JSON Schema is ubiquitous and critical to our operations, yet so many of us have barely scratched the surface when it comes to putting the specific to work, let alone getting our house in order
JSON Schema defines and validates the world
1 Mastering JSON Schema
JSON Schema is an extensible universal language for defining the structure, meaning, relationship, and hyperlink navigation of JSON documents, and there is a lot more that meets the eye. Whether you are just getting started, or want to explore advanced topics like annotations and custom vocabularies, we have the best resources to get you from zero to hero, fast.

JSON Schema Video Course
A comprehensive self-paced video course exploring in-depth every aspect of JSON and JSON Schema, from basic keywords, to annotations, dynamic references, the evaluation model, and ontology design. If you want to become a JSON Schema expert, and/or want to develop your own compliant JSON Schema implementation, this course is for you
2 Developing with JSON Schema
Writing a few simple schemas is an easy task. However, developing and maintaining ontologies consisting of hundreds of complex schemas can be extremely challenging. Our suite of tools encapsulates our experience consulting with world-class ontologies. It is what we use to get the job done, and they are available for you too.
JSON Schema CLI
The ultra compliant swiss-army knife for working with JSON Schema at scale. It includes a schema test runner and validator to exercise your schemas, tracing support for debugging complex schemas, and various other utilities like a formatter, linter, bundler, and more

JSON Schema Debugger
A cross-platform desktop application to visually step-through JSON Schema validation. Perfect for working with complex schemas, debugging when things go wrong or when they go unexpectedly right
JSON Schema Standard Library
A growing collection of carefully crafted reusable schemas so you don't have to reinvent the wheel, getting rid of a lot of the boilerplate when defining ontologies and API specifications
3 Deploying JSON Schema
Whether you are deploying within your organisation or to the world, distributing and operating JSON Schema in production comes with its own challenges. From keeping up with new versions of the specification, all the way to hosting schemas in a compliant manner that guarantees interoperability with other systems and code editors, we got you covered.
AlterSchema
Automatically upgrade JSON Schema across versions of the specification to target real-world systems that are often using a diverse set of JSON Schema versions. Downgrade support and Apache Avro conversion coming soon
