How Eliona Covers Ontologies
Introduction
Eliona is a versatile and scalable platform that integrates ontologies such as Brick, Haystack, and RealEstateCore to enable efficient and user-friendly management of smart buildings. With its powerful features and an intuitive user interface, Eliona supports the structuring, integration, and management of building data in a way that promotes both flexibility and efficiency. This documentation provides a comprehensive overview of Eliona's structure and functions, including the use of tag systems, the creation of custom classes (asset templates), the geographical and functional nesting of assets, as well as advanced asset functions and data integration methods. By combining practical solutions with innovative technologies, Eliona ensures that smart buildings can be managed optimally and continuously developed.
Eliona's Structure
Eliona is a flexible and scalable platform that uses various building blocks from ontologies like Brick, Haystack, and RealEstateCore. Here is a general and clear overview of how Eliona is structured:
Eliona uses a tag system similar to Haystack. Tags can be assigned to easily identify and organize data points, devices, and assets. These tags can be used in many ways:
Rules for alarms and escalations: Tags can be used to define rules for alarms and escalations.
Access rights: Tags determine which users have which rights to which assets. User roles can also be assigned tags to regulate access.
Custom Classes (Asset Templates)
Eliona offers the possibility to create custom classes (Asset Templates) and give them attributes. The templates can represent anything from rooms and buildings to specific types of sensors or abstract concepts. Users can create their own templates (classes) and define which attributes they have and even create new attributes that are calculated from others.
Instances (Assets)
The created templates are implemented in concrete instances (assets). For example:
Room 001
Heat Sensor 001
These instances can also be assigned tags, which can then be used for various purposes.
Assets can be nested geographically and/or functionally by dragging and dropping them into one another. For example:
Sensor Temp 001 can be nested in Room 001.
Room 001 can be nested in Building A.
Extended Asset Functions
Similar to Brick, assets in Eliona can have various points:
Data Integration and Drag-and-Drop Formats
Eliona enables the quick creation of formats via drag-and-drop that integrate incoming data into an asset. These formats can be used to integrate data into the asset attributes, such as a temperature measurement, when connecting to MQTT, webhooks, RESTful, Kafka, UPD, UA, Modbus, and legacy systems.
App Store and Scalability
Eliona offers an app store where apps can be created efficiently that also support other connections to the platform. All data is stored in a PostgreSQL database, which ensures high scalability and efficiency. Eliona is a web application.
Interoperability and Bulk Import
Interoperability can be provided by an app as an interface. But there is also the option of bulk import, where data can be imported in JSON format. An API connection also enables the integration of data into the platform.
Eliona has a ticketing system in which tags can be used and assets can be assigned.
Use of AKS
In the geo-information (GAI) of an asset, AKS can be used to convey deep information at a glance in a string.
Eliona and the Use of Ontologies
Brick
Components of Brick in Eliona:
Points: Eliona integrates the concept of "Points" from Brick to organize various data points and measured values. These points can represent sensor values, statuses of devices, or other relevant information.
Nesting of Assets: Eliona enables the geographical and functional nesting of assets, similar to how Brick structures rooms, zones, and buildings.
Asset Attributes: The attributes of the assets in Eliona are inspired by the detailed and specific attributes that Brick defines for various building objects.
Advantages of using Brick:
Structured data organization: The clear structure of Brick facilitates the organization and management of building data.
Easy navigation and visualization: The nesting of assets enables intuitive navigation and visualization of the building structure and its components.
Expandability: The use of points and attributes allows for flexible expansion and adaptation to specific requirements.
Haystack
Components of Haystack in Eliona:
Tag system: Eliona adopts the tagging system from Haystack, which makes it possible to assign tags to easily identify and organize data points, devices, and assets.

Rule-based automation: By using tags, rules for alarms and escalations can be defined in Eliona, which enables an automated response to certain events.
Advantages of using Haystack:
Simplicity and flexibility: The tagging system facilitates the identification and organization of data without complex hierarchies.
Efficient data integration: The flexible structure of Haystack enables the quick integration and processing of data from various sources.
Automation: Rule-based automation improves the responsiveness and efficiency of building management.
Managing user rights: Tags can be used to control users' access rights to various assets.
RealEstateCore
Components of RealEstateCore in Eliona:
Classes and Instances: Eliona uses the concept of classes and instances from RealEstateCore to create specific asset templates that can then be implemented in concrete instances.
Users (Agents): Similar to how RealEstateCore uses the concept of agents to define different users and their roles, Eliona offers a flexible system for managing user roles and access rights.
Interoperability: Eliona uses the interoperability standards of RealEstateCore to facilitate communication and integration between different systems.
Advantages of using RealEstateCore:
Standardization: The standardized terminology ensures consistency and clarity in data management.
Interoperability: The use of interoperability standards facilitates integration and communication between different systems and platforms.
