Description of Working Group: 

The goal of this working group is to define, specify, and develop the Application Configuration Access Protocol as a general access mechanism for per-user and per-server structured lists of information. In addition, the Working Group will specify how to use the protocol to store specific structured lists, initially application configuration options and address books. 

The Application Configuration Access Protocol is a proposed solution to the problems of client configuration for users of the internet. 

Given the increasing prevalence of network access points and rapidly increasing numbers of users with diverse needs and settings, there is a phenomenon of internet application users who typically connect from more than one physical location and/or operating system to use the same set of internet services and applications. These users must recreate sets of personal configuration information for each system, session, and location that they use. This may include information such as application options and preferences; personal or shared user data such as address books, bookmarks, or subscription lists; or shared data for internal client use, such as authorization group lists. 

The products of this working group will be:

·   A formal specification for the protocol 
·   Formal specifications of datasets used by the protocol and related extensions to the protocol
·   An RFC intended to move to a Standard in a timely manner 
·   A specification for extensibility of the protocol in the form of a framework document
·   Additional informational and/or experimental RFCs as necessary to amplify and/or extend ACAP

Note on goals and milestones: because the work of the ACAP WG is based on the previous work done on IMSP, there is justification for a somewhat more aggressive schedule than is customary.
