A property, with an associated value, expresses the state or the behavior of a product. Eg. for the product 0523776898787 the color (property) is blue (the value).

In order to describe specific features of food products, we use tags consisting of two items, a '''''property''''' and a '''''value'''''. Both the property and the value are free format text fields, but often represent numeric or other structured items. Conventions are agreed on the meaning and use of properties and their values, which are captured on this wiki.

Open Food Facts allows any kind of users to create their own properties or reuse existing ones (see the [[Folksonomy Engine]] project).

Open Food Facts allows anyone to reuse existing properties or create new properties (see the [[Folksonomy Engine]] project).
