Description: The UN/CEFACT UCM Classification Scheme Profile specifies UML Profile classifiers for restricting UML to suit UN/CEFACT UCM classification scheme modeling within the Semantic Modeling Dimension of the UCM Reference Architecture. This Profile defines a set of classifiers which can be used for defining a model for organizing information, defining classification values and relationships, or both. It imposes no specific modeling approach and facilitates multiple mechanisms to be used, such as relational mechanisms, tree-based mechanisms, set-based mechanism, etc. This profile defines lightweight techniques for extending OMGs Meta Object Facility (MOF) layer 2 UML. XSD: Description: Classifiers stereotyped as ClassificationScheme provide the foundational UML extension for identifying a specific UCM classification scheme approach. XSD: Description: The id property provides a set of fields supporting a flexable identity mechanism. XSD: Description: The name property provides a simple readable name. Description: The majorVersion property provides versioning capability where increments of integers are not guaranteed to be backwards compatible with earlier major versions. Description: The minorVersion property provides versioning capability where increments of integers are within majorVersions, and are guaranteed to be backwards compatible with earlier minor versions. Description: The contextCategory property is the set of associations to ContextCategories within an aligned model to the Classification Scheme Profile. Description: Classifiers stereotyped as ContextCategory provide a value which information may be classified, and associations to other ContextCategories. Description: The value property provides the name, or id, actually used for classification wthin a model aligned to the Classification Scheme Profile. Description: The AssociatedCategory property provides associations between ContextCategories. Description: The Classified property provides the ability to associate classifiable information. Description: Classifiers stereotyped as Classifiable represent an entity which can be classified within a ContextCategory. Description: The categorization property represents the ContextCategories which the entity is associated.
