本标准描述了用于内容到运行时服务通信的ECMAScript应用程序编程接口（API）。本标准基于a？CMI互操作性指南，a？3.4版，由航空工业CBT委员会（AICC）定义。它用ECMAScript语言定义了公共API服务，该服务支持与学习相关的内容和用于支持学习管理的运行时服务（RTS）之间的信息通信。本标准不涉及RTS和相关管理系统之间可能传输的数据结构、数据安全或通信。

This standard describes an ECMAScript application programming interface (API) for content-to-runtime-services communication. This standard is based on an API defined in the "CMI Guidelines for Interoperability," version 3.4, defined by the Aviation Industry CBT Committee (AICC). It defines common API services in the ECMAScript language that enables the communication of information between learning-related content, and a runtime service (RTS) used to support learning management. This standard does not address the data structures that may be transmitted, data security, or communication between an RTS and a related management system.
