2 Review of Agenda and Meeting Objectives
The agenda was approved as distributed with minor changes in the order that agenda items would be addressed.

3 Review of Previous Meeting Minutes
The minutes (N421) were approved as written.

a) IFAC/IFIP Task Force
Peter Bernus, Task Force Chairman, noted that the Task Force meeting in conjunction with this WG 1 meeting will concentrate on common interests regarding lifecycle and the development of consistent approaches to it.

b) ISO/IEC JTC1/SC7
Terry Rout, JTC1 SC7's new liaison to SC5, reported that JTC1 SC7 is writing standards addressing software product evaluation. These standards, being written by SC7 WG7, rely on evaluation modules, some of which could be manufacturing related. SC7 is also addressing functions size measurement (like function points, but generalized) and needed schemas. This involved the identification of applications domains and what characterizes, for example, a real-time domain, a secure domain, or manufacturing domain. The Convenor of SC7 WG7 is Professor Azuma; ACTION ITEM: Terry Rout to provide Professor Azuma's email address.

c) ISO/IEC JTC 1/SC 33
Terry Rout reported that JTC1 SC21 has been disbanded. SC33 has been assigned the responsibility for ODP work that was previously done by SC21.

d) CEN/TC 310/WG 1
David Shorter said that WG 1 is proceeding with drafting a prENV for EMEIS. Jean-Jacques Michel added that France will likely propose that TC310's M-IT-04 document be put on the ISO TC184 Web page with appropriate hyperlinks added to ease navigation and maintenance. There was question, however, regarding where the resources would come from to do this maintenance work.

David Shorter also reported that an extension of ENV 12 204 would be possible future work for TC310 WG1. David was asked if this work could be done jointly (i.e. in parallel as provided by the Vienna Agreement between ISO and CEN) with SC5 WG1. David Shorter mentioned that TC310 would likely develop the 12 204 extension, keeping SC5 WG1 abreast of the effort, and then fast-track the document in SC5 (i.e. introduce it for DIS voting).

e) SC5 Study Group on Manufacturing Software Capabilities Profiling
Greg Winchester reported that the study group held a meeting in October 1998, but that attendance was slim. This called into question whether the support and resources would be available to propose and undertake a new SC5 project in the area. Thus, the Study Group had agreed to limit its effort to producing a report to SC5 that would include recommendations for standardization projects, if any. A January 1999 Study Group meeting will be held to finalize the report if attendance is adequate.

f) JOP and MES
Yoshiro Fukuda provided a presentation on JOP, the Japan Factory Automation Open Systems Promotion Group. The JOP activity, involves participation from 40 industrial companies in Japan and is based on the manufacturing execution system work by MESA International. JOP is evaluating the MES concept for a framework of a machining system application. CORBA and JAVA is being used to define the communications from the device level to the enterprise-resource-planning level. Initial demonstrations of the framework, and associated middleware, will begin in April 1999.

g) SC4
Jean-Jacques Michel noted that ISO TC 184 SC4 WG10 is now investigating a life-cycle architecture, and is working on a binding between EXPRESS and UML. SC4 is working on two new standards: ISO 15926 that will deal with the oil and gas industry, and a new AP for operation and maintenance. These contain life-cycle architectures similar to those covered by ISO 15704. ACTION ITEMS: Jim Nell to discuss coordination of lifecycle work with the SC 4 Chairman. WG1 asks that Jim Nell attend a January 1999 workshop addressing UML, XML, and EXPRESS relationships.

Jean-Jacques Michel reported that he had presented MANDATE in response to a RFP in field of manufacturing by the Object Management Group. OMG will probably use the MANDATE model for resources. MANDATE (SC4 WG8) is working in four areas: resource management, time model, flow management data, and external exchange. MANDATE is using the Basic Semantic Register (BSR). The BSR is being used for the exchange work instead of developing its own model.

h) ISA SP95
Ted Williams reported that ISA (the Instrument Society of Measurement and Control) is developing a model of the interfaces between the ERP and MES domains. This work is being based on the Purdue enterprise-reference-architecture.

i) SC 5/WG 5
WG 5, through strong participation by the Open DeviceNet Vendors Association, is currently working on a framework for CAN (ISO 11898)-based application profiles for the moment. Japan has agreed to develop a more general framework that will include non-CAN profiles.

