ISO 20078‑2 defines how to access Resources on a Web services interface of an Offering Party using the Hypertext Transfer Protocol Secure (HTTPS). For such access, the Representational State Transfer (REST) architectural pattern is chosen as a common way to format Resource paths
Some specific extensions to this pattern are defined to allow for asynchronous Resource requests, such as, for example, forcing readouts of data from a connected vehicle.
ISO 20078‑2 on access- extended vehicle (ExVe) web services is applicable to:
ISO 20078‑2 defines the usage of a common communication protocol that enables Access to Resources (URIs), thereby standardizing how an Accessing Party can Access Resources via Web services of an Offering Party, using Hypertext Transfer Protocol (HTTP) over Transport Layer Security (TLS); i.e. HTTP Secure (HTTPS). This helps the manufacturer in standardizing the access protocol.
ISO 20078‑2 selects Representational State Transfer REST for using a common way to represent data, aggregated information, and functions (Resources) [ISO 20078‑2].
As personal data protection rights are becoming stronger in several countries, ISO 20078‑2 defines and recommends by its design, common methods to handle data protection and data privacy issues when accessing personalized vehicle data, information or functionality via web services. This helps you to comply with regulations.
