You can use node and flow properties in a variety of ways with SPSS Modeler. They're most commonly used as part of a script: either a standalone script, used to automate multiple flows or operations, or a flow script, used to automate processes within a single flow. You can also specify node parameters by using the node properties within the SuperNode. At the most basic level, properties can also be used as a command line option for starting SPSS Modeler. Using the -p argument as part of command line invocation, you can use a flow property to change a setting in the flow.

The example s:sample.max_size illustrates that you don't need to spell out node types in full.

The example t.direction.Age illustrates that some slot names can themselves be structured—in cases where the attributes of a node are more complex than simply individual slots with individual values. Such slots are called structured or complex properties.
