<JacekK> ACTION: Laurent to send some proposal for "partial SAWSDL files" in relation with LC issue 13 [DONE] [recorded in http://www.w3.org/2002/ws/sawsdl/minutes/20061212#action06]

LC issue 13: external annotations

Issue 13: imported schema to included schema a proposal by Karthik

another proposal from Laurent

Karthik: schema can be own by third party, how can probably have an annotation to the external schema
... xpath expression could be used for that purpose
... on going work... can come up with a concrete example later on

Jack: the spec external annotation could be published as a separate document
... we don't have mandate to include external annotation in this document
... but this could have negative impact on the visibility of the document and the external annotation mechanism

carlos: do we know any other similar situations?

holger: how long will it take get through the process if we add external annotations to the spec?

JacekK: excluding the holiday, it will take something like one and half month (i.e., it would delay our CR by that time)
... looking at the mechanism, putting external model reference at schema components would be a better alternative
... the annotation is really on components, not the emlements

<holger> if of interest the pointer to mail msg

<holger> http://lists.w3.org/Archives/Public/public-ws-semann/2006Dec/0012.html

sdaume: how effective this approach is going to be? I would not push this approach for the spec

ericP: motivation for external annotation is that the annotated document might change

Joel: people have a feeling like SAWSDL will provide strong control about the life-cycle of a WS

sdaume: depending on different requirements for annotating interfaces, external annotation might be useful

JacekK: xpath is not quite useful as a means of indentifier
... let's see what preference we have

<JacekK> chad, new poll

<chad> new poll

<JacekK> chad, option 1: quick, recommending RDF

JacekK: we can recommend RDF and/or XSLT/XQuery for annotating external files, the first on the component level, the second on the XML attribute level

<JacekK> chad, option 2: outside our spec, pursuing either of existing proposals

<JacekK> chad, option 3: inside spec, pursuing either of existing proposals (delay before going to CR)

<JacekK> vote: 1, 2, 3

<ericP> vote: 1 2 3

<holger> vote: 1 3 2

<caribou> vote: 1 2

<sdaume> vote: 3, 1, 2

<carlos> vote: 3 1 2

<Joel> vote: 1, 2, 3

<brahmananda> vote: 1 3 2

<lhnocque> vote:3 & 2

<JacekK> vote: lhenocque: 3, 2

<lhnocque> vote: 3 1 2

<JacekK> chad, count

<chad> Question: unknown

<chad> Option 1: quick, recommending RDF (6)

<chad> Option 2: outside our spec, pursuing either of existing proposals (0)

<chad> Option 3: inside spec, pursuing either of existing proposals (delay before going to CR) (5)

<chad> 11 voters: bns (1,3,2),caribou (1,2),carlos (3,1,2),claudio (3),ericP (1,2,3),holger (1,3,2),JacekK (1,2,3),Joel (1,2,3),lhenocque (3,2),lhnocque (3,1,2),sdaume (3,1,2)

<chad> Round 1: Count of first place rankings.

<chad> Candidate 1 is elected.

<chad> Winner is option 1 - quick, recommending RDF

JacekK: would RDF option work for everybody?

<caribou> /me notes Laurent voted twice :)

lhnocque: not sure how RDF can be used in this case - I imagine something that takes the original document, the document with external annotations and turns it into an annotated document

JacekK: this can already be done very easily with XSLT, for example

Karthik: agrees with the proposal, RDF would probably work

RESOLUTION: LC issue 13: we will add text that recommends RDF or XSLT for external annotations, nothing too normative

LC issue 17

carlos: if we are using RDF, do we imply some how that a property called SAWSDL model reference?

JacekK: we are doing that already
... the suggestation is to add two RDF properties... sawsdl lifting/lowering schema mapping

RESOLUTION: LC Issue 17: we will declare two RDF properties for lifting and lowering schema mappings

CR criteria, publication

JacekK: sent two emails regarding list of SAWSDL features and the CR criteria
... list of features: http://lists.w3.org/Archives/Public/public-ws-semann/2006Dec/0011.html
... cr criteria: http://lists.w3.org/Archives/Public/public-ws-semann/2006Dec/0013.html
... are we defining features normatively other than this?

Joel: do they cover interoperability concerns?

JacekK: formally it does, W3C does not require two interoperabile implementations
... we can test parsers against some annotated WSDLs

ericP: they seem quite satisfactory from W3C point of view :-)

JacekK: tomorrow close of business we will have stable spec for review
... please review and cast your vote in the questionnaire at http://www.w3.org/2002/09/wbs/39001/readyForCR/
... no answer implies ''agreed''
... usage guide will be published together with spec
... last remaining agends are left for January phone call
