Linked data

Our server fetches the HTML of the URL; your browser then looks for the script blocks with application/ld+json and reads each block as a search engine finds it: blocks in document order, inside them the nodes with an @type, and in those nodes the properties that stand with them — including what is nested in @graph or in another node.

The failures are previewed too: a block that does not parse as JSON gets the place where it broke (line and column when the parser names them), an empty block is called empty, and JSON without a single @type is named instead of half-read. JSON-LD that stands here is a promise the page makes to a search engine; this tool shows that promise, word for word.

The preview builds on Link preview: the same endpoint, the same HTML, the same limits — it performs no new measurement. It does make what already stands there readable: types, names, properties and the grading of what is missing.
