`atag.export.jgf`

Exports a graph in JGF (JSON Graph Format) from a list of nodes and relationships.

Signature

atag.export.jgf(nodes, relationships) :: STRING

nodes: List of nodes (List<Node>)
relationships: List of relationships (List<Relationship>)
Returns: JGF string (JSON)

Example

Export a subgraph with APOC and convert it to JGF format:

MATCH (start:Person {name: 'Alice'})
CALL apoc.path.subgraphAll(start, {maxLevel:2}) YIELD nodes, relationships
RETURN atag.export.jgf(nodes, relationships) AS jgf

The result is a JSON string in JGF format describing the subgraph.

Features

Nodes and relationships are exported with their properties and labels.
Supports various property types (String, Integer, Long, Double, Boolean, LocalDate).

Typical Usage
