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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
There is a need to facilitate starting a process of requesting data and functions from the various interfaces
of the extended vehicle as defined in ISO 20077-1.
It is indeed useful to help any requesting party to quickly find the right way to express their needs towards
the right place or the right resource provider without wasting time due to the multiplicity of providers.
This document is intended to facilitate the communication process between independent stakeholders
and vehicle manufacturers (VMs), whereby service providers (SPs) seek to acquire data for the purpose of
developing services.
The proposed process and template aim at helping to initiate a request by independent stakeholders and/or
SPs for data and functions made available by the VMs or their offering parties.

Part 3:
Upstream process to develop services
1 Scope
This document describes the process to initiate and facilitate the communication between independent
stakeholders and vehicle manufacturers (VMs), whereby service providers (SPs) express the intention to
obtain data and functions access from the ExVe interfaces for the purpose of developing services. Data and
functions of the vehicle are basic information that are key for the development of services for the vehicle
owner, driver, and user. Vehicle data and functions, in this context, comprises onboard, offboard or a
combination of the two.
This document, in conjunction with ISO 20077-1 and ISO 20077-2, describes the full process for the provision
of data and functions access from the ExVe interfaces between the SP and the VM.
All the situations where requested data and functions are dedicated to internal development and design
or product quality improvements from the VMs' and suppliers' side, when they are not acting as service
providers, are excluded from this document. Also, commercial aspects are out of the scope of this document.
