Scribe: approval postponed
JM: we're meeting on the 4th and 5th of
March
... we'll have less than two full days
... suggesting to extend our telcons to 2 hours or add a new telcon
<sanjiva> +1 for extending this call rather than doing another one
<Ingo> I cannot stay longer.
JM: suggestions on extending the telcon time?
<Ingo> Start 20 minutes earlier?
Scribe: some people can't make it later, some have reservations about starting earlier
JM: let's shoot for two hours, arranging
agenda items according to people's availability
... the extension is only for February (until the f2f)
JJM: I added all the issues from the agenda into the issues list
SW: some issues might be handled via email
JM: we have to decide at the telcons, but yes some are easy
JM: can issues 75 and 90 be closed - moved to edtodo as editorial?
RESOLUTION: issues 75 and 90 closed - moved to edtodo as editorial
Scribe: issue 75 closed by becoming obsolete
... issue 79 covered by an action item
... issue 96:
SW: we don't have a concrete proposal yet
JM: will try to schedule this for a telcon
Scribe: issue 97: schema language for soap encoding
JM: will any proposal result in changes in part 1?
JK: not necessarily
Scribe: issue 104:
bijan: we might want to add OWL support to
appendix E
... I'll say yea or nay next week
Scribe: issue 109:
... people working on it
... issue 111:
JM: mostly rejected at the f2f, what say BEA?
YG: we want this issue open, but if the group is not interested...
JM: if you'd file a minority opinion, we'd like a concrete proposal on this issue, otherwise we could just close it
TJ: WSDL 2 is not same as WSDL 1.1, we made it easier
<sanjiva> +1 to what Tom said
YG: WSDL 2 is still not hitting the 80/20 in terms of simplicity
<umit> +1 to Tom
JM: how much effort are you (BEA) willing to put into this?
<sanjiva> (at least the part about how
WSDL 2.0 is much nicer than 1.1 .. not necessarily to the part about
how WSDL 1.1 was a random walk thru attributes and elements ;-))
... -1 to introducing an inlined syntax .. just pre-warning the IBM
position on this.
JM: issue 111 stays open, up to BEA to champion it
Scribe: issue 112:
YG: I made a proposal, it was not discussed
GD: I still haven't sent in my proposal
YG: let's discuss this more in the mailing list
JM: we discussed it at the Nov f2f, it just isn't well documented yet
GD: I'll get that done by the end of the weekend
JM: let's discuss this more in the mailing list
Scribe: some discussion about whether it's too late for such comments as BEA's
JM: we can't reject the comments, they are quite substantial
TJ: are we removing headers from the binding?
GD: I'd like to, but probably no, I'm going to make a proposal for headers in binding (set by f&p)
YG: can it be discussed in a smaller group? It might be productive...
<Philippe> Header task force?
JM: we can do a small informal TF, I don't want a full TF with its overhead
YG: I'll send a mail inviting for a chat
Scribe: RC proposed a solution making the value and constraint attributes into elements
GD: let's open an issue on simple-type property values
JM: are we ready to address this or is the
new issue a prerequisite?
... any objection to adopting Roberto's resolution?
GD: I prefer to attack the new issue first
RC: the reworking depending on the new issue result would be pretty minor
<sanjiva> General +1 for adopting trivial changes that close an issue ;-)
JM: so again, any objections?
JM: waiting for Jacek's opinion on this
<sanjiva> I vote that we close issue 98 by saying @style is single URI valued. SOAP 1.1 tried to do this with @encodingStyle and while it was cool in theory, it was never really used ..
PLH: no existing style was reused for HTTP
style
... we don't need multiple styles
dbooth: subset is not the only way to think
about multiple styles
... independent styles might be combined
SW: I think we should keep a single valued style attribute
<Roberto> +1 for a single style
YG: since combinations might become complex we should keep it a single style
UY: we can't guarantee that the styles won't
interact
... on the other hand a style combining other styles will not be
recognized as such
<dbooth> By "mutually exclusive" do you mean "contradictory" or "orthogonal"?
GD: styles are hints, multi should be no problem
JK: what happened to my removing style attribute proposal?
