When to use

Optimised for: relationship modeling + reasoning + governance over pure vector

Anti-fit: not for purely-vector or simple-RAG use cases (graph adds setup cost)

Pros & cons

Pros

Mature data-governance platform with built-in lineage, taxonomy management, and SHACL validation — important for regulated industries.

Cons

Enterprise-only positioning; very steep learning curve; primarily of interest if you already have a TopQuadrant footprint.

Claims & capabilities

180+ Fortune 500 / regulated-industry customers (taxonomy mgmt, business glossary, reference data); 2025 GenAI Enhanced Search; AI Copilots for SHACL ontology design; Gartner Peer Insights leader for active metadata management
