Product Lifecycle Management Services V1.0 RFP
mantis/2002-10-01

Click Here for schedule and details.

Status: Issued in Washington DC, November 2002. LOI's and Voting List are closed, two initial submissions were received and reviewed in Paris. (… see alsoMDA in Manufacturing)

Februrary 2004, Anaheim Meeting

June 2003, Paris Meeting

Uwe Kaufmann, Fraunhofer IPK, presented on behalf of PROSTEP the DaimlerChrysler submission in response to the Product Lifecycle Management Services V1.0 RFP. Background for this submission is the German PDTnet project (see www.pdtnet.org ) and the desire of the ManTIS DTF to retain the work being carried out for the former PDM Enablers V2.0 Specification and to reuse parts of the PDM Enablers under the new MDA framework of OMG.

The advantage if the PDTnet approach for "Web-Enabling" STEP PDM Schema over other approaches is that it defines a clever sub-set of the PDM Schema that is much less complex and therefore is better suited for definition of interfaces to PDM Systems. At the same time this approach also makes it easy to align the interfaces with the previously defined PDM Enablers specification. This qualifies the PDTnet Schema to become a basis for the definition of the PLM Services PIM, covering PDTnet XML Schema as well as PDME CORBA as a PSM to the PLM Services PIM.

In the presentation it was shown how the issued specification meets the RFP requirements. So far in the initial submission the following task has begun or has been completed:

For the revised submission the consideration of the full STEP PDM schema and the corresponding PIM Equivalence model has to be completed. Discussion:

21 October 2002, ManTIS Special Session

A special session of the ManTIS task force was held by teleconference on 21-October-2002. In this session the Product Lifecycle Management Services V1.0 RFP coming out of the Helsinki meeting was recommended for issuance. The TF requested the Architecture Board to hold an eMail vote to approve the RFP. The minutes can be found at mantis/2002-10-02

20 October 2002, Helsinki

The Product Lifecycle Management Services V1.0 RFP passed was recommended for issuance by the MfgDTF. The RFP ran aground in the Architecture Board, requiring three revisions. Needless to say, the AB did not approve the submission. However, several AB members assisted the task force in editing the RFP for consideration in a subsequent session. Since the funding of a number of members depended on issuance, a special session of ManTIS (its first session) was planned.

PDM Enablers V1.4 Revision Task Force (RTF)

Staus: The PDME V1.4 RTF Report was approved by the Architecture Board in Danvers, July 2001. and has successfully completed the eMail Ballot period of the Domain Technology Committee. However, no vendor committed to the Business Committee of the Board of Directors to implement the standard. All current implementation plans are focused on V1.3 of the standard. This was not a surprise since the PDME V2.0 Standard was anticipated. The V1.4 implementation plans may change now that PDME V2.0 work has ceased.

Overview: The PDM Enablers V1.4 RTF was charted during the Oslo Meeting in June 2000, with Voter Registration Closure on 16 June 2000; a Public Comment Deadline of 18 September 2000 and an RTF Revision Deadline of 18 December 2000. At the Orlando meeting, The Public comment deadline and the RTF Report Deadline were moved to 12 January 2001 and 5 March 2001, respectively. In the Paris meeting, April 2001, the Report Deadline was moved to the business day following the Danvers meeting, 16 July 2001. The PDME V1.4 RTF Report was approved by the Architecture Board in Danvers, July 2001.

The Current RTF Schedule is:

Standards Harmonization: OMG PDM Enablers & ISO-10303 (STEP) PDM Schema

Representatives of the STEP (ISO 103030) and OMG communities are working to keep their respective Product Data Management Specification sychronized, and to provide guidance to industry as to why the two standards exist and how they can be used separately or together, depending on the business scenario being addressed. It was decided to publish three white papers, an overview and guidance for technical managers, a guide for programmers, and a high level (~3-page) overview for publication.

The first paper has already been published (October 1999) as:
     "STEP and OMG Product Data Management Specifications: A Guide for Decision Makers"

Work has begun on the second paper, "STEP and OMG Product Data Management Specifications: A Guide for Programmers"

Co-Editors of the paper are
     Lutz Lämmer of ProSTEP and
     Larry Johnson of MSC.Software.

Exerpt from Summary & Findings of the Proceedings of the STEP/OMG London Workshop, May 2000.

"Presentations were made of graphical approaches to mapping, both at high RM/ODP View mapping level and at more detailed instance mapping levels. The participants felt that these graphical techniques made the mapping more accessible, and since it addressed the mapping at different levels of abstraction, more conceptually complete. Since much of this graphical mapping was completed, it was decided to refine and tighten the conventions used in their generation and include them in the next draft of the next whitepaper, "STEP and OMG Product Data Management Specifications: A Guide for Programmers".

