KYOTO -- "Open source," a now familiar term on the Internet, originates from a method of developing computer software that has enabled the creation and continuous improvement of the successful Linux system.

The idea, which is to let anyone participate in the development of software by opening its source code and allowing free redistribution, is now beginning to spread beyond the boundaries of the Internet and gain a wider scope.

Earlier this month, more than 150 people from across the country gathered here for a unique forum under the theme of "Open Source," bringing together their various backgrounds and interests in the search for new business and social models to fit the postinformation technology revolution era.
