AAS - Neo4j

This project is a proof of concept for the mapping of the Asset Administration Shell (AAS) in a Neo4J graph database.

How it works

It reads an AAS and generates a Cypher clauses to create the graph in Neo4j. These clauses are then executed in the Neo4j database.

AAS - Neo4j Mapping

1. Referable = Node
2. AssetInformation = Node
3. If Referable contains other Referable -> Relationship
4. Reference is a Relationship

Limitation or Not implemented

• Only basic Deserialization from Neo4j is implemented
• AAS Query Language Mapping to Cypher

Getting started

Run Neo4J server

YOUR_PATH_TO_NEO4J\neo4j-community-5.23.0\bin\neo4j console

Add the AAS to Neo4j

from aas_mapping.aasjson2neo import AASNeo4JClient

aas_neo4j_client = AASNeo4JClient(uri="bolt://localhost:7687", user="neo4j", password="password")
aas_neo4j_client.upload_aas_json("SOME_AAS.json")

Show all nodes in Neo4j Browser

MATCH (n)
RETURN n;
