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.
How is it used?
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.

- (2023-04-04) Joshua Hintze: Unfortunately this plugin adds popup and snackbar items to the DOM. You can see this by inspecting DOM and seeing super_links_popup items and osds_popup junk get added to your DOM in your browser.
- (2021-11-12) Ron Henry: Cool, I've been looking for that
- (2019-05-09) Aaron Bradley: Hands down the best-in-class extension for inspecting a page for the presence or absence of structured or semi-structured data.
- (2018-02-12) Tyson Graaff: Just what I was looking for. Let's me know if my JSON-LD is on the page and I can check it in an easy to read format.
- (2017-04-20) Michael Andrews: Very helpful tool for seeing structured data on a web page.
- (2016-06-21) Rich Missey: Dug around for over an hour trying to find an extension that could display JSON-LD data pulled through an AJAX call. Thought I was going to have to write the thing myself!
- (2015-12-22) I've been enjoying using this extension to see what markup has been used on pages. I've recommended that others install and use this extension as well. It makes understanding what is going on upon pages easier to glean, in a helpful way.
- (2015-12-22) Barbara Starr: I have long been awaiting the arrival of a chrome extension that can effectively detect json-ld and display it in my chrome browser as an alert/extension with the relevant data. This tool detects not only json-ld, but all semantic markup formats/syntaxes (Microdata, rdfa, etc). The UI is elegantly and well thought out in terms of the fact that there are tabs for each syntax. I love this extension and highly recommend it!! As a caveat, it has other interesting features I have not yet fully explored, but that does not detract in any way from my above statements.
