# Accessing a Concept PropertyAtom

Access to a concept PropertyAtom is defined with the syntax.

Syntax for accessing a concept property:

    instanceName.propertyName

where instanceName is the identifier of the concept instance, and propertyName is the name of the concept property that you want to access.

For example, to get the current value of the cost PropertyAtom:

    int x = instanceA.cost;

For example, to set a value with the current system timestamp:

    instanceA.cost = value;

Note: If the history size is `0`, TIBCO BusinessEvents does not record a timestamp.
Note: Rule dependency and rule condition re-evaluation are performed only on concept properties.

This re-evaluation is not performed on an attribute such as `@parent`.
