The OMG Structured Metrics Metamodel (SMM) specification defines a standard Software Metrics Metamodel. It is a publicly available specification from the Object Management Group (OMG). An SMM model describes how metrics can be extracted from a model. It also allows for metric reporting. It is developed by the Architecture Driven Modernization Task Force. The SMM uses OMG's Meta-Object Facility (MOF) to define an XMI interchange format between metric extraction tools. It can be used to extract metrics on any MOF element even though in the specification, software artifacts are represented using the Knowledge Discovery Metamodel. == Key Concepts == The SMM defines the following key concepts: * Measure: A method of assigning numerical or symbolic values to entities to characterize an attribute of these entities. * Scope: The scope of a measure represents the domain of entities on which the measure can be applied. Minimally, a scope defines the class of measurands. * Operation: Defines a computation that needs to be executed. * Measurement: A numerical or a symbolic value assigned to an entity by a measure. * Measurand: An entity quantified by a measurement. * Observation: Measurements applied to a set of measurands. * ObservationScope: The domain of all entities on which to apply measurement for a given Observation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Software Metrics Metamodel」の詳細全文を読む スポンサード リンク