JM: next on the agenda
<umit> what I meant was orthogonal
JM: getting close to a poll
PLH: we haven't seen a usecase
UY: Glen has a point, processing would be straighforward
JK: the next issue could remove this issue altogether
UY: we're trying to solve a semantic problem
by changing the syntax
... Jack's proposal just changes the syntax, too
<prasad> Said, applying the 80-20 rule, the complexity of going from 1-many on the spec as well as the implementation impact concern, I like speak against the proposal
JK: styles can in fact be viewed as extensions and there can be multiple extensions on single things
JM: (not chair) explicit styles are
beneficial because a tool now know what this extension is meant to be,
even if unknown
... I don't see the composability problems, really
<sanjiva> Response to Jonathan's comment: agreed, but we're not precluding someone from doing that using an extension attribute. We should focus on things that we know a need exists .. this one is speculative. SOAP 1.1's thing was speculative too and no one used it.
UY: prefer strongly this order of the issues: first multi style, then removing style attribute
<TomJordahl> +1 to a single style
... +1 to Umits suggestion that we decide if we want multiple to be
allowed
... -1 to Jaceks proposal for an alternative style specification
<sanjiva> +1 to Tom's -1
UY: would every style have to invent a namespace?
Scribe: JK, JM: yes
UY: from the processing POV the style attribute is easier
<prasad> There is a difference here in leaving open extensibility pt. and specc'ing in multiple URIs to start with.
UY: I don't see the value of Jack's proposal
<sanjiva> So have we switched from the issue 98 to issue 113?
JK: the value is the removing of a term - an operation style
UY: I want to keep the style concept in WSDL
<sanjiva> +1 to Umit's opposition to JK's solution for issue 113
UY: I'm inclining now to allow multiple values of style
<Roberto> +1 to Tom's -1 (and Sanjiva's +1 to Tom's -1)
SW: Jack's proposal removes first-class support for RPC
<prasad> +1 to Roberto and apply the math accordingly to other+s and -s
JK: my proposal doesn't add complexity, it removes it
<sanjiva> Jack, @style is *not* an extension - that's a part of WSDL! We recognize that schemas may be structured according to certain rules and then recognizing that the "RPC style" is one (and the only) such important style that the WSDL group cares to define.
JK: it supports RPC in the same "first-class" way as the style attribute
<umit> +1 to Sanjiva, can I make it ++ ;-)
SW: do we have a specific scenario pushing this?
JM: HTTP binding style brought this discussion up, but it seems it's not necessary now
UY: Jack, do you agree that the style attribute is equivalent to your 113 proposal?
JK: almost, the style attr approach adds more information
POLL: issue 98:
Scribe: a) yes, have stye attr a list of
URIs
... b) no, keep a single URI
AV: a
SW: b
UY: a
PY: ?
<bijan> bijan: abstains, btw
Eric: a
dbooth: a
RC: b
<Ingo> Ingo: abstain.
pauld: a
TJ: b
JK: a
<yaron> abstain
<umit> correction: style is with multiple attribute values is equivalent to JK's proposal
PY: a
RESOLUTION: style attr gets multivalued
SW: can someone write this up?
<dbooth> +1 to JacekK
JK: suggest order is insignificant
<pauld> +1
<asir> +1
JK: it's a conjunction, an "and" logical operation
SW: I suggested originally that order be significant
JM: what's a tool do with that order?
UY: if it's about applying the styles, there
is a relationship
... if there are no relationships between the styles (if they are
mutually exclusive) order does nothing
dbooth: if it's unordered, the "restriction" is still doable by listing the URIs
JM: can we go with an unordered list?
RESOLUTION: style multivalues are unordered
JM: summarizes Jack's proposal
JK: with the previous resolutions, the proposal may be rejected
JM: any objections?
RESOLUTION: issue 113 closed with no action (rejecting the proposal)
<dbooth> +1 to sri lanka!!!
<Philippe> 17-18 May 2004
... AC meeting (co-located with WWW2004 conference, 19-21 May), New
York, NY, USA
JK: offering hosting in Prague
<dbooth> +1 to prague also!
SW: an option for IBM to host the May f2f in NY
