TS EN 9300-005

TS EN 9300-005 addresses the LOTAR framework for long-term archiving and retrieval of digital technical product documentation in aerospace, with a specific focus on authentication and verification. In practical terms, it provides the conceptual basis for checking whether archived digital documents and their content remain intact and trustworthy during storage and later retrieval, especially for data such as 3D models, CAD files and PDM-related information.

Why authentication and verification matter in digital product data

In general technical use, authentication is concerned with establishing that a document or dataset is associated with the expected identity or origin, while verification is about showing that the content has not been altered and still matches the archived state. This distinction matters in engineering documentation because geometry, metadata, relationships and revision history together carry product definition. In a long-term archive, preserving that meaning is as important as preserving the file itself.

What this part contributes to the LOTAR structure

• Fundamental concepts for authentication and verification within an archiving system
• Requirements, methods and recommendations for implementation at a foundational level
• A basis for the Data Domain parts EN 9300-x00, which define qualification measures for document content
• The aerospace long-term preservation and retrieval context for 3D, CAD and PDM data

This part is best understood as a technical foundation for trustworthy archival processes rather than a standalone description of every data domain detail. Its value lies in helping organisations preserve digital product definition in a form that can later be retrieved, assessed and used with confidence.
