Introducing NeoWiki and More at MUDCon

Introducing NeoWiki (Spring 2026)

At the most recent MUDCon, I introduced NeoWiki, a new open-source MediaWiki extension for structured data. I co-presented with Bernhard Krabina from Knowledge Management Associates.

I have been maintaining Semantic MediaWiki for over 15 years and created large parts of Wikibase. Both are powerful, but they were designed in a different era. SMW is over 20 years old. Tools like Notion and Airtable have since set a usability standard that these older systems were never designed to match.

NeoWiki applies the lessons we have learned. You get radically better usability and sustainability, with a focus on the features that deliver the most value rather than feature parity. That means native schemas with types and constraints, form-based editing, multiple subjects per page, JSON storage in MediaWiki revision slots, and a standard graph database for queries.

NeoWiki is backed by ECHOLOT, an EU-funded cultural heritage consortium with 15 partners across 11 countries, and by Hallo Welt, the company behind BlueSpice. NeoWiki will power structured data in the next major version of BlueSpice. Professional Wiki is the product owner.

You can try NeoWiki at neowiki.dev and find the source on GitHub. The slides are available online. We will embed the recording here once it is published.

Follow NeoWiki on Mastodon, Bluesky, or X. Or visit the NeoWiki page to sign up for updates.

MediaWiki MCP Server (Fall 2025)

At MUDCon Fall 2025 in Hannover, I presented our MediaWiki MCP Server in a 20-minute talk. MCP (Model Context Protocol) is a standard that lets AI assistants interact with external tools and data sources. With our MCP Server, your AI assistant can read, create, edit, and delete wiki pages directly.

In the demo I showed creating pages, building tables, and deleting pages. The MediaWiki MCP Server is open source and available on GitHub.

Wikibase Extensions (Fall 2025)

Also at MUDCon Fall 2025, I gave a 20-minute overview of the Wikibase extension ecosystem. If you use Wikibase, these 17 extensions can give you advanced search, data validation, local media support, date handling, and automated property values.

We have a detailed write-up in our blog post Enhance Your Wikibase With Extensions.
