Here you go: Modeling Primitives: In general, the term "primitive" indicates an entity that is not composed of other entities - for example, a data type of "string". This can apply to modeling (such as UML modeling) as well. Metadata: Data about data. XML tags represent metadata. Concept Constructors: This term is used in a field called "Description Logic". DAML+OIL [1] has a large collection of concept constructors, and Description Logics (DLs) are characterized by a set of constructors provided for building complex concepts and roles from simpler ones.
