This document provides an overview and the fundamental principles of the multipart standard ISO 23726 series Industrial automation systems and integration – Ontology based interoperability (OBI).
This document specifies the principles for ontologies and artefacts aligned with IDO upper ontology to be considered part of the OBI series.
This document is applicable for the representation of engineering data associated with all phases of the life cycle of industrial products, plants and systems to enable semantic interoperability.
The following are outside the scope of this document:
- specification of ontology languages.
- specification of Semantic Web standards such as Resource Description Framework (RDF), SHACL, SPARQL, and Internationalized Resource Identifiers (IRIs).
- specification of methods for reasoning with ontologies.
- methods to build, maintain, align, and evaluate ontologies and artefacts to meet the principles in this document. These will be covered in separate guideline documents.
