【国外标准】 Information technology Multimedia application format (MPEG-A) Part 6: Professional archival application format

The purpose of the PA-AF is to provide a standardized packaging format for digital files. This packaging format can also serve as an implementation of the information package specified by the Reference Model of Open Archival Information System (OAIS). The OAIS Reference Model is a framework for understanding and applying concepts necessary for long-term digital information preservation (where "long-term" is long enough to be concerned about changing technologies). In addition, PA-AF can also be used as an intermediate or exchange packaging format for any kind of multimedia content.
