### STSCDT Representation--Generic Context Management Packages and Meta-Concepts (RH2)
#### 3.2.1 Generic Concept Package and Meta-Concepts  
The GeneriConceptPackage contains the Generic Concept Meta-Model specifying the generic meta-concepts used in the specification and modeling of other meta-concepts (Figure 5).  
AttributeConcept is a universal meta-concept enabling the specification and meta-modeling of the semantic dimension of an arbitrary meta-concept. It is potentially composite over the Cartesian product StructuredAttribute meta-concept supporting the specification and meta-modeling of structured attributes over ContainerAttrib and ContainedAttrib strong dependency relations. The AttributeConcept meta-concept may participate in the identification (IdentifyByAttrib strong dependency), extension (ExtByAttrib weak dependency), and classification (ScExtendedAttributes with Classifier? set true) of a StructuredConcept and all its specializations.  
Figure 5: The reusable StructuredConcept meta-concept specifies three essential reusable meta-concepts with an open semantic structure: StructuredConcept, Attributes, and ClassificationMechanism meta-concepts.  
The StructuredConcept is an identity-opened, semantically opened, classification-opened, and connectivity-enabling generic meta-concept, enabling specification and modeling of other specialized meta-concepts. The inheritance mechanism aids the simplicity of derived meta-concepts and related meta-models. Any meta-concept that inherits a StructuredConcept inherits its structure and behavior. Specialized meta-concepts expand through meta-model-to-model transformation only at a model level.  
The identity-opened feature relies on the AttributeConcept meta-concept and enables data-driven clustering and identification of a StructuredConcept meta-concept through a strong dependency relation (IdentifyByAttrib). A strong dependency relation enables the formation of the composite concept's primary identifier and the cascading proliferation of the type-identifier to the arbitrary model level. The cascading composite primary identifier proliferation enables meta-model to platform-dependent model-instance transformations with either SQL or NoSQL data-repository types and fosters the elimination of explicit joins in business logic specifications.  
The semantically opened feature relies on the ScExtendeAttributes meta-concept and enables data-driven configurations of arbitrary complex attribute collections extending the StructuredConcept over strong dependency ExtAttributes relation. The ScExtendedAttributes meta-concept is a container for data or meta-data attributes used to specify the semantics of an arbitrary specialization.  
The classification-opened feature relies on the ScExtendeAttributes meta-concept resident attribute marked as Classifier? and enables data-driven configurations of arbitrary complex classification mechanisms extending the StructuredConcept over strong dependency ExtAttributes relation and serving for indexing mechanism creation.  
The connectivity-enabling feature assumes the ability to form different tracing paths and support the configuration building of an arbitrary StructuredConcept. It supports the following:  
* successor-predecessor connectivity (ScSuccessor-ScPredecessor relations among StructuredConcepts);
* mash-supportive connectivity over Cartesian product MashRelated meta-concept enabling specification and modeling of an arbitrary mash structure over SCSource and SCDestination strong dependency relations with PayBackAttrib-defined cost or benefit value when traversing from source (SCSource) to destination (SCDestination) StructuredConcept;
* hierarchy connectivity (HierarchyRelated multilevel composition of StructuredConcept, enabling the formation of arbitrary tree topologies following the hierarchy-related leveling of a StructuredConcept by InHierarchy-related StructureConcepts).  
In any connectivity, it is essential to guarantee referential integrity by implicit, structure-based, or explicit, behavior-based mechanisms.
