A Foundation Architecture consists of generic components, inter-relationships, principles, and guidelines that provide a foundation on which more specific architectures can be built. Generic building blocks, their inter-relationships with other building blocks, combined with the principles and guidelines that provide a foundation on which more specific architectures can be built.

According to TOGAF, a characteristic of a Foundation Architecture is: C. It contains building blocks and their corresponding standards. A Foundation Architecture in TOGAF refers to an architecture that serves as a baseline or starting point for developing specific architectures within an organization. It provides a set of reusable building blocks, which are modular components or assets that can be combined or customized to create architectures tailored to specific needs. These building blocks are accompanied by their corresponding standards, guidelines, and specifications, ensuring consistency and interoperability across the organization. The Foundation Architecture serves as a reference architecture that establishes a common language, structure, and framework for developing and aligning other architectures within the enterprise.
