monica: if we look at a nested policy expression, ... look at definitions
14:03:21 [dorchard]
q+ to ask how ws-sp uses policy 1.5
14:03:26 [maryann]
since a nested assertion ( according to our definition) means that the behavior qualifies a parent assertion
14:03:59 [maryann]
then at some level the "empty" does imply a certain level of behavior since the parent or root is expressing some behavior
14:04:33 [dorchard]

felix: this would create versioning problems, and problems with proposal from ws-addressing
14:05:17 [cferris]
ack as
14:05:17 [maryann]
the nested could be additive behavior rather than exclusive behavior that might conflict if you tried to match an empty with a specific sub-assertion
14:05:30 [dorchard]
asir: go back to ashok's point that wildcard wouldn't break security policy
14:05:52 [Nadalin]
yes it would break SP
14:06:16 [asir]
Bottom of Section 3.9 http://www.w3.org/TR/2007/WD-ws-policy-primer-20070330/#nested-policy-expressions
14:06:23 [maryann]
i think it depends on the assertion
14:06:54 [Nadalin]
it would break anyone use of assertions
14:06:58 [maryann]
and the fact that these assertions were designed with an assumption about how the algorithm currently works
14:07:25 [dorchard]
asir: brings up httpstoken with parameters
14:07:33 [prasad]
Yes in general we cannot guarentee that a nested one would always match empty. In some cases it would and some cases it may not. Depends on the specific case
14:07:38 [dorchard]
ashok: no, that's domain specific.
14:08:00 [dorchard]
asir: if you have a nested policy, then it indicates any behaviour.
14:08:15 [monica]

cferris: don't buy the argument that if I added new extension then I'd get a false positive.
14:11:21 [dorchard]
cferris: in the case if I had all the options (ie security policy) then compare all those
14:12:05 [dorchard]
cferris: vs letting subsequent behaviour figure out cipher suite..

dorchard, you wanted to follow up on paul's rebuttal and to ask how ws-sp uses policy 1.5
14:13:14 [fsasaki]
dorchard: paulc was arguing against the wildcard proposal based on ws-security policy does
14:13:54 [fsasaki]
paulc: I looked at the ws-sx spec, you statement was wrong
14:14:00 [PaulC]
Charter text: Web Services Policy should remain compatible with existing policy assertions and offer a smooth migration path for these assertions (where applicable). Existing policy assertions (in specifications that have been submitted to other standards groups) are Web Services Reliable Messaging Policy, Web Services Security Policy, Web Services Atomic Transaction, and Web Services Business Activity Framework.
14:14:02 [Ashok]

14:14:09 [fsasaki]
dorchard: am I talking against an implementation or a WG?
14:14:18 [monica]
q+
14:14:19 [fsasaki]
paulc: reply is citation from charter text above
14:15:04 [fsasaki]
paulc: dorchard said "other TCs have gone ahead without policy, so we can do what the want". That is not true
14:15:21 [fsasaki]
.. ws-sx will reference also the CR version of policy
14:15:37 [fsasaki]
dorchard: how will security policy use policy?
14:16:05 [fsasaki]
.. what will the impact of the change be to security policy? It will break their current work, but they might benefit in the future
14:16:25 [fsasaki]
.. what is the compatibility issue?
14:16:33 [fsasaki]
paulc: go back to WD, change the NS
14:16:49 [fsasaki]
dorchard: they have a reference, but how is policy used?
14:16:56 [fsasaki]
q+
14:17:04 [asir]
q+
14:17:25 [fsasaki]
maryann: it is more than just a reference, it is deep in the spec
14:17:34 [fsasaki]

<break conversation for posterity> there are issues for security policy, when a service takes the option of wildcarding...the use case for the customer side is easier to illustrate.
14:33:47 [maryann]
when the service is the one doing wildcarding it becomes very difficult with all the extensibility points in security & security policy, to understand what the service is willing to do....
14:35:28 [maryann]
in some sense it would be asserting it could do "anything" that the customer would have in its own policy, and it would be difficult to see how this range of options would be determined, assessesed for interoperability
14:35:56 [maryann]
the customer "could" extend with tokens, that the service was not aware of
14:36:37 [maryann]
there would need to be more constraints on these extensiblity points

ashok: they also have charter to change policy reference(s) (1.2 and 1.5 CR) to policy 1.5 rec

