Given its central role in abstracting vehicle signals into standardised data the Vehicle Signal Specification (VSS) is most often mentioned in the terminology below when discussing data models. In Data Centric Architectures it is seen as beneficial that the same technology stack be used for multiple data domains and that is the case here.

Rather than make the text unnecessarily long by continuously spelling it out in the definitions it should be assumed that the majority of components will also process data using other data models. A central Data Store for example is likely to store data from VSS, native signals and other models such as personal and privacy data.
