dr-json-ld.com Visit website

Editorial interest 84/100 Selection signal · not a rating of the site

A workshop and toolchain for authoring, inspecting, testing, versioning, and publishing JSON-LD contexts.

Landing page captured for the 2026-09-20 issue.

For: JSON-LD authors and linked-data reviewers
Worth noticing: Findings carry stable rule IDs, JSON Pointers, and line-and-column locations in the authored file.

Field notes

The project separates semantic authoring from generated JSON-LD output, with the authored YAML file serving as the review surface. Its diagnostics distinguish missing terms, undeclared prefixes, coercion problems, and other lossiness, while its comparison workflow reads versions from lockfiles and matches elements by ID. The site also describes vendored contexts with recorded hashes for offline use.
