16.2.5 Data Management
The DATA MANAGEMENT functional entity in OAIS is the
entity that contains
the services and functions for populating, maintaining, and accessing a wide
variety of information. Some examples of this information are catalogs and
inventories on what may be retrieved from Archival Storage, processing algo-
rithms that may be run on retrieved data, Consumer access statistics, Consumer
billing, Event Based Orders, security controls, and OAIS schedules, policies, and
procedures.
Descriptive Information
, mentioned above, is
the set of information, consist-
ing primarily of Package Descriptions, which is provided to Data Management
to support the finding, ordering, and retrieving of OAIS information holdings by
Consumers.
While in general this type of information is extremely diverse, there are some
inventory activities which seem particularly basic and which requires relatively
straightforward collection of information.
This domain independent type of Descriptive Information, used by the Data
Management entity, is the simple catalogue of which Content Information is in
which Archival Information Package.
16.3 Discipline Dependence: Toolboxes/Libraries
As noted in the description of the Registry/Repository, individual pieces of
Representation Information are opaque binary objects to it. However the
Representation Information must contain specific information about some specific
data objects, and must include discipline dependence.
The discipline specificity is captured using a variety of tools and techniques; the
umbrella term “toolbox” includes all of these.
Chapter 7
provides an overview of
the types of Representation Information.
Discipline specificity is also needed for parts of the Preservation Description
Information (PDI), and an umbrella toolbox is needed here also. PDI is discussed in
more detail in
Chap. 10
.
The term toolbox should not be interpreted as a Graphical User Interface (GUI),
rather is just an umbrella term which could include, for example, many GUIs, soft-
ware libraries, processes and procedures. There are a number of technologies which
appear in many different guises.
16.4 Key Infrastructure Components
Based on the OAIS Reference and Functional Models, CASPAR has defined the
basic infrastructure for providing digital preservation services, called the CASPAR
