The entertainment system was belting out the Beatles' "We Can Work It Out" when the phone rang. When Pete answered,
his phone turned the sound down by sending a message to all the other local devices that had a volume control. His sister,
Lucy, was on the line from the doctor's office: "Mom needs to see a specialist and then has to have a series of physical therapy
sessions. Biweekly or something. I'm going to have my agent set up the appointments." Pete immediately agreed to share the chauffeuring. At the
doctor's office, Lucy instructed her Semantic Web agent through her handheld Web browser. The agent promptly
retrieved information about Mom's prescribed treatment from the doctor's agent, looked up several lists of providers,
and checked for the ones in-plan for Mom's insurance within a 20-mile radius of her home and with a rating of
excellent or very good on trusted rating services. It then began trying to find a match between available appointment
times (supplied by the agents of individual providers through their Web sites) and Pete's and Lucy's busy schedules.
