Time: 16:30 ET (GMT-0500) Tel: 513-241-0892 Access Code: 65998 I. Roll Call Voting Members: Crystal Hayes Richard Hill Mohammad Jafari Steven Legg Rich Levinson Hal Lockhart (Co-Chair) Bill Parducci (Co-Chair) Richard Skedd Danny Thorpe John Tolbert Qurom: 10 of 12 (83% per Oasis site) Approve Minutes: 21 March 2013 TC Meeting APPROVED UNANIMOUSLY II. Administrivia IPC/EC-US Profiles These have received sufficient number of Attestations to proceed to Oasis standards vote. John indicated that he was interested in taking that step. Hal noted that the next step will be to gather the appropriate documentation for submission. ITU-T Submission The vote to submit XACML Core v3.0 to ITU-T is currently at 10 votes and officially closes this evening. Oasis is working on the submission today to present to ITU-T. ANSI cross certification John asked that the ramifications of this were to XACML. Hal noted that this is more of something at the "Oasis Level" and should not have an immediate effect on the TC. Hal will discuss further with Oasis. REST Profile Bill noted that CS status vote is currently at 10 votes to approve. John asked if Attestations can begin. Hal clarfied that they may once the ballot closes and that there is no official request mechanism. The URL needs to be published on the doc server to generate Attestations however, this will be published at the close of the ballot. RSA 2014 Hal sent a note to Jane Harnad a few weeks ago stating that the TC is interested but unlikely able to get financial commitments by the end of the month. He will follow-up with her to determine what the current state of this is. XACML & JS Hal noted that Waterford Institute posted a paper of an XACML subset in Javascript. They are in the process of joining Oasis. Hal proposed that they have 30 minutes on next call to discuss, which was met with general consensus by the group. The Chairs will reach out to the authors to schedule the presentation. Danny asked if this work was representational or PDP implementation. Hal responded that he believes both, although only with a subset of the full specification. MAP Profile Richard reviewed MAP Profile. Trusted Computing group slated to release their work. He intends to release the XACML MAP Profile draft sometime soon thereafter. Richard proposed to invite a speaker from Juniper to discuss MAP, tentatively at the 5/2 meeting. There is general consensus to pursue this, schedule permitting. III. Issues Obligations and Combiners Steven summarized the current discussion thus: When 2 rules are applicable in an evaluation and one carries an Obligation while the other doesn't, the determination of how this is applied is not specified (non deterministic). He then reviewed the discussion the list and listed 3 alternatives being proposed: * Steven: concept of the Obligation & Advice Authority * Mohammad: extend current language for combining * David: leave the language as is (issue unmerited) Bill verified that the OAA proposal introduces reduces Obligation processing to the final Subject, Action, Resource, thereby stripping out potential Obligations conflicts gathered during rule processing. Steven clarified that the decision made by the Context handler would pass and additional attribute to the OAA indicating Action derived. Danny also voiced interest in this approach. Mohammad reiterated a point he made on the list describing the need for all contextual information to be passed to the OAA (and issues that may cause), to which Steven responded that he felt that case to be unlikely. Hall encouraged the TC to bring forth "real world" Use Cases that can be used as the basis for addressing the issue going forward. Hal further stated that he currently believes at least some of the issues being addressed by the OAA could be handled by moving Obligations higher in the Policy hierarchy. meeting adjourned.
