GIR XSD Data Toolkit

A practical implementation pack for the GloBE Information Return (GIR): a tax-friendly data dictionary, code lists, repeatability mapping, and a rules-ready validation library designed for corporate tax teams, advisory firms, and software vendors.

📘 Data Dictionary (Excel)
🧩 Code Lists + Dropdown-ready
✅ Repeatability + Scope
🧠 OECD Validation Rules (JSON/CSV)
🌍 Jurisdiction Profiles (v0)

1) GIR Data Dictionary

A practical element-by-element reference for tax and engineering teams.

  • OECD guidance summaries + tax-friendly labels
  • Input vs container identification
  • Required/optional + repeatability
  • XSD types + XPaths for implementation
  • Code lists + dropdown-ready codes

2) OECD Validation Intelligence

Rules-ready OECD error codes mapped to fields and XPaths.

  • Target & reference field mapping
  • Inferred rule types (required_if, not_equal, etc.)
  • Fix hints for implementation / UI guidance
  • Index files for fast API lookup

3) Jurisdiction Packaging Profiles

A configuration layer for jurisdiction wrapper requirements.

  • Export packaging rules (e.g., Japan Summary per subgroup)
  • Portal constraints (encoding, file splits)
  • Extensible as more jurisdictions publish guidance

For Vendors / API Users: Validation Response Format

The Toolkit is designed for API-driven workflows. Validation responses return machine-readable rule IDs and field pointers (XPaths), making it easy to highlight the exact fields that need attention.

{ "submission_id": "subm_123", "profile": "OECD", "status": "invalid", "summary": { "errors": 3, "warnings": 1, "passed_rules": 247 }, "issues": [ { "severity": "error", "error_code": "70106", "rule_id": "…", "rule_type": "not_equal", "scope": "same_container_instance", "target": { "xpath": "/…/OtherTIN", "instance_id": "summary:subgroup:GIR1101:JP-TIN-AAA", "value": "JP123456789" }, "reference": { "xpath": "/…/TIN", "instance_id": "summary:subgroup:GIR1101:JP-TIN-AAA", "value": "JP123456789" }, "message": "OtherTIN must not equal TIN.", "fix_hint": "Ensure OtherTIN is different from TIN." } ] }
How vendors typically use this: map the returned XPath + instance_id to your internal model, surface the message inline, and include the fix hint in UI or logs.
