A near-final draft of the Reference Model for an Open Archival Information System (OAIS) has been made available for error-checking review.
Here's an excerpt:
This document is a technical Recommendation for use in developing a broader consensus on what is required for an archive to provide permanent, or indefinite long-term, preservation of digital information.
This Recommendation establishes a common framework of terms and concepts which comprise an Open Archival Information System (OAIS). It allows existing and future archives to be more meaningfully compared and contrasted. It provides a basis for further standardization within an archival context and it should promote greater vendor awareness of, and support of, archival requirements.
