Title:	Liaison to ISO TC 20/SC 13 on PA Application Format

JTC1/SC29/WG11 has initiated an activity to specify a standardized format for digital archival contents through the course of ISO/IEC 23000-6 Professional Archival Application Format (PA-AF).

WG11 believes that we have sufficient component technologies such as file format, metadata for content identification and description in which combination of those technologies has considerable potential as the core of a generalised archiving format.

The scope of the work is as follows:

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

The action of archiving digital multimedia content may include processes starting from creation, delivery to the archival system, and dissemination to consumers. The PA-AF specifies the digital archive produced by the archiving process. The PA-AF does not specify how the content is created. The PA-AF does not specify any agreement of how the content should be handled and delivered to the archival system. The PA-AF assumes that the content to be packed into the PA-AF archive is available in an appropriate digital format. The PA-AF also does not specify how the content is disseminated to the consumer as the extracted content from a PA-AF archive is exactly in the format that was input to the PA-AF archive.

The PA-AF specifies the file format for carriage of digital multimedia content, metadata to describe context information related to digital multimedia content stored in the archive, metadata to describe the logical structure of how the digital multimedia content is stored in the archive, identification of processing tools that are applied to the digital multimedia content as pre-processing treatment before they are stored in the archive, as well as data protection and integrity tools, data governance tools, and data compression tools.

WG11 also notes that TC20/SC13 has been successful in seeing its Open Archival Information System (OAIS) Reference Model specification being adopted by other communities. WG11 would like to inform SC13 that PA-AF may provide a technical implementation of the OAIS Reference Model.

An AHG has been set up to progress the work until the 84th meeting in April and details of the mandate are available in N9664.

WG11 invites TC20/SC13 experts to join the AHG reflector and would welcome their input on this activity.
