Subject: [xacml] xacml schema sub-committee (from Ernesto)
Hi, i am sending this msg from Ernesto (he seems to have problems posting to the list) best -p ---------- Forwarded message ---------- Date: Thu, 4 Apr 2002 15:43:07 +0200 From: ernesto damiani <edamiani@crema.unimi.it> To: Pierangela Samarati <samarati@dsi.unimi.it> Subject: pierangela me lo posti tu? grazie! Colleagues, I enclose a first proposal for the division of work among different task forces within the new Schema subcommittee. The rationale for the two main task forces would be focusing: 1. on the definition of XML types representing a policy and policy combinator, leaving rules as black box elements 2 on the definition of XML types representing rules and their internal structure Two minor task forces should deal with identifiers and obligations; I aslo included a task force on extensibility points. Of course this proposal is only a raw first attempt, made to be amended and modified by your input via e-mail. I especially encourage Tim feedback on my subdividing the current schema types among thematic task forces, I surely made many mistakes. Proposals for modifying this task force list (or having a completely different one) should be discussed on the list in the next few days. Once we have a task force list in place (hopefully to be approved by next Monday), people can start joining the task forces and working off line at fine tuning the parts of the schema under their bailiwick. From that point on, our Moday concall will be mostly dedicated to reviewing and approving decisions and modifications that the different task forces will proposed. What do you think? Rgds Ernesto ------------------------------------------------------------------------------------------------------------------- XML SCHEMA SUBCOMMITTEE TASK FORCES ON POLICY SYNTAX 1. TASK FORCE ON POLICY-LEVEL TYPE SYSTEM This task force will focus on XML types representing policy combinators, individual policies and their components, as well as on elements belonging to those types. Internal structure of policy components will not be defined by this task force. Current schema reference types: Complex type PolicySetStatementType Complex type PolicyStatementType Complex type PolicySetType Complex type PolicySetDesignatorType 5Complex type PolicyDesignatorType Complex type RuleSetType Complex type RuleDesignatorType Complex type RuleType 2. TASK FORCE ON RULE-LEVEL TYPE SYSTEM This task force will focus on XML types representing rules and their components, as well as on elements belonging to those types. Integration of components to form policies will not be defined by this task force.

TASK FORCE ON OBLIGATIONS This task force will focus on XML types representing obligations, as well as on elements belonging to those types. Current schema reference types: Complex type ObligationsType Complex type ObligationType 4. Task force on XACML IDENTIFIERS e.g., Requestor, Time of day, Attributes 5. Task FORCE ON XACML EXTENSION POINTS
