OEO Ontology

Overview

Open Energy Ontology

The Open Energy Ontology (OEO) is a dynamic domain ontology for energy system modeling, updated regularly following a release cycle.

Access the latest version 2.5.0 here.

Domain ontology: What is that?

An ontology is a structured collection of terms and their relationships, providing clear definitions and logical interpretation. The OEO aims to create a common language for energy system modeling, bridging various disciplines.

Standardising Terminology

Provides a controlled vocabulary with clear definitions, disambiguating terms

Data Annotation and Integration

Enhances data integration, aggregation, and search functions

Templates for Data Capture

Ensures uniform and detailed reporting structures

Visualisation

Makes complex knowledge comprehensible through various visual formats

Text and Data Mining

Automates searches across resources, aiding discovery, data synthesis, and meta-analysis

Modules

OEO Extended (OEOX)

To increase the usability of OEO and react to user requirements, we introduced a post-coordination extension to OEO, the Open Energy Ontology Extended (OEOX). We created OEOX as an ontology for specific energy- related terms with a high complexity that go beyond the level of detail of the standard OEO class hierarchy. For further information you can have a look at the GitHub page.

Usage beyond the Open Energy Family tools

The OEO is developed within the scope of the Open Energy Family but aims to serve the entire energy system modeling community. We encourage its use in various contexts and use cases beyond its initial scope.

Where and how can I contribute?

We welcome everyone to contribute to OEO development, a community-driven project hosted on GitHub. Explore our ontology course and have a look at our contribution guidelines. If you have questions, reach out via the OEP contact form, and we'll connect you with the right person.

Further information

OEO development began with the "SzenarienDB" project and is enhanced by "LOD_GEOSS", "SEDOS", "Stadt-Land-Energie" and "SIROP". The OEO was introduced in an open-access peer-reviewed paper: Introducing the Open Energy Ontology: Enhancing data interpretation and interfacing in energy systems analysis.

The OEO steering committee was established in autumn 2019.
