Review of Action Items

<dbooth> ACTION: Zulah and Heather to have proposed Management Note draft ready for WG to consider at next F2F [PENDING]

<dbooth> ACTION: dbooth to reference current semantics work (DAML-S, OWL-S) in discovery section [DONE]
... [Status/Discussion of "needed to declare victory" items]

Discovery (David)

<dbooth> I have not checked in the new discovery text.

<Mike> How do we put content into editors’ draft? Frank is traveling this week.

<Eric> I have some notes to add too.

<MikeM> I also have to check in some privacy text.

<Mike> New materials must be published by next Wednesday, so that people have them available before F2F.

<dbooth> ACTION: dbooth to check in new Discovery and Intro sections to CVS

<dbooth> ACTION: dbooth to remind editors to check in changes so that people can get the full current draft [DONE]

Intermediaries, SOAP/WSDL mismatch (Mike / Mike)

<Ugo> I sent response to Hugo’s message pointing out what I think is the basic disconnect between WSDL and SOAP Intermediaries. Hugo’s note is fine, but needs more emphasis on current disconnect.

<dbooth> WSD recognizes current mismatch. I will contact WSD again.

<DaveO> A problem statement needs to be put on paper before discussions can meaningfully continue.

<dbooth> ACTION: MikeM and Ugo to write up problem statement about SOAP intermediaries and WSDL

Security model (Abbie, Frank, Katia, Hugo)

<Abbie> I am working on it. I will send new text to the group next week.

<Zulah> I am working on management model, and I will prepare new draft by Wednesday next week.

<dbooth> ACTION: Zulah and Abbie to get together about security and management text

Privacy (Mike M?)

<MikeM> I sent the new text to the list. Text is pretty ready to be added to main document. Frank already reviewed it and rearranged text to fit latest document format.

<dbooth> Mike's privacy text: http://lists.w3.org/Archives/Public/www-ws-arch/2003Oct/0066.html

Overall clarity, consistency

<Eric> I have some notes on consistency that I am going to discuss with the editors group and then add.

<dbooth> ACTION: dbooth to make the diagrams narrower to fit on printed page

F2F agenda suggestions

<Mike> If you plan to attend by phone, please specify in registration form.

<dbooth> hao, will you be calling in?

<Hao> yes

<mchampion> ACTION: Chairs will ping Katia on status of OWL discussions at F2F

<Mike> The main focus of F2F will be on the items recently appearing on the agenda as number 4. Plus discussions on what is needed to bring the document to reasonable shape.

<Zulah> No chance I will be able to prepare the stake holder section part before F2F. I’ll need two hours for management presentation.

<mchampion> ACTION: Chairs will put 2 hours for management discussions at F2F

<Paul> One additional item for discussion could be the issue about service identifiers, i.e. URI vs. Qname, target resources, etc.

<Mike> That is not necessary for declaring victory.

<dbooth> That issue has already been discussed within WSD. Our corresponding action item should be dropped.

<Hao> I will send the use cases document to Hugo to format and check in before F2F

<Mike> If people cannot check in new text, send URL to the list in preparation for F2F.

Reliability, reliable messaging (Hao)

<Hao> I took definition from what was agreed during last F2F

<Roger> I disagree on definition. What we have now just defines what does not happen. It misses the intent of actually delivering the message.

<mchampion> "The goal of reliable messaging protocols is to increase the probability that both ends have the same understanding of the state of the transmission"
... Nah, that still falls into the trap Roger has pointed out.

<Roger> I sent two other ways of defining it to the list.

<dbooth> I agree with Roger’s second definition.

<Hao> I agree with the second definition too.

<dbooth> ACTION: Hao to incorporate Roger's proposed definition for Message Reliability
... Roger's proposed definition was:
... [[
... "Message
... <dbooth> reliability is the degree of certainty that a message will be delivered
... <dbooth> and that sender and recipient will both have the same understanding of
... <dbooth> the delivery status"
... ]]

<yinleng> Can we paraphrase it to "Message reliability is the common degree of certainty understood by both sender and recipient that a message will be delivered"?

<Mike> Reliability also relates to other aspects, e.g. transactions. Notion of service reliability.

<Hao> Also availability of server (management implication)

<mchampion> ACTION: Group should consider the various aspects of "web service reliability" and note any aspects that we haven't covered in one of the models.

List of Specifications

<Mike> No news on Daniel’s database. Probably he won’t be able to do it because of other responsibilities. Martin can start with Roger’s list, and Paul will add a few items.

<Eric> Main issue is with open standardization activites vs. those that are conducted under copyright.

<Mike> How about using the taxonomy from article I sent to the list? See http://weblogs.java.net/pub/wlg/582.

<DaveO> Open vs. closed is unclear in many cases. There are many different criteria for openness. I suggest we don’t categorize.

<Roger> I have to go. I agree with David that the distinctions are extremely difficult and murky.

<Eric> What is important is that control is not kept by single vendor, and standard work is done free of IP encumbrance.
