Archivage long terme et récupération

This document contains a current state assessment of long term archiving and retrieval within the automotive industry and is a future state vision that describes the four LTAR recommendations and the test bed capability for assessing an enterprise’s LTAR capability.

The SASIG Long Term Archiving & Retrieval Project is developing a set of recommendations to guide companies to effective and efficient archival and retrieval practices. This document addresses the set of format recommendations. In particular this document aims to provide a company with the key functional and technical elements to consider when choosing an archival format(s).

This document aims to provide a company with the key activities, inputs, outputs, controls and mechanisms needed to fully support the long term archiving and retrieval of product definition information. Using official standards as the foundation framework, the SASIG Long Term Archiving & Retrieval Project developed seven comprehensive process flow models depicting the activities and data flows needed to support archival and retrieval from the automotive perspective.

This document aims to provide an organization with the key functional and technical elements to consider when choosing a LTAR time period for a particular artifact of product data. Such a period should be retained to meet governmental or organizational requirements. These constraints can be associated with the intellectual property verification and validation; maintenance and repair actions; legal obligations associated with patent litigation, product liability, and tax considerations; and an organization’s design knowledge preservation desires. By correlation, the time period recommendation can be used to determine routine and timely disposal of a product data artifact.

This document aims to provide a comprehensive explanation of the four checking and validation functions that define the LTAR Quality Assurance strategy.

The four functions are: Product Data Quality (PDQ) Check, Archival Rules Check, Fixity Check, and Equivalence Validation. Included is a detail description of what each function does, why it is needed, and when it should be performed.
