Transparency is a key aspect of open science as well as of the CRC’s research program. The members of the CRC commit to the principles of the open science movement, and the objective of the Open Science Data Center (OSDC) is to facilitate this. Besides maintaining the information technology infrastructure of the CRC, its activities can be structured by four distinct fields. First, it collects and provides data to researchers. Second, it develops and maintains software tools for open science toolchains. Third, it develops educational materials and runs educational sessions. Fourth, it conducts predominantly methodological research on open science-related topics. All these activities are meant to promote open science for accounting researchers and the wider research community. The long-term vision of the OSDC is foster collaborative and inclusive (accounting) research by providing impactful, high quality, and freely licensed data, methodological research, and well-maintained software tools.