Empty as wildcard has problems for nested policy, it woujld be better to define a standard wildcard, which can be put into scope for parent policy for which wildcarding is appropriate for matching. I believe wildcarding is not approporated for all assertions which have nested policy assertion types This could be addressed in v.next

(now discussing mail from dorchard above)
15:14:20 [fsasaki]
dorchard: tried to describe actual differences between 4 positions I see
15:14:44 [fsasaki]
.. in terms of requester / and provider and "pseudo set theory"
15:15:19 [fsasaki]
.. I had a single scenario to describe the differences
15:17:24 [fsasaki]
(dorchard describes the mail, agreement that the mail is correct until "Strict intersection yields no intersection.")
15:17:47 [fsasaki]
now discussing the part starting "There is a policy <Z/> ..."
15:18:08 [fsasaki]
cferris: there are two flavors of that: talking about assertion vs. behavior
15:18:24 [fsasaki]
dorchard: let's talk about assertions only now
15:18:27 [fsasaki]
cferris: ok
15:20:03 [fsasaki]
dorchard: nobody is proponent for 1. about "2. AIN Closed world flavour : "
15:20:14 [fsasaki]
asir: nobody advocates 2 now
15:20:17 [fsasaki]
cferris: agree

dorchard: for the purpose of this yes
15:23:19 [fsasaki]
ashok: question on 3: one use case: both provider and requester have published policies
15:23:45 [fsasaki]
dorchard: the scope here is the simplist possible case, somebody starts an HTTP connection and picks up stuff

q+
15:26:46 [fsasaki]
maryann: why the "will" column?
15:26:53 [fsasaki]
dorchard: client has an intersection result and it will do a,b. It is not a "MUST" because of the intersection
15:26:56 [Zakim]
+whenry
15:27:00 [fsasaki]
paul: so this is for the lax intersection case
15:27:08 [fsasaki]
dorchard: yes, for strict case the table is boring
15:28:05 [fsasaki]
.. will or will not is about the intersection, must and "must not" are about both requester and provider
15:28:27 [fsasaki]
.. so will and will not is about the requester only

15:43:30 [fsasaki]
cferris: important to see "who initiates the behavior?" that is different than requester / provider
15:43:51 [fsasaki]
.. I am only constraining the initator
15:44:17 [fsasaki]
dorchard: I don't agree
15:45:08 [fsasaki]
.. in a single interaction, a provider behaves as a response
15:45:30 [ArnaudM]
ArnaudM has joined #ws-policy
15:45:34 [fsasaki]
cferris: I am not constraining the behavior of a response
15:45:37 [whenry]
But how do you really feel?
15:46:15 [maryann]
there is a bit of a passionate discussion happening live
15:46:27 [maryann]
for those of you remote, we ask your tolerance
15:46:44 [fsasaki]
(problems of following the discussion for remote participants, paulc says nothing we can do about that in the current discussion)
15:46:45 [monica]
q+
15:46:45 [maryann]
and we will try to capture the discussion in the scribed text
15:46:55 [whenry]
May need to change the rating to "R" ;-)
15:47:49 [fsasaki]
dorchard: what are the behaviors in the follow up of an interaction?
15:48:03 [fsasaki]
paulc: cferris says the interaction does not constrain the provider
15:48:19 [maryann]
chris does not believe that the intersected alternative constrains the provider behavior
15:48:47 [maryann]
david seems to have a different view of the behaviors for either party
15:50:08 [maryann]
david had tried to reduce the behaviors to a common set and chris feels the distinction is relevant and hence the reduction loses some characterization of behaviors thats important to capture
15:50:22 [fsasaki]
dorchard: in the policy framework, there is no constraint on the provider whether it must do D (from cferris perspective)
15:51:00 [fsasaki]
cferris: in the policy framework , there is no mechanism to tell which alternative I choose
15:51:56 [fsasaki]
.. I'm trying to make a statement in the spec to make clear: if I know what an assertion means in terms of its behavior, and it is not in the alternative selected, it will not be applied
15:55:10 [fsasaki]
paulc summarizes:
15:56:10 [fsasaki]
paulc: requestor will exibit a,b,c and must not do E. Z,Y,C,D are out of scope
15:56:42 [fsasaki]
(proposal is not on IRC)
15:57:21 [fsasaki]
paulc: using intersection means "there is an entity that initiates the intersection", in cferris proposal
15:57:36 [fsasaki]
.. if messages are going in the other direction, roles are changed

