LOng Term ARchiving - LOTAR

Term

December 2001 till December 2009

Activities

The archiving of product data and making this data available in the event of product liability litigation poses a challenge – and not only with regard to regulatory restraints. The LOTAR project group is playing a leading role in developing a standard for the long-term archiving of digital product data in the aerospace industry. The objective of the project group is to establish methods, processes and a data model for archiving 3D geometry data and product structure information. In order to establish the results as a standard for the European aerospace industry within the EN9300 series as quickly as possible, they will be submitted to the AeroSpace and Defence Industries Association of Europe - Standardization (ASD-STAN) for publication. Publication will mean that the standard is binding for the entire European aerospace industry.
