As followup from recent discussion on the date-time list, below is an announcement I sent of the publicly available draft of the QUDV conceptual model to the Ontolog Community Unit of Measure working group mailing list. The announcement includes a new mailing list, [email protected], which may be used for discussion relating to this conceptual model.
This [email protected] mailing list can serve as a single point of contact with core people involved in development of this model. On a telecon yesterday, we began discussing the questions raised by Mark Linehan in his message from a few weeks ago, and we hope to start responding to these questions individually in the next couple weeks leading up to the OMG San Antonio meeting. Please note also that Nicolas Rouquette of JPL is currently scheduled to present an overview of the QUDV model during the Ontology PSIG meeting Thursday morning in San Antonio, and may be available otherwise for questions or discussion.
Thanks to Mark for catching some typos and other issues which we started to address in the most recent update of the Annex, but there are still important issues and clarifications that will benefit from our continued discussions.

A draft of a conceptual model for systems of units and quantities, currently included as part of a proposed revision of the Object Management Group (OMG) Systems Modeling Language (SysML), is linked from a wiki page at http://www.omgwiki.org/OMGSysML/.
Quoting from the QUDV wiki page,
"A working group of the SysML 1.2 Revision Task Force (RTF), working in close coordination with the OMG MARTE specification group, has completed a proposed conceptual model for Quantities, Units, Dimensions, Values (QUDV) to define systems of units and quantities for use in system models. This page is being maintained to coordinate with other groups and projects looking at similar topics. Both OMG SysML and OMG MARTE have the goal to share a common model of systems of units and quantities to support both these specifications and to align them with future international standards.
"If accepted as part of the SysML 1.2 RTF revision process, a new non-normative Annex C.5, specifying the QUDV Conceptual Model, will be added to the Version 1.2 update of the SysML specification. This draft Annex is being made available here for anyone who may find it useful or who can provide feedback"
The draft model was completed and made available on its public wiki page at the end of July 2009 after discussions and development by members of both the SysML and MARTE (Modeling and Analysis of Real Time and Embedded systems) standardization groups going back to Winter 2008. Recent key contributions have been provided by the NASA Jet Propulsion Laboratory (JPL) and the European Space Agency (ESA). A public discussion list, [email protected], has been created for discussions specifically relating to this conceptual model and its use in UML-derived modeling languages such as SysML and MARTE. The wiki page includes a variety of links including key sources such as the International Vocabulary of Metrology (VIM), with more references included in the document itself.
Minor fixes to this model may continue to be made prior to its final publication after all OMG review and adoption steps have been completed, but it is intended to serve as an interim means to define reference libraries of units and quantities for use in UML-based system models such as those of SysML and MARTE. Please see the document itself for further information.
