Vici.org is a crowd-sourced map of ancient Rome that allows users to add markers, images, and line tracings to locations. The project aims to open up its database for others to contribute and access geographic data, taking inspiration from Wikipedia. As of mid-2014, the map has over 200 registered users but only 68 have contributed by adding markers, with most markers coming from a small number of top contributors. The project faces challenges in attracting more international contributors and developing community features to further engage users.
