The FIDELIS project aims to establish a European Network of Trustworthy Digital Repositories (TDRs) that will support their development and growth, foster harmonisation and interoperability, and strengthen relevant skills through training and support. For this project to successfully achieve its goals, it was deemed essential to gather input from the community on their current practices, challenges, and needs. The outputs of this survey will be used to shape the activities of the project in the next years, and subsequently help shape the FIDELIS Network as it is designed and implemented. This activity was a collaborative effort across the project, with each part of the project focusing on their own sections of interest. This one report presents the full analysis of the survey results, covering the two associated Milestones (M11 survey analysis ready and M19 Analysis of survey results with regards to support and training) and additional analyses on other relevant topics.
