Architecture Map

French-spoken version with French and English subtitles. This video presents the architecture of the PROSIM database (PROduct SIMilarity) which compares products from the collaborative, free and open database of food products from around the world ( http://world.openfoodfacts.org ). PROSIM is built with Mongo running on a server, and can be queried using its dedicated API . The Tuttifrutti website ( https://tuttifrutti.alwaysdata.net ) uses this API for showing data in a graph with the following available scores: Nutriscore Nova Classification Scores are directly computed and delivered by OpenFoodFacts. The computation for the similarity between 2 products and their score is provided by a file called ComputingInstance.java (1 file per score) whose code is accessible here: Nutriscore Nova Classification

How can I request a new Score database created on my own?

The PROSIM Engine makes it possible to end-users like you to create your own OpenFoodFacts scoring database and to use it live in the OFF-graph website and App. Once you have submitted your Computing Instance file (see below) and after its validation by Admins, you will shortly be able to perform the following tasks with your own database: [A] seeing my database's stats-record in the PROSIM blog now available [B] seeing statistics of my database (size, progression, number of intersections computed, etc.) now available [c] querying my database using the API now available [D] querying my own database by scanning the barcode of a product and getting matching-results in a OFF-graph available on the test environment (clear Browser-Cache!) What do I need? Knowledge