"An aggressive date was set to get the next draft of all material that is currently complete. The skeleton of the whole paper (including incomplete items) as established in this workshop will be represented in this early draft. The schedule is as follows.

Work has also been undertaken by the Joint PDM Enablers V2.0 Submission Team (JPDM) to re-align the PdmConfigurationManagement module with STEP AP214 FDIS (Final Draft International Standard. The original specification was based primarily on CD1 and CD2 (Committee Drafts 1 & 2)


Testing PDM Enablers

PDM Enablers Implementers' Forum

In Orlando (December 2000) the Task Force chartered the Testability Working Group. Among the first activities is a Workshop to Establish a PDME Implementers' Forum for collaboration in conformance testing.

Burlingame Report on Testability

David Flater of NIST delivered a presentation on testability of specifications in Burlingame "Improving Testability of ManTIS Standards" (OMG Document mfg/2000-09-13). Based on the interest in the presentation, the ManTIS plans to charter a Testability Working Group in the Orlando December 2000 meeting to help guide submission teams responding to ManTIS RFPs and Revision Task Forces in defining interface specifications that can be used as a basis for testing compliance of implementations to the specification.

Because of the general nature of the interest, the "Testability Thread" has been moved to the Testability Working Group pages.


Previous Activities


Defunct PDM Enablers V2.0 RFP (Issued RFP)

The RFP was issued by the Domain Technology Committee at the Mesa AZ Meeting, January 2000. This RFP was caught in the squeeze between the CORBA-centric and MDA-centric approaches in the OMG. Submitters lost interest in a CORBA only specification at about the time the work was completed (the final submission was made in time for the deadline). Other factors in the waning interest was the consolidation of several of the submitters into a single company. The final submission of the team was therefore voted down at the Orlando Meeting, June 2002. The work of the submission team will be carried forward in subsequent PDM RFP's (perhaps in the role of a reference model).

Objective of this RFP

The OMG PDM Enablers specification was adopted in April 1998. It establishes a framework for interfaces to PDM services, and a base object model. It exposes most PDM-supported objects in detail and provides "fine-grained" operations to manipulate those objects and their relationships. This RFP solicits proposals to extend the adopted PDM Enablers to provide support for the following objectives:

An important requirement for this RFP is compatibility with the existing enablers. These services must be a natural and incremental extension of PDM Enablers capability rather than a different approach.

PDM Revision Task Force V1.1 (RTF)

A Revision Task Force (RTF) was chartered to address editorial and minor technical changes (which would impede implementation) to the PDM specification. The RTF disbanded on 31 March 1999, after producing its final report which can be found in OMG Document dtc/99-02-01

The RTF's final report was issued for Vote in the Philadelphia Meeting on 23-26 March 1999. The OMG PDM Enablers Specification V1.1 based on the report, passed the DTC Technology Adoption Vote, and was approved by the Business Committee & Board of Directors during the San Jose Meeting, August 1999.

Product Data Management Enablers Standard (PDM)

Currently Adopted and Available OMG Technology in PDM.

In August, 1996, the ManTIS issued a Request for Proposal (RFP) which sought to establish standard interfaces for the services provided by Product Data Management (PDM) systems. These interfaces, made available through ORBs, will provide the standards needed to support a distributed product data management environment as well as providing standard interfaces to differing PDM systems.

The RFP solicited proposals for the following Enablers:

Six initial responses, representing the efforts of 11 companies, were received in April, 1997. After review, the original submitters decided to collaborate on a joint submission, called JPDM for Joint PDM, which was submitted to the OMG on January 16, 1998. The submission document may be found at mfg/98-01-01.

The joint submission was evaluated by the task force at its February, 1998 meeting (see report) and recommended for adoption, along with its errata.  A "convenience document", which reflects inclusion of the errata into the revised submission, is available as mfg/98-02-02. The OMG Architecture Board also recommended adoption. Subsequently the joint submission successfully passed electronic ballot at the Domain Technical Committee level. The submission will face its final vote by the OMG Board in its July 1998 meeting.


Standards Harmonization: OMG PDM Enablers & ISO-10303 (STEP) PDM Schema

STEP and OMG Product Data Management Specifications: A Guide for Decision Makers

The whitepaper "STEP and OMG Product Data Management Specifications: A Guide for Decision Makers" is now issued and available. This paper was recommended for issuance by the ManTIS in the Cambridge Meeting, on 16 Nov 1999, and subsequently issued by the Domain Technical Committee of the OMG on 19 Nov 1999. During the week of 9 Nov 1999, the paper was endorsed by the ISO STEP community through unanimous resolution.

This paper represents the culmination of 10 months of international collaboration. The following companies and organizations contributed as representatives of themselves and variously of OMG, ISO TC184 SC4, PDES Inc., ProSTEP, and NCMS.

