However, it specifies the information necessary for software modules, including safety-related information.This document focuses on interfaces, properties, composition and execution-specific information, which are related to software modules. The information is utilized in the runtime and design/developing stages. In particular, the interfaces are classified and described into two types such as variables and methods. The document can also be applied to the following software lifecycle stages: the design stage, development stage, operation stage, and maintenance stage.
