Mr. Minot apologized for being able to attend only on 15 April, and Mr. Dawes accepted with thanks to Chair the meeting on 16 and 17 April. Mr. Davis apologized for his own partial attendance at this meeting, travelling early this week to other business in Japan. An attendance list is given at annex A to these minutes. Apologies for absence were received from Prof. Dr. Kelter (Germany; other commitments this week), Mr. Simonsen (Denmark; delay in Japan compounded by commitments at a concurrent meeting in København), and Mr. Yoshino (Japan; otherwise engaged in completing an important repository development project), all indicating that they will keep in close contact with current WG22 business via email. These minutes cover both the WG22 4th meeting and the joint sessions with ECMA TC33 held during 15-17 April; items covered in joint sessions are indicated as such in these minutes. 2 Adoption of agenda The agenda was adopted as proposed (WG22 N75), after adding a new item 14 on a PCTE query facility, and is reflected by these minutes. A number of items were re-sequenced to take account of partial attendance by some members this week. 3 Approval of minutes of WG22 3rd meeting The minutes, including annexes A, B and C, were approved as written (WG22 N65, Makuhari, Japan, 13-15 November 1995). 4 Review of actions The status of all open actions from previous minutes was reviewed (summarily given at annex C of WG22 N65). Four organizational points (actions 3.20, 3.21, 3.22 and 3.23) were immediately noted as discharged, with thanks to Mr. Dawes and BSI for the fine arrangements made in London. All other open actions from previous minutes were reviewed under appropriate items of the present meeting : Action 1.11 : addressed under item 18; Action 1.12 : addressed under item 18; Action 3.1 : addressed under item 6.4; Action 3.2 : addressed under item 6.7; Action 3.3 : addressed under item 10; Action 3.4 : addressed under item 10; Action 3.5 : addressed under item 12; Action 3.6 : addressed under item 8; Action 3.7 : addressed under item 8; Action 3.8 : addressed under item 8; Action 3.9 : addressed under item 9; Action 3.10 : addressed under item 9; Action 3.11 : addressed under item 13; Action 3.12 : addressed under item 17; Action 3.13 : addressed under item 18; Action 3.14 : addressed under item 16; Action 3.15 : addressed under item 16; Action 3.16 : addressed under item 7; Action 3.17 : addressed under item 19; Action 3.18 : addressed under item 19; Action 3.19 : addressed under item 19. A summary of all carried-forward actions is given at annex C to these minutes. 5 Reports from national bodies Mr. Dawes gave a brief oral report on news from the United Kingdom. No news was reported from other nations. 6 Review of liaisons with other groups 6.1 SC7/WG11 - SEDDR (addressed in joint session with ECMA TC33) Mr. Davis introduced his liaison report to WG22 on PCTE Schema Definition Sets (WG22 N106), and a mapping strategy for deriving PCTE SDSs from CDIF subject areas (WG22 N107). Mr. Davis then introduced an extract of the CDIF integrated meta-model Common subject area (WG22 N108), and PCTE SDSs for four CDIF subject areas : Common (WG22 N109), Foundation (WG22 N110), Data Modelling (WG22 N111), Data Definition (WG22 N112), adding that there should not be an ICL or CDIF copyright on these papers. Mr. Davis proposed in a broad manner that the four PCTE SDSs be progressed with a view to publication as ECMA standards, possibly in a December 1996 timeframe, and that the mapping strategy for deriving PCTE SDSs from CDIF subject areas also be envisaged for publication by ECMA in December 1996, as a TR or standard. All members of WG22 and ECMA TC33 present viewed the papers prepared by Mr. Davis in a highly positive manner and expressed support for his initiatives and work, as recorded in Resolution 4.1 (in annex B to these minutes). It was agreed that comments should be forwarded to Mr. Davis : from WG22 members in regard and support for the work within SC7/WG11, and from ECMA TC33 members in regard and support for their progression to ECMA publications. Action 4.1 : Mr. Dawes To study what if anything needs to be done in using DDL to define standard SDSs. Status : new 6.2 SC21/WG3 - Database Liaison officer Dr. Bird indicated that there is no news to report at present, other than noting the outcome on repository standards issues from the recent JTC1 Sydney plenary meeting (document WG22 N104 refers, considered in item 7 below). 