Folksonomy Engine

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 tags and 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.

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.

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 will add 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.

Social tagging

Social tagging can be introduced in different ways. Simpler forms as Hashtags or Text Tags or more complex ones as individual attributes in units.

Text Tags

There are many ways to implement social tagging inside of text, as simple plain keywords or more sophisticated forms with colors or different types of tags. The list of tags can be completely free for the user, predefined by admins or curated by admins.

Individual properties and attributes

Properties, or material facts, allowing to specify a value or multiple values for the corresponding product. Eg. it allows adding free properties with values.

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]
