ISO 14817-2:2015

Overview - ISO 14817-2:2015 (Governance of the CIDCR)

ISO 14817-2:2015 defines the governance and registration process for the Central ITS Data Concept Registry (CIDCR) used in Intelligent Transport Systems (ITS). It specifies how ITS data concepts that conform to ISO 14817‑1 are entered, managed and maintained in the CIDCR to maximize interoperability and minimize duplicate or inconsistent data definitions across ITS applications. The standard supports migration of data concepts from application-specific data dictionaries and is compatible with data derived from the ISO 14813 ITS system architecture or alternative international, regional or national architecture methodologies.

Key technical topics and requirements

• Registration framework and concept of operations
  • Rules for entering ITS data concepts into the CIDCR and how those concepts relate to interface dialogues and system architectures.
• Governance roles and responsibilities
  • Defined actors such as the ITS executive committee, change control committee, Registration Authority, Registrar, Steward, Submitter, and read-only users, with responsibilities for approval, change control and stewardship.
• Administrative meta-attributes
  • Mandatory and optional administrative metadata (e.g., create date, revision date, submitter, steward, owner, quality, status, follower, comment, harmonization candidate) to support traceability and lifecycle control.
• Quality control and status/version management
  • Annexes that address quality control processes, status levels and version control to ensure registry integrity and evolution.
• Harmonization and resolution
  • Procedures for identifying harmonization candidates and resolving duplicate or conflicting data concepts across stakeholder groups.

Practical applications and users

Who uses ISO 14817-2:

• ITS application developers and system integrators to ensure consistent data element definitions across interfaces.
• Equipment and service providers to align data exchanges with global ITS data concepts.
• Registry managers and stewards responsible for maintaining CIDCR entries, versioning and change control.
• National and regional ITS authorities to harmonize local implementations with international data concepts. Practical uses:
• Standardizing key data elements for traffic management, traveler information and vehicle-to-infrastructure interfaces.
• Documenting and registering interface dialogues to enable cross-domain reuse and interoperability.
• Migrating data dictionaries from CASE tools or national systems into an internationally governed CIDCR.

Related standards and context

• ISO 14817-1 - Requirements for ITS data definitions (complementary)
• ISO 14817-3 - Object identifier assignments for ITS data concepts
• ISO 14813 - ITS system architecture (reference for deriving CIDCR concepts)
• Developed by ISO/TC 204 (Intelligent transport systems)

ISO 14817-2 is essential for organizations aiming to improve ITS data interoperability, enforce consistent metadata practices, and govern a central registry of ITS data concepts (CIDCR).
