LOTAR Standard


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.

LOTAR Overview on Parts

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.

Data Domain Specific Parts

The Data Domain Specific Parts contain requirements and definitions for specific types of data related to long time archiving and retrieval. So far descriptions for CAD 3D model data and Product Data Management (PDM) data exist.

LOTAR Processes & Use Cases

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.
