Ontology Specification Draft

Abstract

Product Digital Twin Ontology (PDTO) is an ontology for representing the information of Product Digital Twins and Digital Product Passports (DPP). This ontology can be used to enable conversion between Asset Administration Shell (AAS) information models and knowledge graphs dedicated to DPPs.

Introduction back to ToC

PDTO (Product Digital Twin Ontology) is an ontology developed in 2025 by CEA DRT/LIST/DILS/LSEA. This ontology provides classes and properties that enable users to model information of Product Digital Twins (PDT) and Digital Product Passports (DPP). This online document is the specification of the PDTO version 0.9.3. The latest update is 25/03/2026.

Product or servicec back to ToC or Class ToC

IRI: http://purl.org/goodrelations/v1#ProductOrService

The superclass of all classes describing products or services types, either by nature or purpose. Examples for such subclasses are "TV set", "vacuum cleaner", etc. An instance of this class can be either an actual product or service (gr:Individual), a placeholder instance for unknown instances of a mass-produced commodity (gr:SomeItems), or a model / prototype specification (gr:ProductOrServiceModel). When in doubt, use gr:SomeItems. Examples: a) MyCellphone123, i.e. my personal, tangible cell phone (gr:Individual) b) Siemens1234, i.e. the Siemens cell phone make and model 1234 (gr:ProductOrServiceModel) c) dummyCellPhone123 as a placeholder for actual instances of a certain kind of cell phones (gr:SomeItems) Note: Your first choice for specializations of gr:ProductOrService should be http://www.productontology.org. Compatibility with schema.org: This class is (approximately) equivalent to http://schema.org/Product.
Is defined by
http://purl.org/goodrelations/v1
is equivalent to
Product c
has sub-classes
Product or service model c

Product or service modelc back to ToC or Class ToC

IRI: http://purl.org/goodrelations/v1#ProductOrServiceModel

A product or service model is a intangible entity that specifies some characteristics of a group of similar, usually mass-produced products, in the sense of a prototype. In case of mass-produced products, there exists a relation gr:hasMakeAndModel between the actual product or service (gr:Individual or gr:SomeItems) and the prototype (gr:ProductOrServiceModel). GoodRelations treats product or service models as "prototypes" instead of a completely separate kind of entities, because this allows using the same domain-specific properties (e.g. gr:weight) for describing makes and models and for describing actual products. Examples: Ford T, Volkswagen Golf, Sony Ericsson W123 cell phone Note: An actual product or service (gr:Individual) by default shares the features of its model (e.g. the weight). However, this requires non-standard reasoning. See http://wiki.goodrelations-vocabulary.org/Axioms for respective rule sets. Compatibility with schema.org: This class is (approximately) a subclass of http://schema.org/Product.

IRI: http://purl.org/goodrelations/v1#hasMPN

The Manufacturer Part Number or MPN is a unique identifier for a product, service, or bundle from the perspective of a particular manufacturer. MPNs can be assigned to products or product datasheets, or bundles. Accordingly, the domain of this property is the union of gr:ProductOrService (the common superclass of goods and datasheets), and gr:Offering. Important: Be careful when assuming two products or services instances or offering instances to be identical based on the MPN. Since MPNs are unique only for the same gr:BusinessEntity, this holds only when the two MPN values refer to the same gr:BusinessEntity. Such can be done by taking into account the provenance of the data. Usually, the properties gr:hasEAN_UCC-13 and gr:hasGTIN-14 are much more reliable identifiers, because they are globally unique.

has Stock Keeping Unit (0..*)dp back to ToC or Data Property ToC

IRI: http://purl.org/goodrelations/v1#hasStockKeepingUnit

The Stock Keeping Unit, or SKU is a unique identifier for a product, service, or bundle from the perspective of a particular supplier, i.e. SKUs are mostly assigned and serialized at the merchant level. Examples of SKUs are the ordering or parts numbers used by a particular Web shop or catalog. Consequently, the domain of gr:hasStockKeepingUnit is the union of the classes gr:Offering and gr:ProductOrService. If attached to a gr:Offering, the SKU will usually reflect a merchant-specific identifier, i.e. one valid only for that particular retailer or shop. If attached to a gr:ProductOrServiceModel, the SKU can reflect either the identifier used by the merchant or the part number used by the official manufacturer of that part. For the latter, gr:hasMPN is a better choice. Important: Be careful when assuming two products or services instances or offering instances to be identical based on the SKU. Since SKUs are unique only for the same gr:BusinessEntity, this can be assumed only when you are sure that the two SKU values refer to the same business entity. Such can be done by taking into account the provenance of the data. As long as instances of gr:Offering are concerned, you can also check that the offerings are being offered by the same gr:Business Entity. Usually, the properties gr:hasEAN_UCC-13 and gr:hasGTIN-14 are much more reliable identifiers, because they are globally unique. See also http://en.wikipedia.org/wiki/Stock_Keeping_Unit.

Description dp "A unit of mass in the metric system. The name comes from the Greek gramma, a small weight identified in later Roman and Byzantine times with the Latin scripulum or scruple (the English scruple is equal to about 1.3 grams). The gram was originally defined to be the mass of one cubic centimeter of pure water, but to provide precise standards it was necessary to construct physical objects of specified mass. One gram is now defined to be 1/1000 of the mass of the standard kilogram, a platinum-iridium bar carefully guarded by the International Bureau of Weights and Measures in Paris for more than a century. (The kilogram, rather than the gram, is considered the base unit of mass in the SI.) The gram is a small mass, equal to about 15.432 grains or 0.035 273 966 ounce. "^^H T M L
