What is a trustworthy digital preservation repository or service? How do you know if your system is 'trustworthy?' The core value of an audit is the evaluation by an expert practitioner relative to accepted industry standards and practices and then the recommendations for improvement. Most organizations find the development of a "Capability Maturity Model" assessing their implementation against its goals as a very useful step in gaining value from the audit process.
The European Framework for Audit and Certification of Digital Repositories has proposed this (certification) framework. It will consist of a sequence of three levels, in increasing trustworthiness:
Granting of these certificates will allow repositories to show one of three symbols (to be agreed) on their web pages and other documentation, in addition to any other DSA, DIN or ISO certification marks.
