Finally, SSEN is committed to supporting the transition towards a sustainable energy future, which aligns with broader environmental goals.

The criteria

User Accessibility and Experience

  • The portal should be built on a CKAN-based framework to ensure a user-friendly experience.
  • The front-end platform must support public users. Management actions can be done via the CKAN backend interface.

Data Types and Formats

  • Geospatial Data Support: Essential for providing location-based data, the portal must handle geospatial data formats like GeoJSON and Shapefiles.
  • Single-Point Access: The portal should serve as a unified access point for all datasets or data assets published by SSEN, thereby increasing transparency and accountability.

Data Catalog

  • Comprehensive Catalog: The portal needs to offer a thorough catalog of data that includes details about network assets, their location, utilization, and performance metrics.


  • Beyond conventional datasets, the portal should offer "Insights," a category of special data assets accompanied by associated visualizations or Power BI reports. These Insights should be crafted to be shared widely and may originate either from a published dataset or table or stand alone without the underpinning data, when aggregated or summarized data is used to support data classification and enable access to data consumers.

Standard Metadata

  • Metadata Standard: The portal should have Dublin Core (also known as the Dublin Core Metadata Element Set or DCMES) and DCAT metadata standards to ensure consistent and standardized metadata descriptions for all data assets within the portal.
  • Seamless Portal Interoperability: The portal should support interoperability with various external applications and systems following the Dublin Core and DCAT metadata specifications.

Privacy and Sensitivity

  • Some insights may be built without displaying the underlying raw data to protect sensitive information.
"Data assets, not datasets!"

This encapsulates SSEN’s emphasis on treating data as a valuable asset, rather than just raw datasets.

The solution


In alignment with its objective to offer a user-friendly, centralized source of data, SSEN has selected CKAN for their Data Portal. Leveraging PortalJS and CKAN we've created an intuitive, scalable, and dynamic platform that enhances the data accessibility and management experience for both users and administrators.

Geospatial Data

Special attention has been given to the integration of geospatial data assets, including GeoJSON and Shapefiles. This focused approach avoids confusing users with irrelevant maps or broad reports, aligning instead with the expectation for precise spatial data—crucial for understanding SSEN's network assets, usage patterns, and performance metrics.

User-Centric Frontend Design

Our design ethos prioritizes user engagement and navigation. SSEN opted for an aesthetically pleasing front end, featuring a sophisticated color palette aligning with the SSEN brand, ensuring customer familiarity. This design not only ensures visual appeal but also enhances user navigation and engagement on the portal.

Customization, Adaptability, and Extensibility

The front end is highly adaptable, empowering SSEN to customize the platform according to evolving requirements. With the flexibility offered by PortalJS, SSEN has the agility to continuously update features, ensuring it remains a dynamic and responsive part of their data management ecosystem.

Metadata standards

The indispensability of standardized metadata in data portals cannot be overstated. It serves as a universal language for describing and organizing data assets. Metadata standards such as “Dublin Core”, and “DCAT” ensure that data descriptions are clear and understandable for everyone, preventing confusion and enabling seamless integration with various external applications and systems.

Some of the metadata required for the SSEN project was not readily available in CKAN out of the box. Therefore, custom metadata was incorporated to fulfill the requirements. Implementing a CKAN DCAT extension enables access to DCAT standard metadata via a dedicated URL. However, the SSEN project also requires Dublin Core metadata, so the extension has been customized to support it. As a result, the portal now seamlessly supports both Dublin Core and DCAT metadata, facilitating smooth data integration across various applications, in alignment with the Icebreaker One guidance on Dublin Core and DCAT crosswalk.
