The primary purpose of ISO 15926 is to provide a foundation ontology to support the integration and sharing of data related to the lifecycle of a process plant in such a way that it is consistent, unambiguous, and minimizing the number of ways something could be expressed. Further purpose of ISO 15926-14 is to meet needs for OWL 2 ontologies that are based on ISO 15926-2, that enable efficient reasoning and that capture lifecycle information. A specific purpose is to demonstrate lifecycle modelling through a representation of the lifecycle model of ISO/IEC 81346-1. Another specific purpose is to exemplify how this standard can be used to develop industrial ontologies through various real-world use cases from industry.
