Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 31, Data communication.

This second edition cancels and replaces the first edition (ISO 20078-2:2019), which has been technically revised.

The main changes are as follows:

• added definition of a push method, allowing the offering party to push resources to the accessing party according to subscription;
• added definition of reusable subscription profiles, used to store URI locations and authorization information from the accessing party and used by offering party to push subscribed resources;
• defined requirements for container management API;
• added Annex A and digital Annex B describing container management API;
• revised error format;
• redefined resource versioning.

A list of all parts in the ISO 20078 series can be found on the ISO website.

1 Scope

This document defines how to access resources on a web-services interface of an offering party using the Hypertext Transfer Protocol Secure (HTTPS). Resources can be accessed through request/reply and/or requested to be pushed.

The Representational State Transfer (REST) architectural pattern is chosen as a common way to format resource paths both for request/reply and push. 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.
