Open Source and Open Content refer to software, media, and books that are free to view and modify. Sometimes that may be free of cost or sometimes a fee will apply. We believe that Open Source software is of great value and allows intellectual progress to continue at a faster rate and least cost to society.
Open Source software exists throughout the world. Many of these products are well know, and many are relatively unknown to most. A few examples are Linux, Apache webserver, Mozilla Firefox, Mozilla Thunderbird, Open Office, VLC, Gimp, and Handbrake. There are many others as well. It allows people to interact with the different forms of media on the internet and off of it as well.
Open Content is the idea that knowledge is that such content is free or nearly free to reuse, revise, remix, and share with others both in public and private settings. Its the idea behind many of the open content books and websites like Wikipedia and Wikibooks which aim to provice the world with free educational content for a a vast array of subjects.
Open File Formats refer to computer file formats that are maintained by a legitimate standards organization. These formats are open to the public so that vendors and private communities can access it and write software that can read and write that format. File formats are the life blood of telecommunications and data. If you can’t read or write it without a license, it can become a huge problem to maintain and use.
