The Diagram Definition OMG project is another alternative for metadata interchange, which can also express the layout and graphical representation. [2] XMI is an international standard: XMI 2.4.2 ISO/IEC 19509:2014 Information technology — XML Metadata Interchange (XMI) XMI 2.0 ISO/IEC 19503:2005 Information technology — XML Metadata ...
Illustration of the Meta-Object Facility. The Meta-Object Facility (MOF) is an Object Management Group (OMG) standard for model-driven engineering.Its purpose is to provide a type system for entities in the CORBA architecture and a set of interfaces through which those types can be created and manipulated.
Compliance with the CWM specification does not guarantee tools from different vendors will integrate well, even when they are "CWM-compliant". The OMG addressed some of these issues by releasing patterns and best practices to correct these problems in a supplementary specification, CWM Metadata Interchange Patterns [4]
A model always conforms to a unique metamodel. One of the currently most active branches of Model Driven Engineering is the approach named model-driven architecture proposed by OMG. This approach is embodied in the Meta Object Facility (MOF) specification. [citation needed] Typical metamodelling specifications proposed by OMG are UML, SysML ...
The exchange format is defined by XSD (XML Schema) and XMI (XML for Metadata Interchange), a specification for transformation of OMG metamodels to XML. Pursuant to the OMG's policies, the metamodel is the result of an open process involving submissions by member organizations, following a Request for Proposal (RFP) issued in 2003. BPDM was ...
Eclipse's compliance to OMG specifications is often not strict. This is true for example for OMG's EMOF standard, which EMF approximates with its Ecore implementation. More examples may be found in the M2M project implementing the QVT standard or in the M2T project implementing the MOF2Text standard.
For example, a UML Profile abstract syntax (extending the UML 2.1 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 significant changes to some DoDAF products and adds two new viewpoints.
The OMG Structured Metrics Metamodel (SMM) [1] specification defines a standard Metrics Metamodel. It is a publicly available specification from the Object Management Group (OMG). SMM specifies a metamodel for defining, representing and exchanging both measures and measurement information related to any structured information model, such as the ...
