List of awesome Trusted Digital Repositories
"TDR" is a term used in the digital preservation field to refer to a digital repository that has undergone a formal auditing process. These audits are typically based on ISO 16363:2012 "Space data and information transfer systems -- Audit and certification of trustworthy digital repositories".
ISO 16363 is a standard for determining the trustworthiness and durability of the information that is stored in a digital repository.
It takes into account a number of technical, organizational, and economic factors to determine whether a given repository can be trusted to deal with long-term threats to the authenticity, usability, and discoverability of the digital information objects in its care.
