Product Service System Ontology (PSS Ontology)
Version 2026-08-27
The IOF is an international standards group that operates under the auspices of the Open Applications Group.
Introduction
The PSS Ontology aims to support the software platforms being developed to support the product service systems’ from design to end of life
ProductServiceSystem.rdf imports IOF Core directly. BFO-2020.owl and IOF-AnnotationVocabulary.rdf are imported through IOF Core.
Release note
A basis ontology for enhancing engineering of Product Service System(s) (PSS) in manufacturing, by modelling all the aspects that affect, or could affect a PSS. This new ontology module is called ProductServiceSystem with IRI (https://spec.industrialontologies.org/ontology/productservicesystem/ProductServiceSystem/) is developed as a separate module within IOF. This ontology covers the basic constructs to model and connect PSS constituents: from product, service, involved agents, business organizations, (PSS and manufacturing) resources, and requirements, design and plan specifications, PSS business processes up to organization supporting entities such as product family and product variant set. This module is expected to mature in future release based on further analysis of use cases and user feedback. The current PSS module focuses on manufacturing industry, but the extention to other sectors will be analysed in the future.
The Product Service System set of ontologies was extended by a Sensor ontology module in the IOF 202603 release. The Sensor ontology module ensures that a basic set of entities to model Sensors and related classes is available, such as Sensor, Transducer, Detector, Sensing Function, etc. The ontology is currently in the draft stage and is as such labeled as Provisional.
