Digital Twin Description Framework (DTDF) Ontology

This work is based on [1], which aims to create a reporting framework for Digital Twins (DTs) from 21 characteristics. We build their ontology vocabulary and description in Onotlogy Modeling Language (OML) in openCAESAR Rosetta. We provide the example of an incubator (also described in [1]) for the OML description.

We use our separately-developed tool called DTInsight to generate an interactive conceptual architecture visualization of the DT based on this ontology. We call it a DT Constellation, and it is based on a previous paper [2]

We then generate a reporting page integrating the characteristics table and the conceptual architecture from a CI/CD pipeline. You can view it at https://oakeslabmtl.github.io/DTDF/.

OML vocabulary and description location

The DTDF vocabulary can be found under src/oml/bentleyjoakes.github.io/DTDF, and the incubator DTDF description under src/oml/bentleyjoakes.github.io/incubator
