xwschema 0.4.0.11

Convenience wrapper for exonware-xwschema - provides 'import xwschema' alias

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.

📦 Install

pip install exonware-xwschema
pip install exonware-xwschema[lazy]
pip install exonware-xwschema[full]

---

🚀 Quick start

from exonware.xwschema import *

# Define and validate schemas; pair with xwaction for workflow validation
# See docs/ and REF_* for API and examples

See docs/ for usage, REF_*, and GUIDE_01_USAGE when present.

🎯 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.

✨ What you get

Area	Contents
Validation	Constraint checks and structured errors.
Schema	Dynamic composition, evolution, versioning.
Schema catalog	DDL-style helpers (create_schema, alter_schema, drop_schema) and apply_migration for evolution; JSON-backed catalog for schema-on-write with xwstorage/XWDB. See docs/REF_15_API.md.
Integration	xwaction workflows and other eXonware packages.

Current phase: docs/REF_22_PROJECT.md or docs/.

🌐 Ecosystem functional contributions

xwschema provides validation contracts; sibling libs define where those contracts are applied in real systems. You can use xwschema standalone for schema definition and validation in any Python project. Integrating with the wider XW platform is optional and most useful for enterprise and mission-critical environments where validation must stay consistent across self-managed services.

Supporting XW lib	What it provides to xwschema usage	Functional requirement it satisfies
XWAction	Action input/output validation hooks tied to schema definitions.	Contract-safe automation and endpoint execution.
XWEntity	Entity model contracts bound to schema rules.	Domain model correctness and controlled schema evolution.
XWData	Format-agnostic data ingestion where schemas validate transformed payloads.	Cross-format validation without rewriting rule logic per format.
XWStorage	Schema catalog/migration integration for persisted data systems.	Schema-on-write and migration governance for storage-backed workloads.
XWSystem	Core runtime/error utility layer for validators and schema tooling.	Consistent validation behavior and diagnostics across stack packages.
XWAPI / XWAuth	Request, response, and policy-rule validation at API/auth boundaries.	Safer public interfaces and security policy correctness.

Competitive edge: schema rules become a reusable platform contract across APIs, storage, entities, and workflows instead of living as isolated validators in each service.
