Enterprise-Ready Features
for Complex Spatial Workflows
Workflow Engine
Terragnos Core Engine provides a powerful workflow system that enables organizations to define custom state machines for spatial objects. Configure transitions, guards, and automated actions to streamline complex business processes.
Every workflow transition is fully audited, supports conditional logic based on object attributes and spatial relationships, and integrates seamlessly with your existing authentication and authorization systems through our BYOA (Bring Your Own Auth) architecture.

Schema Registry
Define and evolve object types with full version control and migration support. The Schema Registry stores JSON Schema definitions with Zod-compatible validation rules, enabling complex field types including arrays, unions, and nested objects.
Schema changes follow a governance workflow: draft → sandbox validation → production publication. Compatibility checks ensure backward compatibility, and automatic SDK generation keeps client libraries in sync with schema changes across TypeScript, Python, and C#.
