PlanetGraph Recipes: Warm Introductions

This file describes one example use case implemented on top of PlanetGraph's generic graph model.

Generic model reminder

• nodes represent domain entities
• edges represent relationships between entities
• properties can be attached to either nodes or edges

Recipe 1: Shared employer bridge

Intent

• Find people connected through a common company.

Cypher

MATCH (source:Person)-[:worked_for]->(company:Company)<-[:worked_for]-(target:Person)
RETURN source, company, target
LIMIT 100

Recipe 2: API-based edge filtering by node types

Intent

• Retrieve only people-to-company work edges.

HTTP

GET /api/v1/edges?type=worked_for&source_type=Person&target_type=Company&limit=100

Recipe 3: Expand one person's employer neighbors

Intent

• Explore candidate intro paths around a starting person node.

Cypher

MATCH (p:Person)-[:worked_for]->(c:Company)<-[:worked_for]-(other:Person)
RETURN p, c, other
LIMIT 100

Validation notes

• If results are empty, first inspect available edge types using GET /api/v1/edges.
• Confirm case sensitivity for type labels in your dataset (Person vs person).
