Folksonomy Engine

Folksonomy Engine

Summary

The goal of Folksonomy engine is to unleash an ocean of new usages regarding food knowledge. Folksonomy engine allows all kind of people — citizens, researchers, journalists, professionals, artists, communities, innovators... — to enrich and use Open Food Facts, thanks to free properties for your own use or to enrich the shared knowledge. Open Food Facts, as the biggest open-food database in the world, already feeds hundreds of data reuses. It will allow thousands of new apps and new usages.

Key dates and numbers

• 2022: Launched thanks to NLNet fund
• 2022: First beta (for moderators only)
• 2024-09: Beta opened to all registered users

Why it matters

For food products, it allows to create new kind of properties. Popular properties could join the official Open Food Facts model if they are often used.

For other products, Folksonomy Engine could be the base layer to create many different properties related to many different types of products. Eg. un smartphone have very different properties than a driller.

What we’ve done recently

• 2024: Fix small bugs.
• 2024-09: Opened to any registered users.

What we are currently working on

• 2024-09: start to work on better documentation
• 2024-09: creating new properties for Open Products Facts

What’s coming up next

• 2024-09: new home page

Description

Status: # Folksonomy Engine API is up and running.

1. Folksonomy Engine user interface is currently tested by Open Food Facts administrators. There is also a simpler interface that can be installed as a user script.

Use cases

1. ​ Health and food safety
2. ​ Cooking and preparation
3. Grocery Apps
4. Product qualities
5. (Bad) Food Marketing
   1. ​List properties of products targeting particular people
   2. ​List properties of products related to consumers behavior

See, some use cases we are starting to investigate.

We also have investigated separately mobile use cases, as they allow very different kind of things.

How

As of today, Open Food Facts is made of a set of predefined properties (about 20 types of properties such as the product name, the product weight, the ingredients, the nutrients, etc.). Folksonomy engine is adding several kinds of new individual data properties to Open Food Facts or Open Products Facts. In fact, the scope of such new data properties is nearly endless, so we intend to get feedback from the community to define which one we should implement and how the user interface should look like.

Properties, or material facts, allows to specify a value or multiple values for the corresponding product.

Example: This product height is 35 cm, which ends up in a tag like [height = 35cm].

Sometimes a property can have multiple values:

Example: This product has to be recalled if produced on 2020-03-31, 2020-04-01, 2020-04-02. [Recall: if produced from 2020-03-31 - 2020-04-02]

Wishful deliverables

Here we put wishful deliverables if any.

• Tool to monitor tag usages.
• Workshop for contributors.

Questions/ideas

• What about a deliverable dedicated to communication?
• Use case in collaboration with scientists?
