Industrial automation systems and integration. Integration of life-cycle data for process plants including oil and gas production facilities. Implementation methods for the integration of distributed systems: Web Ontology Language (OWL) implementation | Status: Current

1 Scope This part of ISO 15926 specifies implementation methods for integration, sharing, exchange, and handover of life-cycle information about process plants, based on the data model of ISO 15926‑2 and the template methodology of ISO/TS 15926‑7. The following are within the scope of this part of ISO 15926:

• — defining rules for applying RDF and OWL in the context of this part of ISO 15926;
• — mapping of the data model of ISO 15926‑2 from its EXPRESS format to OWL-2;
• — defining a methodology for creating an OWLontology for the ISO/TS 15926‑4reference data;
• — defining an OWLontology based on the base templates and the initial set of core templates;
• — defining a methodology for creating an OWLontology for "specialized templates" (see 2.1.32) that defines the types of information for any given instance of possible_individual during its lifetime.

The following are outside the scope of this part of ISO 15926:

• — the specific type of rule language used to implement the first order logic;
• — the decision as to whether data storage and exchange is done using lifted data or by use of lowered templateinstances and objects only.

NOTE This is a business decision.
