CC: US TAG to ISO/IEC JTC1/SC24 Date: October 4, 1994 Enclosed is a liaison statement from the Object Management Group (OMG) to ISO/IEC JTC1/SC 24. The statement has the approval of OMG President Chris Stone, Vice President and Technical Director Dr. Richard Soley, and Director of Program Management and Chairman of the Liaison Subcommittee Dr. Jon Siegel. The statement refers to OMG's disapproval of attempts by SC24 and its working groups to modify or adapt OMG specifications. We are putting such disapproval into this formal statement because JTC1 SC 24 has not ceased attempts to modify or adapt OMG specifications after being notified several times previously. OMG has established a productive, two-way, working relationship with ISO/IEC JTC1/SC 21 Open Distributed Processing (ODP) which we propose as a model for a relationship with JTC1/SC 24. We are anxious to work with members of SC 24 towards such a goal. Communications to OMG on this matter should be addressed to Dr. Jon Siegel, Chairman of the Liaison Subcommittee for OMG. Respectfully, Jon Siegel Chairman, Liaison Subcommittee and Director of Program Management Liaison Statement to ISO/IEC JTC1/SC24 from the Object Management Group October 5, 1994 The Object Management Group (OMG) has received copies of statements ISO/IEC JTC1/SC24 N 1195, Liaison Statement on Formal Description Techniques, and N 1196, Object Technology in PREMO. OMG does not approve of attempts by ISO/IEC JTC1/SC24 or any other group to modify or adapt OMG specifications outside of the OMG process. Because OMG is absolutely committed to the stability of its specifications, the Group does not allow modification of these specifications outside of its established and deliberate procedures. This policy has successfully led to the creation of a rapidly growing market already populated by a number of software products representing a large development investment. The OMG revision process is built around a committee which includes all of the original technology contributors. Their recommendations are subject to approval by 2/3 vote of the OMG Technical Committee, followed by vote of the OMG Board of Directors, ensuring the stability we require. In addition to stability, interoperability standards must be adoptable universally in order to be useful. Many groups - not just ISO/IEC JTC1/SC24 - would like to modify or extend OMG specifications. Focusing their efforts through OMG avoids otherwise certain divergence into a suite of alternative standards which would lack the commonality required to interoperate. Established OMG procedures allow diverse groups to input requirements into a single, widely-applicable specification. OMG's open membership policy and task-force based technology adoption procedure produce a forum where these groups come together to adopt specifications which take all of their needs into account. OMG offers its specifications to ISO/IEC JTC1/SC24 for adoption as ISO standard by reference only. Under these conditions OMG will accept - and in fact will welcome - requests from ISO/IEC JTC1/SC24 for modifications or extensions to OMG specifications through OMG's established process. OMG has made an identical offer to ISO/IEC JTC1/SC21 WG7 (ODP) and a productive, two-way working relationship has been established. OMG would be pleased to participate in such a relationship with JTC1/SC24 as well. OMG reminds ISO/IEC JTC1/SC24 that OMG has only granted permission for limited copying of OMG specifications without change, for purpose of committee deliberation and balloting. JTC1/SC24 has requested additional permissions from OMG but these have been denied, for the reasons stated above. This position is not going to change. OMG does not approve of attempts by JTC1/SC24 members to obtain copyright permission from individual OMG member companies outside of normal OMG process. Although any individual copyright holder can grant permission for JTC1/SC24 to copy, and even modify, an OMG specification, this would not establish a basis for cooperation between the two groups. In fact, OMG would find it almost impossible to cooperate further with JTC1/SC24 should that committee utilize OMG specifications via copyright acquired outside of a liaison relationship directly with OMG itself. --------------------------------------------------------- Steve Carson phone: +1-505-521-7399 GSC Associates Inc. fax: +1-505-521-9321 5272 Redman Road e-mail: carson@siggraph.org Las Cruces, NM 88011 USA ---------------------------------------------------------
