Digital Twin ontology used to define Digital Twins and Semantic Digital Twins and aggregations by dimensions using Web of Things.
WoTDT: The WoT Digital Twin Ontology with Aggregation extension.

Existing connection between different dtw:ConnectionPoint.
Connection
Connection point of the connection.
Connection Point
Connection between dcat:Resource and td:InteractionAffordance.

This dimension of the digital twin consists of various data models that represents all the information allocated in the digital twin.
Digital Entity
1
1
1
A realistic representation of all product life cycle components using physical, virtual and interaction data.
Digital Twin
Describes the aggregation of all the DTIs. Unlike the DTI, the DTA may not be an independent data structure. It may be a computing construct that has access to all DTIs and queries them either ad-hoc or proactively.
Digital Twin Aggregate
Dimensions of which the digital twin is composed.
Digital Twin Dimension
Describes a specific corresponding physical product that an individual Digital Twin remains linked to throughout the life of that physical product.
Digital Twin Instance
This dimension of the digital twin consists of various subsystems, objects and sensory devices. These subsystems can include dynamic systems, control systems, maintenance systems, etc., and can be combined for a specific task. Also, non physical entities can be represented.
Entity
Connection point of the connection that is external to the DTw.
External Connection Point
Extension format in which the model or data is available.
Format
Describes all the geometric parameters of the physical entity (e.g. shapes, sizes and assembly relations).
Geometric Model
Connection point of the connection that is internal to the DTw.
Internal Connection Point
Model that allows the alignment of data with the objective of obtaining harmonised data from non-harmonised data.
Mapping Model
1
Representation or conceptualization of the data registered in the Virtual Entity dimension.
Model
Connection between dtw:Model and dcat:Resource.
Model Data Connection
Model Model Connection
Connection between dtw:Model and td:InteractionAffordance.
Model Service Connection
Model that contains the conceptualization of the information of the digital twin. This conceptualization activity refers to the organization and structuration of the information (data, knowledge, etc.), obtained during the acquisition process, into meaningful models at the knowledge level and according to the ontology requirements specification document.
Ontology Model
Responsible for providing all the physical properties (e.g. speed and force) based on dt:GeometricModel
Physical Model
A set of rules extracted from the historical data obtained from the physical model, whose function is to provide the virtual entity with a judgment for decision making, optimization, evaluation, prediction and maintenance.
Rules Model
Semantic Model
Model that contains the data validation rules allowing the data to be validated.
