POSC Specifications Version 2.2 Epicentre Logical Data Model

0906 Need rule on Coordinate_system

Coordinate_system appears to need a rule which checks that the axes match the constraint. The following is suggested: constraint_type_valid : axis_type_correlation( SELF )

Add new rule.

Add rule that constrains the Ref_quantity_property instance specified by each Coordinate_system_axis to be in the set allowed by the specified instance of Ref_coordinate_system_constraint. This rule is not currently supportable by POSC because functions are not supported. The rule has been included as a remark in order to show the intent of the model.

Added objects:
coordinate_system.sri (Where rule)
