ISO 14721 is the international standard defining the Open Archival Information System (OAIS) reference model, a conceptual framework for the long-term preservation of digital information. It specifies the functional entities, information packages and responsibilities of an archive committed to preserving content and making it accessible to a designated community over time. As the foundational model for digital preservation, it underpins repositories, audit and certification frameworks, and cultural heritage and scientific data archives.
- ISO 14721 specifies the Open Archival Information System reference model, the foundational framework for Digital Preservation.
- Published by ISO, it defines the functions and information packages an archive needs for Long Term Preservation.
- It is widely applied in Cultural Heritage Preservation and depends on rich Metadata Standard practice.
Overview
- OAIS provides a common vocabulary and conceptual model rather than an implementation. It describes an archive in terms of producers who deposit content, a designated community who consume it, and management who set policy.
- Information moves through the archive as packages: Submission Information Packages from producers, Archival Information Packages held internally, and Dissemination Information Packages delivered to users, each bundling content with preservation metadata.
- Functional entities — ingest, archival storage, data management, administration, preservation planning and access — divide the archive’s responsibilities, giving repositories a shared blueprint and a basis for trustworthy-repository audit.
Key aspects
- The producer, consumer and management roles framing archival responsibility.
- The SIP, AIP and DIP information-package model.
- Six core functional entities including preservation planning.
- Preservation description information ensuring future understandability.
- A basis for repository certification and audit frameworks.
Applications
- National libraries, archives and research data repositories.
- Cultural heritage digitisation and long-term media preservation.
- Scientific and spatial data archives requiring decades-long accessibility.
