Covering the Period: August 2004 to May 2005
Title of Subgroup: Open
Distributed Processing (ODP)

T3 uses only the INCITS web site: INCITS T3 WEB SITE
Develop a Reference Model of Open Distributed Processing (RM-ODP) to coordinate the development of distributed processing standards. Also, develop specific and related standards for components of ODP, which includes ASN.1, OSI System Management and OSI Directory Services. T3 also serves as the US TAG for ISO SC 6. Currently, all T3 projects are international.
With great assistance from the INCITS Secretariat, T3’s Program of Work is now in reasonable form and for the most part, it is now well within the embrace of the T3 membership.
OSI Directory, ASN.1, and Open Distributed Processing (ODP) activities continue to be very strong including the approval of new work items.
Regarding the operation of the T3-based US SC 6 TAG, most
of the problems related to the large number of SC 6 activities outside of T3’s
Program of Work and worse, the T3 member expertise have been addressed through
T3 member involvement and declining on selected technical areas (with the
support of the INCITS Secretariat. The only known
Electronic mail continues to be a major success for T3 wherein nearly all aspects of the T3 program of work are being satisfied. T3 maintains its efficiency by operating through Topic Leaders. The Topic Leader’s responsibility is basically a subset of the IR’s (all T3 projects are international). However, the IR continues to have overall responsibility. This has proven to be very successful in handling and focusing the broad topic area of T3. We plan on continuing this practice indefinitely.
The T3 Chair is most indebted to the members of T3 for their efforts in compiling this report.
Note that the Formal Definition Techniques (FDTs) Project was dropped this period by T3 and the INCITS Secretariat due to lack of interest and no member participation. This also entailed T3 dropping its participation in the SC 22 TAG.
Also there were no changes for this period on the topics OSI Systems Management and OSI Routing Protocols.
Certainly our most ambitious activity over the last 4 periods has been to refine the T3 operation of the SC6 US TAG. In this last period with the help of INCITS, T3 now has a stable Program of Work for SC 6 projects relevant to T3 and supported by its members.
In ODP, The Enterprise Language Standard Rec. X.911 | ISO/IEC 15414 has been published as collaborative text. ISO/IEC 15414:2002/CD Amd 1. Amendment 1 to ODP – Enterprise Language, which was completed within WG19, is now incorporated in the April 2005 version of ISO/IEC 15414. The work of WG19 is on UML Pas ballots and the project on UML for ODP. UML 1.3 has been approved as ISO/IEC 19501-1. The UML PAS ballot, which fully aligned the ISO/IEC UML text in ISO/IEC 19501-1 with OMG UML 1.4.1 was fully completed last year. The UML standard is awaiting final publication by ISO. Major work was completed on standards for the ODP Enterprise Language and the ODP GIOP/IIOP protocol, while the UML for ODP continues in its development. Derivative standards from the ODP reference model continue.
For The Directory over the last year and a half, the
Four projects are currently under development for the next edition of The Directory. Each of these has been passed the FPDAM ballot:
· Support for paged results on the Directory System Protocol, removing the previous restriction that paging be supported only on the DSA adjacent to a DUA
· Support for the concept of friends attributes, providing for support of applications requiring semantically related, but syntactically different attributes in the Directory
· Maximizing alignment with LDAP, providing mechanisms necessary to allow interoperability among X.500 and LDAP directories
· Enhancements of public key and attribute certificates.
The results of these projects
will not be published as Amendments. Instead, the editors are incorporating the
amendments, along with approved Technical Corrigenda, into a fifth edition.
That integrated text was approved at the recent ITU-T Study Group 17 meeting in
One meeting has been held since the last report-- in
For ASN.1, work has been completed on rules for mapping from XSD to ASN.1, which was balloted and approved as ISO/IEC 8825-5 along with Amd 1 to ISO/IEC 8824-1, -2, 8825-1, -2 and -4 which support it. This permits messages described using XSD to take advantage of compact ASN.1 encoding rules such as PER.
