ISO 15143-2:2010

Overview

ISO 15143-2:2010 specifies a standardized data dictionary to support electronic worksite data exchange for earth‑moving machinery and mobile road construction machinery. As the second part of ISO 15143 (following Part 1: System architecture), this standard defines the identification, definition and metadata required for common data items exchanged on typical earth‑moving construction worksites. It provides a foundation for interoperable data exchange between machine control systems, telematics, fleet management and worksite IT systems.

Key topics and requirements

• Data dictionary structure: Composition and classification of the dictionary, including normative data element tables (Annex A) and the structure model (Annex B).
• Data element definitions: Identification and definition of data elements (DE) and data element concepts (DEC), following ISO/IEC 11179 metadata principles.
• Metadata attributes: Required metadata for each data element, such as name, definition, value domain, representation class, data origin, version and administrative status.
• Application schema: Definition of application scenarios and schema that illustrate how each data element is used on the worksite (Clause 5).
• Value domains and representation: Specification of value domains (permissible values) and representation classes to ensure consistent syntax and semantics across systems.
• Normative annexes: Tabular presentation of basic data elements and an informative application example for machine management (Annex C).

Practical applications and users

ISO 15143-2 is intended for organizations and professionals who need reliable, semantically consistent worksite data exchange:

• OEMs (machine manufacturers) - to publish machine telemetry and control data in a standard format.
• Telematics and fleet management providers - to integrate machine status, location and usage data.
• Construction contractors and site managers - to improve quality control, scheduling and coordination of operations.
• Software developers and system integrators - to design databases, APIs and applications that consume or produce standardized worksite data.
• Standards bodies and data modelers - to align metadata registries and domain ontologies with ISO/IEC 11179 practices.

Benefits include improved data sharing, clearer semantics for exchanged data, consistent database and software development, and better machine‑to‑system interoperability on construction worksites.
