TS EN 9300-001

TS EN 9300-001 defines the structural foundation of the LOTAR family for long-term archiving and retrieval of digital technical product documentation in aerospace. It sets out how the EN 9300 series is organised and what kind of content framework is used for preserving product data such as 3D CAD and PDM information over time.

How the standard family is organised

This part shows that EN 9300 is not a single monolithic document but a set of separate standards designed to address different business needs. In general technical terms, that kind of modular structure makes it easier to apply long-term archiving concepts to different data types, operational contexts, and future archive formats. LOTAR is widely understood as an approach aimed at keeping digital product-definition data readable and retrievable in the long run.

Why structure matters for digital product data

3D models, CAD files, and PDM records can carry different layers of information, including geometry, associated technical content, administrative state, and product-lifecycle context. Long-term archiving therefore means more than storing files; it also means preserving the context and structure needed to interpret them later. This document part provides that top-level organisation, creating a consistent framework for the rest of the EN 9300 series.

• It is the structural part of the LOTAR standard family.
• It addresses the framework for long-term preservation of digital product and technical data.
• It defines how the EN 9300 series is split into parts for different business requirements.
• It provides a basis that can be extended for future long-term archiving formats.
