Enterprise Architecture in Higher Education

Here is the taxonomy I use for categorizing the EA artifacts we create. Comments?

Enterprise Architecture Taxonomy (Element-Domain-Component-Artifact)

Architecture Element
The high level architectural description for Applications, Business, Business Continuity, Data, Infrastructure, Presentation and Security containing Architecture Domains. (i.e. An element contains domains)

Architecture Domain
The summary level of architecture describing the models used for each Architecture Element. (i.e. A domain contains components)

Architecture Component
The detailed level of architecture describing the components of an Architecture Domain. (i.e. A component is represented by one or more artifacts)

Architecture Artifact
The populated models representing the current and target architecture for Architecture Components.
