Mirror Test

What your pages tell machines, next to what they should. Paste the page source; nothing leaves this browser.

Home page

View source (Ctrl/Cmd-U), select all, paste — or load / drag in a saved .html file. Whole page or just the JSON-LD blocks, either works.

Page URL (optional — resolves relative @ids like #person) Page source

Load file…

About page

Same again for the about page — the page most likely to carry the Person.

Mirror Test v0 — FoundFacts internal tooling. Reads application/ld+json blocks only (microdata and RDFa are not parsed; a page using those will look emptier here than it is — check the raw source if a result seems too bare). Everything runs locally in this browser: pasted HTML is never uploaded anywhere. Ideal sets are DRAFTS pending Crys's review — edit the IDEALS block in this file's source.
