智能运输系统.智能运输系统服务传递使用的网络服务(机器-机器配送).第1部分:互操作网络服务的实现

[中文适用范围]： 本文档建立了面向服务的架构 (ISOA)，用于实现智能交通系统 (ITS) 的可互操作 Web 服务。Web 服务行为在元数据级别（即更高的抽象级别）上进行描述，以便自动生成“服务请求者”程序和“服务提供者”程序。图 1 显示了 Web 服务场景中涉及的主要实体。它们是服务提供者、服务请求者和“注册表”。注册表包括业务信息和技术信息，例如接口和策略。图 1 还描述了服务提供者和服务请求者的操作。服务提供者与注册表交互，使其能够“发布”所提供的服务。服务以标准化 Web 服务描述语言 (WSDL) 和策略 (WS-Policy) 的形式以 Web 服务接口描述器的形式来表征。服务请求者与注册表交互以“发现”他所寻求的服务的提供者。该交互通过“通用描述发现和集成”（UDDI）对话和端点引用（EPR）进行。一旦服务请求者确定了服务提供商，他就通过 ISOA 协议“绑定”到服务提供商。本文档适用于 ITS 部门之间的 Web 服务以及面向非 ITS 用户的 ITS Web 服务。图 1 — Web 服务实体及其关系  1  [外文原描述]： ISO 24097-1:2017 establishes a Service Oriented Architecture (SOA) for the realization of interoperable web services for Intelligent Transport Systems (ITS). Web service behaviour is described at the metadata level, i.e. a higher level of abstraction, to enable auto-generation of both a ?service requester' program as well as a ?service provider' program. Figure 1 presents the principal entities involved in a web service scenario. They are service provider, service requester, and 'registry'. The registry includes business information and technical information such as interface and policy. Figure 1 also depicts the actions of the service provider and the service requester. A service provider interacts with the registry to enable it to "publish" the provided service. The service is characterized in the form of a web service interface describer in the form of a standardized web service description language (WSDL) and policy (WS-Policy). A service requester interacts with the registry to "discover" a provider for the service he is seeking. That interaction takes place through "Universal Description Discovery, and Integration" (UDDI) dialogue and endpoint reference (EPR). Once the service requester identifies a service provider, he "binds" to the service provider via an SOA protocol. ISO 24097-1:2017 is applicable to inter-ITS sector web services as well as ITS web services for non-ITS users.
