For Regulatory Industries | Fully Standards Compliant | Premium Support
A growing library of battle-tested JSON Schemas implementing standards from ISO, IETF, IEC, W3C, XBRL, and more. Ready to plug into your OpenAPI specs and API Gateways. Eliminate years of schema development, ongoing maintenance, and the regulatory risks of implementing standards yourself.
Led by a member of the JSON Schema Technical Steering Committee
These are the standards we are covering so far:
Regulated Industries Can't Afford Schema Implementation Risk
Eliminate compliance exposure, implementation complexity, and maintenance burden
Schema errors become regulatory violations
In regulated industries, validation failures aren't technical bugs; they're compliance breaches. When schemas accept malformed data or fail to enforce constraints, you're exposed to regulatory penalties and audit failures. Hand-crafted schemas rarely capture every edge case that auditors scrutinise.
Industry standards often exist only in XML
Many standards provide XML schemas, but often JSON implementations are non-existent or poorly documented. Translating XML Schema to JSON Schema requires deep dual-format expertise and significant time investment. Most organisations can't do it or burn extraordinary resources trying.
Standards evolve, and your schemas must too
Industry standards release updates. Regulations change. JSON Schema and OpenAPI change too. Maintaining schema accuracy isn't a one-time project; it's perpetual expert work. We track updates, maintain backward compatibility, and ensure your schemas stay compliant as regulations evolve.
Pricing
Sourcemeta is led by Juan Cruz Viotti, a member of the Technical Steering Committee that defines and maintains the JSON Schema specification itself. You are not buying interpretation, but definitive expertise from the source. This level of implementation quality and support simply doesn't exist elsewhere.

What's the Alternative?
This is not about $ref. It's about having the in-house talent and correctly implementing dozens of specifications, reading paywalled standards, handling edge cases, keeping up with updates, and obsessively guaranteeing compliance.

I'm Juan Cruz Viotti, founder of Sourcemeta, member of the JSON Schema Technical Steering Committee, O'Reilly author, and award-winning University of Oxford alumnus.
I'd love to discuss how JSON Schema, OpenAPI, and Sourcemeta tooling can help you build world class APIs.
Industry leaders rely on our tooling
"This is definitely going to become an incredibly important reference library for defining concepts using best in class standards"
"This is a terrific project and should be a standard subscription for any enterprise working with JSON Schema"
"This aligns exactly with my thinking! OpenAPI should not include schemas but should reference them externally from a source of truth like this one"
"Before this library, defining foundational schemas in an enterprise was a time-consuming, error-prone task that could result in inconsistencies. This library is a game-changer, delivering huge time savings while ensuring improved API consistency and strong governance of API definition files"
"Right now there is a big disconnect between ontology work and API work. This project has the potential to bridge that gap by making widely used ontologies available on JSON Schema"
