XACML 3.0 core wd 20 uploaded
The TC is encouraged to review.
F2F
Hal will create a poll to gather the final attendance count for the
F2F.
III. Issues Discussed
PDP REST Interface (PAP)
Hal noted that the current thinking on the list attribute
information would be in JSON and transported using a POST over HTTP
with the response. He offered that he personally would like to see
this done in such a way that doesn't cap the functionality.
David Chadwick concurs with this and noted that his current
prototype doesn't cover Multiple Resources, but that this isn't part
of the Core spec.
should read David Brossard concurs...
Paul pointed out that the W3C is working to develop standardized
mechanisms for expressing RDF graphs and that XACML fits within the
scope of this work. Therefore the TC should consider building upon
that work. Alternatively, he offered that a "bridge" between XACML
and the W3C work may be developed.
Hal countered that direct association with the concept of "Semantic
Web" work may defeat the underlying driver for this project
(enhanced approachability of XACML).
Paul noted that he is not against any efforts to make XACML more
approachable in HTTP based environments.
XACML Implementers Guide
Rich reviewed his position on the ramifications of how the current
direction on extended Indeterminate response and what it may mean to
new adopters. This lead to the revival of the Adopters Guide. Rich
asked that the TC consider adding/updating content to the guide as
for changes to the spec/Profiles that have been added since the
guide
IV. New Issue
Permit|Deny Bias PDPs & Extended Indeterminate
Rich introduced and issue that was derived from comments by
Indeterminate (D|P) results need to be percolated up to the response
when generated by PDP bias.
Paul asked for clarification where Ind(D|P) would be applicable in a
real world example. He noted that and Ind(D) could not be converted
into a Permit. Rich offered that additional Attributes could result
in a N/A. Paul replied that this still doesn't result in a practical
Use Case. Rich suggested that the TC dig into Chapter 2 of the
Implementor's Guide to begin the clarification process.
Obligations/Advice combining ambiguities.
Rich asked for input on the current understanding on how Obligations
/Advices are combined in a deterministic manner. Hal reviewed the
historical context of the desire for unordered evaluation. Rich
will post a proposed solution to the list that is based upon the
concept of a "default" behavior, that is followed by a list of an
enumerated list of Obligations/Advices that are attempted.
