What is OpenLink Structured Data Sniffer?
OpenLink Structured Data Sniffer is a powerful Firefox add-on that enables the discovery and handling of structured metadata embedded within HTML pages. It supports various notations including POSH, Microdata, JSON-LD, RDF-Turtle, and RDFa. Beyond HTML, it allows the browser to natively render JSON-LD and RDF-Turtle documents. With features like a Web Service Console, copy and paste functionality, and support for data visualization, it simplifies interaction with RESTful APIs and facilitates exporting and reusing structured data. Additionally, it provides seamless integration with SPARQL-accessible Knowledge Graphs, allowing one-click saving of structured data and connecting words or phrases to entity descriptions across knowledge graphs.

The OpenLink Structured Data Sniffer is a "hidden gem" that simplifies the exploration of structured data on webpages. It even lets you navigate linked data from any URI containing an RDF model (accepting OWL, XML, TTL, HTML RDFa microdata, JSON-LD and more). It's user-friendly and fast, working on large OWL models such as D3FEND and those from the Financial Industry Business Ontology (FIBO). Looking forward to seeing the OpenAI integration continue to be developed!
