RIS Synergy seeks to optimise administrative support for research projects by once only data entry and raise the international visibility of Austrian research. For this purpose, RIS Synergy first analysed the research information landscapes of all project partners, and discussed common denominators as well as differences. Based on this, the team defined use cases for future interfaces to describe the exchange of data between the CRIS of funding organisations and universities: exchange of funding programmes, project data, project output, financial data, organisational data. This poster presents the RIS Synergy use cases that will be implemented during the project duration, as well as further use case extensions.
