The Center Digital Editions & Edition Analytics (University of Zurich), in collaboration with Research and Infrastructure Support (University of Basel), is pleased to announce the conference Open Up Digital Editions. In recent years, numerous innovative digital scholarly edition (DSE) projects have been implemented in Switzerland. The result is a growing scientific community. With the increasing number of digital editions and the continuous availability of new edition data, issues of use and re-use are increasingly coming to the fore. However, many questions remain open and unresolved: Do editions meet the research needs? Which standards should future projects adopt? How do digital editions remain accessible after the end of the project? How can edition projects be linked with each other? These questions are of great concern to researchers, infrastructure providers and knowledge management institutions. The conference will provide a framework to discuss current approaches with a focus on developments in Switzerland and in relation to the international landscape.
