The first CKAN Extensions Demo Day brought together developers and practitioners to showcase practical enhancements for CKAN-based data portals. Each extension directly addresses common operational challenges—improving usability, security, metadata management, and user interaction.
The first CKAN Extensions Demo Day brought together developers and practitioners to showcase practical enhancements for CKAN-based data portals. Each extension directly addresses common operational challenges—improving usability, security, metadata management, and user interaction.
Here’s a recap of the tools presented:
Presenter: Oleksandr Cherniavskyi (Link Digital)
ckanext-unfold adds the ability to preview archive files (ZIP, RAR, 7z, and others) directly within CKAN.
Key features:
This extension provides a much-needed update over older tools, especially for portals that store datasets as archives.
Presenter: Andrés Vázquez (Open Knowledge Foundation)
ckanext-push-errors improves monitoring by automatically sending unhandled errors and critical logs to specified endpoints (such as Slack or any HTTP server).
Key capabilities:
This extension is especially useful for managing CKAN instances where developers do not have continuous infrastructure access.
Presenter: Joel Natividad (datHere)
The new DRUF-enabled DataPusher Plus introduces automatic metadata suggestion during file uploads, supporting easier data ingestion and improved metadata quality.
Main features:
This helps streamline the metadata entry process, reducing manual work and improving dataset quality.
Presenter: Michael Polidori (Datopian)
ckanext-querytool enables the creation of interactive visualizations—charts, maps, and tables—directly within the CKAN user interface.
Capabilities:
It provides portal users with more ways to interact with datasets beyond simple downloads.
Presenter: Jesse Vickery (Open Government Canada)
ckanext-citeproc allows CKAN portals to generate formal citations for datasets and resources in multiple academic styles.
Key points:
This improves dataset credibility and facilitates citation in academic and professional publications.
Presenter: Thomas Hanke (Fraunhofer IWM)
ckanext-chat implements a chat interface powered by Pydantic-AI that allows users to query CKAN through natural language.
Main functions:
This extension lowers the technical barrier for interacting with CKAN and can assist in metadata management tasks.
The extensions presented during Demo Day Part 1 address practical needs encountered by open data publishers: from better file handling and real-time error monitoring, to easier metadata entry, improved visualization, and enhanced user interaction.
We look forward to seeing further developments and contributions at CKAN Extensions Demo Day – Part 2 on April 23, 2025.
