Characteristics

• Schema-Driven: Applications declaratively define Templates and Relations. This represents the data structure of your application. This can be further enhanced by Unions.

• Schema-first: Applications are defined declaratively via a builder DSL that compiles to immutable definition objects (similar to GraphQL SDL → schema)

• Hierarchical: Items form a rooted tree structure with parent-child relationships and key-path addressing

• Event-driven: First-class event primitives with listener registration, bubble propagation up the hierarchy, and cron scheduling

• CQRS: Strict separation between read paths (Query/ReadRuntimeInstance) and write paths (Mutation/WriteRuntimeInstance)

• Relational: Typed relations between templates with explicit cardinality constraints (1:1, 1:N, N:1, N:N)

• Stateful: Templates embed finite state machines with typed transitions

• Role-based: Declarative RBAC at both application and entity levels with grant-based property access

• Modular: Applications compose via dependency injection with topological resolution

• Multi-tenant: All entities (Item) are workspace-scoped with tenant isolation at the data layer
