The CoreTrustSeal (CTS) is an accepted trustworthy digital Repository certification process for both, research data management and digital preservation communities alike. But does it build on concepts known and understood by both of these communities? We take an in-depth look at the CTS requirement Ro-Background Information/Context, in which the applicants are asked to define their Repository Type, Designated Community and Level of Curation Performed. By extracting information from the publicly available assessment reports and crosschecking these against available supporting information, we relect on CTS from three viewpoints: the process, the institutional, and the community view. We distill concrete recommendations, which will be fed back to the CTS Board as part of the 2019 public call for review.
