Shared purpose and social contracts provide the economic and social framework for cooperation in the production of value that greatly exceeds the sum of individual efforts. Building on the success of Linux, Apache, and the Public Library of Science in the production of intangible goods, and the traditions of Ashoka and ThinkCycle.org, I seek to provide practical models for successful community ventures that address economic incentives, social contracts, and intellectual-property. These models will be tested and demonstrated through pilot ventures focused on creating sustainable solutions for currently underserved communities including a "documentation kiosk" to support the exchange of social services information, and "open informatics" methods to gather clinical data while preserving control over personal information.
