 Thank you, everyone. Good afternoon. In this short talk, I will talk about currently recent years in Taiwan, we are adopting open-document format in the government, the central government asks everyone to use ODF. And I will give you a short background, introduce and then talk about what do we need in current ground. So, on the first, let me show some background. Actually, in 2009, we have already made it as our national standard. That means since 2009, our government, the official document should use ODF, but without any surprise, nobody cares. Okay? Everyone is still using Microsoft Office. Nobody cares about this. But then in 2014, an incident changed the condition. Do you know what it is? No. The UK government. UK government declared that the whole government used the open-document format and office suite, the right foundation office named the GOV office. And so, in the bottom half of 2014, our national developer council that's in our central government, level one organization in our central government started a series of discussion. So, that is an up-to-down power. That is an up-to-down power to awaken, accordingly awaken, because we have already ascended there, but we never use that. So, now, we have the chance. And in early 2015, in one of our county, here as a Taiwan, and even on this here, they started to migrate. At first, they called the office, but then I suggested them to use the liberal office. And they want to migrate the whole liberal, to the whole country, the whole county government, including the schools, everyone. So, I got the chance to help them. And until now, 2017, they are still using LibreOffice and ODF. They never give up. So, I think that is a very big victory for us. And I present that in the LibreOffice conference 2015. That's my presentation that time. And out of my expectation, after my presentation in 2015, amazing chain reaction happened. Some bloggers, they wrote articles to report about my presentation. Yes. And I, someone wrote me a mail telling me this, and I collected all the articles. And then, I happily, happily report this to the director saying, hey, good news, sir. Now, the whole North Taiwan is migrating to ODF. I believe that, well, I believe that the office must have cost me a lot that time. I believe that. But it's been already a fact. So, he asked most of the local government to submit the proposals to migrate ODF. Okay. That's the background. And during these years, actually, we are not only telling people to use LibreOffice. As hard we told them is the format is very important. We need to compare format to format. Compare ODF and OXMO, which is used by Microsoft Office. If we compare the format, the advantage of ODF is very, very clear. But if we compare OpenOffice or LibreOffice or even Caligula between Microsoft Office, then everyone will say, hey, you like this, you like that. It is not a good thing. So, we focus on format. And by telling them now, we have many tools to use. We have many tools to use. And we need more tools for people to use. For example, of course, LibreOffice, Apache Office, also Google document can save us ODF. And GloF is sweet, just like every word between your name and Caligula. And sometimes we have Web ODF library to make some web use. And I will tell them not, don't use Microsoft Office. Why not? Because the ODF file is saved. If you open it in the LibreOffice or other Office suite, it will be in the home-ass. The CTO in Taiwan, CTO in Microsoft, CTO in Taiwan, admit that they added something in the ODF file. So, I told people not to use Microsoft Office, not because we are against Microsoft, because Microsoft do not process the ODF file correctly. And also, we attend the ODF file to test more. So, now we enter the Caligula. Of course, currently, LibreOffice is the main tool we tell people to use. You know, our training course is on the LibreOffice tool. But I would like to tell people that it's not your only choice. Okay? Caligula, actually, I translated the Caligula very many years ago. And I know the changes from Caligula and also Pre-Tah became independent. So, in this time, I tried Caligula again. Okay? This design is really simple, very simple, very different. But I won't say it's hard to use. No, it's actually very simple. And another one is that currently, as far as I test, it can only save as ODF. If you try to save it as DOCX and the DOC, and it will tell you, oh, it's not good, then tell you, oh, we have no filter to save that. So, actually, there is no way to save as DOC or DOCX. And I think, actually, it is very good. Okay? Or users would still like to use DOCX. But of course, there are some things we need in Caligula. That's not, okay. That's not here yet. The most important is the CJK support, Chinese, Japanese, Korean. And this CJK support is just like, for example, this is liberal office. And in the character, we can see there are action, action, and the Western text phones we can select. But in the Caligula, we have only one. In the Caligula, we have only one. We can only choose one phone for both Western and Asian. But actually, Asian and Asian are very different. We need different ways to process it. Okay? Also, text direction. Currently, now, only Taiwan and Japan have vertical writing. That is supported by liberal office but not in Caligula. Okay? For other features, actually, the ODF saved by Caligula is not quite interoperable. For example, if I open this, S4 is generated by liberal office and I open it in Caligula, in stage, it's okay. But I wind up slides in Caligula and I open it with liberal office and it becomes like this. The phone size is different. It will change something. So, it's the need to make it more interoperable. And that can be done in the ODF process. And I hope more people can join. And the other features of translation, yes, it's been a long time. I've not touched the translation again. So that's our responsibility. So finally, I know that Caligula is actually part of the KDE project. So it's not about compiling. I totally agree with that. But still, I would like to make it another choice for people to use, to create documents. And I hope in KDE community, we will have more. I've concerned it. Okay, thank you.
