isapiens@home server
- Exposes
VOs functionality to agents
- Manages
VOs (registration and cancellation)
- Allows to registers and subscribe
rules on VOs’ resources Virtual Objects Container
- Is the container for the agents
- Manages agents’ life-cycle
- Manages timed/untimed messages
- Offers a «Yellow Pages» services
through the “directory” agent Agent Server

The «Yellow Pages» agent
- advertisement (registration)
- searching
- facilities for sending messages to registered agents
Offers the following services: Services are based on: Roles and Properties (key,value) Services are offered by the “directory” agent The class of the «yellow pages» agent is AgentDirectory
