LOTAR Standard Welcome » LOTAR Standard Welcome Why LOTAR? LOTAR Organization LOTAR Workgroups Dates & Communication LOTAR Standard Overview on Parts Related Documents Industry Use News Links Overview on Parts The LOTAR group decided to split the documentation according to the agreed work packages in different parts. The modular based concept provides a higher degree of usability and adaptability. Basic Parts The Basic Parts provide an overview about the essential information on long time archiving and retrieval of 3D model and product structure data.

So far descriptions for CAD 3D model data and Product Data Management (PDM) data exist. The LOTAR information Domain specific standards do not define new product information model standards, but they reference the appropriate ISO 10303 STEP Application Protocols. When limitations of these standards are identified, the LOTAR project contributes to the enhancements of these standards. Example: LOTAR contributions to the AP 242 project and to the harmonization for PDM between AP 242 and AP 239 PLCS.
