  yourself.
importer import.
importer model name

Import in neo4j

You can load the generated json file with this command

CALL apoc.load.json('file:///test-graph.json') YIELD value
WITH value.nodes AS nodes, value.relationships AS rels
UNWIND nodes AS n
CALL apoc.create.node(n.labels, apoc.map.setKey(n.properties, 'id', n.id)) YIELD node
WITH rels, apoc.map.fromPairs(COLLECT([n.id, node])) AS nMap
UNWIND rels AS r
WITH r, nMap[TOSTRING(r.startNode)] AS startNode, nMap[TOSTRING(r.endNode)] AS endNode
WHERE startNode IS NOT NULL and endNode IS NOT NULL 
CALL apoc.create.relationship(startNode, r.type, r.properties, endNode) YIELD rel
RETURN rel

JSON model format

Goal

Import and Export Fame model the following format

{
  "name":"modelName",
  "nodes": [
    {
      "id": 3510982, 
      "labels": ["FAMIX.Class"],
      "properties": { "isStub": false, "isInterface": false, "numberOfLinesOfCode": 0, "name": "a" }
    },
    {
      "id": 3510983, 
      "labels": ["FAMIX.Attribute"],
      "properties": { "name": "a1", "hasClassScope": false, "numberOfLinesOfCode": -1, "isStub": false }
    },
    {
      "id": 3510984, 
      "labels": ["FAMIX.Attribute"],
      "properties": { "name": "a2", "hasClassScope": false, "numberOfLinesOfCode": -1, "isStub": false }
    }
  ],
  "relationships": [
    { "type": "parentType", "startNode": 3510983, "endNode": 3510982, "properties": {} },
    { "type": "parentType", "startNode": 3510984, "endNode": 3510982, "properties": {} }
  ]
}
