Content DescriptionISO 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. About ISOISO, the International Organization for Standardization, brings global experts together to agree on the best way of doing things – for anything from making a product to managing a process. As one of the oldest non-governmental international organizations, ISO has enabled trade and cooperation between people and companies all over the world since 1946. The International Standards published by ISO serve to make lives easier, safer and better. |
