 Okay. We talked about immigration from tiny OPS to Libro OPS. I'm the developer of the team and that's my chef. And that's the junior from the travel guide from Michel Miller-Valac, who wants, who use the tiny OPS and in future he will use the Libro OPS. We change tiny OPS because we have an old system used word 2003 with custom XML notes and that not works yet. So we use now Libro OPS and use Summit Libro Office and change the book, use RDF notes, as you take tour with bookmarks for show our some things we need for our books, e-books and web app. Presentation for too much people, sorry. And here is the first solution of our task pain. It's for our task pain which you need for some fixes. When we got the command from the Valac we must do bookmarks to refer some things to create later the books. And we need Libro OPS to fix some things or add some details to the some things. And that's the first production from the old system to Libro Office. This is another view from that and that also. And I develop on Tsai Sharm. I use it for our extension. And the basic form our extension is unit which has last to give us to and I created our views and windows and other things. And for the migration we use doc documents with comments. And the comments we created to bookmarks in code as a rear code with a button. And so the old documents were not failed or the information from our old documents were rescued to the new system. Yes, let me say something around why we did that. In the past we used Microsoft Office Word 2003 and that is now 20 years old. And the problem is you cannot use it. You cannot say don't touch a running system. That don't work in the future. We tried something. We packaged Microsoft Word in some VMs for Mac for Windows. We packaged MSIX system from Microsoft. And we packaged with VMware Synapse. And we tried anything to have the word running and running again. But it's not so easy to have live that. And our workflow was working now with this old word. We have to change that to the office to the liberal office because that's the only one. Maybe what we can have in the in the own hand in the future for us. And now we migrate this old custom XML architecture to the RDF system. And we migrated with the special node. And I will say some thanks to Armin Legrand. Because we did discuss together some ideas how we can let going run this migration from this old documents to the liberal office system. Okay. In some ways try more straightforward getting out playing the XML file which will be in the same time the whole year. Did you consider this? No. I don't hear. I hear it first now. But I'm not only the developer. The problem is we need to have the layout the layout the same. And the problem is only to use XML standard. It's not so easy to migrate to the same layout. We have to let the layout and use it further in the next liberal office. And that's the problem. You have some these custom XML text technology. You have some attributes in the database and we are in the right with the special task pane. We are connected with databases. We are resaving some information and we putting that back to the document. And after this working with these special documents we get an C sharp publisher to read all these documents and produce stuff for the app databases, A books on whatever we want, digital products. That's the problem.
