This is the VISSv3.0 release candidate 0.

The specification source of truth are the three HTML documents in the spec directory of this Github.
As reading HTML source code is not so fun it is possible to read them either in

  • the three PDF rendered artefacts found in this release candidate (see comment below regarding these).
  • or via the links to rendered versions found in the README of the root directory.
  • or by downloading one of the Source code artefacts, unpacking it, and then clicking on one of the HTML files in the spec directory, which then is automatically rendered by the browser.

Please observe that the files in the spec/resources directory are not rendered in full in the PDFs.
They can be read by opening the files in https://github.com/COVESA/vehicle-information-service-specification/tree/main/spec/resources.
