The Reference Model for an Open Archival Information System (OAIS) was developed for use in facilitating a broad, discipline independent, consensus on the requirements for an archive or repository to provide long-term, preservation of digital information. It was also intended to support the development of additional digital preservation standards.

OAIS, known as ISO 14721:2003, is widely accepted and utilized by various organizations and disciplines, both national and international, and was designed to ensure preservation. The OAIS standard, published in 2005, is considered the optimum standard to create and maintain a digital repository over a long period of time. The OAIS model can be ...

ISO 14721:2012 defines the reference model for an open archival information system (OAIS). An OAIS is an archive, consisting of an organization, which may be part of a larger organization, of people and systems that has accepted the responsibility to preserve information and make it available for a designated community.

The Open Archival Information System ( OAIS) reference model is a conceptual framework for an archival system dedicated to preserving and maintaining access to digital information over the long term.

The OAIS reference model diagram has become the most recognizable conceptualization of a system that addresses digital preservation, but the complete document is often overlooked. It contains six sections and six appendices that provide information vital to organizations trying to implement an "OAIS-compliant" digital archive.

The OAIS Reference Model defines an Open Archival Information System (OAIS) which performs a long-term information preservation and access function. Its key functions are: the Ingest function – the process of accepting information provided by Producers.

The Reference Model for an Open Archival Information System (OAIS) describes components and services required to develop and maintain archives, in order to support long-term access to and under-standing of the information in those archives.

The OAIS information model is built around the concept of an information package, which consists of the object that is the focus of preservation, along with metadata necessary to support its long-term

2019年11月21日 · OAIS (Reference Model for an Open Archival Information System），即开放式档案信息系统模型，它是1995年，在国际标准化组织 (ISO)的请求下，美国国家航空和航天局的空间数据系统咨询委员会 (CCSDS)开始开发的一个旨在对数字资源的存取标准和长期保存的规定概念和参考框架。 后来几经修改扩充，于2002年1月，参考模型最终通过审核，正式成为一项新的国际标准 (ISO：14721)，现已成为国际上很多数字档案的研究和开发的项目优先遵守的标准规范。

The LOTAR White Paper [2002] makes extensive use of the OAIS Reference Model. It uses the Functional Model as the foundation for a set of scenarios summarising the requirements for an industrial repository [§7], the OAIS high-level view of external interactions for data exchange guidelines [§8], and the OAIS perspective on digital migration ...
