Administrivia RSA InterOp Status - review conference highlights * RSA interop - members comments good. rich: mentioned that the Boeing contribution was extremely useful and demonstrated the concept of defining "standard attributes" as defined in the IPC Profile, which enables "integration" of all the backend resource documents under a common representation umbrella independent of the technological details of the documents and their repositories.

Ray: clarified that single type was to show general format for each media type, and when agreed, more types can be added as needed. - Hal: careful about versioning.

(since Erik sent regrets for today's mtg) III. Issues Core (minor typos/questions): Remove erroneous comma: http://lists.oasis-open.org/archives/xacml/201202/msg00029.html - Ray commented extraneous comma needs removal. Remove bold,italic: http://lists.oasis-open.org/archives/xacml/201202/msg00043.html - used "action" in an informal way. message 43. List of combining algs: http://lists.oasis-open.org/archives/xacml/201202/msg00041.html - Normative language is out of date. Ray good with Erik's suggestion. Reuse of rules/PAP: http://lists.oasis-open.org/archives/xacml/201202/msg00024.html - sec 2.2; Ray; having rule ref; policy was the center of administration. - language is hold over from previous version. - Hal: suggest removing "use of tools". Need consensus XACML v3.0 Open Items Issues list: http://lists.oasis-open.org/archives/xacml/201202/msg00001.html Issues discussions: Issue #3: Combining Algorithm Issue #4 Context Handler Ray proposal and follow-up comments: http://lists.oasis-open.org/archives/xacml/201202/msg00040.html - Hal: debate is about arch definitions; doesn't object to tighten up language. - ??? comment: Introduce new component; context handler can also add context values to request. - Paul: obligation and advise handling as separate. - Hal: context handler for formatting, etc...; lines drawn for logic. all definitions cover their respective responsibilities. - Paul? context is a bag of attributes, first attribute needs to be fully populated and not changed. - Paul& Hal discussed RAA of components. message 38 of Feb. Erik's approval for Paul’s wording. - Hal approves Paul’s suggestion on how to proceed. - ???; comments: 1.) can cause improbability issues. 2.) can context be extended at runtime? i.e.; obligation telling pep how to do it. - Hal; separate the obligation and advice handling issues from the general context handler architecture issue.; ...adding attributes at a later time. - Rich: context plays a part in profiles by taking req from a structure into increments to pdp. Missing: wording misses this. - Rich: what context needs to contain i.e. one collection of attributes per category. Definition in arch is loosely defined. - Paul: Doesn't seem complete in defining arch pdp components? - Paul: need to be clear about what is being done with each component of arch. - Paul: fix wording to cover some cases. suggests limited changes. Issue #8 Schema Anomalies ("choice element" or "Policy w no Rules") recent discussion focus on whether combining algs render issue moot: http://lists.oasis-open.org/archives/xacml/201202/msg00044.html - summarize: rich: existing schema is troubling i.e. zero rules - intent of allowing not clear; schema stands for now... don't want to impact things now, but still needs review. key issue: there is single schema group that collects unrelated concepts and ties them together in inexplicable ways - rules - variable definitions - combining parameter collection elements. - Hal: what guidance doe we provide with a policy with no rules; put everyone on notice on this to look. - Hal: may need to move to weekly meetings to wrap up issues like this.
