As part of the SocialPhysics initiative we are developing both a software framework, and on top of it, an initial base application. The framework embodies a set of principles that govern natural, real-world relationships. It is based on the idea that a person should have full control over information about themselves and their relationships with others. People participate in multiple groups and systems, each with its own social protocol. Since what people are willing to share and say about themselves depends enormously on the context, there is a need for persons to be able to manage multiple versions of their identity. The framework makes it easy to create and join many different kinds of networks (e.g. groups, teams, and communities), each with its own rules for what is shared, what is private, and what is measured.
