Category:Variable

This category uses the form VariableForm.

Types

There are four types: driver, model, parameter, external model. An integrity test should be written her to check the consistency

• drivers are external model variables that are used for the core models. Constraint: may not occur in the range of hasOutputVar property
• parameters are variables that are rather static and mostly used as input for one modelcomponent; Constraint: may not occur in the range of hasOutputVar property
• model variables are variables that are calculated by a model or impact component, Some are used as input for another model component, others are final output. Constraint: must occur in the range of hasOutputVar property
• external model variables are variables that originates from external models (or databases) and are used in the impact components. Constraint: may not occur in the range of hasOutputVar property

Not used

Not used Drivers

If no results here, then it is ok

Not used parameters

If no results here, then it is ok

model variables not used as input: final output

This is not wrong, but the list can be checked

Not used External model variables

If no results here, then it is ok

Consistency check

Model variables that are not an output

If no results here, then it is ok

Drivers that are an output

If no results here, then it is ok

Parameters that are an output

If no results here, then it is ok

External model variables that are an output of IMAGE component

If no results here, then it is ok

Impacts

Model variables that are final output and not impact variables

===Model variables that are impact variabels
