The Hierarchical Information Model (HIM) is an evolution of the COVESA Vehicle Signal Specification (VSS) that adds the ability to have multiple trees representing different domains, and representing different types of information. Besides the information type “resource data” that is what is represented by the VSS tree, HIM also supports “service data” where microservices represented by procedures with input and output parameters can be defined. Analogously to VSS, the HIM model does not specify an interface that exposes this information, it leaves this to separate interface specifications. One candidate for this is an evolution of the W3C Vehicle Interface Signal Specification version 2 (VISSv2), that in its current version uses VSS for modelling the data. It is the presenter’s view that this interface can with small modifications be extended to use HIM instead of VSS. This would provide a single interface that can be used to access both information types, that will possibly also be standardized in W3C. The presentation will give the presenter’s view on how this extension could look like.
