The Northwind Knowledge Graph has a permanent home. After five years of touring across triple stores, reasoning engines, and cloud platforms, the entire Northwind series now lives inside RDF Studio — ontology, data, SHACL shapes, 90 executable queries, and the articles themselves, all in one place.
The Northwind Knowledge Graph began as a simple idea: take the database every developer already knows — the classic Northwind trading company — and use it to teach RDF and SPARQL to people coming from a relational background. Learning by example, side by side with the SQL they already understood.
That idea turned into a series. Over the years, the Northwind KG ran in many places — across triple stores, reasoning engines, and cloud platforms:
Each article was a great destination — but every one of them asked the reader to get there first. Stand up a triple store. Load the data. Install a notebook environment. Provision a cloud cluster. Copy the queries out of the article and paste them into a separate tool. The knowledge graph was excellent; the on-ramp was the hard part.
The Northwind KG was always meant to be picked up and used, not just read about. But a knowledge graph scattered across blog posts, GitHub folders, and a different tool per article is a knowledge graph you have to reassemble every time.
RDF Studio changes that. The Northwind Knowledge Graph is no longer something you download and wire up — it's something you open. The ontology, the instance data, the SHACL shapes, the reasoning rules, and every query from the article series ship inside the app, ready to run against a private database that's yours alone.
No installation. No cluster. No copy-paste. Connect to Northwind and everything the articles describe is already there, executable with one click.
The Northwind Knowledge Graph in RDF Studio is the most complete version it has ever been — a full semantic-web training environment built on the familiar trading-company domain:
Every query is explained and executable. The reasoning rules are no longer a thought experiment in a blog post — they run. The named-graph patterns are no longer screenshots — you can write your own.
Northwind doesn't just live in RDF Studio — it lives inside a full semantic workspace. Everything the articles used to need a separate tool for is now one tab away:
Prefer to watch first? The "See it in Action" videos on the home page show each of these in under a minute.
The series didn't just get a place to run — it moved in. The full Northwind article collection is available under Learn → Articles, readable inside RDF Studio without opening a browser tab. And the queries those articles walk through aren't trapped in code blocks anymore: they live in the Query Library, one click from execution against your own Northwind database.
Read an article, find the query it describes in the Library, run it, change it, and watch the graph respond — all in the same window. That's the difference between reading about a knowledge graph and working with one.
The Northwind Knowledge Graph is ready the moment you open RDF Studio:
The knowledge graph that taught a generation of developers SPARQL across half a dozen tools now has one address. Welcome home, Northwind.
