Project Title

OAIS-IF Core Specification



Document Number


2.01 Data Archive Interoperability Working Group

Document Type


Description of Document

The purpose of this document is to provide the interfaces and protocols for the CCSDS and International Organization for Standardization (ISO) Open Archival Information System Interoperability Framework (OAIS-IF) Core Specifications. It is a supplement to the overarching OAIS Reference Model standard. The purpose of the set of standards which make up OAIS-IF is to define interfaces and services which go beyond the exchange of data (as in communications standards) and instead will enable the exchange of information.

Applicable Patents

There are no patent issues for this technology that are known by the CCSDS community
