PurposePurpose
Standardize the relationships and interactions between an information Producer and an Archive— Abstract Model
— Terms and Concepts Define a methodology
— Allows all actions to be structured within this context— Covers times from first contact by Producer until all
information objects are received by the Archive
Provide guidance on the specialization of the methodology to meet the needs of classes of archives, or of specific archives

Management
Producer Consumer
Producer is the role played by those persons, or client systems, who provide the information to be preserved
Management is the role played by those who set overall OAIS policy as one component in a broader policy domain
Consumer is the role played by those persons, or client systems, who interact with OAIS services to find and acquire preserved information of interest
10041267M-4
ScopeScope Identifies different phases in process of transferring
information between Producer and Archive Defines objectives of each phase
— Actions to be carried out during each phase— Expected results from end of each phase
General framework able to be re-used for all processes related to Producer-Archive interactions
Basis for development of additional related standards Basis for development of software tools to assist in
different stages of the interactions between Producer and Archive

ApplicabilityApplicability
All archives conformant to OAIS Reference Model
May be of interest to archives not conformation to OAIS Reference Model
Relevant to archives holding physical as well as digital materials

Methodology ConformanceMethodology Conformance
Methodology used by an archive for a particular ‘archive project’ (acquiring a set of information)– Conforms when all actions in this standard have been
considered and implemented as appropriate
Methodology has been specialized or extended to be a Community Standard, it conforms when:– All actions have been considered and incorporated
appropriately
– Methodology for creating the Community Standard has addressed the various work phases defined in section 4
