Our research group here at UMBC is interested in exploring how the
semantic web can be useful in supporting three areas: pervasive
computing, distributed trust, and agent communication.  What follows
are not proper use cases, but I wanted to submit something before our
call today.

PERVASIVE COMPUTING.  We are interested in suing semantic web languages
to support service description, discovery, matching and negotiation
for devices in a mobile computing or pervasive computing environment.
We are particularly interested in allowing devices to be aware of the
"context" they are in so that they can better perform their tasks.
We've done some preliminary work that has included developing a version
of JINI which uses DAML+OIL to describe services offered and sought.
We've also developed a system that uses RDF for service description
and matching in the Bluetooth Service Discovery Protocol.

DISTRIBUTED TRUST.  We are developing a system which uses distributed
trust to make authorization decisions, such as which users or devices
should be allowed to access or use what resources.  We are applying
this in several contexts: web services, supply chain management and
mobile computing. We have begun using an ontology in DAML+OIL to
represent and publish the concepts that our distributed trust system
reasons about -- roles, constraints, permission, obligations,
prohibitions, policy, authentication, etc.

AGENT COMMUNICATION.  We are using DAML+OIL to support agent
communication in a multi agent system.  Our ITAALKS application can
send announcements of new talks and events thought to be of interest to
a registered user to that uses personal agent.  It in turn consults
the user's schedule, location and other agents to decide whether or
not to add it ot the user's calendar.  uses DAML+OIL as the content
language.  The agent communication among these agents is done with the
FIPA ACL and uses DAML+OIL as the content language.
