JSON-LD First

JSS is a JSON-LD native implementation. Unlike traditional Solid servers that treat Turtle as the primary format, JSS:

  • Stores everything as JSON-LD - No RDF parsing overhead
  • Serves JSON-LD by default - Web apps consume responses directly
  • Content negotiation is optional - Enable Turtle with --conneg when needed

Why JSON-LD?​

  1. Performance - JSON parsing is native to JavaScript
  2. Simplicity - JSON-LD is valid JSON, works with any tooling
  3. Web-native - Browsers understand JSON natively
  4. Semantic web ready - JSON-LD is a W3C standard RDF serialization

When to enable content negotiation​

Enable --conneg when:

  • Interoperating with Turtle-based Solid apps
  • Serving data to legacy Solid clients
  • Running conformance tests
# JSON-LD only (fast, default)
jss start

# With Turtle support
jss start --conneg
