Attendance:

Pal Takasci-Nagy (BEA Systems)
Mark Potts (Talking Blocks Inc.)
Mark Little (Hewlett-Packard Co.)
Sanjay Dalal (BEA Systems)
Pyounguk Cho (IONA Technologies PLC)
Peter Furniss (Choreology Ltd)

James Tauber (Bowstreet Inc.)
Alex Ceponkus (individual member)

The meeting was quorate, as there are 18 members, and 14 were in attendance.

Pal Takasci-Nagy joined the meeting a few minutes late. It was not clear when the meeting started whether he would be able to make it due to illness, and in his initial absence it was agreed that Mark Potts would chair.

The main discussion revolved around a written motion submitted by Mark Little (HP) and seconded by seven other committee members, which had been circulated prior to the meeting on the main mailing list:

The Technical Committee confirms the scope as determined by the last San Jose face-to-face in late July and the subsequent quorate and minuted teleconference of 16 August, namely:

To define the interoperable messages to be sent between initiators and the factory, terminators and coordinators/composers, enrollers and superiors, superiors and inferiors (including the roles and responsibilities of sub-coordinators and sub-composers in a transaction tree), and the relationship of contexts and replies to application messages, plus facilities for recovery including message redirection, and compounding capability to allow one-shot optimization and one-wire topology. A concrete binding to SOAP and SOAP-with-attachments is included. Partial role-based conformance is defined.

and further resolves to close discussion on issues of scope in the interests of rapid adoption of the Committee Specification.

Seconders: Jim Webber (HP), Pyounguk Cho (IONA), Alex Ceponkus, Alastair Green (Choreology),
Peter Furniss (Choreology), Bill Pope, James Tauber (Bowstreet)

In the meeting Pal Takacsi-Nagy formulated a counter-proposal which had first been raised in embryo in the last conference call. This was not put in writing, but the key points were:

To revert to the original BEA proposal in the following respects, in the interest of simplicity, and based on customer's needs as demonstrated by market experience with BEA's customers: get rid of some of the actors, remove the coordination factory capability, only allow one participant per service, remove 2PC in favour of 1.5PC as described in the BEA submission, or at least make 2PC optional, and remove cohesion capability, leaving only atomic capability.

A lively and robust discussion ensued.

Mark Little (HP) formally moved that his motion be voted upon, and a procedural discussion followed.

The members of the committee were asked by the chair if they had any objection to moving to a vote on this proposal, taking note of the fact that some of the committee's members had not realized the full scope of Pal's proposed changes until he represented them in this meeting. The following members of the committee indicated that they were not happy with voting, or might not feel properly equipped to vote, at this meeting: Sazi Temel (BEA), Sanjay Dalal (BEA), Pal Takacsi-Nagy (BEA).

Mark Little again moved that the motion be taken, pointing out that a failure to decide at this meeting risked the danger of the next meeting being inquorate, thereby leaving the debate entirely in the air.

Alastair Green (Choreology) proposed that the following amended version of Mark's original motion be adopted:

Mark Little motion, with proposed amendment shown in italics:

The Technical Committee confirms the scope as determined by the last San Jose face-to-face in late July and the subsequent quorate and minuted teleconference of 16 August, namely:

To define the interoperable messages to be sent between initiators and the factory, terminators and coordinators/composers, enrollers and superiors, superiors and inferiors (including the roles and responsibilities of sub-coordinators and sub-composers in a transaction tree), and the relationship of contexts and replies to application messages, plus facilities for recovery including message redirection, and compounding capability to allow one-shot optimization and one-wire topology. A concrete binding to SOAP and SOAP-with-attachments is included. Partial role-based conformance is defined.

and further resolves to close discussion on issues of scope at the end of the next telephone meeting on Thursday 18 October,  in the interests of rapid adoption of the Committee Specification.

He motivated this compromise as ensuring that there was no possibility that any member felt that discussion had been unduly truncated, while also ensuring that the current majority position (and status quo ante bellum) would stand, with the authority of a recent quorate meeting, unless overturned at the next meeting in the light of intervening debate and consideration.

The amended proposal was put to a roll-call vote. Bill Pope lost cellphone connectivity before this vote was taken, but all the other members in attendance voted unanimously in favour.

The remaining decisions were agreed by general assent and the nemo contra principle.

That the specification draft have a short prefatory section, and that it be accompanied by an separate primer, motivating and explaining the purpose and features of BTP for a non-implementer audience.

Mark Potts volunteered to draft this, using material from the current spec draft, and Mark Little offered to help in this project.

Alastair Green stated that Choreology Ltd were formally submitting their 38-slide technical overview of BTP to the TC, thereby making it freely available, and offered to maintain it for the TC, to further assist in publicizing the protocol.

Peter Furniss stated work had been continuing on the specification, including incorporation of all the decisions on messaging at the last phone meeting but one, and that a 0.9 draft would be available by 19 October. It was agreed

That the following timetable be adopted:

0.9 draft specification submitted 19 October 2001
Comments in by 26 October 2001
0.95 incorporating comments by 2 November 2001
E-mail vote to be called 9 November 2001
All votes to be in by Friday 16 November 2001
Assuming appropriate level of support, 0.95 is turned into 1.0 and is published as an OASIS Committee Specification
Peter Furniss was asked to distil his recent mail on membership of the TC, and his records on prior telephone meetings into a note for the chairman on which members should be formally warned about non-attendance, and possible loss of membership.

The meeting closed after one and a half hours.
