OTB User Days 2021

Dear All,

We are planning the OTB User Days 2021 by the end of this year, and we need you! This meeting will be held in Toulouse and it will be a great opportunity to discuss around OTB, its new functionalities and upcoming features.

Let us know the dates you prefer by completing the poll below. This event is open to everyone, regardless if you’re a long time developer or a newbie :wink: We’ll choose the best slot according to your votes!

Of course, this event depends on the evolution of the sanitary conditions and we’ll probably have to make some adjustments to make it happen. We are also planning to broadcast the presentations online.

Thank you a lot for your answers!

I heard the Opensource Experience Meeting will be held on week 45 in Paris. We may want to avoid organizing our User Days during this meeting.

Dear all,

According to the results of Julie’s poll, the OTB User Days 2021 will be held from November 29th to December 1st in Toulouse, France.

On Monday and Tuesday morning, we will hold a conference focused on OTB and it’s usages. If you wish to propose a presentation, don’t hesitate to contact us.
On Monday and Tuesday afternoon, we will have a brainstorming about some subjects related to OTB. We will also talk about the roadmap of the project, and the organization of the priorities.
On Wednesday, we will hold a hackaton (developers oriented).

In order to organize the event, we need to know who is planning to come. Could you please register by answering this form ?


We are looking forward to see you there.

Some colleagues that can’t be there, have asked me if presentations will be recorded?
I think that it could be great.

We are planning on recording the presentations. But we probably won’t stream the brainstorming/discussions…
