管理用Web服务(WS-管理)规范

[中文适用范围]： Web Services for Management (WS-Management) 规范描述了一种基于 SOAP 的 Web 服务协议，用于管理特定领域。这些领域包括管理 PC、服务器、设备、Web 服务和其他应用程序以及其他可管理实体的管理。服务可以仅暴露 WS-Management 接口，也可以将 WS-Management 服务接口与其他许多 Web 服务规范组合使用。这些服务的一个关键应用领域是系统管理。为了促进管理应用程序和可管理资源之间的互操作性，本规范确定了一组核心的 Web 服务规范和用法要求，这些规范和要求暴露了所有系统管理中都包含的公共操作集。这包括以下能力：获取、放置（更新）、创建和删除单个资源实例（如设置和动态值）；枚举容器和内容（如大型表和日志）；订阅由可管理资源发出的事件；执行具有强类型输入和输出参数的特定管理方法。在这些范围领域中的每一个，本规范为符合规范的 Web 服务实现定义了最低实现要求。实现可以超出这组操作进行扩展，并且如果该功能不适合目标设备或系统，可以选择不支持上述功能领域中的一个或多个。本规范旨在满足以下要求：限制 Web 服务协议和格式，以便 Web 服务可以在硬件和软件管理服务中以小 footprint 实现；定义符合性最低要求，而不限制更丰富的实现；确保与 WS-Management 版本 1.0 的后向兼容性和互操作性；确保与其他 Web 服务规范的可组合性。 [外文原描述]： ISO/IEC 17963:2013 describes a Web services protocol based on SOAP for use in management‑specific domains. These domains include the management of entities such as PCs, servers, devices, Web services and other applications manageable entities. Services can expose only a WS-Management interface or compose the WS-Management service interface with some of the many other Web service specifications. A crucial application for these services is in the area of systems management. To promote interoperability between management applications and managed resources, ISO/IEC PAS 17963:2012 identifies a core set of Web service specifications and usage requirements that expose a common set of operations central to all systems management. This includes the ability to do the following: a) get, put (update), create, and delete individual resource instances, such as settings and dynamic values; b) enumerate the contents of containers and collections, such as large tables and logs; c) subscribe to events emitted by managed resources; d) execute specific management methods with strongly typed input and output parameters. In each of these areas of scope, ISO/IEC 17963:2013 defines minimal implementation requirements for conformant Web service implementations. An implementation is free to extend beyond this set of operations, and to choose not to support one or more of the preceding areas of functionality if that functionality is not appropriate to the target device or system. ISO/IEC 17963:2013 intends to meet the following requirements: a) constrain Web services protocols and formats so that Web services can be implemented with a small footprint in both hardware and software management services; b) define minimum requirements for compliance without constraining richer implementations; c) ensure backward compatibility and interoperability with WS-Management version 1.0; d) ensure composability with other Web services specifications.
