This part covers long term archiving (LTA&R) for product management data and relevant process related information (e.g. product structure requirements). Regarding process related information, only the process results are considered in scope as these have stable and static characteristics. The workflow used to create the information is not in scope. The resulting information, e.g. change authorization document, approvals/signatures, CAD models, attribute data, are in scope. Product management data closely reflects the local business and data handling processes of each company. Therefore, an open standard can define only a common generic subset of the overall requirements. Other data that are only of local relevance or dependent on the local application environment are defined by local procedures. For each application environment, the complete set of standards, methods, and procedures related to the archived product management data shall be defined and documented by open standards, industry standards, or company standards and procedures. It is strongly recommended to use open standards whenever possible to ease data exchange, sharing, archiving, and ability to audit. Three main objectives for LTA&R of product management data are: - Enable the proper retrieval of archived primary technical data when performing queries relative to product structure, relationships, effectivity, status, etc., - Preserving the links between primary technical data and the associated product management data, - Providing all relevant properties of primary technical data as contained within the associated product management data.
