+Expression
+-------------------------------------
+
+TOSCA provides for a set of functions to reference elements within the template or to retrieve runtime values.
+
+**Below is a list of supported expressions**
+
+.. tabs::
+
+ .. tab:: get_input
+
+ **get_input**
+
+ The **get_input** function is used to retrieve the values of properties declared
+ within the inputs section of a TOSCA Service Template.
+
+ Within CDS, this is mainly Workflow inputs.
+
+ `TOSCA specification

+
+ **Example:**
+
+ `<https://github.com/onap/ccsdk-cds/blob/master/components/model-catalog/blueprint-model/test-blueprint/golden/Definitions/golden-blueprint.json#L210>`_
+
+ .. code-block:: JSON
+
+ "resolution-key": {
+ "get_input": "resolution-key"
+ }
+
+ .. tab:: get_property
+
+ **get_property**
+
+ The **get_property** function is used to retrieve property values between modelable
+ entities defined in the same service template.

+ **Example:**
+
+ TBD
+
+ .. tab:: get_attribute
+
+ **get_attribute**
+
+ The **get_attribute** function is used to retrieve the values of named attributes declared
+ by the referenced node or relationship template name.
