By 2016, we realised a new generation of data repository was needed to accompany the ELN. The DataCite metadata schema 12 was constantly being extended and we needed to match the new capability this offered with the functionality of the repositorythe existing Dspace technology used for SPECTRa was not then considered as easy to adapt for this purpose. Further persistent identifiers such as ORCID 18 had now been introduced and we wanted to make their use mandatory with the repository. Finally, the Dspace technology itself was considered non-trivial to upgrade and we needed a more lightweight tool.
