Review of Action items [.1]. PENDING 2003-03-13: Don will write a proposal for annotating schema with part information. PENDING 2003-03-27: Philippe write up a proposal for embedding binary data types in schema DONE 2003-05-12: Jonathan to work on auto generating pseudo-syntax from schema. DONE [.4] 2003-05-13: Umit to write up a variant of the endpoint description proposal using schema annotation syntax. 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.

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... <dbooth> Our minutes should note that no one objected to moving the F2F to Raleigh. <scribe> no one objected to moving F2F to Raleigh :) c. Vote to publish new parts 1, 2, and 3. [.3, .4, .5] <scribe> JM: vote to publish parts 1,2,3 <scribe> JM: major new work was on HTTP binding <scribe> no objection from WG to publish <scribe> ACTION: editors to publish 1,2,3 <scribe> jeffsch: primer has to be synched up with the spec and published as well <scribe> dbooth: it's been hard to keep up with the spec so far <scribe> JM: there are other outstanding structural items: Grid attributes TF, etc. <scribe> JM: up to the editors if they could do it... [.1] http://www.w3.org/2002/ws/desc/3/05/f2fJulyLogistics.htm [.2] http://lists.w3.org/Archives/Member/w3c-ws-desc/2003May/0049.html [.3] http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl12/wsdl12.html [.4] http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl12/wsdl12-patterns. html [.5] http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/wsdl12/wsdl12-bindings. html ------------------------------------------------------------------ 5. Task Force Status. a. Properties and Features <scribe> JM; what's the mission? <scribe> glen: roll the discussions into the WG and leave the other part to WSA WG. <scribe> JM: TF is dormant then... <scribe> glen: yes b. Patterns <scribe> dbooth: refined the notation and terminology c. Attributes [.1] <scribe> requirements, deliverables were discussed <scribe> joint TF between OGSI and WSD WG <scribe> JM: more participation from other groups is via the public maillist <scribe> JM: the objective of the TF is to prepare to sell the attributes/state to the WSD WG d. QA & Testing [.1] http://lists.w3.org/Archives/Member/w3c-ws-desc/2003May/0030.html ------------------------------------------------------------------ 6. New Issues. Merged issues list [.1]. - <documentation> not attribute-extensible [.2] (Jonathan) [.1] http://dev.w3.org/cvsweb/~checkout~/2002/ws/desc/issues/wsd-issues.html [.2] http://lists.w3.org/Archives/Public/www-ws-desc/2003May/0092.html ------------------------------------------------------------------ 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 statements * 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 element???) <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 believe) <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 comment? <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 extensibility) <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 TIME IS UP, TELCON IS OVER
