DEFERRED ACTION DISCUSSION
Steve RT: Burdett have offline meeting on baseline document. Issue has been raised.
Mischkinsky: Private meeting on an issues list is unusual.
Burdett: Need to discuss.
Burdett: Two potential submissions which have not been accepted - CommerceOne and Oracle. Make as much progress with something reasonable. Group then can review. Quickest way to make progress. Keep group small initially to fix problems.
Mischkinsky: Inappropriate for group.
Austin: W3C exits to get people to agree and approve of these things; small groups of representative is questionable.
Burdett: Think of alternatives.
Mischkinsky: Group is open to accept or not accept submissions.
Goland: Unfortunate this was discussed within the working group. Team get together on their own is up to them. That group can decide whether or not to accept, then evaluate. Goland: Nothing to debate without a submission.
Austin: Will wait for the submission.
Liu: Understand Oracle was working on submissions, as does CommerceOne.
Mischkinsky: Not quite accurate that Oracle is working on further submissions.
Liu: Are you withdrawing initial submissions?
Goland: Inappropriate to discuss meeting that has not happened.
Burdett: Leave his initial submission as is.
Burdett: Talk about a specification to base work on.
Liu: Agrees with Monica MartinÕs comments. We need to work on initial submissions to create a working document.
Liu: CommerceOne and Oracle may submit additional documents.
Mischkinsky: Ifs in these statesments. Are we deciding on a joint proposal is speculation.
Mischkinsky: Someone make a motion to adopt a base document.
Mischkinsky: This type plan historically does not work.
Burdett: Who's going to take the next step?
Mischkinsky: Meta plans waste time. Can't commit people to future actions.
Steve RT: Action in the minutes is badly worded. We failed to spot this and understand this fully. Burdett did what the action asked for.
Steve RT: Rewrite action?
Liu: With another proposal, members have a right to know about it.
Steve RT: Two contributions have been made; neither have been accepted.
Steve RT: How do the two contributions match up - Burdett comes back to group to show how to pull these two contributions together.
Mischkinsky: Actually nick should have an action to match the oracle proposal to the reqs
Monica: If this results in further contirbution great.
Steve RT: Propose two actions - CommerceOne and Oracle should separately match the two contributions to the requirements document.
Martin (Chapman or Monica): Do we have contributions?
Steve RT: Yes we do.
Steve RT: Agreement to invite the contributions into the process.
Chapman: david's match to requirements is at http://lists.w3.org/Archives/Public/public-ws-chor/2003Oct/att-0009/BurdettML_Requirements_Comparison.pdf
Liu: Two contributions can be withdraw, per Steve RT. If there is a withdrawal, what happens if we use the work in that submission?
Steve RT: Need W3C clarification.
Lafon: Contribution has been made by the group. If accepted, it is under W3C IPR policy.
Austin: WSCI is also a contribution.
Steve RT: Withdraw his comments that withdrawals can occur.
Steve RT: Need Oracle assessment similar to Burdett.
Chapman: Verified Oracle submission was accepted.
Fletcher: With contributions, we have a decision to make. What happens with third contribution and what is its relationship to the other two?
Fletcher: A subgroup could take two contributions and create a baseline document or wait for this group's output?
Chapman: We need to move on as we are time constrained.
Austin: A third alternative: the two submitters could go forth and come back with a combined, optimized submission, which may or may not end up in the 'final' language
Steve RT: Impossible to do without the guidance from the submitters.
Mischkinsky: Finish the requirements, use cases
Martin: What would you propose we do in the interim?
Chapman: the use cases need a lot of work
Steve RT: Need comments on the submissions.
Steve RT: Give more time to Oracle submission for group consideration.
Mischkinsky: Finish requirements documents and use cases.
Steve RT: Need spreadsheet from Nick Kavantzas. Team to ask hard questions.
NEW ACTION: Nick to provide spreadsheet matching OracleML to requirements
Steve RT: Will send his private comments to the group.
Back to process issue that Jeffm Raised under Usecases/Requirements
Mischkinsky: Group must agree to any inclusion in documents.
Steve RT: Group seems to agree with this.
Chapman: Tony's rewritten requirement at http://lists.w3.org/Archives/Member/member-ws-chor/2003Oct/att-0005/20030929_Contribution_to_W3C_WS_Chor_on_Transaction_Reqs.doc
Fletcher: Transaction requirements; document sent ot the groups. Need assurance of the outcome (mutual assurance for an economic commitment).
Fletcher: Use transactions for all the use cases.
Burdett: Unit of work
Burdett: If this message is received, that marks the start/end of a transaction.
Fletcher: Put things in that are appropriate for the choreography language.
Chapman: What is the definition of transaction?
Fletcher: He has a definition. Action to send a definition to the list.
Burdett: Choreography could be one or more transactions.
Fletcher: Typically a choreography is more than one transaction.
Chapman: Need to have clarity on what is the difference with choreography and transaction.
Chapman: what is the diff between a choreograhy and a transaction
Steve RT: Doesn't have a clear view - ACID or LRT.
Fletcher: Will provide a good definition.
NEW ACTION: Tony Fletcher will provide a good definition of transaction
Fletcher: Underneath there would be WS-T, WS-TXM, BTP below the choreography. At the choreography level, they are achieving the same thing.
Chapman: What is the abstraction level needed in the choreography language?
Steve RT: With a transactional boundary, what can I do that I could not have done before.
Fletcher: Conclusion to the interaction.
Fletcher: Knows what the outcome is.
Goland: Is this explicit or outside of choreography?
Chapman: In one submission, equates choreography and transaction boundaries.
Austin: Look at Furniss/Austin ideas brought up in the first meeting related to this issue.
Chapman: Discuss in further detail next week.
NEW ACTION: This agenda item to be placed back on the agenda for next week assuming a succinct definition of transaction (see action above).
Steve RT: Any other business?
Chapman: Don't forget pre-registration for Australia? Poll will be open until 13 October 2003.