6.3 SC22/WG9 - Ada Liaison officer Mr. Dawes indicated that there is no news to report at present. 6.4 SC22/WG11 - Binding techniques Liaison officer Mr. Dawes indicated that WG11 are meeting this week in København; there is no news to report yet. Action 3.1 : Mr. Dawes To provide WG22 with a copy of a draft from WG11 on guidelines for the production of language-independent service specifications. A first complete draft may already be available. Status : carried-forward 6.5 SC22/WG14 - C and SC22/WG15 - POSIX and SC22/WG20 - Internationalization No specific actions were seen as necessary at present (but see action 4.4 under item 8 below). 6.6 ECMA TC33 (addressed in joint session with ECMA TC33) The minutes of the 36th meeting of ECMA TC33 held in November 1995 in Makuhari were noted as circulated (document WG22 N66). No specific items needed to be addressed this week that were not covered elsewhere on the agenda. It was noted that Mr. Dawes had been appointed as Chairman of TC33, replacing Mr. Minot. Accordingly WG22 unanimously appointed Mr. Dawes as liaison officer from WG22 to ECMA TC33, replacing Mr. Minot. This was recorded in Resolution 4.2 (in annex B to these minutes). Appreciation was expressed to Mr. Minot for carrying out the liaison with ECMA TC33 in a first-rate fashion over the past two years (applause). 6.7 OMG It was recalled from earlier initiatives that the OMG wish to apply for a Category C liaison status in SC22 (documents WG22 N47 and N48 refer), and that an action had been taken to move forward : Action 3.2 : Mr. Davis To progress the mutual benefits document required for SC22 and JTC1 approval of Category C liaison status for OMG in SC22 with regard to WG22. Status : not done (Mr. Davis apologized for not progressing this action, now superseded by new action 4.2 below) Action 4.2 : Mr. Minot To update the OMG liaison text for SC22/WG22 (WG22 N48) and send it to Dr. Jon Siegel, Director Domain Technology at OMG, with advice on how to proceed in obtaining Category C liaison status for OMG in SC22 with regard to WG22, if OMG interest is maintained. Status : new 6.8 Other news (addressed in joint session with ECMA TC33) It was noted that a JTC1-sponsored joint workshop on standards for the use of models that define the data and processes of information systems is to be held in Bellevue, Washington State, USA in September 1996, and that WG22 is invited. Some initial information on this workshop was provided (WG22 N102). With regard to point 4 of the SC7/WG11 liaison report to WG22 on PCTE Schema Definition Sets (WG22 N106), WG22 welcomed and appointed Mr. Davis as a representative to the joint workshop. This is recorded in Resolution 4.3 (in annex B to these minutes). It was also agreed to take a broader and more general action in regard to the workshop : Action 4.3 : Mr. Minot To contact those responsible for arrangements for the joint workshop, and advise the interest and wish to participate from WG22 and to pre-register all WG22 members present. Status : new 7 Follow-up of answer to JTC1 on repository standards issues Action 3.16 : Mr. Dawes, Dr. Bird, Mr. Minot To prepare the proposed final-form response on the repository standards issues and send to the SC22 Chairman for onwards forwarding to JTC1. Status : done (WG22 N76) Mr. Dawes and Mr. Minot reported on subsequent developments. The proposed joint SC21/SC22 position on repository standards work prepared following the previous meeting in Makuhari last November (WG22 N76) had been duly onwards-processed, resulting in a joint position of the SC21 and SC22 Chairmen as agreed at the recent JTC1 plenary meeting in Sydney, Australia (WG22 N104). Appreciation was expressed to all who had contributed to achieving this highly satisfactory result. Members interested were referred back to earlier papers and events (WG22 N10, covering documents SC22 N1786, JTC1 N3397, JTC1 N3162, and SC21 N8906, also item 11.1 of the SC22 Annapolis plenary minutes WG22 N57). 