             Summary: how to differentiate get_propertiy and get_attribute
                 Key: TOSCA-192
                 URL: https://issues.oasis-open.org/browse/TOSCA-192
             Project: OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC
          Issue Type: Improvement
            Reporter: Shitao Li


In the wd03-Rew06 document, section 17, it said that "
It should be noted that the actual port value of the notification_port attribute may or may not be the value 8000 as requested on the property; therefore, any node that is dependent on knowing its actual “runtime” value would use the get_attribute function instead of the get_property function."

but how could the user know that the value of the property set in the template would be changed at the runtime. what if in this example, user uses get_property function, it will only get the value of "8000" no matter the notification_port changed at runtime, or it can get the actual value?

do we have an example that the property value should be changed at the runtime even through the value of the property has been set in the template?
