1. Key Advancements in JSON Schema Draft 2020-12
Draft 2020-12 introduces unified dynamic referencing (`$dynamicAnchor`, `$dynamicRef`) and full vocabulary unification with OpenAPI 3.1. Our generator inspects primitives, arrays, and nested structures to produce compliant schema contracts automatically.

"$schema": "https://json-schema.org/draft/2020-12/schema",
"$id": "https://example.com/product.schema.json",
"type": "object",
"properties": {
"productId": { "type": "integer" },
"productName": { "type": "string" },

2. IETF RFC 9535 JSONPath Comparison Operators
Unlike legacy Goessner JSONPath, RFC 9535 eliminates arbitrary script evaluation vulnerabilities. Operators like root `$`, recursive descent `..`, and filter expressions `[?@.price < 10]` execute safely with predictable deterministic performance.
3. Zero-Allocation In-Memory Processing
Production schemas often describe confidential enterprise databases or sensitive client payload structures. DevOmniTools evaluates queries and builds schema models entirely within local volatile RAM with zero telemetry or network calls.
4. Automated Format Heuristics & Type Validation
The generator classifies string formats (date-time, uuid, uri, email) and inspects array items to determine whether homogeneous item definitions or polymorphic anyOf schemas should be produced.
