Richard Weston UK

(Many of the participants in WG1 were also involved as delegates in the SC5 meeting that was running concurrently with the WG1 meeting.)
2. REVIEW OF PREVIOUS MEETING MINUTES (N 412)
The minutes of the previous meeting, held in February 1998 in Boulder, USA, were accepted as written.
3. REVIEW OF AGENDA AND OBJECTIVES FOR THIS WG1 MEETING
The agenda was accepted with the following major objective noted for this meeting: to progress ISO/WD 15704 Requirements for Enterprise Reference Architectures and Methodologies to the point where it can be balloted to SC 5 as a Committee Draft.
4. REPORTS OF RELATED ACTIVITIES
a) IFAC/IFIP Task Force
The Task Force accepted the revisions to Annex A based on the N 420 draft of WD 15704.
b) CEN/TC 310/WG 1
David Shorter reported that CEN/TC 310/WG 1 held its first meeting on EMEIS (Enterprise Model Execution and Integration Services) and has scheduled the next meeting for 1998-05-26/27 to be held in Brussels. This meeting will also address the future of ENV 40 003 in view of the progress on ISO/WD 15704.
5. REPORT FROM SC 5 SECRETARY
Greg Winchester, SC 5 secretary, reported on the following issues:
·
new SC 5 password protected web site (http://www.nema.org/login.html) now on-line [WG 1 Secretary's note: links or references will be made between the SC 5 and WG 1 sites.];·
new alternative procedures for the CD and FDIS ballot stages that SCs can implement [WG 1 Secretary's note: these procedures were approved by SC 5 resolution and will be implemented immediately for WD 15704; therefore, the document will be prepared for a DIS ballot instead of a CD ballot];·
circulation of the ISO/FDIS 14258 (Concepts and rules for enterprise models) ballot with a voting deadline of 1998-07-14.6. NEAR- AND LONG-TERM STANDARDS PLAN
Members discussed a WG1 strategy that would create a family of standards that apply to interoperating processes. Thus far, WG1 has developed some high-level docuements (ISO/TR 10314-1/-2, ISO 14258) that apply to the whole domain. It was foreseen that WG 1 would, in the future, develop some standards that apply at a lower level, such as standards for model components (macros, partial models). These standards would impact users in such a way as to improve interprocess communication.
It was recalled that the ICEIMT'97 (International Conference for Enterprise Integration and Modeling Technology) had concluded that research, development, and standardization projects were needed in the following areas:
·
a unified enterprise-modeling language; for example built on CEN/ENV 12 204 (Constructs for Enterprise Modeling);·
ways to represent the human role in enterprise functions;·
a road map to identify and set priorities for enterprise-integration standards work;·
a generic-integration infrastructue, including extending the ISO/IEC 7498 Open-System Interconnect;·
requirements for process models.It was felt that a project to extend CEN/ENV 12 204 to include more modeling constructs and provide a unified modeling language would be the most useful. A group of WG 1 experts will continue discussions via e-mail regarding such a project, as well as other projects noted above.
7. REVIEW OF ISO/WD 15704 (N 420)
Members reviewed N 420 which incorporated decisions made at the last WG 1 meeting in Boulder. Members also resolved the "issues page" that accompanied N 420, as well as other comments on N 420 by Kurt Kosanke and François Vernadat.
It was agreed that ISO 15704 must accommodate different types of enterprise reference architectures and methodologies, both model-based and non model-based. Therefore consensus language was developed for clause 4 to allow the relevant requirements (e.g., specification of views for model-based ERAMs) for both types to be included. A list of definitions and abbreviations will be compiled by the editor (Ted Williams) following the editing of clause 4. It was also decided that this standard would have ISO 14258 as its sole normative reference.
A new version of WD 15704 document will be provided by Ted Williams and given to Jim Nell for posting on the WG 1 web site for member review and comment by 1998-06-15. The deadline for submission of the WD to the SC 5 Secretariat is 1998-06-30 so that a CD ballot can be issued with voting to be completed by the end of September 1998. [WG 1 Secretary's note: because of the circulation of a DIS ballot (a 5-month voting period), as explained above in item 5, it will be necessary to post the new version of the WD on the web site by 1998-06-02 for member review and comment by 1998-06-10. The SC 5 Secretary has asked the ISO Central Secretariat to arrange a DIS ballot voting deadline of 1998-11-13. This will then allow DIS country comments to be reviewed at the November WG 1 meeting in Brisbane.]
A potential copyright issue was raised regarding the desire of the IFAC/IFIP Task Force to maintain ownership of the ISO 15704 annex describing GERAM. The ISO Central Secretariat has been asked to investigate the potential of ISO 15704 bearing two copyrights: one for the main part of the standard and one for the annex.
8. SCHEDULE AND OBJECTIVES OF FUTURE MEETINGS
The next meeting will be hosted by Peter Bernus in Brisbane, Australia during the week of 1998-11-16/20. The exact dates and location are to be confirmed with Peter Bernus and relayed to WG 1 members as soon as possible. As noted in item 7, this meeting will be used to review and resolve country comments to ISO/DIS 15704. There is also the possibility that JTC 1/SC 33/WG 7 (ODP) may schedule its meeting in conjunction with WG 1.
9. OTHER BUSINESS
Members discussed the creation of a terminology facility that sets up a computer-processable way for communicating processes to mediate the respective process or enterprise version of a term or concept. This standard would be based on formal modeling concepts to insure that meaning of the terminology is congruent among the processes using the term. The agreements on meaning would be done on the fly, obviating the need to store large quantities of definitions, many of which would never be used or would not be harmonizable.
Such a project was possibly seen as more useful to an enterprise with integration needs than what SC 5/WG 3 was formed to address, i.e. an industrial automation glossary. [WG 1 Secretary's note: SC 5 formally disbanded WG 3, its working group addressing terminology issues. TC 184 did not act to form a replacement body, but instead simply requested that SC working groups examine each standard they have developed for terminology consistency.]
10. ADJOURNMENT
The convener adjourned the meeting at 1500 on 1998-05-13.
