Comment: Add links to VISS specifications
Warning

This is a historical page.  As part of preparation work for the CCS project and the initial stages of working towards a unified approach to vehicle data, all related projects were surveyed and this was the "snapshot" view at the time.  By now these projects have progressed, and we have continued convergence and collaboration in this area.  For up to date status of the VISSv2 and other related projects in W3C and elsewhere, we recommend starting at the CVII initiative.

GET VSS-Root/Car/Drivetrain/InternalCombustionEngine/RPM HTTP/1.1

  • ...and Wildcards:

/VSS-Root/Cabin/Door/*/*/IsLocked HTTP/1.1 

(warning) NOTE: Some discussions whether wildcards should be completely replaced by new Queries approach.
