IA² Navigator

Inspect the structured meaning carried directly by an HTML document. IA² Navigator reads HTML/RDF in the current page and presents its statements, named graphs, vocabularies, and exact source carriers. Select the toolbar action on any supported page to open the Navigator and follow meaning back to the visible document. HARE resource envelopes open into a verified file workspace. The extension derives the inventory from the envelope manifest, verifies byte length and SHA-256 integrity before preview or download, and keeps HTML previews sandboxed. To recognize HARE envelopes automatically, the extension reads the top-level HTML and URL of every eligible page locally. On an ordinary page it adds no automatic interface. It does not transmit inspected page content, URLs, browsing history, or usage analytics to IA² or Inferal. Features: - Inspect RDF statements and named graphs extracted from HTML. - Search terms and filter by vocabulary namespace. - Reveal the HTML element that carries a selected statement. - Follow advertised RDF sources only when you choose to retrieve them. - Browse and verify resources embedded in HARE envelopes. - Observe semantic DOM changes while the Navigator is open. IA² Navigator is open source and implements the exploratory IA² HTML/RDF and HARE proposals. These proposals are not established standards.
