=== Improve the UX of the native iOS app (Food Viewer) ===
=== Improve the UX of the native iOS app (Food Viewer) ===
As opposed to the other 2 mobile applications, the native iOS application contains full viewing and editing capabilities. However, the UX of this application is not as good as the other two. The work needed on this application is a presentation work, to put things in a form easy to use.

=== Define a proper clean API (new version) ===
=== Define a proper clean API (new version) ===
The current REST API of the Open Food Facts database was built with time and can be improved from the point of view of its completitude, consistency and error management. This proposal is about defining and implementing a new API, thought from scratch and but learning from the lessons of the previos experience. Solutions like Swagger can be envisaged to create a self documenting API and automatic bindings for various programming languages, but the proposal is not limited to this.

Currently, we use a wiki based system for taxonomies, that we have to reload. This is error prone and requires maintenance work.

Many core concepts of the Open Food Facts environment are organized as taxonomies (multilanguage categories of products, additives, etc).

Food and cosmetics change over time. Nutrition info, ingredients sometimes slightly change. Our contributors are here to document all that using photos, and then update the product.

Product Opener already stores basic changes, but once a product is edited, we can't see how it evolved over time. It would be tremendously interesting for nutrition science and contributors to be able to see how (positive) change happens over time.<br><br>

We currently have a very basic system to bulk-import images and create products accordingly.

...
Sometimes, the same error can sneak into a massive amount of contribution, for example related to a typo or a misunderstanding on an information on the packaging. In other situations, similar products might need to be updated in a similar way, for example filling in the type of packaging for all products of a same brand. This proposal is about creating a tool that would allow a moderator to easily select the products and perform these bulk changes on the selected products.

=== Re-work gamification and make it an important part of the User experience ===
=== Re-work gamification and make it an important part of the User experience ===
...
Currently there is a basic gamification system in Open Food Facts, giving badges to contributors based on their amount and type of contributions. However, this system is not receiving the attention it should, from a developement point of view, and the concept is not exploited to the maximum of its capabilities. As Open Food Facts relies on contributions from users, gamification can be used to improve retention of users, boost their contributions and increase the quality. Also, it can be used as a tool to drive the contributions in a direction that would not be followed naturally by the users but which is very valuable for the purpose of collecting open data. This proposal comprises the re-working of the gamification backend, along with ideas and implementations of the presentation of the badges, to make it an important part of the Open Food Facts experience.<br><br>

* 2 by 2, scanned by bar codes or input by text (supermarket mode)
An important usage of the Open Food Facts database is in the are of products comparison. Currently, some comparison tools exist (e.g. displaying products on a chart, comparison of nutrition facts with the average of a category), but they are not complete and they are only available on the web. This feature is about bringing these tools to (one of) the mobile application(s), allowing the users to:
* the web feature of comparing nutritional info of products of the same category
* compare pairs of products (one-to-one), scanned by bar codes or input by text (supermarket mode)
* charts on mobile
* bringing to mobile the feature of comparing nutritional info of products of the same category
* bringing charts to
* etc.<br><br>

EU packaging codes are those little logos on food that -once decyphered- will tell you where the product was packaged and produced. Unfortunately, the data comes in many formats (XLS, CSV, HTML, and yes, even PDF).

This project is building on the basic Python script we have for 3 countries, and extend it to the rest of Europe.

=== Add content management capabilities to all static pages of the product opener ===
The Product Opener server side software contains, besides the product pages, lots of pages with helper text, explanation and extra information about the elements of the Open Food Facts environment. Currently, these texts are in the source code, or, in the best cases, stored and edited on the wiki and regularily migrated to the Open Food Facts database site. This project is about implementing / integrating a content management system to allow this content to be easily authored by moderators of the site.

=== Tool for syncing with Wikidata on additives ===
The purpose of Open Food Facts and Open Beauty Facts is to provide the facts, not to issue judgement. Thus, we heavily rely on external sources of information (Wikidata) in what concerns the facts we present about the attributes of food products (such as additives, labels, ingredients, etc). This project is about providing a tool to better integrate these external data sources, including but not limited to:
* Automatically fetch relevant information from Wikidata about categories, labels, additives, ingredients…
* Display them in a human readable way on relevant pages and as tooltips
* Expose this information in the API.<br><br>
