Community-built databases have been established for diverse groups and communities. While traditional community-built databases are driven by a professional and technically-oriented audience, the rise of community-built databases shaped by the Net Generation has its own particular problems and issues. We begin this chapter with a definition of the concept of well-being for youth as well as the developmental processes that lead toward well-being. Next, we discuss the problems, issues, challenges and requirements for positive well-being that may arise in the context of community-built databases. We then propose conceptual and design principles to mitigate these problems, address the issues and provide mechanisms to enhance the developmental processes that lead to positive social, emotional, moral and cognitive outcomes. We further propose a framework and architecture that embody these principles in terms of four key dimensions, namely: web interaction, social collaboration, semantic integration and community governance. Finally, we conduct an exploratory implementation to illustrate key aspects of the architecture and framework to enhance youth well-being and support their needs.
