W3C Workshop on Access Control Application Scenarios
Call for Participation 17 and 18 November 2009 -- Luxembourg


Participation is limited to people who submitted position papers (this includes co-authors). We need all participants to fill out the registration form which is required for logistical purposes. Registrations will be accepted up to the end of Monday, 9 November.

The program committee is currently reviewing the position papers and we plan to invite presentations on selected papers. Presentations should be short (15 minutes or so) and focus on salient points that are relevant to the workshop's goals. We aim to encourage plenty of discussion!

Workshop Goals and Scope

This workshop brings together worldwide research and user communities to explore evolving application scenarios for access control technologies, such as XACML. Results form a number of recent European research projects in the grid, cloud computing, and privacy areas show overlapping use cases for these technologies that extend beyond classical intra-enterprise applications. At this workshop, we will explore commonalities between different application scenarios, and standardization needs (at W3C and elsewhere) above and beyond the technology substrate that exists today.


We aim to enable a dialogue within a broad and diverse audience, spanning practitioners, implementers, and researchers.


The workshop is intended to discuss issues around access control in very wide sense, encompassing conditions and rules derived from the fact of accessing information. Topics that might serve as appropriate discussion points for position papers include, but are not limited to:

The workshop will examine experiences and recent research results in these areas, their need for agreed semantics, the need for extensions to existing access control languages, and perhaps for radically new approaches.

Workshop Goals

This workshop is intended to explore the wider space of access control applications. It is W3C's goal to facilitate a broad dialogue of relevant industry and research players. By identifying commonalities between access control applications across diverse use cases, the workshop will help identify standardization opportunities in the access control space, both at W3C and elsewhere.

Requirements for Participation

Position Papers

Position papers are the basis for the discussion at the workshop. These papers will also be made available to the public from the workshop site.


Position papers should contribute to the workshop's discussion about

They should also explain the participants' position with respect to possible specific work items that W3C could take up in within the workshop's broader scope.


All papers should be 1 to 5 pages, although they may link to longer versions or appendixes.

Accepted position papers will be published on the public Web pages of the workshop. Submitting a position paper comprises a default recognition of these terms for publication. Allowed formats are (valid) HTML/XHTML, PDF, or plain text. Papers in any other formats will be returned with a request for correct formatting. Good examples of position papers can be seen in the W3C Workshop on Languages for Privacy Policy Negotiation and Semantics-Driven Enforcement.

The Program Committee may ask the authors of particularly salient position papers to explicitly present their position at the workshop to foster discussion. Presenters will be asked to make the slides of the presentation available on the workshop homepage in HTML, PDF, or plain text.

Position papers must be submitted via email to team-policy09-ws@w3.org no later than 27 October 2009.
