OAISviide

OAISviide is a framework developed to provide a standardized approach to the long-term preservation of digital information. It is an acronym for the Open Archival Information System Reference Model. The OAIS model is not a specific software system or implementation but rather a conceptual model that outlines the functional entities and information that must be present in an archival system. Its primary purpose is to ensure that digital information can be accessed and understood in the future, even as technologies evolve and formats become obsolete.

The OAIS model defines several key functional entities. These include the Ingest function, responsible for receiving digital objects from producers; the Data Management function, which handles the storage and retrieval of archived information; the Access function, which allows users to find and retrieve digital objects; the Administration function, for managing the overall system; and the Preservation Planning function, which oversees the long-term viability of the digital objects.

Central to the OAIS model is the concept of the Archival Information Package (AIP). An AIP is a digital object that has been designated for preservation and contains the information necessary to understand and use the object over the long term. This includes the data itself, as well as metadata that describes the object's context, provenance, and format. The OAIS model guides the creation, management, and preservation of these AIPs. It has become a foundational standard in digital preservation efforts worldwide, influencing the design of digital repositories and the development of preservation policies.