commutivity applies because policies are unordered

paul: normal form doesn't have a definition, it points to section 4.1 .....used the hyperlink to show the rules, isn't that what you want
17:33:22 [maryann]
david: i think its all in there someplace, but as a newcomer is its hard to find
17:33:39 [maryann]
paul: its a backward reference so maybe that was wrong
17:33:57 [maryann]
paul: and there is no definition and that phrase is used quite offten
17:34:12 [maryann]
paul: david is asking for a motivation
17:34:30 [maryann]
david: it says the intent is to facilitate interoperability
17:34:51 [maryann]
david: really what it does is ground the mapping from expression to policy
17:35:12 [maryann]
david: section 4.1
17:35:24 [maryann]
where it defines the element
17:35:48 [maryann]
david: not clear that putting out all lines in a normal form makes things simpler
17:36:09 [maryann]
paul: it says should
17:36:23 [maryann]
paul: and if you have a long policy that's a good reason
17:37:27 [maryann]
david: here we're saying that you will have to deal with non-normative expressions, the motivation seems odd
17:38:42 [maryann]
david: i think we've hit most of the points
17:38:52 [maryann]
chris: i think the group understands your concerns
17:39:23 [PaulC]
Consider changing: The following rules are used to transform a compact policy expression into a normal form policy expression:
17:39:39 [maryann]
chris: hopefully if you could express some suggested changes in the form of " please do x, y , z" ...preferably not a chinese menu :-)
17:39:41 [PaulC]
to inlcude a reference to 4.1 for "normal form policy expression"
17:40:00 [maryann]
chirs: WG is willing to entertain improvements

http://lists.w3.org/Archives/Public/public-ws-policy/2007May/0007.html
17:41:49 [maryann]
chris: this thread led to the realization that your terms and asirs terms are consistent
17:41:50 [PaulC]
and to include a reference to 4.3 for "compact policy expressions"
17:42:05 [maryann]
david: yes, there was some discussion back and forth
17:42:22 [maryann]
david: so i understand that "a" is different from "a,a"
17:42:52 [maryann]
david: alternatives that come out of intersection are going to be different than alternatives that come in from either side

17:42:53 [Zakim]
On the phone I see Nortel-Ottawa, Dave_Hull, whenry, Charlton_Barreto
17:44:24 [maryann]
david: there is no requirement that a policy be reduced to a policy with only one alternative
17:44:52 [maryann]
david: policies have set semantics and alternatives have bag semantics
17:45:18 [TRutt__]
q+
17:45:20 [maryann]
chris: this is a general issue
17:45:37 [maryann]
david: i think the ambiguity is gone from the text
17:46:21 [maryann]
chris: 4552, policies are sets not bags,
17:46:57 [maryann]
chris: there's a proposal from asir, to add text
17:47:11 [maryann]
david: if that's what you want to say, yes
17:47:21 [maryann]
asir: yes that's what we want to say
17:47:53 [fsasaki]
see mail http://lists.w3.org/Archives/Public/public-ws-policy/2007May/0062.html from asir
17:50:26 [maryann]
paul: the code that needs to know about different parameters is not in our hands
17:50:54 [maryann]
paul: you can't tell at intersection that they are the same
17:51:08 [monica]
q+
17:51:22 [maryann]
davidO: in owl you can say two things are the same
17:51:57 [maryann]
david: you can tell if you have two assertions are spelled exactly the same
17:52:07 [maryann]
david: same infoset
17:52:44 [maryann]
david: doesn't mean same infoset it means same assertion
17:53:04 [maryann]
paul: what benefit do i get from eliminating duplicates?
17:54:20 [maryann]
ashok: the algorithm is that they take the alternatives and they pull out the assertions and they apply the same thing twice, like encryption
17:54:42 [asir]
q+
17:54:56 [maryann]
david: seems like the use case doesn't give the result ( in the primer)
17:55:38 [dhull]
It seems that in most use cases it doesn't matter exactly what result comes back, just that it comes back at all
17:55:53 [maryann]
chris: we're sliding into the weeds......we could argue about whether polcies should be bags or sets of alternatives, i think it only matters that it might be simpler
17:56:06 [maryann]
chris: we have a proposal for a clarification
17:56:27 [maryann]
chris: so david, are you satisfied with that?
17:56:31 [maryann]
david: yes
17:57:07 [maryann]
david: given that the group has discussed this and said they're ok with it, then i'm ok with it

david: i might consider "aggregation" or some other term
18:14:47 [maryann]

Intersection is a commutative function that takes two policies and returns a policy.

