To define Cartography node relationships in Neo4j, you attach connections to nodes via existing schema fields using standard edges, or by flattening list-based targets into multiple edges for scalable associations.

A MatchLink in Cartography connects two existing node types with rich metadata, primarily used to map data from separate sources or model complex cross-source links that standard edges cannot handle.

You create one-to-many relationships in a Cartography graph model by flattening list-based targets into multiple edges, enabling scalable associations across tenants and shared resources.

Yes, Cartography supports cross-module mappings across multiple data sources by using MatchLinks to connect existing node types, enabling rich graph models and composable architectures.

To clean up Cartography node relationships when data changes, you use provided maintenance routines to reset and re-load relationships, ensuring your resource graph stays synchronized with updated sources.

Yes, Cartography uses Neo4j as its graph database to store nodes and define relationships, making it the required environment for implementing MatchLinks and maintaining resource graphs.
