Summary:

This book focuses on the techniques developed by the LOTAR (Long Term Archiving and Retrieval) project, a collaboration among the major US and European aerospace companies. Long-term archiving models follows LOTAR by taking the exchange of mechanical CAD file as the paradigm for long-term retention and developing general principles for model archiving. These include electrical systems, composite parts, systems engineering and requirements engineering. The increasing availability of model-based software has made the problems of long-term model sustainment more visible and pressing for a solution. Industries following LOTAR today include aerospace, automotive, nuclear and ship building. In the aerospace sector, the challenges are even bigger.
