Chapter 1, Language Architecture of the UML 2.0: Infrastructure explains how the UML 2.0: Infrastructure is architecturally
aligned with the UML 2.0: Superstructure that complements it. It also explains how the InfrastructureLibrary defined in the
UML 2.0: Infrastructure can be strictly reused by MOF 2.0 specifications.
It is the intent that the unified MOF 2.0 Core specification must be architecturally aligned with the UML 2.0: Infrastructure
part of this specification. Similarly, the unified UML 2.0 Diagram Interchange specification must be architecturally aligned
with the UML 2.0: Superstructure part of this specification.
The OMG’s Model Driven Architecture (MDA) initiative is an evolving conceptual architecture for a set of industry-wide technology
specifications that will support a model-driven approach to software development. Although MDA is not itself a technology
specification, it represents an important approach and a plan to achieve a cohesive set of model-driven technology specifications.
This specification’s support for MDA is discussed in the UML 2.0: Infrastructure Appendix B, Support for Model Driven Architecture.