8 Follow-up of request for project subdivision for IDL binding (addressed in joint session with ECMA TC33) Action 3.6 : Mr. Brockway To request SC22 approval of a new sub-project JTC1.22.47.5 for the IDL binding, giving explanatory rationale, and to express concern that SC21 had not advised the existence of the IDL CD 14750 ballot. Status : done (SC22 ballot currently in progress, with an end-date of 26 May 1996; document WG22 N81 : SC22 N2030 refers) It was noted that publication by ECMA of the IDL binding, as Standard ECMA-230, had been delayed due to the need to complete final editorial work and further communicate with the OMG in regard to freedom of copyright. These actions now taken as complete, TC33 agreed to publish ECMA-230. Action 3.7 : Mr. Brockway To circulate Standard ECMA-230 to WG22 and SC22 as a document for information purposes. Status : done immediately following the meeting (circulated to WG22 and SC22 under covering text as prepared and agreed by ECMA TC33 in document WG22 N113) Action 3.8 : Mr. Brockway To initiate discussion, via email among all WG22 members, on how best to proceed for ISO/IEC standardization of the PCTE IDL binding : via the CD route or by inviting fast-track of the ECMA standard. Status : done (document WG22 N86 refers, circulated by email as SC22WG22.129) Addressing Mr. Brockway's paper on the ISO/IEC standardization choice (WG22 N86), the following comments were made by members present : France in WG22 has no objection to the use of the fast-track process in this case and will probably support a fast-track submission by ECMA; Switzerland in WG22 favours the fast-track option, as likely to involve the least amount of work and time of expert resources, but seeks assurance that resources would be made available for addressing and resolving comments that might be made by member nations during a fast-track DIS ballot; the United Kingdom in WG22 is mildly in favour of the use of the fast-track process in this case, and ICL as a member of TC33 is strongly in favour. Responding to the comment from Switzerland on the need to ensure availability of resources, Mr. Dawes volunteered with thanks to take the function of Project Editor for the fast-track comment resolution process and, assisted by the ECMA Secretariat, preparation of the resulting final DIS text. In conclusion as the way forward, WG22 invited ECMA to consider submitting the IDL binding standard ECMA-230 to JTC1 using the fast-track procedure, as a DIS for a new Part of ISO/IEC 13719. Consequently ECMA TC33 decided to recommend to the ECMA General Assembly, next meeting in June 1996, that ECMA-230 be submitted to JTC1 by means of the fast-track process. After ECMA GA approval in June for this course of action, the fast-track submission would be initiated in July 1996. As an afterthought, Dr. Bird indicated that the OMG are looking into the internationalization of CORBA IDL. This was briefly discussed, and the following questions were noted : i) what impact could this internationalization of CORBA IDL have on the future envisaged JTC1 DIS ballot on CORBA IDL (following the successful SC21 CD 14750 ballot) ? ii) questions as to the (in)compatibility of OMG's internationalization of CORBA IDL with respect to the internationalization work on PCTE already accomplished by ECMA and JTC1; iii) what impact could OMG's internationalization of CORBA IDL have on the intended JTC1 fast-track of ECMA-230 ? Action 4.4 : Dr. Bird To contact Mr. Simonsen, as WG22's liaison officer to SC22/WG20 on internationalization, in regard to points (i) and (ii) above, also noting the OMG RfP as indicated on the CD 14750 ballot version (SC21 N9827). Status : new Action 4.5 : Mr. Dawes To advise the ECMA Secretariat in regard to point (iii) above, before the ECMA General Assembly meeting in June 1996. Status : new 9 Fine-grain extensions (addressed in joint session with ECMA TC33) Action 3.9 : Mr. Brockway To circulate the three FG extensions standards ECMA-227 (abstract specification), ECMA-228 (C binding) and ECMA-229 (Ada binding) to WG22 members. Status : done (in December 1995) Action 3.10 : Mr. Davis To put his one remaining outstanding FG comment on the WG22 email reflector, with a suitable deadline (at least one month) for comments. A subsequent specific proposal may then be formulated, again with a suitable deadline (six weeks for example) for WG22 members to respond. Status : carried-forward A comment on concurrency and integrity control in the FG extensions abstract specification was reviewed (WG22 N95). WG22 considered that a small, but normative, change is required. Action 4.6 : Mr. Dawes To write to the submitter of the comment (WG22 N95) on concurrency and integrity control in the FG extensions abstract specification, advising the decision taken by WG22, and then to input the result of WG22 