LOng Term Archiving and Retrieval - LOTAR


With the emergence of digital data based processes including model based definition, requirements were identified which predicate the need for a long term data retention solution(s) to meet the regulatory and business requirements. Traditional legacy retention and retrieval methods do not support complex digital product definition data.

The objective of LOTAR International is to develop, test, publish and maintain standards for long-term archiving (LTA) of digital data, such as 3D CAD and PDM data. These standards will define auditable archiving and retrieval processes. Use of the standard series by other branches of industry such as the automotive or shipbuilding industry is possible. The results are based on the ISO 14721, Open Archival Information System (OAIS) Reference Model. The documents for the standard are published as the European Norm (EN) 9300-xxx series under ASD-STAN in Europe and, in cooperation with the AIA, under the National Aerospace Standard (NAS) 9300-xxx.

LOTAR International is a project being conducted by leading OEMs and suppliers in the aerospace and defense industry under the joint auspices of Aerospace Industries Association of America (AIA) and the AeroSpace and Defence Industries Association of Europe for Standardization (ASD-STAN), PDES Inc. and the prostep ivip Association.

Close cooperation with the PDES, Inc., prostep ivip and AFNet CAx and PDx Implementor Forums ensures implementation reliability.

The LOTAR project consortium consists of user companies from around the world. Member companies include Airbus, BAE Systems, Boeing, EADS, Eurocopter, General Dynamics, Lockheed Martin, SAFRAN, Sandia, and others.

Goals of the project include:

  • Developing, publishing and maintaining a standard series for archiving and retrieval of product data
  • Standardization of referred and needed methods, process modules and data models
  • Providing methods, process modules and data model(s), to enable long-term archiving and retrieval of CAD and PDM data, but e.g. also for electrical, composite design data
  • Development of recommendations for practical introduction of long-term archiving of relevant data at industry
  • Enabling commercial solutions based on user requirements in cooperation with CAx-IF testing and funded pilot projects
