exonware-xwschema 0.4.0.7

Schema validation and data structure definition library

xwschema

Define once, validate everywhere.
xwschema lets you describe schema rules and validate data across different input formats and structures with one consistent validation layer.

You can take schema definitions from common formats (for example JSON-style or XML-style representations), then validate heterogeneous payloads and models without rewriting validation logic per format.

Why developers use xwschema

• Schema portability - keep business validation rules stable while data formats vary.
• Cross-format validation - validate different payload styles through one schema engine.
• Extensible model surface - grow new format adapters and schema types without redesigning core validation.
• Works with your stack - use standalone or pair with xwaction/xwdata workflows.
