Site redesigned with modern URI dereferencing and data-driven architecture

May 05, 2026

The ISO/TC 211 Standards site has been redesigned to serve as a dedicated URI dereferencing service for ISO geographic information standards.

Purpose

ISO/TC 211 standards define requirements classes, conformance classes, and conformance tests, each identified by a permanent URI (e.g. /19115/-3/2/req/metadata-core/basic). This site ensures every such URI resolves to a page with structured metadata, cross-references between related provisions, and direct links to ISO.org.

In the future, the site may also host implementation guidance for each provision.

What’s new

  • URI dereferencing service — Every URI used in a published ISO/TC 211 standard for requirements classes, conformance classes, and conformance tests now resolves to a dedicated page with structured metadata, cross-references, and direct links to ISO.org.

  • Data-driven standards — Standards are defined entirely through YAML data files. Adding a new standard requires only dropping -rc.yaml and -cc.yaml files into the data directory—no HTML authoring or configuration changes needed. The generator automatically creates index pages, provision pages, homepage listings, and example URIs from the data.

  • Model-driven architecture — Provision data is loaded through the modspec-ruby library, providing OGC ModSpec-compliant models for requirements classes, conformance classes, normative statements, and conformance tests.

  • ISO.org integration — Each standard page links directly to its ISO.org listing and full-text preview, making it easy to access the complete published document.

  • Complete standards catalog — The site now lists all published ISO/TC 211 standards, auto-discovered from ISO public metadata. Standards are organized into three categories:

  • Supported standards — those with URI-identified requirements and conformance classes (data provided as YAML):

    • ISO 19115-3:2023 — Geographic information — Metadata — Part 3: XML schema implementation for fundamental concepts

    • ISO 19135:2026 — Procedures for registration

    • ISO 19112:2019 — Spatial referencing by geographic identifiers

  • Standards without harmonized URI requirements — standards that do not specify requirements utilizing the ISO/TC 211 Harmonized URI scheme

  • Standards awaiting data upload — identified standards where data has not yet been provided

New standards are discovered automatically via a weekly workflow that creates pull requests when new publications are detected.
