It is a bit late and rush to know and organise a small-size local meetup of Document Freedom Day in Hong Kong, to let people to share their experience on use and sharing of computer documents. I just got launch of DFD from Software Freedom Day mailing list.

March 25, 2009 - first Document Freedom Day

DFD 2009 aims to raise awareness on the importance of accessible document formats and open standards in everyone's day to day activities, as metioned on SFD mailing list.

Open standards are agreed document definitions which are available to the public to review and use. They cannot depend on formats or protocols that are not open standards themselves. Open standards protect governments, businesses and the wider community of computer users from vendor and data lock-ins. Such lock-ins obstruct users from exercising their full freedom in software and the information they access.

We can imagine that some of old proprietary documents are not accessable again after old document programs are retired or upgraded to new version.
