Persistent Identifiers are quite tricky, as
discussed in Sect.
10.3.2
. It seems
worthwhile to make sure a number of
points are checked..
4.2.4.1.1 The repository shall have unique identifiers.
4.2.4.1.2 The repository shall assign and maintain persistent identifiers of the AIP
and its components so as to be unique within the context of the repository.
4.2.4.1.3 Documentation shall describe any processes used for changes to such
identifiers.
4.2.4.1.4 The repository shall be able to provide a complete list of all such identifiers
and do spot checks for duplications.
4.2.4.1.5 The system of identifiers shall be adequate to fit the repository's current and
foreseeable future requirements such as numbers of objects.
4.2.4.2 The repository shall have a system of reliable linking/resolution services in order to
find the uniquely identified object, regardless of its physical location.
Representation Information is key for
preservation.
4.2.5 The repository shall have access to necessary tools and resources to provide authoritative
Representation Information for all of the digital objects it contains.
There are a number of ways to obtain
enough Representation Information.
These sub-metrics about at least these
aspects of Representation Information.
4.2.5.1 The repository shall have tools or methods to identify the file type of all submitted
Data Objects.
4.2.5.2 The repository shall have tools or methods to determine what Representation
Information is necessary to make each Data Object understandable to the Designated
Community.
4.2.5.3 The repository shall have access to the requisite Representation Information.
4.2.5.4 The repository shall have tools or methods to ensure that the requisite Representation
Information is persistently associated with the relevant Data Objects.
