Open Archival Information System (OAIS) model

The Open Archival Information System (OAIS) is a framework that ensures long-term preservation and access to digital information. It defines how digital content—like documents, videos, or data—is managed, stored, and made available to users over time. OAIS describes roles such as ingesting new data, archiving it securely, maintaining its usability, and providing access to researchers or the public. Think of it as a detailed blueprint for libraries or archives that want to keep digital information intact, understandable, and accessible for future generations.
