This is the correct link for the online conference. However, if you see this page it must be because OW2con’21 is not open yet.
As you know, OW2con’21 will be held as an online event:
With OW2online’20 we created the first major virtual open source event in Europe. With over 300 participants, 35 presentations and speakers representing 13 nationalities, it was again, a true expression of the European open source ecosystem.
All conference material (videos and slides) from OW2con’20 are published here: https://www.ow2con.org/view/2020/Videos
The OW2 team remains available to answer your questions or comments, do not hesitate to contact us, please write to email@example.com.
We look forward to hearing from you soon.
The OW2con’21 Event Team.
