Title: XACML Conference Call Minutes

XACML Conference Call

Date:  Thursday, July 11, 2002

Time: 10:00 AM EDT

Tel: 512-225-3050 Access Code: 65998 

 

Summary

Review of action items, schema progress and discussion of next face to
face as well as scheduling. Schema has decided to define functions in tables
and may have an interchange format to create schema of functions. Datatypes will be defined as URIs.
The issue of scheduling was discussed. There is some concern over the process
SAML is facing with errata. The consensus is to still push for Sept 1
submission with implementations and open review period during August.

 

There will be an adhoc schema subcommittee
meeting Friday 7/12 from 10-12 Eastern in addition to next Monday's call.
Also expect an extra meeting again at the end of next week.

looking at it. Not expecting a response.

Hal - If cannot come up with difference
Rights Language and Access Control, membership in OASIS requires them to make a
statement regarding IP.

 

Schema Subcommittee Report (Anne)

Discussed issue of how functions and
predicates are declared. Decided having schema is useful, but doesn't
change way the basic XACML
PDP has to be built and structured. Going to define functions in tables and
important for PDP to know the types of arguments to the functions and return
values. Datatypes specified through a URI. Intend in
the future to define a schema for an XML interchange format and Daniel has
proposed a draft. May not be in scope of XACML 1.0. Then can define mapping from table to
function. Element name could be function name or generic function element. For 15 generic. When domain defines custom function, need to
be spelled out in table and URIs for datatypes need to be specified and created if don't
already exist. Condition in a rule requires to return
a Boolean. 

Subset of XPATH function still in discussion. Still
discussing small bits of schema that need resolution, but not major conceptual
issues.

Tim - Do we want to have an adhoc schema
meeting Friday afternoon or wait until Monday? Plan for Friday at 10-12
Eastern.

Tim will sent out
short list of topics late today. People should review schema before tomorrow.

 

Face to Face

Goal - Complete specification

Possible to finish by August
1st.

Ken - open review process?

Carlisle - Could open for comments for 2-3
weeks in August. Have concern with what is happening in SAML right now. Now in OASIS public review. During this time, people in SAML
continue reviewing spec and during implementation, have found various errata.
Question about whether those changes can be incorporated into spec and probably
can't and will have to be incorporated into 1.1 spec.

Two possibilities - work through OASIS
or on Sept 1 don't submit, but use extra 3 months to examine spec and fix
up any errata.

Bill - prefer not to postpone, maybe
propose a beta spec?

Ken - during implementation may come up
with issues. Will we be able to perform any interop
testing?

Ken - I would like to see some external
comments before submission.

Anne - in reviews at sun have asked for
guidance for implementation and explanation of specification.

SAML issues are issues that are less than
optimal, not broken. Relate to extending SAML or some times of XML processing. 

 

Conformance

Anne - volunteered at f2f to come up
with Conformance test cases. Waiting to complete J2SE
examples first. Is next priority. Will consist of input context, policy context and output context.

 

Issues list - please look through and
review and let Ken know so he can update the issues list.

 

Motion to adjourn
