The Interoperability of Documents (was: A War of File Format)

My official talk in OpenSUSE Asia 2017 (LibreOffice mini Conference Japan 2017), talking about the interoperability of documents.

1. The Interoperability of Documents (Was: The war of fle format) LibreOfce mini Conference, Japan, 2017 Franklin Weng LibreOfce Migration Professional / Certifee Trainer Member, Certifcation Committee, The Document Founeation Presieent, BoD of Software Liberty Association Taiwan
2. In This Session Originally I'd like to focus on comparing ODF and OOXML But I found an even more important point So I'm going to talk about documents' Interoperability
3. Document Generation And Interoperation in Ancient China Source：https://goo.gl/wpL2QY Source：https://goo.gl/bMnvPH （良い馬） (The Emperor said: "I got it.")
4. Document Generation in 20th Century
5. Document Generation in 20th Century
6. Document "Interoperation" In Old Days
7. Therefore, In The Old Days What we learn was to generate "beautiful" documents.
8. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages)
9. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages)

12. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages)
13. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages) Some mean bosses would ask for "aligning with no error"
14. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages) Some mean bosses would ask for "aligning with no error" So we use "Invisible table" to align
15. Therefore, In Old Days We try to just "put" words to the position. (So we use Space to move words, and Enter to change pages) Some mean bosses would ask for "aligning with no error" So we use "Invisible table" to align We used special fonts and
16. All Of The Above Had no any problem in old days because we mainly used "paper- based documents". However, in the new era we start to use digital documents, and problems arise….....
17. Document Interoperability Now
18. When Receiving Digital Documents Receivers may not be able to open (because no software or different version) Receivers may not be able to see the contents (because no such fonts) Receivers may not understand the contents (because the document's typesetting is in a mess)
19. In 21st Century Document Interoperability ≠ Document Exchanging
20. In 21st Century Document Interoperability = Working together better
21. So, We Need To Understand How to generate an "interoperable" document
22. Interoperable Documents Open spec, stable file format standard Correct concept of generating documents Use open fonts
23. 1. File Format
24. De-jure and De-facto Standards OOXML Office Open XML ODF OpenDocument Format
25. Using OOXML as Standard... Office 2007 Office 2003 2003 04 05 06 07 08 09 10 11 12 13 14 15 16 17 Office 2010 Office 2013 Office 2016 Office 2000 Office XP Office 97 Office 95 Office 4.3 Office 4.0 Office 3.0 Have you ever tried to generate a docx file with Office 2013 and open it with Office 2007? Can it be opened successfully?
26. Open Document Format Selected as national standards of file format in UK, France, Sweden, …… and Taiwan Open spec ISO Standard Simple, Stable

42. Microsoft Japanese/Chinese Fonts • MS 明朝 (Japanese) • MS Gothic (Japanese) • 微軟正黑體 (Chinese) Do you know their license?
43. Open Font: Noto Sans / Serif
44. Open Chinese/English Fonts • Japanese Fonts – Noto Sans CJK JP（SIL Open Font License）、Noto Serif CJK JP（SIL Open Font） https://www.google.com/get/noto/ – Kochi Mingcho (東風明朝) https://en.wikipedia.org/wiki/Kochi_font • English fonts – Liberation Fonts (SIL Open Font License)
