3	Overview An Eclipse Modeling Development Tools subcomponent at http://www.eclipse.org/modeling/mdt/?project=uml2#uml2 An EMF-based implementation of the UML™ 2.0 metamodel for the Eclipse platform Project lead is Kenn Hussey (khussey@ca.ibm.com) Users include IBM (Rational Software Architect) and Omondo (EclipseUML2)
4	Goals Provide a useable implementation of the metamodel to support the development of modeling tools Provide a common XMI schema to facilitate interchange of semantic models Provide test cases as a means of validating the specification and implementation Provide validation rules as a means of defining and enforcing levels of compliance
5	Challenges Since the specification isn’t finalized, the API is a moving target Aspects of the standard metamodel (redefinition, subsets/supersets) make the mapping to Java and XMI difficult There are a number of errors in the specification which, until fixed, make the API and XMI schema difficult to use Compliance points for UML™ 2.0 are a subject of much debate within the modeling community
6	Status – Metamodel EMF-generated API based on a collapsed version of the metamodel in which package merges and a majority of the redefinitions have been factored out Includes mechanisms to support derived union, redefines, and subsets constraints Generated using a customized Ecore “builder” and JET templates
7	Status – Interchange Default XMI schema generated using EMF Defines one namespace (http://www.eclipse.org/uml2/1.0.0/UML) for all elements, thus supporting interchange Elements identified using Universally Unique Identifiers (UUIDs) Will support import/export from/to OMG XMI for UML™ 2.0 once the specification is finalized
8	Status – Specification UML™ 2.0 Superstructure FTF has delivered final draft and report to OMG Errors discovered while using the API and/or XMI schema are now being fixed and submitted as issues to the UML™ 2.0 Superstructure and Infrastructure Revision Task Force (RTF) UML™ 2.0 Superstructure and Infrastructure RTF already has a number of open issues, available at http://www.omg.org/issues/uml2-rtf.open.html Finalization date for UML™ 2.0 Specification is TBD (soon!)
9	Status – Compliance Validation rules evaluated using EMF validator mechanism Validators implemented based on sets of OCL constraints Correspond to compliance levels
10	Milestones Maintenance release 1.0.2 to coincide with Eclipse 3.0.2 and EMF 2.0.2 Release 1.1 to coincide with Eclipse 3.1 and EMF 2.1 Release 2.0 to coincide with Eclipse 3.2 and EMF 2.x
