XML to RDF Converter

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.

FAQs

• Which XML structures convert cleanly to RDF? XML with repeated record-like elements (for example, multiple <record> or <row> nodes) and consistent child tags works best for generating subject–predicate–object triples.
• Can I change the vocabulary from ex:? Yes. The output uses the ex: prefix and http://example.org/vocab/ by default, but you can search-and-replace these with your own ontology or vocabulary IRIs.
• How should I choose the base URI? Use a stable domain or namespace that represents your dataset, such as https://example.com/data/. Each record gets a unique URI based on this base.
• Does this tool handle nested XML? It focuses on table-like structures. Deeply nested XML may need preprocessing or flattening before conversion to RDF.
• Is any of the RDF generation done on a server? No. All parsing and RDF generation run locally in your browser, so your data remains private.
