ARD entry validity

What it checks

For each entry in the site’s ARD catalog, the extension checks the four terms the specification requires:

• an identifier that starts with urn:air: and whose publisher segment (the part after urn:air:) is the domain being scanned,
• a non-empty displayName,
• a type that looks like a media type (it contains a /), and
• exactly one of url or data, never both and never neither.

The domain anchoring matters because it is what lets a registry tie an entry to whoever served it.

Results

Status	When
Pass	Every entry carries all the required terms
Warn	One or more entries are missing required terms (up to four are listed as evidence)
Warn	The catalog is published but lists no entries
N/A	There is no ARD catalog, or it could not be read

How to fix

Fix each entry named in the evidence. A valid entry for example.com:

{
  "identifier": "urn:air:example.com:api:orders",
  "displayName": "Orders API",
  "type": "application/openapi+json",
  "url": "https://example.com/openapi.json"
}

Use data instead of url only when you embed the resource’s description inline, and never set both.
