Subject: FW: ISO CD 11179-3 Ed3 ("Metadata Registry Metamodel") is out for ballot
I don't believe anyone in RegReg has been involved in OMG or in the ISO 11179-3 Ed3 revision. Is the discussion below a concern to RegRep? I don't think so, but wanted to check with all of you. Kathryn Breininger Boeing Library Services 425-965-0182 phone -----Original Message----- From: Ed Barkmeyer [mailto:edbark@nist.gov] Sent: Wednesday, October 03, 2007 4:07 PM To: OMG ADPTF; Business Modeling & Integration DTF; iso11179@omg.org Subject: ISO CD 11179-3 Ed3 ("Metadata Registry Metamodel") is out for ballot All, This is an alert. The new Metadata Registry Metamodel standard appears to overlap assorted OMG work with no effort at alignment. ISO 11179 Ed2 (2004) is a standard for the management of registries of "data elements": terms and codes. It is mandated for use by ISO "registration authorities" for things like language codes and country codes, and by other authorities for things like standard metropolitan sampling areas, medical diagnostic and treatment codes, labor classifications, and the like. Aside from being a useful model of the distinction between the semantic objects and the representations, the primary strength of ISO 11179:2004 is the capture of "Lifecycle and Versioning" information -- provenance, effectivity, and responsibility -- for the individual data elements. The purpose and scope of the newly revised specification, ISO 11179 Ed3, now out for ballot, is less clear. The scope has been extended to managing "terminologies" and basic modeling elements: classes, attributes, relationships, and so on, and to managing "classification systems" and "ontologies". The intent appears to be to apply the lifecycle and versioning concepts to vocabularies and modeling concepts. But in this new area, the specification does not even mention ISO 19502 (MOF), or ISO 19763 (Framework for Metamodel Interoperability), which was closely worked with OMG, even though both of these standards were progressed through the same ISO committee (JTC1/SC32). This new specification overlaps with OMG work in the area of MOF Lifecycle and Versioning, and possibly with SBVR. That is why Hajime Horiuchi (OMG Liaison to JTC1/SC32) and I are bringing this draft specification to your attention. The current committee draft of the ISO 11179 registry metamodel, Part 3 of the standard, is now out for ballot in the participating National Bodies in ISO JTC1/SC32 (Databases and Data interchange). The registry metamodel is presented in UML. The draft specification is available at http://www.jtc1sc32.org userid= jtc1sc32 password= openedi The document number is N1667T: Click on "Document Library", then on "N1651-N1700 folder", then on "32N1667T-text for CD11179-3.pdf" OMG experts are encouraged to send their comments to their National Body group that is responsible for review and ballot on this specification in their respective countries*. In addition, the Liaison Committee agreed at the Jacksonville meeting to collect any and all OMG expert comments on a new exploder: iso11179@omg.org and to formally present them to JTC1/SC32 as expert contributions to be considered when editing the specification. Like OMG Issues, these comments can address any technical aspect of the specification, including scope and conformance, and also its relationship to other national and international standards. The ballot closes on November 19. So we intend to gather up all comments received by November 13 and send them forward. OMG could take a formal position on this draft ISO standard by TC ballot at the December meeting, and we can discuss that once we have comments in hand. OMG does not VOTE on the specification; only the national body organizations do. For the OMG Liaison committee, - Ed Barkmeyer, NIST P.S. I made a brief presentation on this at the Jacksonville ADPTF meeting. The text above is a summary of that presentation. * The SC32 website does not provide either identification or contact information for the participating National Body organizations. The U.S. "TAG" is INCITS L8, which was the primary developing body. There are corresponding groups in AFNOR, BSI, DIN, JSA, NNI, etc. You can find out how to contact your national body from the Secretariat: Dr. Timothy SCHOECHLE Telephone: +1 303 443 5490 E-mail: sc32-sec@jtc1sc32.org -- Edward J.
