Title (German)

Luft- und Raumfahrt - LOTAR - Langzeit-Archivierung und -Bereitstellung digitaler technischer Produktdokumentationen, wie zum Beispiel von 3D-, CAD- und PDM-Daten - Teil 004: Beschreibungsmethoden; Deutsche und Englische Fassung EN 9300-004:2013

Overview

Companies within the aerospace industry need to keep data to fulfil business, certification and legal requirements. For modern definitions this data is usually digital. These requirements lead to requirements which shall be considered regarding the retention of digital data; amongst others, how can be ensured that digital data is not altered and is also readable in the future. In this context the aerospace industry requirements shall be taken into account. Currently, for CAD software, the period between versions is of the order of 6 months to 12 months, while between generations is of the order of 3 years to10 years. This shall be compared to an aircraft life cycle which may be 30 years to 50 years or longer. For digital data, the challenge is that the data are often stored in a proprietary, native format and will most likely become not interpretable after a time. The use of a neutral archiving data format safeguards the interpretability of the stored data for a much longer time, perhaps for the entire retention period. The DIN EN 9300 standard series contains the multidimensional aspects of Long-Term Archiving and Retrieving of digital technical product documentation on the basis of standardized formats in combination with permanent and frequent migration into other storage media and, if necessary, data formats. DIN EN 9300-004 provides an overview of the description methods used to support an equal level of understanding of the standards context. These methods are divided into four main categories: 1) scope and scenario description; 2) process description; 3) data; 4) system architecture. For scope and scenario description, the modelling methods are based on Unified Modelling Language (UML) Use Case diagrams. The process descriptions are done using Simplified Activity diagrams. Data modules are described by Express G diagrams. Rules and constraints are described via Express-Where-Rules. Further descriptions, for example, for a data dictionary, are based on tabular forms. If not otherwise specified by contractual requirements, DIN EN 9300-004 is applicable to all records which provide objective evidence covering: a) archiving requirements; b) data quality requirements. DIN EN 9300-004 is applicable to existing records, on current and earlier products, produced using previous regulations. The EN 9300 standard series was prepared jointly by ASD-STAN and the PROSTEP iViP Association. The PROSTEP iViP Association is an international non-profit association in Europe with nearly 200 members from leading industries, system vendors and research institutions in IT-based engineering. It is actively engaged in product and process data standardization activities at European and worldwide levels. This document EN 9300-004:2012 has been prepared by ASD-STAN, Technical Section General. The European Committee for Standardization (CEN) declared the Aerospace and Defence Industries Association of Europe (ASD-STAN) responsible for the preparation of European standards (EN) for the field of aerospace. ASD became the associated body (ASB) of CEN by the agreement dated 1986-10-03. The responsible German standardization committee is Working Committee NA 131-05-01 AA "Grundlagen und Managementverfahren (Spiegelausschuss zu ISO/TC 20/SC 14)" ("Basic principles of management processes (Mirror committee of ISO/TC 20/SC 14)") of the Aerospace Standards Committee at DIN.
