The ANGLES project is an experiment in digital humanities tool development. The project proposes a new solution to the adoption gap that has developed between scholars with digital materials and technical developers designing the applications scholars are using in their research. The aim of ANGLES is to go beyond the exploratory, hermeneutic coding of a small group of scholars and to build on the success of the "barnraising" small institute model by combining a model of intensive code development (the “code sprint”) with participatory design exercises, testing and feedback from domain experts gathered at internationallyrecognized disciplinary conferences. This approach is intended to address the need of a new software product to generate users, provide better technical development by having potential users to explore code as it is being created, and allow the scholarly and developer communities to more clearly elucidate their intellectual, methodological, and technological needs in a structured collaboration process. As a pilot for this “community roadshow” approach to tool development in the digital humanities, the ANGLES Project will develop a webbased editor for working with XML markup through engagement with the large and active community of scholars, teachers and developers who work with the TEI.
