ISO/TS 15638-11:2013 addresses the provision of ?Driver Work Records' and specifies the form and content of such data required to support such systems, and access methods (4.1) to that data.

ISO/TS 15638-11:2013 provides specifications (4.41) for common communications and data exchange aspects of the application service (4.3) driver work records that a regulator (4.37) may elect to require or support as an option, including:

a) high level definition of the service that a service provider (4.39) has to provide, (The service definition describes common service elements; but does not define the detail of how such an application service (4.3) is instantiated, not the acceptable value ranges of the data concepts defined)

b) means to realise the service

c) application data, naming content and quality that an IVS (4.22) has to deliver.

The definition of what comprises a 'regulated' service' is regarded as an issue for national decision, and may vary from jurisdiction (4.26) to jurisdiction. This document does not impose any requirements on nations in respect of which services for regulated vehicles jurisdictions will require, or support as an option, but provides standardised sets of requirements descriptions for identified services to enable cnsistent and cost efficient implementations where instantiated.

ISO 15638 has been developed for use in the context of regulated commercial freight vehicles (hereinafter referred to as ?regulated vehicles' (4.36). There is nothing, however, to prevent a jurisdiction extending or adapting the scope to include other types of regulated vehicles, as it deems appropriate.
