OpenLink Structured Data Sniffer

OpenLink Structured Data Sniffer is a browser extension that discovers and presents metadata embedded in HTML documents. It is suitable for Web Extensions-compatible browsers such as Google Chrome, Microsoft Edge, and Opera. The extension supports the discovery and processing of structured data islands that are published with notations such as Microdata, RDFa, JSON-LD, RDF-Turtle, RDF-XML, CSV, and JSON. It simplifies the understanding of the content of an HTML document through its metadata for end users and developers. After installing the extension, the OSDS icon becomes visually active upon arrival on a page, indicating a metadata discovery. A click on the icon displays a presentation of the transformed metadata.
