Schema browser redesigned with data-driven architecture and resource catalog

The ISO/TC 211 Schemas site has been redesigned with a modern interface, fully data-driven architecture, and a comprehensive resource catalog.

What’s new

• Interactive XSD schema browsers – Each XML schema package now has a dedicated interactive browser powered by LutaML XSD, providing full listings of elements, complex types, simple types, and attribute groups with cross-references.

• Interactive JSON schema browsers – JSON schema packages now have their own interactive browsers powered by LutaML JSON Schema, showing schema definitions, properties, references, and example data.

• Data-driven resource catalog – All resources — XSLT transforms, Schematron validation rules, XML and JSON examples, codelist dictionaries, and download packages — are now auto-discovered from the filesystem and presented in a filterable catalog at /resources/.

• Reorganized schema repository – The underlying schemas repository has been restructured with consistent directory naming (standard/-part/module/version/), separated examples, consolidated per-standard resources, and proper ZIP bundles.

URL structure

All schemas are served at canonical top-level URLs with no /schemas/ prefix. This is the URL pattern that XML parsers, validators, and schemaLocation attributes rely on.

Legacy paths

Some schemas were previously available at paths without the part number (e.g., /19155/gpi/1.0/ instead of /19155/-/gpi/1.0/). These old paths are redirected to the canonical URLs above. XML data files are served as actual file copies at the old path (since XML parsers cannot follow HTML redirects).

Supported standards

The site currently provides schema browsers for:

Additional standards will be added as they become available.
