Berners-Lee, the Web's inventor and founder of the World Wide Web Foundation, will make the announcement.
The formation of the group was announced last year. It is opening its doors with two programs respectively focused on leveraging Web technology to improve farming in Africa and teaching low-income young people how to create online content.
The first project seeks to enlist local developers to build a Web-based platform for farmers in desert areas in Burkina Faso, Mali and other places. The idea is to help these farmers communicate better, share information, and learn and improve agricultural techniques.
The second project, in conjunction with the Brazil-based Center for Digital Inclusion, will develop training for young people in how to create Web content that can be accessed via mobile phones and include voice and graphics.
