TS EN 9300-011

TS EN 9300-011 addresses the reference process description for preparing 3D, CAD and PDM data for long-term archiving within the LOTAR framework used in aerospace. It is a process-oriented standard: rather than defining design rules for the product itself, it explains how digital technical product information is prepared so that it can be preserved and retrieved over the long term.

Where data preparation fits in LOTAR

In general technical terms, 3D CAD models and PDM data carry much more than geometry. They also include product structure, relationships, revision information, attributes and, often, essential lifecycle context. The main challenge in long-term archiving is keeping that information intelligible and usable even after the original software environment is no longer available. The data preparation step covered by EN 9300-011 provides a conceptual process for organizing, selecting and readying content before it enters the archive package and the later preservation workflow.

Technical value of this part

• Describes, at process level, how 3D and PDM data should be handled for long-term preservation.
• Expands the data preparation element of the archiving approach overviewed in EN 9300-010.
• Provides a reference process description for preserving geometry, relationships and management data together in aerospace product documentation.

Its value lies in treating archived digital product information as a coherent technical asset rather than as isolated files. That helps organizations plan more consistently for future access, validation and information integrity. As a part of the LOTAR family, TS EN 9300-011 defines the preparation stage that supports long-lived management of digital engineering information in aerospace.
