This standard specifies system architecture for the exchange of data related to the use of earth-moving machinery, as defined in ISO 6165, and mobile road construction machinery, as defined in ISO 22242 when used for work similar to earth-moving, in worksite data-controlled construction operations. It also gives definitions of terms related to worksite data exchange. It covers only the application layer of the OSI reference model according to ISO/IEC 7498-1, and does not cover the presentation, session, transport, network, data link or physical layers of the model. Specific agreement (selection of applicable specifications, standards, etc.) relating to those layers will therefore be needed if data exchange is to be facilitated
