It adds another panel to your Chrome DevTools, allowing you to see all this information at a glance, nicely grouped and in real time. - Results are displayed in their source code order. - The result list is always kept up-to-date. (If it seems stuck for any reason, you can press the reload button located at the upper right.) - The filter can be easily used by simply typing (the input doesn't need to be focused beforehand) - You can filter by multiple arguments using a comma `,` as a delimiter (e.g., "title, canonical"). - To display result options/actions, simply hover over its row.

OpenLink Structured Data Sniffer
What is it? The OpenLink Structured Data Sniffer (OSDS) is an extension for Web Extensions compliant browsers (e.g., Google Chrome, Microsoft Edge, Opera, and many others) that discovers Metadata embedded within HTML documents as Structured Data Islands and presents what's discovered using a Property Sheet presentation style. Currently, OSDS supports discovery and processing of Structured Data Islands published using notations such as Microdata, RDFa, JSON-LD, RDF-Turtle, RDF-XML, CSV, and JSON. Why is it important? It simplifies the process of understanding what a given HTML document is about, via its metadata, for both end-users and developers. For instance, it helps Digital Brand Managers, Digital Content Managers, and Semantic Search Engine Optimization (SSEO) practitioners understand what may or may not be affecting Search Engine Results Pages (SERPs) placements. Simply install the extension to your browser and then visit a page of interest. On page arrival, the OSDS icon will be visually activated thereby indicating metadata discovery; once the icon is clicked, you will be presented with a presentation of transformed metadata.