New text:
18:20:58 [cferris]
Policy intersection is communtative operation performed on two poilicies that yields a policy that comtains a collection of the compatible policy alternatives. (Note: while policy intersection at times is analagous with set intersection, it does not imply formal set intersection semantics)

TOPIC: Issue 4544: policy vocabulary, will not be applied, oh my! Chris Ferris (11:00 am ET)
18:34:53 [maryann]
DavidO- would like to explore the open world
18:35:28 [maryann]
DavidO- this proposal is close to the one called "open world"
18:35:42 [maryann]
DavidO- I've had some trouble with the terms
18:36:26 [maryann]
DavidO- so i'd like to run through this on a more complicated message exchange
18:37:06 [maryann]
DavidO- terms initiatior is this protocol or wsdl in message
18:38:16 [maryann]
taking the Open world from the text proposed from David .....must do what is intersected and that's it
18:39:01 [maryann]
ashok: open world says nothing about what you must not do
18:39:34 [maryann]
david o - you said you can't live with this
18:40:08 [maryann]
chris-- the term "optional" means that there are two alternatives, not that the behavior is optional
18:40:57 [maryann]
davido- the requestor says RM optional
18:42:06 [maryann]
chris- its a matter of being precise in the use of the optional
18:42:54 [maryann]
davido- i don't understand the stridency of your position
18:43:02 [whenry]
q?
18:43:51 [maryann]
davido- if the client choses to do something why is this so bad?
18:45:13 [whenry]
Can the speakers speak up please?
18:47:17 [monica]
q+
18:47:26 [maryann]
i'll ask william, sorry
18:48:45 [maryann]
chris =- i'm making a big deal because if i don't use wsp:optional and I only have alternatives, and I am able to just select things to do anyway, then it negates the value of providing explicit alternatives
18:49:01 [maryann]
davidO: under my definition that's fine
18:49:32 [maryann]
dale: why did you put Y under must not? ( to chris)
18:49:43 [maryann]
chris -- no i didn't that's david's option
18:49:59 [maryann]
paul: your point is that optional is a macro
18:50:04 [maryann]
chris: yes
18:51:29 [maryann]
paul: imagine the case you have 16 alternatives
18:51:34 [maryann]
( to david)
18:52:22 [maryann]
paul: and you get back the one that doesn't have "e" in it, are you expecting that you can go back and if you find "e" is in it you can
18:52:50 [maryann]
davidO: i think its foolish for a client to do that, but its not necessary in the spec to say that
18:53:16 [daveo]
q+ to say chris' point
18:53:23 [PaulC]
ack monica
18:53:33 [maryann]
monica: i'd like to hear from dale, because he raised these issues about open & closed
18:54:13 [maryann]
monica: there was a long dicussion in AT and they had a hard time characterizing their assertions because they didn't know how to represent it
18:54:36 [fsasaki]
s/AT/WS-TX/
18:54:51 [maryann]
davidO: i want to try to champion chris's point of view to prove that i understand it
18:55:22 [maryann]
daveO: the requestor has this policy and there might be a bunch of things that the provider does that it may or may not be able to do
18:56:03 [maryann]
daveO: in intersection, it explicitly asked whether E was a behavior to do
18:56:41 [PaulC]
ack daveo
18:56:41 [Zakim]
daveo, you wanted to say chris' point
18:56:56 [maryann]
daveO: if you add behaviors that you didn't get back in intersection then you are throwing out the value of intersection
18:57:34 [maryann]
monica: they had a conundrum and they came to a point where they only expressed what they were required to do
18:57:49 [maryann]
chris: if you can do what you want, what's the value of policy?
18:58:12 [maryann]
paul: we could define the syntax, but intersection has no value
18:58:37 [whenry]
+1
18:58:48 [maryann]
paul: its a contract, i'm going to get your policy and this is what i'm going to do as a result of that
18:59:29 [maryann]
daveO: I want to see this under a more complicated message exchange pattern, i don't know what an entity that engages in an interaction means
18:59:47 [maryann]
paul: you're going to do that make connection to someone
19:00:14 [monica]
q+
19:00:17 [maryann]
paul: then something comes back....its got to be going to something
19:01:15 [maryann]
chris: you already did from a reliable message connection ....from a web services perspective you already did policy intersection with paul to send them originally
19:01:39 [maryann]
chris: so you know what's going on here
19:01:50 [maryann]
chris: you are the entity engaging in that interaction
19:02:35 [maryann]
chris: conversely, asynchronously, paul;s going to send messages asynchonously and reliably
19:03:01 [maryann]
davidO- when you engage in an interaction, what do you mean?
19:03:08 [maryann]
chris: i have an endpoint
19:03:21 [maryann]
david: what about an endpoint with multiple messages
19:03:34 [maryann]
david: its the first one, that you're engaging in
19:03:46 [maryann]
chris: angels dancing on the end of a pin
19:03:58 [maryann]
chris: you want to know how do i talk to paul
19:04:09 [maryann]
chris: so you go and get his policy
19:04:21 [maryann]
davidO; how does this map to the subjects we define
19:04:38 [maryann]
paul: that's what attachment states
19:05:19 [maryann]
paul: if you have some at one subject or at another subject, that's the one you have to apply the algorithm on that subject
19:05:41 [maryann]
that why we have subject granuarlity in the policy subjects
19:06:00 [maryann]
chris: we would just like to not have subjectivity in what you can do
19:06:21 [maryann]
chris: if we say you can do a or b, we want it to be either a or be
19:06:25 [maryann]
s/be/.b
19:06:33 [maryann]
chris: not that you can do a and b
19:06:49 [maryann]
chris: we want it to have predictability
19:07:22 [maryann]
david O --- why say in the spec MUST not
19:07:28 [maryann]
chris- it doesn't say must not
19:11:43 [maryann]
paul: is the only question about the verb
19:12:52 [whenry]
What text?
19:12:58 [maryann]
paul: straw poll, how many people can live with the text "If an initiating entity includes a policy assertion type A in its policy, and this policy assertion type A does not occur in an intersected policy, then the initiating entity does not apply the behavior implied by assertion type A. If a policy assertion type Z is not included in the policies being intersected then the intersected policy says nothing about the behavior implied by the assertion type Z

