# Target identity

> A reference to the entity about which the model produces output.

When applicable, a reference to the entity about which the model produces output. For example, a patient
ID number for clinical predictions or a claim ID for administrative tasks. Some models may not produce
outputs about discrete targets, making this field optional.
