Concordia was a joint project of King's College London and the Institute for the Study of the Ancient World at New York University that ran from April 2008 to March 2010. It was funded by paired grants from the US National Endowment for the Humanities and the UK Joint Information Systems Council. The project pursued two complementary goals: dissemination of key epigraphical, papyrological, and geographic resources for Greek and Roman culture in North Africa; and piloting of reusable, standard techniques for web-based cyberinfrastructure. Work on North African content has continued subsequent to the end of the grant. Resulting resources may be seen in a number of resources, including: Inscriptions of Greek Cyrenaica, Inscriptions of Libya, Inscriptions of Roman Cyrenaica, Inscriptions of Roman Tripolitania, Papyri.info, and Pleiades. In terms of "cyberinfrastructure", the project focused on mechanisms for communicating object-level relationships among separate projects and datasets using the Atom feed format. In this regard, Concordia may be seen as a predecessor of many digital classics projects that are now experimenting with Linked open data in various formats, including: the Linked Ancient World Data Institute, Pelagios, and Standards for Networking Ancient Prosopographies. One key outcome of the project was the production of a series of "Barrington Atlas IDs", which set the stage for cross-project linking of ancient geography content.
