- Management: (project, software architecture, system management)
- Online: (online filter system, data archiving)
- Offline: (Implementation of data model, databases, event visualization, monitors, & data archive management, processing, data distribution, Librarians: calibration, simulation, track reconstruction, shower reconstruction, energy reconstruction)
- Working groups will provide calibration procedures, simulation routines, reconstruction algorithms, filter algorithms, and analysis code in general.
- Data Handling Librarians need to be active members of the physics analysis groups.
