Ready, steady, ...

We are whirling - the preparations for the #opensearch events 2021 are already in full swing. That's why today it's Save the Date(s)!

In October, the international Open Search Symposium will bring together researchers and interested parties in #opensearch for the third time. The program will again include ideas, research results, practical experiences and discussions about Open Search. We are optimistic and plan the #ossym2021 from October 11 to 13 as a "real" conference on site at CERN* in Geneva and in parallel virtually on the web.

Warm-up: Because October is still such a long time away, the #ossym Spring Workshop will take place again on May 10, 2021 - online as a web meeting.

We summarize the most important information about the #ossym2021 events for you in this newsletter. More details will follow in the coming weeks and months.

Whether you want to join the discussion, actively contribute or just listen in ... Be part of it!
We look forward to seeing you!
