In order to realize the full potential of the World Wide Web as an open, dynamic, and distributed ``universe of network-accessible information'', it is important for web entities to behave appropriately. Policy management provides the openness, flexibility, and autonomy required to regulate this environment as entities can reason over their own policies and the policies of other entities to decide how to behave. Using policies also allows entities to specify expected behavior of entities they interact with. Entities can also adapt to increasingly complex requirements without the need for substantial changes to the structure or implementation through the use of policies.

Policy management includes policy specification, deployment, reasoning over policies, updating and maintaining policies, and enforcement. We propose that policy management is required for the web for (i) constraining different kinds of behavior including security, privacy, conversation, and collaboration, (ii) configuration management, (iii) describing business processes, and (iv) establishing trust and reputation.

The PM4W workshop will be held as part of WWW2005 in Chiba, Japan at Nippon Convention Center (or better known as Makuhari Messe). Makuhari Messe is conveniently located halfway between central Tokyo and the New Tokyo International Airport (Narita Airport). From the airport, it can be reached by bus or car in 30 minutes. Tokyo station is also only 30 minutes away by train (the JR Keiyo Line).

Submitted papers

We seek two kinds of papers: research papers that report on the results of original research and short papers that articulate a position, describe an application or demonstrate a working language or system. Both research papers and short papers will be included in the workshop proceedings. See the call for papers for more details.


PM4W will be a one day workshop consisting of invited talk(s), presentations of submitted papers, and (probably) a panel as well as time for discussion. See the program program page for details.
