Enterprise Architecture often devolves into a fragmented scrapbook of past projects. The TOGAF Architecture Repository offers a conceptual framework — not a tool — for treating architecture as a coherent, reusable body of knowledge. Key components include the Architecture Landscape (Strategic, Segment, and Capability levels), Reference and Standards Libraries, a Governance Repository, and Architecture Building Blocks (ABBs vs SBBs). The post emphasizes that the repository should be selectively curated, actively used, and kept minimal, enabling architecture to be institutional rather than episodic.
