Agenda

1. General: Are there other agenda points?, 2 mins
2. ROS 2 with Cyclone + iceoryx, Matthias had an Eclipse talk, video
3. Data processing chain with modification of received data
4. Discovery use case

Minutes

1. No
2. There are different possibilities to implement this
   • Having the option to try to get the ownership on subscriber side with the possibility that this can fail and the user can decide hoe to deal with this
   • Enforce by configuration and discovery checks that a subscriber that needs to modify the received data is the only one and the publisher does not store the last chunk
3. Notifying subscribers when subscription state changes
   • It would be good to extend the events for Listeners and Waitset to allow to get notified if the subscription state of a subscriber changes
   • The refactoring of the service discovery has to ensure that it is possible to wait with Listener or Waitset on changes of the service registry