19:19:56 [fsasaki]
paulc: example : I have always RM in my policy. So even if I get a intersection result that has not RM in it, I will try to do it
19:20:16 [fsasaki]
TRutt: could not live with SHOULD NOT
19:21:11 [fsasaki]
ashok: wants to have a stronger word than "does not", e.g. SHOULD NOT or MUST NOT
19:22:01 [fsasaki]
paulc: ashok does not want the flexibility in the spec. dave wants the flexibility. Tom is between ashok and dave
19:22:30 [maryann]
sure i can take it back felix
19:22:58 [maryann]
paul ( to tom) why did you vote that way?

19:24:13 [whenry]
Are there penalties for MUST NOT? What will happen? What's the point. Even if we have a MUST NOT people are open to try the great thing is it won't work.

preference 4- 1
19:25:53 [whenry]
I like 2 "does not" better - let the best practices handle the shoulds
19:26:39 [maryann]
paul- strong preference for 3 and no one "can't live" with 3, so this is consensus
19:27:26 [maryann]
monica: is "entity" sufficient?
19:27:36 [maryann]
chris- i need to think about it over break
19:28:11 [maryann]
dave: i like getting rid if initiating because it gets rid of a lot of issues
19:29:01 [cferris]
from the "whiteboard": If an entity includes a policy assertion type A in its policy, and this policy assertion type A does not occur in an intersected policy, then that entity SHOULD NOT apply the behavior implied by assertion type A. If a policy assertion type Z is not included in the policies being intersected then the intersected policy says nothing about the behavior implied by the assertion type Z.

From the primer - In another example, WS-Security Policy defines a sp:HttpToken assertion to contain three possible nested elements, sp:HttpBasicAuthentication, sp:HttpDigestAuthentication and sp:RequireClientCertificate. When the HttpToken is used with an empty nested policy in a policy expression by a provider, it will indicate that none of the dependent behaviors namely authentication or client certificate is required. A non-anonymous client who require

CR requirements are about (not) breaking existing implementations, adding a new qname would be against that

The spec should clarify that the use of domain specific intersection processing requires that it be specified with the assertion type definition, In the lack of any domain specifric processing for intersection in the definition of an assertion type, the default intersection processing applies. If the intersection processor has to have a escape table (based on qname) for assertion types wanting to pull parameters into the algorithm, it costs no more

if any spec defines an assertion type with domain specific processing, the implementation of that spec has to have a way to "overide" the default processing for that assertion qname. This can be very costly.