discussion as commentary into the future SC22 PDAM ballot. Status : new 10 Status of PDAM ballots on fine-grain extensions Action 3.3 : Mr. Dawes To transform the three ECMA FG extensions standards (ECMA-227, ECMA-228 and ECMA-229, for the abstract specification, C binding, and Ada binding respectively) into documents suitable for submission to SC22 for PDAM ballots, and to provide the WG22 Secretariat with electronic and printed copies of the three documents. Status : done Action 3.4 : Mr. Brockway To then submit the three FG documents to the SC22 Secretariat with a request for PDAM ballots to be made and, in parallel to provide copies to the ITTF with a request for the ITTF to carry out a pre-edit exercise on the three documents. Status : done (however, registration ballots are being conducted first within SC22, with an end-date of 30 May 1996; the SC22 PDAM ballots will follow) The three SC22 ballot documents were noted as follows : PDAM1 to ISO/IEC 13719-1 abstract specification (WG22 N78 : SC22 N2059); PDAM1 to ISO/IEC 13719-2 C binding (WG22 N79 : SC22 N2060); PDAM1 to ISO/IEC 13719-3 Ada binding (WG22 N80 : SC22 N2061). 11 Object-oriented extensions (addressed in joint session with ECMA TC33) Action 4.7 : Mr. Brockway To circulate the latest drafts of the envisaged ECMA standards on OO extensions to WG22 members. Status : done immediately following the meeting (WG22 N90, N91, and N92, containing the abstract specification, C binding, and Ada binding respectively) More for the benefit of TC33 members, Mr. Dawes introduced some queries (document TC33/96/18) on the OO extensions draft standards, pointing out that these queriers had been produced during the process in which the three current drafts had been prepared. The queries were quickly reviewed. 12 Submission of PDAMs on object-oriented extensions (addressed in joint session with ECMA TC33) Action 3.5 : Mr. Dawes To prepare a draft plan on coordination of the timing of OO work and of approval processes in WG22, SC22, JTC1 and ECMA, for review by WG22 members. Status : done (contained within document WG22 N105) The overall plan was re-affirmed to submit three OO extensions documents (abstract specification, C binding, and Ada binding, corresponding to three future ECMA standards) to SC22 for ballots as PDAMs to ISO/IEC 13719-1, 13719-2 and 13719-3 respectively. The more specific plan prepared by Mr. Dawes (WG22 N105) was then reviewed and modified. It was considered that it might be possible to initiate concurrent registration and PDAM ballots in SC22 on the three documents in June or July 1996, and envisage publishing the three corresponding ECMA standards in December 1996. Action 4.8 : Mr. Minot, Mr. Brockway To contact the Chairman and Secretary of SC22 to pave the way (if possible according to SC22 procedures) for concurrent registration and approval ballots in SC22 on the three OO PDAMs, which can be expected to be ready for launching in June or July 1996. Status : new 13 C++ binding : future ISO/IEC 13719-4 (addressed in joint session with ECMA TC33) With sub-project JTC1.22.47.4 for the C++ binding approved by SC22 (by SC22 Annapolis Resolution 95-17), and with ECMA TC33 giving high priority to this work, the need for close coordination between WG22 and ECMA was recognized. Action 3.11 : Mr. Dawes To take all necessary initiatives to get work going on the C++ binding. Status : initiated and therefore closed (see below) Mr. Dawes referred to section 4.2 in his work programme paper (WG22 N105). Opinion differed as to whether the solution proposed is a neat way, or an untidy way, of producing a C++ binding via IDL, so a number of alternative ways forward were examined. Discussion was inconclusive, although all pres ent recognized the importance of achieving a result. Action 4.9 : Dr. Bird, Mr. Grosselin, Mr. Minot To examine whether resources can be assigned for work on a C++ binding, either taking the CORBA C++ mapping route or otherwise. Status : new A recommendation on whether to use the CD route or to invite fast-track of a future ECMA standard was considered premature. Instead it was recognized that action needs to be focussed on getting the work progressed. 