ChangingGraph
How does ChangingGraph work?
Explained simply — this page is for everyone, not just developers. If you prefer the technical view: For Developers →
Imagine you know someone.
Who knows someone with an organic farm.
The organic farm supplies a community-supported farm.
The community-supported farm is right near you.
In the real world: How would you
ever know?
With ChangingGraph: These
connections become visible.
What is a knowledge graph?
A knowledge graph is like a spider's web.
A spider builds its web. Every point is connected to other
points.
Touch one point, and the spider feels it everywhere in the
web.
ChangingGraph works the same way:
Every piece of information is a point:
- An organic farm
- A food item
- An initiative
- A person
And between these points there are connections:
- The organic farm produces potatoes
- The community-supported farm buys from the organic farm
- You are looking for regional vegetables
The web makes the connections visible.
What does that mean for you?
Scenario 1: Cooking regional and seasonal
Your question:
"What regional, seasonal, organic food can I cook next
week?"
ChangingGraph shows:
- Which vegetables are in season right now?
- Which organic farms near you have them?
- Which recipes can you cook with them?
And in winter?
ChangingGraph shows initiatives and people who share
their know-how:
- Preserving vegetables together
- Making jam
- Learning to ferment
- Building up winter stocks
Scenario 2: Finding initiatives
Your questions:
"Is there a food co-op near me?"
"Where can I get my broken coffee machine repaired?"
"Who around here is interested in permaculture?"
ChangingGraph shows:
- The repair café in your town
- The community-supported farm two villages over
- The local food co-op
- People looking for the same things
Not because they have big advertising budgets.
But because the connections are there.
Scenario 3: Sharing and trading
You want to:
- Share tools with neighbors
- Trade fruit from your tree for eggs
- Find someone to help in the garden
ChangingGraph connects:
- People who want to trade
- Initiatives that organize
- Neighbors looking for the same
Not Amazon. Not corporations.
But the people right around the corner.
Why is this different from other apps?
Many apps show individual things:
One app shows where the nearest organic store is.
Another app counts calories and nutrients.
Yet another shows recipes.
ChangingGraph shows the story behind them:
Not just "Where is an organic store?"
But:
- Which farmer supplies it?
- Which initiative is behind it?
- Which people are involved there?
- What connects you to them?
That's the difference:
Not just data. But connections.
How does the web emerge?
Step by step.
What is running prototypically today:
- Food data from the German national food database (Bundeslebensmittelschlüssel / BLS)
- Enriched with ingredient links to Wikidata and other sources
- Building the foundational web
What's coming:
- Capturing recipes and dishes
- Nutrition and symptom diary
- Newsletter and blog for exchange
- Tools that let end users create data connections themselves
- For example: "Product XY on OpenFoodFacts is the same as food item Z in BLS"
The web is growing.
With every piece of information. With every
initiative. With everyone who joins in.
How does it work technically?
Behind ChangingGraph are open standards: knowledge graphs (RDF), the Fediverse (ActivityPub) and semantic taxonomies (SKOS). That means the data doesn't belong to anyone alone — and that different systems can talk to each other.
