Jormungandr
Canon Governance and Enforcement
The governance you built doesn’t have to decay. Jormungandr wraps around your data landscape and enforces canonical definitions continuously — detecting drift before it becomes divergence.
Governance Decays
A Ratatosk workshop produces a perfect semantic snapshot. But schemas evolve. Teams add columns. Integrations change field mappings. Definitions drift. Within months, the canonical model and reality diverge.
Schema Drift
New columns appear. Old columns change type. Tables are added without governance review. Each change is small; the cumulative effect is structural divergence.
Definition Erosion
A field labeled ‘Available Inventory’ meant unrestricted stock during the workshop. Six months later, someone includes quality-hold stock. The label didn’t change — the meaning did.
Synonym Proliferation
New systems introduce new names for existing concepts. ‘Customer’ becomes ‘Account’ becomes ‘Client’ becomes ‘Business Partner’. Without enforcement, the vocabulary fragments.
Governance Fatigue
The workshop was energizing. The action plan was clear. But without continuous enforcement, governance becomes a memory — not a practice.
Governance That Persists
Jormungandr converts a one-time governance discovery into a sustained enforcement practice. It watches your schemas, validates compliance, and surfaces drift — deterministically, continuously, and without requiring another workshop.
Immutable Versioning
The canonical model is versioned like code. Every change creates a new version with an explicit diff. Previous versions are never modified. Any version can be designated as the active validation target, and rollback is always possible.
Continuous Validation
Live schemas are validated against canonical definitions on a continuous basis. When a column is added, removed, renamed, or retyped without governance approval, Jormungandr flags it immediately — not during the next migration, not during the next audit, but now.
System-Agnostic
Like every tool in the Mimir Labs suite, Jormungandr enforces governance across any enterprise system — not just Yggdrasil. SAP, Oracle, Epicor, NetSuite, custom databases — if it has a schema, Jormungandr can govern it.
Enforcement Capabilities
Canon Registry
Versioned, immutable canonical schema registry. Every table and column definition is tracked with business labels, domain assignments, and full change history.
Schema Drift Detection
Continuous validation of live schemas against canonical definitions. Detects added, removed, renamed, and retyped columns before they cause downstream failures.
Manifest Import
Imports Ratatosk manifests directly as the canonical baseline. No re-discovery required — governance picks up exactly where the workshop left off.
Synonym Dictionaries
Maintains versioned synonym groups that evolve with the organization. Ensures naming conventions stay consistent across systems and teams over time.
Compliance Reporting
Produces audit-ready governance reports showing which systems are compliant, which have drifted, and what specific changes need remediation.
Multi-Tenant Isolation
Every organization’s canonical model is fully isolated with row-level security. Canon definitions, drift history, and validation results never cross tenant boundaries.
The Mimir Platform
Discover. Migrate. Synchronize. Enforce.
Jormungandr is the final layer — the system that ensures everything upstream continues to hold.
Ratatosk
Discover
Extracts semantic meaning from enterprise schemas. Produces the manifest that defines what data means.
Ragnarok
Migrate
Executes structural transformation from legacy to target using the manifest as its source of truth.
Bifrost
Synchronize
Maintains real-time alignment between systems. Propagates changes according to semantic routing rules.
Jormungandr
Enforce
Validates that canonical definitions hold over time. Detects drift, prevents regression, ensures lasting governance.
