JM PING   2003-05-13: DaveO to send a motivating example for R131.

PENDING   2003-05-13: Jeffsch, Sanjiva, Glen, Umit, JJM to come up with a proposal to get rid with the message construct, and add programming hints.

<scribe> jeffsch: proposal for getting rid of the msg is on the table. the pending work is only to outline programming concerns with that

PENDING   2003-05-14: Kevin to contact Sanjiva and try to merge proposals.

RETIRED [.2] 2003-05-22: Jacek to see how test assertions could be expressed in RDF (and OWL in particular).

<scribe> ...discussion on embedding testable assertions in the XML spec of WSDL...
<scribe> ACTION: JM to see what language for testable assertions should be used by the editors.
<scribe> ACTION: Jeffsch to show how testable asssertions would look like.
* JacekK thinks RDF will not be usable easily for testable assertions in the spec or in WSDL schemas

DONE [.3] 2003-05-29: Jonathan to tell XMLP that the SOAPBuilders proposal looks fine.  Additional SOAP 1.2 features will be addressed in WSDL 1.2.

4.  Administrivia
  a. Welcome new member: Bijan Parsia, MIND lab
  b. July FTF [.1], RSVP for Wed dinner [.2].

<scribe> ...WG inclined to move the F2F out of Toronto. Raleigh is the likely F2F place...

<scribe> JM: up to the editors if they could do it...

7.  Using RDF in WSDL [.1].

[.1] http://lists.w3.org/Archives/Public/www-ws-desc/2003May/0076.html

<scribe> jacek: embed RDF statements using WSDL extensibility. other way to take semantics 
  info and use current RDF elements and add semantics section to WSDL (like types section)
<scribe> JM: new section is the slippery slope as it opens it to add sections for QoS, etc.
<scribe> jacek: yes, that is why extensibility way is preferred
<scribe> arthur: is RDF annotation or a separate doc?
<scribe> dbooth: both are legitimate
<JacekK> philippe, could you point me to the short syntax please?
<scribe> arthur: if we embed raw RDF in WSDL then current processors will do the job, if we 
  invent something it will be bad
<scribe> jaceck: new element is only the context for RDF statements
<Marsh> http://lists.w3.org/Archives/Public/www-ws-desc/2003May/0076.html
<Philippe> jacekK: it is called Basic Abbreviated Syntax: http://www.w3.org/TR/REC-rdf-syntax/#basic
<scribe> bijan described a scary way of embedding RDF in comments
<scribe> bijan: tools usially look for rdf:RDF
<Philippe> or rdf:Description
<scribe> arthur: it is reasonable to have an extra element
<scribe> jeffsch: it is a fairly high bar to add a new first class element
<scribe> jacek: the element is an extensibility element, we merely invented it here for RDF 
* bijan notes that he doesn't understand extensibilty/substitution groups stuff yet
<scribe> JM: just simply fix the WSDL schema to allow RDF elements where appropriate
<Marsh> not precisely my point - User will simply write a bit of schema glue to put RDF 
  elements in the right substitution groups.
<scribe> jeffsch: suggestion to write a simple glue to follow JM's proposal, and if that 
  cannot be done, then we need to revisit the substitution group thing
<JacekK> wsdl:rdfDescription is an extension, as much as soap:binding
<scribe> jeffsch: concern is that it need to be normative, and the lement has to define the 
  right semantics to match RDF. That means RDF changes, WSDl is broken now.
<scribe> JM: believes that RDF can be simply put in one of the substitution groups and that 
  is it
<scribe> jacek: it means we have to redifine somebody's element (semantics of that 
<scribe> jacek: the element has to be designed to extend the WSDL. Its semantics sould be 
  that way. For example xs:schema element is like that rigth now.
<bijan> http://www.w3.org/TR/2003/REC-SVG11-20030114/metadata.html
<scribe> jacek: if we provide URIs for all of our components than RDF statements can be 
  easily written in an external document, but ity may not be very useable
<bijan> That's how SVG embeds RDF.
* jeffsch wonders if Bijan has a pointer to where RDF is embedded in Adobe's format(s)
<scribe> JM: if a DSIG had to be embedde in WSDL it works fine. There is no need of 
  wsdl:siganrures or like that
<bijan> http://www.adobe.com/products/xmp/main.html
<bijan> Adobe Extensible Metadata Platform (XMP), how they embed RDF (and other things, i 
<scribe> jacek: wdl:rdfDescription is just for the context, still believes that
* jeffsch wonders if Bijan could do one more... example of a license in RDF in an XML 
<scribe> JM: underlying issue is if the substgrp mechanism is good and why not...
<scribe> ACTION: JM to see what is the problem with substgrps.
<JacekK> bijan, in the SVG way (<metadata>) do the RDF statements know their context?
<scribe> JM: there is more support to the extensibility element rather than new section
<scribe> jeffsch: push back on both of those, much prefer to see if it can be done by the 
  existing extensibilty mechanism
<scribe> jacek: the current proposal is to use existing ext. 
<scribe> jeffsch: concerned that we would be defining the new element (even for 
<bijan> http://www.xml.com/pub/a/2003/01/15/creative.html
<bijan> ARticle about creative commons embeding rdf in comments
<scribe> arthur: is it parallel with properties/features. the intention is just annotation 
  of the doc
<scribe> JM: seems like
<bijan> And one more: http://infomesh.net/2002/rdfinhtml/ all about rdf in HTML
<scribe> jacek: using RDF is similar to using P&F?
<scribe> arthur: yes
<scribe> JM: unification?...
<bijan> http://creativecommons.org/learn/technology/usingmarkup
<scribe> arthur: may be we can convery any property to an RDF statement. Define the rule to 
  do so.
<bijan> Actual cc page saying "put the RDF in an xml/html comment"
<scribe> jacek: yes, P&F can use RDF mechanisms, but not vice versa
<scribe> JM: we need o start working on the WSDL doc to RDF mapping

8.  Proposal: rationalization of faults in patterns [.1].

[.1] http://lists.w3.org/Archives/Public/www-ws-desc/2003May/0085.html

<scribe> JM: any reason not to adopt Amy's proposal?
<scribe> dbooth: strongly in favour
<scribe> jacek: are the rules visible in the WSDL doc?
<scribe> amy: no
<scribe> umit: why limit the patterns in any way?
<JacekK> what value does factoring fault rules out give us?
<scribe> JM: it is just an additional way to understand the patterns
<JacekK> does it simplify the text of the spec?
<scribe> JM: vendor's extension MEPs must follow the rules that we described
<scribe> JM: dbooth to drive the simplification
