In 2006 the Portuguese National Archives (Directorate General of the Portuguese Archives) engaged in the development of an OAIS compatible digital repository system for long-term preservation of digital material. Simultaneously, at the University of Minho a project called CRiB was being devised which aimed at the development of a wholesome set of services to aid digital preservation. Among those services were format converters, quality-assessment tools, preservation planning and automatic metadata production for retaining representations’ authenticity. This paper provides a detailed description of both projects and discusses how these may be integrated into a complete digital preservation solution based on currently available archiving and preservation standards, e.g. OAIS, EAD, PREMIS, METS and ANSI/NISO Z39.87.

This whitepaper describes the integrated technologies produced in SCAPE and the results of its assessment against the ISO 16363 – a framework for Audit and Certification of Trustworthy Digital Repositories. The work aims to demonstrate that a preservation ecosystem composed of building blocks as the ones developed in SCAPE is able to comply with most of the system-related requirements of the ISO 16363. The SCAPE Preservation Environment (SPE) is composed of a repository system, an execution environment, planning & watch services, preservation control policies, and best practice guidelines and reports. From a total of 108 metrics included in the ISO 16363, the SPE fully supports 69 of them. 31 metrics were considered to be “out of scope” as they refer to organisational issues that cannot be solved by technology alone nor can they be analysed outside the framework of a breathing organisation, leaving 2 metrics to be considered “partially supported” and 6 metrics to be considered “not supported”. This gives an overall compliancy level of roughly 90% (if the organisational oriented metrics are not taken into account). Even though we consider this to be an excellent result, proving and giving guidelines on how it would be possible to have a system compliant with most of the metrics included in ISO 16363...
