Open Food Facts days 2022.png


In order to encourage discussions between participants in the Open Food Facts project, we are once again organising two days of getting together, the "Open Food Facts Days", on Saturday 1 - Sunday 2 October in Paris (at the Académie du Climat, 2, Place Baudoyer in Paris 4e (between the Saint-Paul and Hôtel de Ville metro stations)) and by videoconference (link to come).

Saturday will be dedicated to presentations and workshops proposed, presented and led by the participants of the project (contributors, developers, re-users etc.).

The General Assembly of the association will take place on the morning of Sunday 2 October from 10am to 12pm. And the afternoon programme will be free in order to be able to continue the exchanges and reflections on the points identified during the presentations, workshops and the General Assembly.


We hope you can join us on 1-2 October. Please register for the Open Food Facts Days (free registration) so that we can best organise this event and send you all logistical information.


Open Food Facts is firstly a community of people. Thanks to our sponsors, we can provide grants to let people from all over the world attend to the Open Food Facts days.

These grants can fund travels and accommodation. Our funds are limited.

Deadline for application: A committee (composed of the board and the permanent team) will select the candidates by the 25 of August.

If you are interested in requesting a mini-grant, please fill out the following form.


Saturday's agenda is wide open: could you present what you do on Open Food Facts? Would you like to lead a workshop on a particular topic? And conversely, are there any topics you would like others to present? You can send your proposals to, or add them at the end of this page, or share them on Slack (Slack is a discussion space between contributors, sign up to join) in the #journeesoff channel.

Information for the participants


We are really looking forward to meeting you in person at the upcoming Open Food Facts Days on the 1st-2nd of October 2022 from 9:15 am at the Académie du Climat (2, Place Baudoyer, 75004 Paris).

In this email, you will find some information worth noting concerning this event and we would greatly appreciate your responses as it helps us to better organise:

1 - Language

Open Food Facts Days will be mainly in English. Some short sequences will be in French (with whispered translation). For those who only speak French, there will always be at least one track in French.

2 - Open programme

If you haven’t already, please get in touch to submit your proposal for a workshop or a lightning talk (approx. 7 min presentation on a topic) on this dedicated event wiki page (see section just above).

3 - Bring chocolate (if you wish)!

Yes, you read that right. If you can, please bring a chocolate bar from your country to display in a fun way the different nationalities that will be present (and to have a nice treat!)

4 - Meals

Friday ​Night

Join us for a drink or/and dinner right next to the Vincennes Castle at Le Sauvage bistro, 30 Av. de Paris, 94300 Vincennes, from 19:00 o’clock. Please confirm to [[1]] if you will be coming, so she can book accordingly.

Saturday Lunch

The idea is to have a “bring & share” lunch at the venue. So please bring something to share. Plates, cutlery, cups and water fountains will be provided. Please note that the Académie de Climat has a policy of not using disposable plastic (or avoiding it to our best ability). Therefore, we also recommend you bring a reusable water bottle if you have one.

The closest supermarket is 1 min walk away from the Académie.

Saturday Evening

After the first day, we will go socialise over a drink at the Académie du Climat’s bar “buvette”. Following that we will go dine at a nearby French restaurant Le Trumilou. If you are interested to join, please write to [[2]] so we can book accordingly.

Sunday Lunch

Each one buys something like a sandwich from nearby (some addresses below) or brings something for themselves.

*Please note that there will not be cutlery this day.

Closest bakery

Bagels next to that bakery.

Nice nearby coffeeshop: Le Peloton Café

Bakery Ernest & Valentin (near metro station Hôtel de Ville)

Another bakery (closes at 12.30 on Sundays).

Patisserie Aux Merveilleux de Fred.

5 - Covid information

- The “vaccination pass” has been lifted in France in all areas.

- The COVID certificate is no longer required as of 1 August 2022.

- Travellers no longer have any formalities to complete before arriving into mainland France, and the COVID certificate can no longer be required.

If you happen to be Covid-positive after the event, we ask you to please notify the team, so that we can inform the participants as they would be a potential contact case.
