Register a Catalog in the Portolan Registry

You are helping a user add their Portolan catalog to the portolan-registry by opening a pull request. The registry crawls and validates submitted catalogs, then exports their metadata. (Portolan uses STAC to organize its catalog.json, but a Portolan catalog is its own thing — don't call it a STAC catalog.)

Key fact: submitters provide only the URL

A registry entry is a single YAML file with one field:

url: https://example.com/stac/catalog.json

CI auto-extracts everything else (title, description, bbox, license, counts, etc.) by crawling the catalog. Never add other fields or invent metadata — the schema forbids it (additionalProperties: false).

Step 1: Validate the catalog URL
