Given the vast experience in radioastronomy in the area and the potential availability of several expert radioastronomers in the area, we had the idea of organizing a “Radioastronomy in the VO” session to examine together the availability to radio data in the VO and try to identify the simplest steps to connect both worlds or at least to move slightly in the right direction. We would be talking about a 1.5 to 2 hour plenary session during the IVOA interop meeting in Groningen with a few small presentations to set the context and a discussion on what to do next. We would first like to invite you all to this session (either in person or remotely, giving a talk or just participating in the discussion) and would like to ask how do you think this discussion could be more useful to both parties. We will take care of all the logistics of the session.</div><div><br></div><div>An earlier similar discussion already took place in the context of the ESCAPE project and the notes can be found <a href="https://www.asterics2020.eu/dokuwiki/doku.php?id=open:wp4:wp4techforum5:radiointhevo" target="_blank">here</a>. Therefore, we could start the session with a summary of the conclusions from the earlier meeting by e.g. Francois Bonnarel from CDS and then try to identify the next steps to make all the Radio data easily available to the VO world and viceversa.
