JSON-LD metadata, as shown by the OpenLink Structured Data Sniffer extension

Conzept supports embeddeding JSON-LD information about topics into the page. This information may also use Wikidata-based augmentation. Note: Non-wikipedia datasources or other embedded-apps do not (yet) support setting/updating the JSON-LD information.

JSON-LD, together with a commonly used ontology such schema:WebPage from Schema.org, allows 'smart' semantic web agents to discover web metadata and make use of it, in a standardized and automated way.
