ISO/TS 10303-4443 specifies the domain model for modelling and simulation information in a collaborative systems engineering context (MoSSEC).

The following are within the scope of ISO/TS 10303-4443:

• Domain objects in ISO 10303-243, For modelling and simulation information in a collaborative systems engineering context (MoSSEC);
• Business terminology used to describe capabilities in a manner that will facilitate the development of application programmer interfaces for ISO 10303-243, For modelling and simulation information in a collaborative systems engineering context (MoSSEC);
• Business terminology suited for the communication with and understandability by domains experts of Aerospace and Defence, Automotive and other engineering industries;
• Domain Object OpenAPI JSON Schema for ISO 10303-243;
• Necessary subset of ISO/TS 10303-4000, Core Model, to implement the application protocol;
• Mappings to ISO/TS 10303-4000, Core Model.
