I hope it gave you a bit of context, and we also heard from Mikael about the guidelines. So the guidelines are very important, they're a big milestone, especially the data guidelines. The purpose of today in these two sessions is to invite a range of stakeholders representing a range of initiatives. So we have publishers represented infrastructures, data site, EU data and data repositories, all to provide their view about how they interoperate on the European scale and how they might interoperate with OpenAir. After that, there will be detailed instructions about the breakout groups. We will meet again after lunch and put you into groups, and we very much welcome your input into the data guidelines at that stage. Please, if you don't have a copy of the data guidelines, they have been printed out. Do email me on the below email address or get in contact with me and I can share them with you. They're not yet public, they're still within the consortium undergoing review, but today is the chance to talk further. So welcome, and I hand you over to Irina to chair the session. Thank you. A very good morning to all of you. I hope you all enjoyed yesterday's dinner as much as I did. I hope you all had a very good night rest and ready for another interesting day. We have four excellent speakers on this panel, which is Interoperability Panel, and we'll talk about interoperability between repositories and Chris systems, between data repositories, public data repositories and research systems, and also between publishing portals and repositories and institutional datasets. It's my pleasure to invite our first speaker of the day, Ed Siemens, from Eurochrys, and his colleague Danitsa Zendlukova will join him in the course of the speech. So Flo is yours, Ed.
