LOng Term Archiving and Retrieval - LOTAR


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 harmonized with e.g. the Recommendation 4958 for long-term archiving of the German Association of the Automotive Industry (VDA) and are based on the ISO 14721, Open Archival Information System (OAIS) Reference Model. The documents for the standard are published as the EN9300 series and, in cooperation with the AIA, also as the National Aerospace Standard (NAS).

LOTAR International is a project being conducted by leading OEMs and suppliers in the aerospace and defense industry under the joint auspices of ASD-STAN, AIA, PDES Inc. and the ProSTEP iViP Association.

Close cooperation with the PDES, Inc. / ProSTEP iViP CAx Implementor Forum ensures implementation reliability.

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

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

The LOTAR development of a worldwide-accepted standard for long-term archiving of a 3D master and product structure is an international collaboration of the Aerospace Industries Association of America (AIA) and the AeroSpace and Defence Industries Association of Europe for Standardization (ASD-STAN), under the supervision of the International Aerospace Quality Group (IAQG).

The results of LOTAR will be released as EN 9300 and NAS 9300 series. Part of the series is already released.
