Feed twin - JSON Feed 1.1

The third twin: the same four articles as JSON Feed 1.1, using the 1.1 `authors` array rather than the 1.0 singular form, with ids, URLs, summaries, HTML bodies and timestamps identical to the RSS and Atom files. The reference output for an XML-to-JSON feed converter.

Testing contract

Reference control

Scenario: Convert the RSS or Atom twin to JSON Feed and diff against this file.
Expected result: The converter emits four items whose id, url, title, summary, content_html and date_published match this document field for field, and uses the plural `authors` member required by version 1.1.

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

“Feed twin - JSON Feed 1.1” is a deterministic Novus Examples fixture for Web assets, Feed parsing, JSON parsing, Conversion testing. 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: seed 70400 · JSON Feed 1.1. 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.