The paper best explains itself. The following is the "Executive Summary" and "Introduction" from the document:

Executive Summary:

"Product Data Management (PDM) is an increasingly important technology for engineering and manufacturing enterprises. The information technology that supports Product Data Management requires standards in order to allow interoperability between systems and the sharing of product information between organizations. Two important sources of standards in this area are the Object Management Group (OMG) and the International Organization for Standardization (ISO) STEP community (officially ISO TC184/SC4 Industrial Data). This document will show how these two standards work together to support engineering and manufacturing processes in today's business environment.

"OMG and ISO are organizations that develop and promote standards. The OMG and STEP communities work independently to develop standards for different purposes and that differ in scope, abstraction level, and operational characteristics. The OMG standard defines a standard interface to the services of a PDM system in a distributed, object oriented environment. The STEP standard defines a standard representation of product data including data that is typically managed by a PDM system.

"However, the OMG and STEP communities have worked together to harmonize their respective standards in the area of Product Data Management Standards so that the standards complement each other rather than conflict or overlap. A formal liaison relationship has been established between OMG and ISO TC184/SC4 to facilitate this harmonization. This document provides a technical comparison of the OMG and STEP standards; a high level architectural approach for the use of these complementary standards to satisfy business requirements in real world scenarios; and guidelines for how and when to use these standards."

Introduction:

"The focus of this document is to provide information on the comparison and harmonization of the Product Data Management Standards developed and promoted by both the OMG and STEP Standards Communities. The OMG and STEP communities have come together to specify the complementary aspects of these two standards defined herein. This document outlines scenarios and defines the high level architectural approach for the use of these complementary standards and provides decision criteria for how and when to use these standards to satisfy business requirements.

"STEP and the PDM enablers are different in purpose, scope, abstraction level, and operational characteristics. Despite these differences, and because of these differences, each provides an essential piece in the process of defining and managing product data."

Intended Audience:

"This document was written for managers, designers and implementers of applications, which will employ OMG and STEP Standards to share and exchange PDM information."

Workshops:

The paper is the product of an ongoing series of telephone conferences, network meetings, and two workshops. The workshops are described below

Report of Second Workshop

On March 17-18, 1999 a second joint workshop was held between the developers of the OMG PDM Enablers and the STEP PDM Schema. The focus of the workshop was to continue work on the two major deliverables identified at the first joint workshop held in December 1999.

The group reconfirmed the major conclusions of the first workshop, which were:
   1 - all parties agreed that the two organizations
         were indeed producing complementary standards;
   2 - the developers of both standards would continue to coordinate efforts
         in producing a joint set of deliverables addressing the use of and
         relationship between the standards;
   3 - coordination in other areas of development should continue.

This second workshop resulted in an initial working draft of a white paper, directed at managers and system integrators, outlining scenarios and a high level architectural approach for the use of these complementary standards. The workshop also continued work on the technical mapping between the two standards, directed at implementors, completing a high level semantic comparison of the two standards and agreeing to an approach for documenting a detailed mapping between the two standards. The plan is to distribute a public draft of the scenarios and architectural approach white paper in May 1999 with
the technical mapping document to follow shortly thereafter.

For more information about this workshop and future activities of the work group please monitor the scpdm.aticorp.org web site or contact one of the participants.

Report of First Workshop

On December 9-11, 1998 a joint workshop was held between the developers of the OMG PDM Enablers and the ISO 10303 (STEP) PDM Schema. The focus of the workshop was the comparison and harmonization of Product Data Management standards being promulgated by both the OMG-ManTIS and ISO-STEP communities. The major conclusions of the workshop were:

  1. All parties agreed that the two organizations were indeed producing complementary standards;
  2. The developers of both standards would continue to coordinate efforts in producing a joint set of deliverables addressing the use of and relationship between the standards;
  3. Coordination in other areas of development should continue and the two organizations will develop a Memorandum of Understanding to formalize the relationship.

The work group identified two major deliverables to the PDM community in support of the goals of the workshop. The first deliverable will be a white paper outlining scenarios and a high level architectural approach for the use of these complementary standards to help users, managers and system integrators in making decisions about how and when to use these standards to satisfy their business requirements. The second deliverable will be a formal mapping between the two standards to help implementors understand the relationship between the technical capabilities of the two standards. The plan is to complete these papers during the first half of 1999.


International PDM Enablers Implementation Workshop, February 1998, Costa Mesa CA

A number of companies and consortia interested in implementing pilots employing the PDM Enabler specification held a  PDM Enablers Implementation Workshop, February 25-26, 1998, in Costa Mesa CA. This workshop was formed to bring vendors together with  those organizations interested in using standard interfaces to their PDM systems.

Workshop Objectives:

concerning the application of the OMG PDM Enablers to real-world business environments, both in pilot and production systems.

Among the issues discussed were:

The proceedings of this workshop are available as OMG document  mfg/98-06-15 .
