User browses to `organization.html`\n2. Server returns `Content-Type: text/html`\n3. rdflib Fetcher doesn't know how to parse HTML\n4. Empty store, nothing renders\n\n**Expected behavior:**\n1. User browses to `organization.html`  \n2. solid-shim detects HTML response\n3. Extracts `\u003cscript type=\"application/ld+json\"\u003e` content\n4. Parses JSON-LD into store\n5. Renders with appropriate pane (or @view if specified)\n\n## Background\n\nJSON-LD data islands are part of the JSON-LD spec and widely used (Google's structured data, schema.org markup, etc.). The browser should handle them natively.\n\n## Proposed Solution\n\nHook into rdflib's Fetcher or add a custom handler:\n\n```javascript\n// When fetching a URL\nconst response = await fetch(url)\nconst contentType = response.headers.get('content-type')\n\nif (contentType?.includes('text/html')) {\n  const html = await response.text()\n  const doc = new DOMParser().parseFromString(html, 'text/html')\n  const jsonLdScript = doc.querySelector('script[type=\"application/ld+json\"]')\n  \n  if (jsonLdScript) {\n    const data = JSON.parse(jsonLdScript.textContent)\n    parseJsonLdToStore(data, url, store)\n    // Render with @view or type-based pane\n  }\n}\n```\n\n## Related\n\n- json-os/json-os.github.io#1 - The @view proposal\n- solid-shim#4 - @view predicate support","author":{"url":"https://github.com/melvincarvalho","@type":"Person","name":"melvincarvalho"},"datePublished":"2026-01-06T22:51:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/5/solid-shim/issues/5"}
