+title:  Discoverable resources for every ISO/TC 211 standard
+date:   2026-06-11 12:00:00 +0800
+categories: update
+---
+
+Every ISO/TC 211 standard comes with more than just a schema file. There are
+codelist dictionaries, example instances, Schematron validation rules, XSLT
+transforms, and downloadable packages. Until now these resources were scattered
+across the repository — visible only if you knew the right directory path.
+
+As of today, all resources are discoverable through the site itself.
+
+## What changed
+
+**The homepage now has a Resources section.** Six cards link to the major
+resource categories: [Codelist Catalogues](/resources/codelists/), Example
+Instances, XSLT Transforms, Schematron Rules, Download Packages, and the raw
+GitHub repository. Each card links directly to the filtered resource catalog.
+
+**The resource catalog is filterable.** The [/resources/](/resources/) page
+lets you filter by resource type and by standard. Looking for all Schematron
+rules for ISO 19115? Two clicks. Looking for XML examples for ISO 19157? Same.
+
+**Per-standard pages show their resources.** Each standard listing page (for
+example, [ISO 19115-1](/19115/-1/)) shows a resources section with counts and
+direct links to that standard's codelists, examples, transforms, and bundles.
+
+**The navigation provides clear paths.** The header nav now includes
+About, Resources, Codelists, and News — giving every major section a top-level
+entry point.
+
+## Why it matters
+
+ISO/TC 211 schemas are used by a wide range of communities — national
+geospatial agencies, INSPIRE implementers, OGC standards developers, and
+metadata tool builders. These users need more than the XSD file. They need
+to know what values a codelist allows, where to find example instances, and
+whether Schematron rules exist for a given module.
+
+Making these resources discoverable means:
+
+* **Implementers** can find example instances and codelist values without
+  digging through the repository
+* **Validators** can locate Schematron rules and understand constraints beyond
+  XSD
+* **Tool developers** can discover transforms for migrating between versions
+* **Standard editors** can see all resources for their standard in one place
+
+## The full picture
+
+The site now provides three complementary ways to find resources:
+
+1. **Homepage cards** — quick access to the six major resource categories
+2. **Resource catalog** — searchable and filterable by standard and type
+3. **Standard pages** — resources listed alongside their schema packages
+
+Combined with yesterday's [persistent codelist URLs](/update/2026/06/10/codelist-catalogues.html),
+every category of ISO/TC 211 resource now has a stable, browseable home.