14 Query facility (addressed in joint session with ECMA TC33) Dr. Bird introduced his contribution on an open systems SEE query language (WG22 N93). The contribution was reviewed with high interest, and WG22 and TC33 members gave their support to this work, resulting in the following action : Action 4.10 : Dr. Bird, Mr. Dawes To work together to bring the open systems SEE query language paper (WG22 N93) into the format of the ECMA and JTC1 standardization world, for a PCTE query facility, with a view to progression as an ECMA standard and onwards processing in JTC1. Status : new A recommendation on whether to use the CD route or to invite fast-track of a future ECMA standard was considered premature. Instead it was recognized that action needs to be focussed on getting the work progressed. 15 Further subsetting (addressed in joint session with ECMA TC33) There was no discussion this week. Contributions, for example on a minimal PCTE subset, may be made and considered in the future by WG22 and/or ECMA TC33. 16 PCTE conformance test specifications (addressed in joint session with ECMA TC33) There was no presentation this week on the European CTS5 PCTE project (WG22 N77 refers), and the two open actions were declared closed : Action 3.14 : Mr. Dawes To provide to the WG22 Secretariat a covering explanatory letter to accompany the extract draft abstract test suite from the CTS5 PCTE project, indicating the proposed way forward in the standardization world. Status : not done; declared closed Action 3.15 : Mr. Brockway When the above-mentioned covering explanatory letter becomes available, to circulate the extract draft abstract test suite and the letter to WG22 and ECMA TC33 members. Status : done for the test suite (WG22 N85); declared closed for the letter 17 Handling of defects Action 3.12 : Mr. Dawes To circulate the proposals for defect handling through the WG22 email reflector, with a request for comments and suggestions, especially in regard to making the process as automatic as feasible. Status : done (WG22 N84 and WG22 N62, as discussed below) Mr. Dawes introduced his proposal for defect handling in SC22/WG22 (document WG22 N84 dated 6 February 1996, circulated by email as SC22WG22.124, and virtually identical to the earlier WG22 N62 dated 9 November 1995). Mr. Dawes highlighted the separate proposals for handling existing and historic defect comments and newcoming defect comments, and explained how this would work. Noted in particular was annex A to the proposal (WG22 N62) and also section 14.4.6 of the JTC1 Directives. The following were among decisions taken on how the defect report forms will be completed : item 1, the defect report number, will take the form 13719/nnn, starting at 13719/001 for the first defect report and moving upwards contiguously through the integers; all defect reports will be assigned WG22 N-numbers and will be circulated to WG22 members both by email and in paper form; item 5, the date of circulation by the WG22 Secretariat, will be the email transmission date; item 6, the deadline for response from the project editor, will be computed as the date of item 5 plus two months. As to how to handle the historic and existing defect comments, the following action was agreed (also recorded in Resolution 4.4 in annex B to these minutes), with thanks to Mr. Dawes for the work involved : Action 4.11 : Mr. Dawes To prepare one single defect report to cover all EP comments pre- and post- EP-5000, leading eventually to a Technical Corrigendum to ISO/IEC 13719. This single defect report will be a simple form referencing the larger document where all comments, resolutions, and accompanying rationale for resolutions, are documented, this being a new and up-to-date version of the previous document (WG22 N61). Status : new It was agreed that the new JTC1/SC22-compliant procedure for defect handling can now apply with immediate effect, to all future defects reported, as proposed by Mr. Dawes (in WG22 N84 and WG22 N62). 18 Resolution of defects This item occupied a major portion of this week's meeting, and resulted in resolution of almost all reported defects. Discussion was based on the following input documents : comments received on ISO/IEC 13719 : comments version 3 dated 12 September 1995 (email SC22WG22.122, 123 and 125) (WG22 N61), compiled by Mr. Dawes; discussion on outstanding comments on ISO/IEC 13719 (email SC22WG22.134) (WG22 N97) from Mr. Dawes; comments on references in ISO/IEC 13719 (email SC22WG22.135) (WG22 N98) from Mr. Dawes; discussion on ISO PCTE comments (email SC22WG22.138) (WG22 N99) from Dr. Bird; discussion on outstanding comments on ISO/IEC 13719 (WG22 N101) from Dr. Bird; regarding