The ASN.1 committee has also continued work on "Fast Web Services" which is expected to mature to two standards (ISO/IEC 24824-1 and ISO/IEC 24824-2). The FCD ballots on these have been completed. The FDIS ballots are expected to begin in June or July of 2005.
International meetings of the ITU-T|ISO/IEC ASN.1 standards committee were held November 24-28, 2003 with JTC1/SC6 in Jeju Island, Korea,, January 26-30, 2004 in Paris, France, March 10-19, 2004 with ITU-T SG17 in Geneva, June 21-25, 2004 in Manchester, England, September 13-17, 2004 in Nice, France, November 8-12, 2004 with JTC1/SC6 in Orlando, and March 30-April 8, 2005 with ITU-T SG17 in Moscow, to progress XML schema mapping to ASN.1, work on "Fast Web Services", ECN support for the open type, and registration of UUIDs. The XML schema mapping work was approved by FDIS ballot in May 2004.
Note that due to the mature status of most of the T3 projects, it is rare that T3 has the opportunity to publish new base standards. Rather, most work is in refinements and enhancements to base standards and their derivatives.
This former JTC1/SC33 project and other ODP-related projects have been in SC7 and managed by the US SC7 TAG since the 1999 period. Through a ratified agreement written by INCITS, T3 is permitted to carry out the ODP TAG activities in behalf of the US SC7 TAG. This single project now covers all SC7 ODP activities. All the SC07 ODP projects are now within WG19.
The Enterprise Language Standard Rec. X.911 | ISO/IEC 15414 has been published as collaborative text. ISO/IEC 15414:2002/CD Amd 1. Amendment 1 to ODP – Enterprise Language, which was completed within WG19, is now incorporated in the April 2005 version of ISO/IEC 15414.
The work of WG19 is on UML Pas ballots and the project on UML for ODP. UML 1.3 has been approved as ISO/IEC 19501-1.
The UML PAS ballot, which fully aligned the ISO/IEC UML text in ISO/IEC 19501-1 with OMG UML 1.4.1 was fully completed last year. The UML standard is awaiting final publication by ISO.
WG19 has been working CD ballot resolution for the “Use of UML for ODP Viewpoint Language Specifications” collaborative project with ITU-T SG17 (ISO/IEC 19793 | ITU‑T Recommendation X.906).
For the future, T3 will focus on:
· The progression of the UML for ODP work to Final Committee Draft and FDIS Status
·
Any future revision work required for the
OMG,
as a PAS submitter to JTC1, is planning to submit several OMG ODP
specifications for future PAS ballot. T3 will prepare the
The OSI Directory projects consist of defect resolution of two mostly recently published editions of the directory specifications (1998 and 2002) and of four amendments being developed for incorporation into the fifth edition of the Directory specifications. The 1998 edition of Parts 1, 2, 3, 4, 5, 6, 7, and 8 are ISO/IEC Third Editions. The 1998 edition of Part 9 is ISO/IEC Second Edition. The 1998 edition of part 10 is ISO/IEC First Edition. The 2002 edition of Parts 1 through 7 is the Fourth Edition. The 2001 edition of Part 8 is ISO/IEC Fourth Edition. The 2002 edition of Part 9 is the Third Edition. The 2002 edition of Part 10 is the Second Edition. However, the common practice is to refer to the entire set of parts as an edition. Therefore the set of all parts published in 1998 are referred to as the third edition and the set of all parts published in 2002 are referred to as the fourth edition.
Four projects are currently under development for the next edition. Each of these has been passed the FPDAM ballot. The projects are as follows:
· Support for paged results on the Directory System Protocol, removing the previous restriction that paging be supported only on the DSA adjacent to a DUA
· Support for the concept of friends attributes, providing for support of applications requiring semantically related, but syntactically different attributes in the Directory
· Maximizing alignment with LDAP, providing mechanisms necessary to allow interoperability among X.500 and LDAP directories

The Collaborative Directory group maintained liaison with the Internet Engineering Task Force on both Lightweight Directory Access Protocol (LDAP) and Public Key Infrastructure Extension (PKIX) issues.
