Subject: Re: [xacml] Minutes for 7 February 2013 TC Meeting - updated

Dear all,

Apologies for missing this meeting. It skipped my mind and by the time I remember it was well too late.

Re. the JSON profile, Steven, I wasn't aware of the ID issue. I got your note re. arrays and that was that. Did I miss another email?

         refs to material (free) describing the PM:

 XACML RSA demo:
   john: boeing ready for tagging part
        stephen posted link
        have been working w nextlabs
        still not all people that are needed
   hal: boeing, oracle, uds, nextlabs were only ones on this wk's call
        only 2 more calls before interop - please send people to
        call so info is rcvd
   hal: oasis will make banner; kmip also put up a banner, company
        logo's connected in box w chains around it. Last year we
        showed components but not logos; open to suggestions to
        give to oasis by next wed.
   hal: slide deck from last yr needs some updates but should be usable;
        respond to email

III. Issues

 JSON Profile

   stephen: has minor chgs plus one thing on id's but has not heard
         from david yet

 Attributes of Relations

    hal: should we tackle these 2 issues
    erik: think we are converging on something; perf concern about
        large sets of tuples, stephen said could optimize by
        processing subsets; concern that xacml might be translatable
        to db searches;
    stephen: what should extensions actually look like, mohammad came
        up w sql-like approach; in condition implicitly selects, and
        need diff syntax for joins;
    mohammad: thinks a simple join will work
    stephen: tuple sets soon has duplication within nested context;
        because of that abandoned nested;
    rich: wants to mention that sql not a good representation, should
        be more like attr-val-entity;
    stephen: agrees in general
    mohammad: agrees but when tried to extend hier ran into issues and
        thats when sql emerged.
    rich: will try to elaborate in followup email

 Policy Labeling

   stephen: still looking into alternatives to admin approach; practical
        necessity to dup admin policies nearly everywhere there is issue
        wrt unsafe policies being integrated w admin policies; reduction
        graphs lead to some perf issues
   erik: fwd chaining doesn't have same problem; top down recursive
        could limit intermediate delegates;
        also issue w np-complete;
   stephen: hasn't found way to deal w malicious policy;
   hal: in old days disc about detecting invalid policies;
   hal: recollection of use cases; large ratio between general pop
         vs admin people; maybe that helps;
   rich: what is issue of ctl
   stephen: sibling admin policy; writer of admin has to anticipate
        places where delegates will be extending, and making
        sure delegates have right authority; only sibling within
        same policy set.
   hal: as opposed to putting admins high in the tree;
   stephen: but hi in tree can't authorize things lower in the tree;
   stephen: one interesting use case is discretionary access ctl, such
        as every owner of resource is authorized, so they can write
        policies for their own resources;
   hal: "can do, can del" was intended to address that; if you are allowed
        to do it, you can delegate it as a policy; originally was in
        admin profile but we moved it to core.
        "can do, can del" is popular access model, implicitly mentioned
        in sections 2.7, 2.9 of core spec.

 Other business:

  hal: next call in 2 weeks 21-Feb-2013

  meeting/call adjourned: 3:51PM 7-Feb-2013
