting requirements of VVSG 2.0, with the exception of reporting for ranked order contests. This model may be used as the basis for continued work, in whole or in part, without restriction.
