ISO/IEC 24791-2:20 11定义了提供对射频识别(RFID)标签数据的操作的接口，包括但不限于软件系统基础设施(SSI)内的读取、写入、收集、过滤、分组以及事件订阅和通知。 具体而言，ISO/IEC 24791-2:20 11定义的接口提供以下特征: 在适合数据管理在ISO/IEC 24791-1中定义的SSI架构中的位置的抽象级别上，完全支持ISO/IEC 24791-2:20 11支持的air协议的命令和响应； 可以应用于不同网络绑定和编码机制的命令和操作的抽象定义； 支持ISO/IEC 15962中定义的编码机制； 适合数据管理在ISO/IEC 24791中定义的SSI体系结构中的位置的体积缩减、格式或结构修改、数据分析和数据访问-1; 以客户端控制的格式报告数据以支持应用程序或数据管理，无论是在SSI内部还是外部。 ISO/IEC 24791-2:20 11全部由EPC全球应用级事件标准组成，并进行了扩展，以进一步支持ISO/IEC 15962和ISO/IEC 18000定义的air协议的操作。

ISO/IEC 24791-2:2011 defines the interface(s) that provide operations on radio frequency identification (RFID) tag data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification within the Software System Infrastructure (SSI). Specifically, the interface(s) defined by ISO/IEC 24791-2:2011 provide the following features:

• full support for the commands and responses for air protocols supported by ISO/IEC 24791-2:2011 at an abstraction level appropriate for Data Management's position in the SSI architecture defined in ISO/IEC 24791-1;
• an abstract definition of commands and operations that can be applied to different network bindings and encoding mechanisms;
• support for the encoding mechanisms defined in ISO/IEC 15962;
• volume reduction, format or structure modification, data analysis, and data access appropriate for Data Management's position in the SSI architecture defined in ISO/IEC 24791-1;
• reporting of data to support application or data managing in formats controlled by the client, either inside or outside of SSI.

ISO/IEC 24791-2:2011 is composed of the EPCglobal Application Level Events Standard, in its entirety, with extensions to further support operation with ISO/IEC 15962 and the air protocols defined by ISO/IEC 18000.
