Product completeness
One of the goals of Open Food Facts is the ability to enhance the information provided by producers on their product packaging (readability, understandability, enhancement). What Open Food Facts will be able to do depends on the information provided on the packaging. This information starts with minimally legally required information to full transparency on supply chain and production processes.
The information available on the packaging must be extracted to the OFF-database and be transcribed correctly. Having the correct information is assessed by various the data quality approaches (insert link here).
The main enhancement that OFF currently, as of 19 February 2024, performs are:
- Nutriscore calculation, which requires nutritional information and some categorisation;
- Ultraprocessing assessment (NOVA), which requires ingredients;
- Diet suitability assessment, which requires in ingredients, traces and labels;
- Environmental impact, which requires information categorisation, supply chain information and production processes (in the experimental phase);
When OFF is able to make all these assessments for a product, it means that all necessary information was available. The product information would have complete. Whether this will be the case depends a lot on the producer in providing this information (full transparency).
Completeness
OFF strives to have complete information, i.e. have all information available on the package. As providing some information is optional, the concept completeness is limited to legally required information. The non-optional information falls under the heading transparency.
The most important information fields that OFF wants to have are:
- ingredients
- nutritional values
- product category (limited)
The system tracks whether these fields are filled in, using these status:
- ingredients completed and ingredients to be completed;
- nutrition facts completed and nutrition facts to be completed;
- categories completed and categories to be completed;
== Visualisation The completeness can be visualised with a pie chart, either for each field or all fields combined.
