CCSDS/ISO Producer-Archive Interface Methodology Abstract Standard Don Sawyer /NASA/NSSDC

1. CCSDS/ISOProducer-Archive Interface Methodology Abstract Standard Don Sawyer /NASA/NSSDC 30 October 2002

2. Purpose • 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

3. Model View of an OAIS Environment • 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 OAIS (archive) Producer Consumer Management

4. Scope • 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

5. Applicability • 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

6. Methodology 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

7. Document Organization • Section1 • Purpose, Scope, Applicability, Conformance • Section 2 • Overview of methodology, players, their relationships, activity phases • Section 3 • Detailed analysis of the four phased defined • Preliminary definition phase • Formal phase • Transfer Phase • Validation Phase • Section 4 • Work stages leading to a Community Standard • Annex: Overview of OAIS Reference Model applicable to this standard
