We're running a super quick survey (1mn) to get some ideas from the community, regarding gamification in Open Prices.

Badges

What kind of badges would you like to see?
Do you have examples of apps or (community contribution) websites that do things neatly?

cc @Freso you mentioned a digital common doing this the other day?

Discourse has a badge system: https://forum.openfoodfacts.org/badges

• grouped by "Getting started", "Community", "Posting", "Trust level"
• seems to be public (in terms of listing + users awarded)

[Freso]

That was for "year in review", and I linked it in the meeting notes :)

For badges, BookBrainz does badges: https://bookbrainz.org/ (e.g., my badges)

nice !

I wonder if they have also a page that lists all the available badges + number of users who achieved them

also : https://www.youtube.com/watch?v=XEZROTq1lY0 (they built in 2016 with GSoC)

Some ideas, extracted from a private Slack chat:

• Buddy : Added X prices from someone else's proofs
• Quality patrol : Flag a wrong price or proof
• Swiss Army person : Contribute using X different tools (web, mobile, api, rgpd)
• Certified reuser : Have a project listed in the known reuses
• Early bird : Be the first to add a proof on a challenge
• Beta-tester : Use a feature while it's still an experiment
• Product creator : Add X missing products using Open Prices
• Hard worker : Add X prices in a single day (minimum 100 or 200)
• Contributing month-ster : Be the most active contributor in a given month
• On a roll : Contribute for X consecutive months
• Impact seeker : X Prices added to most scanned products
• Completist : Add X prices in each Open Food Facts flavors
• Camper : Add X prices in a single location
• Regular : Take pictures X different days in the same location
• Sponsor : Donate to support Open Food Facts (not sure how to track this one, and if we want to, since it's a bit pay to win)
• Hacker : Contribute on GitHub (hard to track automatically, Translator would be the same with crowdin)

Early bird : Be the first to add a proof on a challenge

Maybe “be among the first” and count the first 24 hours of a challenge? Or the first 1% of one (in case we want to do "spot"/"lightning"/short-lived challenges (like for a day or a few days)) maybe.
