Hubert,

Welcome to our discussion forum. Please also go to our wiki page and create
an account there (see the links page at the OVC site).

When I made a first draft of what we wanted to demonstrate with our demo
software, I included county-level tabulation. That's where the different
scoring methods come into play. We had to scale back a bit on the demo
software. As it was, we had four applications running:

1) GUI (touchscreen or mouse) ballot printing system (pollsite, and also a
web-based simulation of the pollsite system)
2) Reading impaired interface ballot printing system
3) Ballot verification station (reads barcode and vocalizes choices)
4) Ballot Reconciliation System (or "procedure")

You might want to have a look at this document to see how the ballot
reconciliation works:

This paper describes a little more about the data format (thanks David
Mertz)

There are also a couple papers the OVC team produced found here:

Arthur has presented this paper at a conference in D.C. (maybe he's there
right now)
