标准摘要
[中文适用范围]： 本部分定义了软件系统基础设施（SSI）中提供对 RFID 标签数据操作接口的标准，包括但不限于读取、写入、收集、过滤、分组以及事件订阅和通知。具体来说，本部分定义的接口提供以下功能： - 在 SSI 架构中数据管理层级适当抽象层面，全面支持本部分所涵盖的空中协议命令和响应（依据 ISO/IEC 24791-1 定义）； - 提供可应用于不同网络绑定和编码机制的命令与操作的抽象定义； - 支持 ISO/IEC 15962 中定义的编码机制； - 提供适合 SSI 架构中数据管理层级的数据缩减、格式或结构修改、数据分析及数据访问功能； - 以受客户端控制的格式（在 SSI 内部或外部）报告数据以支持应用或数据管理。 本部分由 EPCglobal 应用级事件（ALE）标准全文组成，并增加了进一步支持 ISO/IEC 15962 及 ISO/IEC 18000 定义的空中协议的操作扩展。 [外文原描述]： 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.
