On 06.11.23 another DeepGreen consultation took place for our participating repositories. After a presentation of current developments in DeepGreen (publishing cooperation with Copernicus, optimization of metadata mapping, DeepGreen & Elsevier DEAL), we reviewed the recent Open Access Days 2023, which took place in Berlin in September. In reviewing the discussions at this conference, we discussed possible service extensions to DeepGreen, such as metadata delivery without full-text and retrieval of individual full-texts via DOI matching. We also discussed a poster on the extension of the EZB interface, which was also presented at the Open Access Days. As a result, we identified the integration of the ROR ID in the EZB metadata as a priority for DeepGreen, as this would greatly facilitate institutional attribution. Other topics discussed were the handling of duplicates and error messages in the SWORD interface in DSpace. All participating repositories are explicitly invited to participate in this recurring exchange format.
