Template
-----------

A template is an **artifact**, and uses artifact-mapping-resource (see :ref:`artifact_type` -> Mapping) 
and artifact-template-velocity (see :ref:`artifact_type` -> Velocity).

A template is **parameterized** and each parameter must be defined in a corresponding **mapping file**.

In order to know which mapping correlates to which template, the file name must start with an ``artifact-prefix``, 
serving as identifier to the overall template + mapping.

The **requirement** is as follows:

``${artifact-prefix}-template``

``${artifact-prefix}-mapping``
