Workshop at ISWC'06, Athens, GA, USA, Nov 2006

WORKSHOP MOTIVATION. Policies are pervasive in web
applications. They play crucial roles in enhancing security,
privacy and usability of distributed services, and indeed
may determine the success (or failure) of a web
service. However, users will not be able to benefit from
these protection mechanisms unless they understand and are
able to personalize policies applied in such contexts. For
web services this includes policies for access control,
privacy and business rules, among others. There has been
extensive research in the area, including the Semantic Web
community, but several aspects still exist that prevent
policy frameworks from widespread adoption and real world
application like for example:

  *  Adoption of a broad notion of policy, encompassing not
     only access control policies, but also privacy policies,
     business rules, quality of service, and others.
  *  Strong and lightweight evidence: Policies make decisions
     based on properties of the peers interacting with the
     system. These properties may be strongly certified by
     cryptographic techniques, or may be reliable to some
     intermediate degree with lightweight evidence gathering
     and validation.
  *  Policy-driven negotiations may be one of the main
     ingredients that can be used to make heterogeneous peers
     effectively interoperate.
  *  Lightweight knowledge representation and reasoning
     should also reduce the effort to specialize general
     frameworks to specific application domains
  *  Solutions like controlled natural language syntax for
     policy rules, to be translated by a parser into the
     internal logical format, will definitively ease the
     adoption of any policy language.
  *  Cooperative policy enforcement: A secure cooperative
     system should (almost) never say no. Whenever
     prerequisites for accessing a service are not met, web
     applications should explain what is missing and help the
     user in obtaining the required permissions.
  *  Advanced explanation mechanisms are necessary to help
     users in understanding policy decisions and obtaining
     the permission to access a desired service.

This workshop will bring together researchers interested in
the field in order to discuss and analyze important
requirements and open research issues in this context,
focusing on policies in general and their integration into
trust management frameworks, as well as on approaches to
increase system cooperation, usability and user-awareness of
policy issues.
