Features

• A carefully written language specification.
• A minimal data definition language based on algebraic sum and product types.
• Strong versioning as a core aspect of the language.
• A small, easily auditable codebase with a heavy use of modularity for correctness.
• Generates simple, readable, reflection-free Java code.
• A small footprint; the generated Java code consists of trivial record definitions and incredibly simple and straightforward code to serialize and deserialize values.
• Platform independence. No platform-dependent code is included in any form.
• Suitable for use in security-critical environments: Serialization code is immune to the usual serialization vulnerabilities such as type confusion, resource exhaustion, exponential parse times, and etc.
• An extensive automated test suite with high coverage.
• OSGi-ready.
• JPMS-ready.
• ISC license.
