Open OSINT Knowledge Graph
A versioned semantic reference layer connecting OSINT source families, investigative tasks, techniques, tools, risks and intelligence outputs.
What this graph represents
A compact semantic layer above the product catalog. It explains how OSINT inputs, tasks, methods, tooling, risks and outputs connect without replacing the existing catalog taxonomy.
Stable concepts
Every concept has a stable identifier such astask:entity-resolutionorrisk:privacy.
Explicit relations
Relations are first-class records with predicates and descriptions, making the graph reviewable and exportable.
Risk remains visible
Risk concepts are part of the graph rather than footnotes, so methods and outputs remain tied to operational and ethical constraints.
Node families
This reference graph connects core OSINT concepts and workflows. It is a curated selection, not an exhaustive model of the field.

How the graph reads
The core chain is source → task → technique → tool / risk → output. Relations remain directional and descriptive.
Example relationships
