In November, Camille Villa, Research IT's Digital Humanities Assistant, represented the DiRT Directory at a workshop on User Interface and Software Sustainability in the humanities and social sciences, hosted by the Center for e-Research (CeRch) at the Department of Digital Humanities at King's College London. Workshop participants included developers and project managers from a variety of European cyberinfrastructure projects designed to support digital research in the humanities and social sciences. The discussion was framed and facilitated by project team members from the Tools E-Registry for E-Social science, Arts and Humanities (TERESAH), which is currently under development. The DiRT directory, a long-running tool registry driven by a community of volunteers and powered by open source software, serves as an excellent case study in project sustainability. Camille also provided updates on DiRT development work currently being conducted between members of Research IT and a team at the Graduate Center of the City University of New York, under the auspices of the Andrew W. Mellon Foundation. See the Digital Humanities at Berkeley blog for more.
