Media Type Description issues

<Marsh> http://lists.w3.org/Archives/Public/public-ws-media-types/2005Feb/0000.html

I18n issues related to media type stuff

discussion whether adding negotiation stuff into media type description is a good idea .. the basic requirement is description, not negotiation

<Marsh> http://lists.w3.org/Archives/Public/www-ws-desc/2005Feb/0066.html

"normalized value" means XML normalization not things like case equality .. so the spec needs to make that clear

considered editorial .. Umit will follow up

<Arthur> http://lists.w3.org/Archives/Public/www-ws-desc/2005Feb/0068.html

component model discussion .. talking about arthur's proposal to move properties have [in scope] kind of notion

<asir> +1 to the first part of Arthur's proposal

no objections to adopting arthur's proposal to consistify f&p for interfaces

<Marsh> http://lists.w3.org/Archives/Public/www-ws-desc/2005Jan/0060.html

<Marsh> RESOUTION: Adopt Arthur's proposal 2005Feb/0068

z notation starts with component model; so very direct mapping of say interface components to the z interface schema. Additional constraints become z variables, e.g., in scope properties and in scope features. Arthur is writing logical formulae for computing these. Question is whether to make these directly in the component model and thereby remove Arthur's fun of wriitng these formulae.

Advantage is that this makes it analogous to how the Infoset namespace stuff works.

Asir: not convinced [in scope] will really help

[lots of explanation of family hierarchies and how things are computed; sure sounded complicated]

<uyalcina> +1 to asir

<kliu> +1 to asir

glen: points out that it may be easier to have a method that computes

roberto: agrees with asir.

umit: agrees with roberto

<Roberto> +1 for fixing the interface component

<uyalcina> +1

<asir> +1 for fixing the interface component

daveO: wonders whether people want to keep the component model closer to the input syntax and have other stuff be addon functions on the component model

objection to dropping proposal to add inscope f&p? nope

proposal from arthur: un-flatten operations and faults in interfaces so that the component model only shows the ops that are immediately declared in the current interface and others have to be found by looking at the super interfaces

no objections to adopting arthur's proposal

<bijan> Where are the results?

<Marsh> http://www.w3.org/2002/09/wbs/34041/WSD_AppendixE/results

<bijan> Thanks!

<bijan> The Bijan Option Rules!

<asir> thanks Bijan

<bijan> You are quite welcome :)

<Marsh> ACTION: Marsh to appoint an editor to publish Appendix E as a WG Note. [recorded in http://www.w3.org/2005/02/24-ws-desc-minutes#action01]

<dbooth> Prevailing option: "Publish the material in Appendix E as a WG Note."

LC70 resolution: appendix E to become a note

<asir> http://www.w3.org/2002/ws/desc/4/lc-issues/issues.html#LC70

I have to drop off .. can someone else take over please?

see you sanjiva, I will pick up from here

<sanjiva> thanks Kevin .. bye

discussion on whether we should say something about parallel schema definitions

amy: why not

arthur: does that mean we allow two different schemas define a same Qname?

amy: if there are mulitple type definition in use, presumably you should have some semantics attached to help decide which one should be used
... we don't define that, not saying we can't

DaveO: does schema has the same problem that defintions of same thing in different place?

asir: don't know

jmarsh: we have explored that with wsdl1.1 and 20

arthur: each type system has its own element declaration component

jacek: it might be slight inconsistency

<asir> James Clark has a mechanism to mix schema languages - see http://www.thaiopensource.com/relaxng/nrl.html

what happens if one use element, another use owl attribute

we may say something in the spec that if there are mulitple pointers in the message to different schema declarations there might be problems

asir: we can make it simple by ruling out multiple schema languages

jmarsh: is that a desirable way to go?

asir: there should be only one schema pointer in use

jmarsh: there are a few options, postpone to f2f

<Zakim> dbooth, you wanted to propose we include a note in the spec saying that if someone combines multiple schema languages may be a problem, and we have not solved this problem.
