other_spatial_object (O, K, I: other_spatial_object(property))

Each pty_electromotive_force may be a property of one other_spatial_object. Inherited from property.


activity (O, K, I: activity(process_data))

Defines the activity which created this instance. Each pty_electromotive_force may be the result of one activity. Inherited from process_data.


data_value (M: ndt_electromotive_force)

The value of the electromotive force.


preferred_flag (O, I: ndt_boolean) (1047)

The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes. Inherited from property.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each pty_electromotive_force may be a member of one or more data_collection. Inherited from e_and_p_data.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each pty_electromotive_force may be depicted by one or more graphical_element. Inherited from e_and_p_data.


process_data_item (I, V: SET[0:?] process_data_item(process_data))

Defines where this data was used by an activity. Each pty_electromotive_force may be the value for one or more process_data_item. Inherited from process_data.

Local rules:

Uniqueness Constraint
other_spatial_object, activity
[I: property] Mandatory Relationship Set
Each PROPERTY must "be a property of" one object.
Supertype path(s):
process_data > property > pty_electromotive_force.
e_and_p_data > property > pty_electromotive_force.
