The major components within an Architecture Repository are as follows:
The Architecture Metamodel describes the organizationally tailored application of an architecture framework, including a metamodel for architecture content.
The Architecture Capability defines the parameters, structures, and processes that support governance of the Architecture Repository.
The Architecture Landscape shows an architectural view of the building blocks that are in use within the organization today (e.g., a list of the live applications). The landscape is likely to exist at multiple levels of abstraction to suit different architecture objectives.
The Standards Information Base (SIB) captures the standards with which new architectures must comply, which may include industry standards, selected products and services from suppliers, or shared services already deployed within the organization.
The Reference Library provides guidelines, templates, patterns, and other forms of reference material that can be leveraged in order to accelerate the creation of new architectures for the enterprise.
The Governance Log provides a record of governance activity across the enterprise.
