Introduction to Participatory Infrastructures (PI). Multi-Agency Systems. Participatory Semantics for multi-agency systems, including participations and attributions. Object Component Systems for PI (Java, DCOM, CORBA, ODMG). Objects and interfaces. Semantics of: connectable objects, persistent objects, monikers, automation. Introduction to reflection: accounting and interface participations. Reifying changes in behavior. Application to multi-agency systems. Future of Participatory Infrastructures.

Through team projects, students will gain experience using the methods, principles, and technologies of PI. Team projects will illustrate techniques for building and reifying distributed multi-agency systems.

Suitable for computer science graduate students and advanced undergraduates.
