This document provides an agenda for an Open Data Census workshop at the Open Knowledge Conference in Geneva in 2013. The workshop aims to introduce participants to the Open Data Census and get input on how to improve the tool. The agenda includes an introduction to the Census and discussions about visions for creating a better tool. It then splits participants into two groups - one to continue discussions, and one to explore open data and submit findings to the Census. The workshop concludes with a wrap-up discussion.
