AIA NAS9300-002

This standard is a part of the NAS9300 Series. This standardaddresses requirements for the long term archiving of digitalproduct information, applicable to the international aerospaceindustry.

Data shall be available to meet regulatory, legal, contractualand business requirements.

Initially, this document sums up the main business requirementsfor long term archiving of digital product data. Although theserequirements are not in themselves normative, when making dataavailable over an extended period, it is a fundamental principlethat the contextual data needed to interpret the data is alsoavailable.

This standard uses the OAIS reference model to providecomparability with other approaches to keeping informationavailable. However, OAIS is a standard reference model forcomparison, not a standard for implementation. Consequently, thisdocument defines requirements for processes (and associatedtechnologies) intended to make data available for the life of aproduct, and does so in terms of the OAIS model.

In dealing with traditional media, the differences betweensubstantial change and unimportant “surface” change are generallyself-evident. For example, the yellowing of paper over time, or theencrustation of a gravestone with lichen do not loose theinformation contained, whereas the loss of pages of a document, orthe erosion of the stone do so, and archiving focuses on thepreservation of the medium. For digital product data, the medium isunimportant, but the content can be corrupted. The subject of the(many) remaining parts of this standard is the identifciation ofthe information that shall be uncorrupted if digital product datais to be usable in the future, and the consequent refinement ofprocesses and procedures to insure this.

This standard addresses, archiving of digital product datarequired for product definition, such as in three-dimensionalrepresentations a tolerances, material properties, manufacturingdata, etc, specification call-outs, product structure andconfiguration control data, etc. Other parts of the NAS9300standards will cover more specifically the long term archiving of,for example, composites, electrical systems, product analyses andproduct simulation information.

This standard also addresses managing the evolution oftechnologies required to ensure the availability and usability ofthe data for the required archiving period.

This standard is not intended to incorporate company specificrequirements and does not dictate specific organizationalstructures within a company. This standard does not specify adesign or an implementation of an archive system. Actualimplementations may distribute responsibilities or break outfunctionality differently.

This standard assumes that all requirements for configurationmanagement of the product data are in place and therefore are notspecifically described in this document.

If an organization chooses to implement requirements beyondthose outlined in this requirements document, those additionalrequirements shall not conflict or negatively impact therequirements contained in this document.

Purpose: This standard establishes legal and other businessrequirements for processes intended to preserve digital data. Dataneed to be stored and maintained so that data are retrievable andusable for the required archiving period. In addition, for somebusiness requirments, data need to be authentically preserved andaccessed.

This standard is intended to allow for different implementationsbased on a company’s specific business environment.
