Heimdall (real-time graph audit and history)
Heimdall is a comprehensive solution for full graph audit and history tracking of the Open Native Graph Database (the free and open source Neo4j project) with the ability to query through audit entries and through history at any point in time. This non-invasive, always online audit and history solution makes it possible to take graph-centric solutions from the lab and deploy in production.
The installation is non-invasive to your existing graph database and results in no changes to the source graph database for which history and audit records are being kept. To get started you simply add the Heimdall plugin to your existing neo4j-based graph database installation, which pushes every change that occurs to the Heimdall Service to be processed and stored in the Heimdall audit and history graph.
