Meridian Health Partners · Governance Graph

Ontology Manager

Define object types, link types, and actions on the governance graph. Reads and writes the live Neo4j schema layer.
connecting to Neo4j...

Schema browser

The metamodel: object types with typed properties, link types with endpoints and cardinality. Stored as meta nodes in the graph, kept apart from instance data.

Object types

Link types

Select a type on the left.

Data explorer

Browse instances by type, search, and follow links between nodes.

Pick a type, then a row.

Graph view

The live instance graph, straight from Neo4j. Commits through the action runner appear here. Click a node to open it in the Data explorer.

Findings

The tiered HIPAA Security Rule gap analysis, run live against the graph. Commit a control or a risk acceptance in the action runner, rerun, and watch the findings change.

Run the analysis to see current findings.

Ask the graph

Natural language in, grounded answer out: the backend generates Cypher, the read-only guardrail checks it, the live graph answers, and the reply is synthesized only from returned rows. The API key stays on the server.

Model access is unavailable here. Enter an Anthropic API key to ask from this browser. The key stays in memory unless you choose to remember it; remembered keys are readable in this browser, personal machines only.

Action runner

Run a governed mutation. Preview shows what would change, nothing is written until you commit.

Actions

Select an action.

Action types

Define parameterized Cypher mutations with validation rules. Templates are linted before they can be saved: parameter placeholders only, no schema commands, no metamodel writes.

Defined actions

Select an action type, or create one.
