OAIS

The Open Archival Information System (OAIS) is an ISO reference model (ISO 14721) describing how an archive should accept information packages, preserve them, and provide access to a designated community. It supplies shared vocabulary—Submission, Archival, and Dissemination Information Packages (SIP/AIP/DIP)—used across libraries, space agencies, and research repositories.

Influence

OAIS does not prescribe a single software stack; instead it guides requirements for Digital preservation systems, audit frameworks, and metadata packaging (including web and WARC workflows).
