What is a .json file?
JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format representing objects, arrays, strings, numbers, booleans, and null. It is language-independent, human-readable, and the dominant format for web APIs and configuration. It requires a single well-formed root value.
How to use this file
Use an example JSON file to test parsers and serializers, schema validation, Unicode and number-precision handling, and API request or response processing.
How to use this file for testing
“Well-Known — Assetlinks Extra” is a deterministic Novus Examples fixture for Web assets, JSON parsing. Favicons, web app manifests, service workers, robots and sitemap files, Open Graph images, and .well-known resources, for testing web tooling, crawlers, PWA installers, and asset pipelines.
Documented properties for this file: well-known. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.
Web-platform fixtures are standards-compliant samples against fictional example.com data. Test crawlers, PWA installers and manifest validators, favicon/icon pipelines, service-worker registration, or .well-known parsers against the documented structure.

- jsonassetlinks.json (Android)An Android Digital Asset Links file granting app-link handling to a package via a certificate fingerprint (sample) — for testing assetlinks.json parsers and App Links verification.
- jsonhost-meta.json (JRD, JSON form)The JSON Resource Descriptor twin of the XRD host-meta: identical subject, alias, expiry, property and three links, expressed with lower-case JSON member names. For testing XRD-to-JRD conversion against a known answer.
- jsonMatrix client discovery (m.homeserver)The client-side twin of the Matrix delegation pair: homeserver and identity server base URLs plus an unregistered vendor key, which clients must carry through rather than reject. For testing discovery and unknown-member tolerance.
- jsonMatrix server delegation (m.server)The one-member server-delegation document that lets example.com host its Matrix homeserver at matrix.example.com:8448 without changing user IDs. For testing federation discovery and explicit-port handling.
