zinsschema

Zinsschema is a schema language and tooling ecosystem used to describe data models, validation rules, and serialization contracts. It provides a declarative syntax to define primitive types, composite types, constraints, and relationships between entities, enabling consistency across services and data stores. Zinsschema schemas can be versioned, evolved, and validated against a registry to ensure compatibility.

The language supports modular schemas, type aliases, enumerations, optional and nullable fields, and references to other schemas. It allows defining constraints such as range, length, and pattern, as well as custom predicates, and supports inheritance and composition to build complex data models.

Tooling includes a compiler or processor that can generate code bindings in multiple programming languages and a runtime validator that checks input data or configuration against a defined schema. It can also emit documentation, tests, or mock data from schemas.

Applications include API design, configuration management, data interchange, and microservices architectures. By providing a single source of truth for data contracts, zinsschema seeks to improve interoperability and evolve schemas safely.

Compared to general-purpose schemas such as JSON Schema or API description formats, zinsschema emphasizes modularity, cross-language code generation, and integration with schema registries. It is used in environments that require consistent data contracts across heterogeneous systems and long-term maintainability of data models.