character sets in ISO PCTE (email SC22WG22.133) (WG22 N96) from Mr. Simonsen: input from Mr. Yoshino on the multi-byte issue (email SC22WG22.137). Action 4.12 : Mr. Dawes To record the results of resolution of defects from the London meeting in a separate paper. Status : new Open actions from previous WG22 meetings were then reviewed as follows : Action 1.11 : WG22 members with actions on review of comments To pursue the actions identified for resolving comments in item 6.1 of the WG22 1st meeting minutes (WG22 N16). Status : done Action 1.12 : Mr. Yoshino, Mr. Simonsen, Dr. Bird For the way forward on comment EP-4310 on multi-byte character set, Mr. Yoshino, Mr. Simonsen and Dr. Bird agreed to pursue the remaining details to be resolved by email. Status : in progress but the action remains open (an email received from Mr. Yoshino (email SC22WG22.137) expressed his willingness to contribute on the issue and to discuss via email) Action 3.13 : WG22 members To review, comment on, and express a preference for one of the options for alternate character synonym possibilities given by Mr. Dawes (in document WG22 N29), by email through the WG22 reflector before a deadline of end-December 1995. Status : closed (no comments were received so the original proposal made by Mr. Dawes was taken as accepted) 19 Review of PCTE information on the Web (addressed in joint session with ECMA TC33) SC22 Annapolis Resolutions 95-36 and 95-38 were first recalled (in document WG22 N56 : SC22 N1970), and actions recorded at the previous WG22 meeting in Makuhari in November 1995 : Action 3.17 : Mr. Minot With regard to SC22 Annapolis Resolution 95-36, to confirm the situation with Mr. Simonsen and report back to SC22. Status : carried-forward Action 3.18 : Mr. Simonsen The Web page created with thanks by Mr. Simonsen looked good to WG22 members; it was suggested and agreed that an additional link be made to the OMG Liaison SC's Web page when it's set up. Status : carried-forward Action 3.19 : Mr. Dawes To ascertain the future of the PCTE Association's Web page and initiate action to ensure continuity. Status : underway, awaiting further news; the specific action was closed A brief review was then made of all PCTE information on various Web sites, on SC22, WG22, ECMA TC33, the PCTE Association, and on OMG Web pages. With regard to the ECMA TC33 Web page, the following action was taken by Mr. Dawes : Action 4.13 : Mr. Dawes To prepare a list of current news items concerning PCTE and ECMA TC33, to circulate via email to all TC33 members, and then to contact Mr. Lauri (Webmaster at the ECMA Secretariat) to include the agreed news items on the ECMA TC33 Web page. Status : new 20 Dates and locations of next meetings It was agreed to hold the next, 5th meeting of WG22 on 16-17 September 1996, in Hyannis, Cape Cod, near Boston, in the context of a week of co-located OMG meetings. The following schedule was provisionally agreed, noting that overlaps with relevant OMG group meetings need to be avoided and that th e schedule, and the actual days of WG22 and ECMA TC33 meetings, may need to be revised when the detailed OMG schedule becomes known : Monday 16 September (morning) : WG22 5th plenary meeting Monday 16 September (afternoon) : joint meeting of WG22 and ECMA TC33 Tuesday 17 September (morning) : ECMA TC33 38th meeting Tuesday 17 September (afternoon) : joint meeting of WG22 and ECMA TC33 Action 4.14 : Mr. Brockway To contact Ms. Bissonnette, OMG Meeting Manager, to request a meeting room for the WG22 and TC33 meetings. Status : done during the meeting (a provisional booking has been made for a meeting room on 16-17 September, to be confirmed when the final schedule becomes determined) Action 4.15 : Mr. Minot To ascertain the schedule of OMG meetings in Hyannis during the week of 16-20 September 1996, in order to avoid overlaps between key OMG group meetings and WG22 and TC33, and to propose any revision that might be necessary to the presently envisaged WG22 and TC33 meeting schedule. Status : new Action 4.16 : Mr. Brockway To obtain first preliminary and then final-form venue and logistics information from the OMG for the Hyannis meetings. Status : new Action 4.17 : Mr. Dawes, Mr. Minot, Mr. Brockway To prepare agendas and working schedules for the WG22, TC33 and joint meetings in Hyannis, and to circulate venue notices and agendas to WG22, SC22 and ECMA TC33 in due time. Status : new Looking further ahead, the date of 3-4 March 1997 was tentatively set for co-located meetings of WG22 and ECMA TC33, at a European location. Arrangements will be made in due course. 