OpenLink Structured Data Sniffer: Revealing Embedded Metadata in HTML Documents

The OpenLink Structured Data Sniffer (OSDS) is a browser extension for Web Extensions compliant browsers like Chrome, Microsoft Edge, and Opera. It allows users to discover and analyze structured metadata embedded within HTML documents. OSDS supports various notations such as Microdata, RDFa, JSON-LD, RDF-Turtle, RDF-XML, CSV, and JSON.

This extension is valuable for both end-users and developers as it simplifies the process of understanding the content and purpose of HTML documents. It helps Digital Brand Managers, Digital Content Managers, and Semantic Search Engine Optimization (SSEO) practitioners analyze how metadata affects Search Engine Results Pages (SERPs) placements.

To use OSDS, simply install the extension on your browser and visit a page of interest. Upon arrival, the OSDS icon will be activated, indicating metadata discovery. Clicking on the icon will present you with a transformed presentation of the discovered metadata.
