    <pub:abstract><![CDATA[In this paper, we describe a policy-based access control
implementation for Task Computing using the Rei policy engine.  Task
Computing lets ordinary end-users accomplish complex tasks on the fly
from an open, dynamic, and distributed "universe of network-accessible
resources" in ubiquitous computing environments as well as those on
the Internet.  The Rei policy specification language is an expressive
and extensible language based on Semantic Web technologies. The Rei
policy engine reasons over Rei policies in OWL and domain knowledge to
answer queries about the current permissions and obligations of an
entity.  To provide unobtrusive and flexible access control for Task
Computing, a framework was created in which several Rei policy engines
were endowed with Web Services APIs to dynamically process facts from
clients, the private policies of service providers, shared policies,
and common shared ontologies. The framework is implemented and
deployed for Fujitsu Laboratories of America (FLA), College Park
office and evaluated.  Categories and Subject Descriptors