a) ISO 14258 Technical Corrigendum
Greg Winchester noted that ISO 14258 was published with only a fraction of the necessary corrections made. WG1 members agreed that the current errors in 14258 cause ambiguities in the interpretation of the document and would result in incorrect application of the standard. Thus, it was felt the publication of a technical corrigendum is appropriate. ACTION ITEM: SC5 Secretariat to collaborate with Jean-Jacques Michel to produce a technical corrigendum based on a list of errors developed by David Shorter.

b) ISO/DIS 15704 Ballot
Greg Winchester reported that he had received 8 responses (7 from P members), with comments only from the UK and USA. Since comments were submitted, the new operating procedures being used by SC5 require that 15704 will have to undergo a FDIS ballot.

c) 15704 Annex A Copyright
Greg Winchester reported that ISO Central Secretariat sees no problem with having separate copyrights: one covering the requirements, the other covering Annex A (GERAM example).

d) SC 5 Website
The SC 5 Website has been upgraded and is now at the following URL:

http://forums.nema.org:8080/~iso_tc184_sc5

Since the previous postings were in a proprietary format, it was not possible to transfer it to the new SQL-based site. Thus, the SC 5 Secretariat will gradually rebuild the content, establishing hyperlinks with Web sites of the SC 5/WGs.

e) SC 5 Plenary Meeting
Greg Winchester noted that, based on the 28-29 April 1999 date for the SC5 plenary meeting, the agenda for this meeting will be issued on 31 December 1998, and that the SC5 WG1 Convenor's report must be submitted by 1999-February-08.

Jim Nell noted that, as requested by SC 5, he must make a statement in his Convenor's report regarding the impact of the Year 2000 problem on WG1 standards. This statement will identify no such impact.

6 Review of ISO/DIS 15704 Country Comments
Each comment submitted by the UK and USA was discussed and resolved. One UK comment unearthed problems associated with Annex A figures employing colors. ACTION ITEM: Peter Bernus to revise Figure A.10 and provide black-and-white versions of Annex A figures.

It was agreed that country comments submitted before the 1998-December-23 ballot deadline would be handled by the WG 1 Convenor, WG 1 Secretary, and 15704 Editor. Treatment of the comments would then appear as a front page to the WG1 Web site version of the DIS.

7 Road-Map Discussion
WG 1 members discussed at length a strategy to create a family of standards that apply to interoperating of enterprise processes. The following areas were identified as topics for a road map of this standardization strategy:

1 Improved Enterprise Modelling concepts
• Simpler application standards
• [Process] model reuse
• Model quality {assurance} requirements
• Prescriptive extension to ISO 14258

2 Improved manufacturing semantics
• On-line terminology facility
• Ontology (cf. PSL translation, SUMM)

3 Enterprise Engineering
• Use ISO 9000 paradigm in Enterprise Engineering process
• Define issues and metrics in enterprise engineering [e.g. what risks]
• Add "meat" to GERAM skeleton
• Populate extensions to ISO 15704 [with methodological views]
• Define modules and interfaces between them in enterprise engineering

4 Awareness/dissemination of existing standards
• Instructional material to explain (?) architectures and methodologies (or rather show how they can be used. May be an IFAC/IFIP issue)
• Populate with existing standards (cf. 10314)

5 Reference Models for Enterprise Engineering (Title?)
Partial [Reference] models [for]--specialisations [for kinds of industry, for particular purposes].
• AP203 Parts Road Map
• AP221 Process Plant
• AP .?. Oil and Gas
• AP214
• JOP's MES (release depends on IPR discussions with IBM Japan)
• ISA's work on the Purdue Reference Model

These topics were then distilled into the following list of parts comprising a possible standard for producing high-quality enterprise solutions:

Guidelines and philosophy of use Jim Nell

[For a product of enterprise engineering,] Quality assurance requirements Later
life cycle of any enterprise entity development

Management of enterprise models (configuration management, David Shorter

traceability)

Process model for enterprise engineering (extension of ISO 15704) Peter Bernus

Guidelines for development and application of partial models J-J Michel,
Y. Fukuda

Model storage, representation, exchange, translation, and unification Peter Bernus

ACTION ITEMS: Champions identified above to identify industry contacts and research the components of a new work item proposal. SC 5 Secretariat to furnish each champion with an electronic template of the ISO New Work Item Proposal form.

8 Schedule of Future WG 1 Meetings
DATE: 26-27 April 1999 (Monday-Tuesday)
LOCATION: London, Ontario, Canada (in conjunction with SC 5 plenary)

This meeting will be used to discuss new-work-item proposals based on the WG 1 road map.

9 Other Business
