Enterprise Knowledge Graph

Semantic representation of an organization's data, files, metadata, business logic, and relationships so AI agents can ground actions in trusted business context.

Key points

• Google Cloud's Knowledge Catalog constructs a unified, dynamic context graph across the business to ground agents in data and semantics ^[src-044].
• Smart Storage and Object Context API tag and enrich files in Google Cloud Storage with metadata before an agent touches them ^[src-044].
• A Knowledge Engine uses Gemini to tag, define logic, and map complex relationships across the enterprise ^[src-044].
• The goal is to provide the missing semantic definition agents need to act on enterprise data rather than only retrieve documents ^[src-044].
• Herk's second-brain maturity model adds a practical threshold: a graph is worth considering when the system needs typed relationships, not just backlinks, such as "works at", "endorsed by", "competitor of", "developed by", or "connects to" ^[src-103].
• The same source warns against graph complexity for its own sake. If a markdown wiki and routing files already answer the real questions, graph infrastructure can be unnecessary overhead ^[src-103].

• Ask Gemini exposes an enterprise knowledge layer directly in collaboration: one session can retrieve across Gmail, Drive, Calendar and Chat, then draft or initiate work ^[src-376].
• Value depends on preserving source permissions and provenance across the graph; broader reach without those controls amplifies leakage and prompt-injection risk ^[src-376].

• OKF v0.2 shows that enterprise knowledge graphs do not require a proprietary graph database as their durable interchange layer: Markdown/YAML bundles can hold typed records and links, while graph visualisation and retrieval indexes remain derived consumers ^[src-377].
• Provenance, generation, verification, freshness and runtime attestation should be represented separately. Collapsing them into one confidence score hides materially different evidence ^[src-377].
• Attested Computation is a promising contract for governed analytics, but the repository does not yet standardise execution receipts, verdicts or sandboxing and therefore does not itself enforce trusted computation ^[src-377].
