About XML to RDF Converter

Convert XML data to RDF (Resource Description Framework) format for semantic web applications, knowledge graphs, and linked data. Supports multiple RDF serialization formats.

Key Features

  • Multiple RDF Formats: Turtle (.ttl), RDF/XML (.rdf), N-Triples (.nt)
  • Automatic Type Detection: Recognizes numeric values and URIs
  • Custom Base URI: Configure resource URI namespace
  • Property Sanitization: Converts XML tags to valid RDF property names
  • W3C Compliant: Follows RDF standards and best practices
  • File Upload: Upload .xml files directly
  • Copy & Download: Easy export in chosen RDF format

How to Use

  1. Input XML Data: Paste your XML data or upload an .xml file
  2. Select RDF Format: Choose between Turtle, RDF/XML, or N-Triples
  3. Configure Base URI: Set the namespace for your resources (optional)
  4. Review Output: The RDF data generates automatically
  5. Copy or Download: Use the Copy or Download button to save your RDF file

RDF Format Options

  • Turtle (.ttl): Human-readable, compact syntax with prefixes
  • RDF/XML (.rdf): XML-based format, widely supported
  • N-Triples (.nt): Simple line-based format, easy to parse

Supported XML Structures

The converter recognizes several common XML table patterns:

  • <table><row>...</row></table>: Standard table structure
  • <data><record>...</record></data>: Data records pattern
  • <records><record>...</record></records>: Records collection
  • Repeated Elements: Any root with repeated child elements
  • Attributes: Also supports attribute-based data

Type Detection

The converter automatically detects data types:

  • URIs: Values starting with http:// or https:// become resource references
  • Numeric: Integer and decimal values get xsd:decimal datatype
  • String: All other values are treated as literal strings

Example Conversion

XML Input:

<?xml version="1.0" encoding="UTF-8"?>
<data>
  <record>
    <Name>John Doe</Name>
    <Age>28</Age>
    <City>New York</City>
  </record>
  <record>
    <Name>Jane Smith</Name>
    <Age>34</Age>
    <City>London</City>
  </record>
</data>

Turtle Output:

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

<http://example.org/data/record1>
  ex:name "John Doe" ;
  ex:age "28"^^xsd:decimal ;
  ex:city "New York" .

<http://example.org/data/record2>
  ex:name "Jane Smith" ;
  ex:age "34"^^xsd:decimal ;
  ex:city "London" .

Common Use Cases

  • Semantic Web: Create linked data for web applications
  • Knowledge Graphs: Build structured knowledge representations
  • Triple Stores: Import data into RDF databases (Virtuoso, Jena, etc.)
  • SPARQL Queries: Enable semantic queries on your data
  • Linked Open Data: Publish data in standard RDF formats
  • Ontology Development: Create instance data for ontologies

RDF Benefits

  • Interoperable: Standard format for data exchange
  • Extensible: Easy to add new properties and relationships
  • Queryable: Use SPARQL for complex queries
  • Linked: Connect data across different sources
  • Semantic: Machine-readable meaning and relationships
  • Standards-Based: W3C recommendations ensure compatibility

Property Name Sanitization

XML tags are automatically converted to valid RDF property names:

  • Converts to lowercase with underscores
  • Removes special characters
  • Ensures names start with letters or underscores
  • Handles duplicate names appropriately

Privacy & Security

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