Since 2015 Taiwan launched a three-year project, asking users in government to use ODF as the standard file format. Why did we choose ODF instead of OOXML, which has a lot more users in the world? What's the differences? What's the advantages using a stable and open spec file format?

In this talk we'll discuss from the following subtopics: 1. Introduction to standard formats for office documents 2. Economic advantages of de-iure standards over de-facto standards 3. Comparison of standards: ODF (OASIS) vs OOXML (ECMA) 1. Differences in the standardization process: regular vs fast-track 2. Differences in the relationship with other established standards 3. Differences in the standardization outcome: the underlying XML 4. True interoperability vs false interoperability 4. How to use ODF to improve interoperability with non standard formats 5. Fonts as a key element of interoperability (for English documents)

People would focus on comparing LibreOffice v.s. Microsoft Office. But no, it's not a war of software. It's actually a war of file format.
