Introduction
DABGEO is a global ontology that provides a common knowledge representation of the energy data domains represented by the existing energy ontologies.
DABGEO has been developed to be reused by different energy management applications. These applications can be classified into five main application
types according to the Smart Grid scenario or infrastructure where they are deployed [1]: Smart Home energy management applications,
building/district/city energy management applications, organization energy management applications, microgrid energy management applications and
Smart Grid (DR) management applications. In addition, these application types encompass more specific application types. For instance,
within Smart Home energy management, there are applications that are focused on home energy assessment, home energy saving advice and
home appliances DR management [1].
In this way, DABGEO provides interoperability between energy management applications that operate in different scenarios.
The DABGEO ontology represents the following energy domains:
Energy equipment domain: data about energy equipment such as consumption systems (i.e., home appliances, Heating Ventilation and Air-Conditioning (HVAC) systems), renewable and non-renewable energy sources, (i.e., photovoltaics, fuel oils) and power storage devices (i.e., batteries). This domain includes data about energy equipment features and operational aspects such as device power profile or device state.
Infrastructure domain: different types of infrastructures and buildings (i.e., homes, industrial infrastructures, campuses, microgrids, power plants, etc.), building/infrastructure features (i.e., surface, material, etc.), geometrical details (rooms, floors, etc.) and internal and external environmental conditions (i.e., room temperature, etc.).
Energy performance data domain: energy performance values (energy production, consumption and storage values) of devices and infrastructures and energy Key Performance Indicators (KPIs) such as infrastructure energy cost or energy gain.
Energy external factors domain: data about external factors that may affect the energy usage. These factors include infrastructures location data (i.e., latitude and longitude, state, city), weather/climate data (weather conditions and weather forecast) environmental data (i.e., air pollutants and their indicators), and demography and socio-economic data (i.e., population density, population main origin, person education level).
Smart Grid stakeholders domain: data about Smart Grid stakeholders such as individual users (i.e., home users, building occupants, employees) and organizations (i.e., corporations, educational institutions). It also encompasses the Roles that Smart Grid stakeholders have in the energy market such as energy consumers, energy suppliers or Distribution System Operators (DSOs).
DABGEO ontology structure
Within the DABGEO ontology, the energy domains are divided into subdomains that cover the knowledge of important parts of the domain.
Figure 1 provides and overview of the DABGEO high-level structure, enumerating the subdomains in which the represented energy domains are classified.
Figure 1: DABGEO ontology high-level structure
The energy equipment domain encompasses the following subdomains:
Energy consumption systems subdomain: specific energy consumption devices such as domotic network components, HVAC systems, appliances, lighting systems and security system. It also includes operational aspects of these devices such as appliances working mode or field of application.
Distributed Energy Sources (DERs) subdomain: specific energy generation systems and energy storage systems, as well as their operational aspects.
Metering/actuation equipment subdomain: energy performance sensors, environmental sensors, building element sensors, building element actuators and device actuators. It also includes configuration and operational data about these devices.
Device operation data subdomain: operational aspects of any device such as device commands, device functionality and field of application, device state, device power profile, device flexibility data or user preferences.
The infrastructure domain encompasses the following subdomains:
Infrastructure structural data subdomain: structural aspects of infrastructures such as building geometry, building spaces or building orientation.
Infrastructure operation data subdomain: operational aspects of infrastructures such as external/internal environmental conditions or building energy performance requirements.
The energy performance data domain encompasses the following subdomains:
Energy usage data subdomain: energy usage values such as energy consumption/storage supply, energy usage forecast, energy cost or energy sources.
Energy key performance indicators subdomain: energy performance indicators that include renewable energy, energy efficiency or energy cost.
The energy external factors domain encompasses the following subdomains:
Weather data subdomain: weather phenomena, weather reports and climate types.
Environmental factors subdomain: air pollutants and weather-related environmental factors.
Socio-economic factors subdomain: household, population and person economic factors that can hinder energy performance such as population income data or home pricing.
Geographical factors subdomain: populated and natural places.
The Smart Grid stakeholder subdomain encompasses the following subdomains:
Individual actor data subdomain: individual energy actors (i.e., user, systems) as well as their main attributes (i.e., user preferences) or the actions they performed (i.e., energy saving discussions).
Organization data subdomain: organization internal structure (i.e., organization members, organization facilities) and organization operation (i.e., business processes, organization activities).
Energy market roles: the roles that energy actors have in the energy market (energy consumer, producer), the energy they provide and the infrastructures they own.
The knowledge of these subdomains is divided into ontology modules that represent the knowledge of a particular topic of the subdomain.
Specifically, the current release of DABGEO consists of 97 ontology modules in total. For example, within the energy consumption systems subdomain,
the ontology modules represent the knowledge about specific energy consumption systems such as refrigeration devices (refrigeration devices ontology)
or the knowledge about operational aspects of energy consumption systems such as appliance working modes (appliance working mode ontology).
If an ontology module extends or requires the knowledge of another module, the latter is included in the former.
The ontology modules of DABGEO are classified into three abstraction layers. These layers separate the common domain knowledge that is relevant almost all
Smart Grid scenarios from the variant domain knowledge that is relevant to certain Smart Grid scenarios. With this structure, ontology developers can select
the knowledge of DABGEO at the proper level of abstraction to develop application ontologies for energy management applications.
Details about each layer and the ontologies they contain can be found below.
Common-domain Layer
The common-domain layer represents the top-level concept of each domain in one ontology module. In the case of the energy equipment,
the top-level concept is Device, so the Device ontology module represents this concept as well as device main properties (i.e., device name).
In addition, this layer also includes the domain knowledge common to almost all Smart Grid scenarios (Smart Home energy management applications,
building/district/city energy management applications, organization energy management applications, microgrid energy management applications and Smart Grid
DR management applications). As this knowledge is relevant for many applications, only one ontology module includes the common knowledge of each subdomain.
The ontology modules that contain the common knowledge of each subdomain extend the knowledge of the top-level domain concepts. Therefore, these ontology
modules include the ontology modules that represent top-level domain concepts. For example, the energy consumption systems ontology module represents the
knowledge about devices that are relevant to almost all Smart Grid scenarios and application types such as home appliances or HVAC systems.
This module extend the knowledge about devices, so it includes the knowledge of the Device ontology module.
Device ontology: The 'Device' ontology module represents any device main information (i.e., name, code, etc.).

Apart from the listed ontology modules, DABGEO includes a ontology alignment file (in .owl format) that includes the equivalence relations between elements from existing energy ontologies. This file is used to provide interoperability between applications that use these ontologies.
Ontology Description Diagrams
The following diagrams resume the DABGEO ontology structure and ontology module dependencies in each energy domain.
It is worth mentioning that the ontology modules of one domain/subdomain may include the knowledge of ontology modules from other
domains/subdomains because they require this knowledge.
