This standard specifies a data dictionary for the exchange of data in worksite data-controlled construction operations as specified in ISO 15143-1. It also gives definitions of terms used in relation to the data dictionary. For the purposes of data exchange between different systems, it includes identification, definition and specification of common items of data to be exchanged on typical earth-moving construction worksites, definition of application schema, metadata describing the attributes of each data element, and basic normative data elements with their attributes (in tabular format).