The ASN.1 committee completed work on rules for mapping from XSD to ASN.1, which was balloted and approved as ISO/IEC 8825-5 along with Amd 1 to ISO/IEC 8824-1, -2, 8825-1, -2 and -4 which support it.

The XML schema mapping work was approved by FDIS ballot in May 2004.
Paul Thorpe, a T3 member and the editor of the ASN.1 standards continues to attend the meetings and actively participate in the ongoing ASN.1 standards work.
The T3 ASN.1 group
plans to take the work in progress on "Fast Web Services" to
completion and progress work on full support for the ISO 8601 time types in
ASN.1. The next two international
meetings are scheduled for August 29-September 2, 2005 with JTC1/SC6 in
Saint-Paul de Vence,
There were no changes in this topic for this period. For convenience, the 2002 report is restated.
All Systems Management projects are now assigned to ITU and have been grouped under one project for convenience. Also included are the former projects of Open Distributed Management Architecture (ODMA) and Common Management Information Service (CMIS).
It is T3 understands that it has no formal responsibility to this activity. Due to our informal relationship with ITU Study Group members, T3 can at its discretion volunteer contributions to ITU work.
Standards in this project are managed by ITU-T, which fast tracks amendments and corrigenda at the JTC1 level as class A liaison for existing published Joint standards. New Standards for this project are ITU-T only, however. T3 is willing to provide US recommendations on these Fast Track amendments on corrigenda on these existing published Joint OSI management standards.
There was a ballot for an amendment to ISO/IEC 10164-2 on Lifecycle state (progressed as fast track from ITU-T). T3 recommended a yes vote on this fast track amendment.
There were no changes in this topic for this period. For convenience, the 2002 report is restated.
During this reporting period, T3 has recommended the withdrawal of test standards of this project. There has been no other T3 activity on this project. If no further interest develops in the next reporting period, T3 will likely recommend its removal from the T3 program of work.
The following is included from last year’s report to assist in recalling the background of this project:
This SC 6-related project is included for continuity and for information only. T3 has lost the members that supported these projects and currently has no technical expertise among the remaining members.
06.41 End System to Intermediate Systems
Routing Exchange Protocol
All work is believed complete. The draft amendments 2 and 3 have not yet been published, and do not appear on the SC6 program of work. None of these amendments have yet been published by ISO and the amendments do not appear on the SC6 program of work. The reason for lack of progress of the amendments 2 and 3 is unknown.
06.41.04 Intermediate
System-Intermediate system intra-domain routing Protocol (ISO 10589)
The preliminary draft was published September 2000. Updated versions were published to the IETF on 07-04-01. The final version which was delivered back to the ISO was published on 08-22-01.
A Draft of ISO
10589 v2 was developed and has undergone an email editing meeting, ISO review,
and IETF review. The FDIS vote was held
on the proposed draft of ISO 10589. The
proposed draft of ISO 10589 was voted down with French and US comments. The changes required by the
At this point, it is expected that work related to this protocol is at an end. All future work is expected to take place in the IETF, with regards to Internet Protocol extensions.
Please note that all T3 projects are international.
T3’s continued and most significant challenge has been organizing and adapting to its new demands incurred by becoming the US SC 6 TAG. T3 also recognizes that an equal amount, if not more, of such demands has also been incurred by the INCITS Secretariat. Although during this period the problem has lessened, a continued challenge, realized more by the INCITS Secretariat, has been determining the exact program of work as it applies to SC 6 US TAG. This has taken a great deal of effort to baseline.
T3 continues its process of permanently abstaining on certain SC 6. As T3 becomes more aware of the complete SC 6 program, T3 will attempt to find new members that are interested other areas of SC 6. (Note T3 has been using the general guideline of having at least 3 interested members per project to form a reasonable consensus.)
The challenges for the next period are expected to be mostly those of the last three periods.
Of special note is that T3 is increasingly becoming a forum for US companies and agencies to protect their investment in previous standards work. This is due to the maturity of most of the T3 standards. What little new work exists in T3 is mostly refinements and enhancements of essentially long-term stable standards.
