provides a widely applicable glossary of terms and the unified definitions of functions, process
and information model. OAIS has been proved to provide a good foundation for certification of
trustworthiness in system level.
Establishment of professional standards, including ISO 16363 and DIN 31644, provides a
relatively comprehensive certification indicator framework for preservation activities. They focus
on assessing the overall project, but there is a limitation that they only audit the current state of
projects. A three layers trustworthiness certification frame of EU, inheriting the existing research
results (including DSA, ISO 16363 and DIN 31644), is not only more reasonable and feasible
for preservation practices, but also more conducive to gradual consummation of the preservation
system. And some existing theories and standards which are adopted in other areas will provide
additional verifications about trustworthiness from multiple perspectives.
The basic frameworks of the current three certification standards are coherent, and are composed
by three parts which are organization, object management and infrastructure. The organization
and infrastructure are the environments of executing the digital object management functions. The
organization includes strategic policy, staff, funding, law, responsibility mechanism, and is the
management environment to ensure preservation system works well. The infrastructure includes
completeness, safety and risk management of technical facilities, and is the physical environment
to ensure preservation system works well. And digital object management directly corresponds to
the specific process and functions of preservation system. Based on OAIS function modules, the
certification indicators of each module are classified into three groups: the first group is the indicators for
specification and documentation; the second group is the indicators for process and technical methods;
the third group is the indicators for records or logs (providing proof of reliability, credibility of process).
This paper provides a roadmap of development of certification research (1994-2014),
summarizes a primary elements framework of certification, and puts forward a series of questions
needed to be considered and discussed further in practices. All of these would provide references to
the practice of certification of trustworthiness. Based on literature analysis only, this research lacks
comparing and verifying the availability of existing standards in practices.
