<H3 CLASS=ABSTRACT>Abstract:</H3>
<P CLASS=ABSTRACT>One of our goals when building the University of Michigan Digital
Library (UMDL) was to provide an architecture for a digital library
that can continually reconfigure itself as users, contents, and
services come and go. This has been achieved by the development of a
multi-agent infrastructure with agents that buy and sell services
from each other using our commerce and communication protocols. We
refer to the services/protocols offered by this infrastructure as
the Service Market Society (SMS). The SMS allows for the
decentralized (scalable) ongoing configuration of an extensible set
of users and services. We describe the protocols, services and
agents that embody the UMDL SMS and show how they achieve our stated
goals.