21 Back-ups for project editors This agenda item had been included to address the need for back-ups for project editors for all projects and deliverables in WG22. However, WG22 members collectively were not clear as to exactly what the back-up requirements are. The Secretary expressed his understanding that back-up volunteer persons should be identified to take over the tasks of all WG22 project editors in the event of a resignation of a current project editor. Other WG22 members thought that the back-up requirement is limited to ensuring that back-up copies of document files are adequately maintained, but that individual persons willing and able to act as back-ups need not necessarily be identified in advance. Due to this lack of common understanding, the issue was deferred until the next WG22 meeting in Hyannis in September 1996. Action 4.18 : Mr. Minot To include an agenda item for the next WG22 meeting on the need for back-ups for project editors. Status : new 22 Other business (addressed in joint session with ECMA TC33) 22.1 CEN transposition of ISO/IEC 13719 Documents on the CEN transposition of ISO/IEC 13719 were noted (WG22 N87, N88 and N89). 22.2 An open system architecture for a scaleable and extensible software engineering environment Dr. Bird provided copies of a paper on this subject for the information of WG22 and ECMA TC33 members (WG22 N94). 22.3 WG22 email reflector The situation regarding the email reflector for WG22 was reviewed. The reflector provided by Mr. Simonsen at DKUUG continues to be operational but ECMA has set up its own email reflector. WG22 members considered that, to avoid duplication of effort and costs, and to avoid confusion, there should be one and only one email reflector. The relative merits of the two reflectors, DKUUG and ECMA, were reviewed and the following action agreed upon : Action 4.19 : Mr. Dawes To contact the ECMA Secretary General Mr. van den Beld, with copy to Mr. Lauri and Mr. Simonsen, to advise that WG22 wishes to continue to use the DKUUG email reflector, and delete the ECMA reflector, in view of : i) sequence numbers already implemented in the DKUUG reflector but not in the ECMA reflector, ii) there being no in-built size limits on messages passing via the DKUUG reflector whereas the ECMA reflector would operate with a message size limit, and iii) a degree of already established familiarity in worldwide use of the DKUUG reflector. These points will also be mentioned in the TC33 Chairman's report to the ECMA Coordinating Committee, meeting on 14-15 May 1996. Status : new For TC33 members, Mr. Dawes reported that the TC33 email reflector operated until now by ICL is no longer operational. Instead, messages for TC33 members should therefore be directed to the ECMA TC33 email reflector, for which the address is : e-tc33@ecma.ch 22.4 Paragraph reference numbers in ISO/IEC publications Mr. Dawes drew attention to the outcome of the issue as to whether paragraph reference numbers can be permitted in ISO/IEC publications (WG22 N55 : SC22 N1967 and WG22 N70 : SC22 N1997 refer), an issue finally resolved with satisfaction thanks to the initiatives taken by WG22. 22.5 Publication of fast-tracked ISO/IEC DISs in their original format Mr. Dawes drew attention to the outcome of the issue as to whether a fast-tracked DIS can be published by ISO/IEC in the original format of the submitter (WG22 N74 : SC22 N2005 : JTC1 N3739 refers). Notwithstanding this situation, Mr. Brockway indicated that the ECMA Secretariat will readily under take conversions from ECMA to ISO/IEC publication styles, but added that these conversions can only be made if the documents are made available in a widely-used electronic form (Word for Windows for example rather than TROFF). In this regard, Dr. Bird volunteered with thanks to explore the possibilities for converting the PCTE C binding publication (ISO/IEC 13719-2 idem ECMA-158) from TROFF to Word as an exercise in his spare time. WG22 and TC33 members expressed their appreciation in advance, and look forward to hearin g how things go. No other business was raised. 23 Close of meeting Thanks were expressed to Mr. Dawes and BSI for hosting the meetings in London; the facilities were excellent and all participants greatly enjoyed the visit.
