About JSON to RDF Converter

Convert JSON data to RDF (Resource Description Framework) format with support for Turtle, N-Triples, and RDF/XML serializations. Perfect for semantic web applications, linked data, and knowledge graphs.

Key Features

  • Multiple RDF Formats: Turtle (.ttl), N-Triples (.nt), and RDF/XML (.rdf)
  • Custom Base URI: Configure your own namespace and base URI
  • Type Annotations: Optional rdf:type declarations
  • Nested Objects: Handles complex nested JSON structures
  • Arrays Support: Converts JSON arrays to multiple RDF triples
  • Data Types: Preserves strings, numbers, booleans with XSD types
  • File Upload: Upload JSON files directly or paste data
  • Instant Preview: Real-time conversion as you type

How to Use

  1. Input JSON Data: Paste your JSON data or upload a .json file
  2. Configure Options: Select RDF format, base URI, and namespace prefix
  3. Review Output: The RDF triples update automatically
  4. Copy or Download: Use the Copy or Download button to save your RDF file
  5. Use in Applications: Import into triple stores, SPARQL endpoints, or semantic applications

Example Conversion

JSON Input:

{
  "name": "John Doe",
  "email": "john@example.com",
  "age": 28
}

RDF Output (Turtle):

@prefix ex: <http://example.org/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

ex:resource rdf:type ex:Resource .
ex:resource ex:name "John Doe" .
ex:resource ex:email "john@example.com" .
ex:resource ex:age "28"^^xsd:integer .

RDF Format Options

  • Turtle: Human-readable format with prefixes and compact syntax
  • N-Triples: Simple line-based format with full URIs
  • RDF/XML: XML-based format for maximum compatibility

Common Use Cases

  • Semantic Web: Create linked data resources for the semantic web
  • Knowledge Graphs: Build knowledge graphs from JSON data
  • Triple Stores: Import data into RDF databases like Apache Jena, Virtuoso
  • SPARQL Queries: Generate RDF data for SPARQL endpoint testing
  • Ontology Development: Create instance data for ontologies
  • Data Integration: Convert JSON APIs to RDF for integration

XSD Data Type Mapping

  • String: JSON strings → plain literals
  • Integer: JSON integers → xsd:integer
  • Float: JSON decimals → xsd:double
  • Boolean: JSON booleans → xsd:boolean
  • Null: JSON null → "null" literal
  • Array: JSON arrays → multiple triples with same predicate
  • Object: JSON objects → nested resources with blank nodes

Best Practices

  • Use Meaningful URIs: Choose descriptive base URIs that represent your domain
  • Consistent Namespaces: Use standard namespace prefixes (ex, foaf, dc, etc.)
  • Include Types: Enable rdf:type for better semantic clarity
  • Validate Output: Use RDF validators to ensure correctness
  • Choose Format: Use Turtle for readability, N-Triples for simplicity

RDF Tools & Resources

  • Triple Stores: Apache Jena, Virtuoso, GraphDB, Blazegraph
  • SPARQL Endpoints: Query RDF data using SPARQL query language
  • Validators: W3C RDF Validator, RDF Translator
  • Ontologies: FOAF, Dublin Core, Schema.org vocabularies

Privacy & Security

All conversions happen locally in your browser. Your JSON data is never uploaded to any server, ensuring complete privacy and security.
