    dcterms:description "A vocabulary defined for Intelligent Transport Systems and documented as a formal ontology. The contents of this vocabulary are periodically standardized in ISO 14812, whereas this file is maintained through a [GitHub project](https://github.com/ISO-TC204/iso14812).  The original version of the vocabulary was published as [ISO/TS 14812:2022](https://www.iso.org/standard/79779.html). [Edition 2](https://www.iso.org/standard/85041.html) was released in 2025.  With edition 3, the draft standard is now generated from this ontology file, originally developed in 2026."@en ;
