UPDM

= UML Profile for DoDAF/MODAF =

The UML Profile for DoDAF/MODAF (UPDM): UPDM is an Object Management Group (OMG) intitiative to develop a modeling standard that supports both the USA Department of Defense Architecture Framework (DoDAF) and the UK Ministry of Defence Architecture Framework (MODAF). The modeling standard is called the Unified Profile for DoDAF and MODAF (UPDM). The UPDM initiative began in 2005, when the OMG issued a UPDM Request for Proposals. Although a UPDM 1.0 beta 1 specification was adopted by the OMG in 2007, and UPDM 1.0 beta 2 was submitted by an OMG Finalization Task Force in 2008, UPDM 1.0 beta 2 has not been endorsed by the US Department of Defense or the UK Ministry of Defence (MOD). Consequently, the UPDM initiative is still a work-in-progress.

The UPDM specification is expected to be architecturally aligned with the latest versions of DoDAF and MODAF. DoDAF v1.5 Volume II includes guidance for representing DoDAF architecture products using UML. MODAF v1.1 also provides similar guidance. However, the guidance is not sufficiently precise or complete to ensure consistent and interoperable interpretations and implementations. Differences in vendor implementations have resulted in interoperability issues between tools and additional training requirements for users. Also, the current DoDAF UML implementation guidance is based on a previous version of UML (UML v1.x), and doesn't address the current version (v2.1) or the SysML profile for systems engineering applications.

Modeling tool vendors are challenged to support a variety of DoDAF and MODAF adaptations, that have been created to meet the unique needs of several nationalities. For example, a UML Profile abstract syntax (extends the UML 2.0 meta-model) has been defined for MODAF to support XMI-based file exchange between tools and repositories. But interoperability with DoDAF tools will be difficult because MODAF made some minor changes to DoDAF products and adds two new viewpoints.

In addition to supporting DoDAF and MODAF requirements, UPDM is expected to be able to support other frameworks as well, such as the NATO Architecture Framework NAF. The requirements for UPDM are specified in an OMG RFP. [ [http://www.omg.org/docs/dtc/05-09-12.pdf OMG document dtc/05-09-12] ]

OMG Adoption Process and DoD/MOD Endorsement

Competing proposals were submitted to the OMG to satisfy the UPDM RFP.cite web|title=Team Alpha Overview: OMG document syseng/06-09-04|url=http://www.omg.org/cgi-bin/doc?syseng/2006-09-04] cite web|title=Team One Overview: OMG document syseng/06-09-05|url=http://www.omg.org/cgi-bin/doc?syseng/2006-09-05] , resulting in Unified Proposal in March 2007.cite web|title=Unified Proposal|url=http://syseng.omg.org/UPDM.htm] The Unified Proposal included support for SysML as well as UML.

The OMG adoption process for UPDM began in 2007, when the OMG organized a Finalization Task Force (FTF) to finalize the Unified Proposal specification (a.k.a. UPDM 1.0 beta 1) so that it can be made into a publicly available specification. The UPDM FTF submitted UPDM 1.0 beta 2 to the OMG in March 2008.

The UPDM FTF's March finalization report was not endorsed by DoD and MOD and consequently was not accepted by OMG because it was tied to an obsolete version of the DoDAF (DoDAF 1.0) and did not adequately meet DODAF 1.5 or MODAF 1.5 requirements. Prior to this, DoD requested an independent assessment of the finalization report by an FFRDC, which concluded that UPDM 1.0 beta 2 was unacceptable in terms of quality and meeting requirements.
