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.

Load and does nothing then :(

This extension is great at providing insight into the RDF data that is contained in websites. 𝕄𝕚𝕟𝕠𝕣 𝕓𝕦𝕘 𝗧𝗵𝗲 𝗶𝘀𝘀𝘂𝗲: In a turtle file, expanding prefixed node names fails if a prefix URL is missing a "/" after the host part, as in here: "@𝚙𝚛𝚎𝚏𝚒𝚡 𝚜𝚌𝚑𝚎𝚖𝚊: <𝚑𝚝𝚝𝚙𝚜://𝚜𝚌𝚑𝚎𝚖𝚊.𝚘𝚛𝚐>.". So "𝚜𝚌𝚑𝚎𝚖𝚊:𝚌𝚘𝚗𝚝𝚎𝚗𝚝𝚞𝚛𝚕" resolves to "𝚑𝚝𝚝𝚙𝚜://𝚜𝚌𝚑𝚎𝚖𝚊.𝚘𝚛𝚐𝚌𝚘𝚗𝚝𝚎𝚗𝚝𝚞𝚛𝚕/", which is not what we want. 𝗧𝗵𝗲 𝗳𝗶𝘅: Easy, if the path of the prefix URL is empty then act as if the path part were "/". (And: if the RDF-related specs don't mandate this behaviour, then maybe the specs should be fixed as well !)

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.

Cool, I've been looking for that

Tyson Graaff2018年2月12日

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.

Very helpful tool for seeing structured data on a web page.

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!

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.
