Intelligent transport systems - Using web services (machine-machine delivery) for ITS service delivery - Part 1: Realization of interoperable web services (ISO 24097-1:2009, IDT) (Swedish Standard)
This part of ISO 24097 establishes a Service-Oriented Architecture (SOA) for the realization of interoperable Intelligent Transport Systems (ITS) web services (WS). Web service behaviour is described at the metadata level (i.e. a higher level of abstraction) to enable auto-generation of both a “Service requestor” program, as well as a “Service provider” program.
The principal entities involved in a web service scenario are “Service provider“, “Service requestor” and “Registry” (see Figure 1). The registry includes business information and technical information such as interface and policy. A service provider interacts with the registry to enable it to “publish” the service he/she is able to provide. The service is characterized by a web service interface describer in the form of a standardized web service description language (WSDL) and policy (WS-Policy). A service requestor interacts with the registry to “discover” a provider for the service he/she is seeking. That interaction takes place through Universal Description Discovery and Integration (UDDI) dialogue and endpoint reference (EPR). Once the service requestor identifies a service provider, he “binds” to the service provider via an SOA protocol.
