The attribute value definition defines the structure of an attribute.
- It associates the attribute with the attribute value.
- In cases where an attribute has more than one attribute value, it defines the default attribute value associated with the attribute. This is important because if a data fetch is requested for the Entity:Attribute, and no attribute value has been supplied, then the system will use the default value.
The complete syntax for an attribute value definition, including the entity, is:
Entity:Attribute!AttributeValue
For example:
Well 1:Flow Rate!Actual
