Ontology for materials database interoperability, structure-classification, simulation models, and physical properties.

Submodule ontology representing components and materials assemblies inside a Digital Product Passport (DPP)., This is an ontology module focusing on the composition information of products.

Submodule ontology representing informational metadata properties of a Digital Product Passport (DPP)., This is a minimal core ontology describing DPP information types.

Submodule ontology representing provenance and lifecycle event tracking inside a Digital Product Passport (DPP)., Provenance information for DPP information.

An ontology for Digital Product Passports in the Architecture, Engineering, and Construction (AEC) industry.

Example of SMART content are Provisions such as Requirement, Recommendation, Permission

Allotrope Foundation Ontology (AFO) represents lab equipment, processes, measurements, and analytical chemistry vocabulary.

Ontology for laser-plasma physics and its applications, maintained by the Computational Radiation Physics community.

The Open Energy Ontology is a domain ontology for energy-system analysis, developed by the Open Energy Ontology community., The Open Energy Ontology is an ontology for all aspects of the energy modelling domain. It is developed in four main modules: 'oeo-model', a module for all entities related to models and modelling; 'oeo-physical', a module for all entities related to the world of energy and energy generation; 'oeo-social', a module for all relevant social and economic aspects of the energy domain; 'oeo-shared', a module to cover entities and relations needed in all of the modules above to prevent them getting implemented multiple times. A supplementary module is the oeo-physical-axioms module, which contains general class axioms.

Fraunhofer ICGV AM Application Ontology is an ODE_AM application module for additive-manufacturing data management. It reuses BFO as top-level and CCO as mid-level ontologies, imports the IGCV Manufacturing Application Ontology, and adds AM-specific concepts such as process parameters, build-platform coordinates, support structures, machine entities, and instruction-file artifacts for consistent process documentation and querying.
