About MediaWiki to RDF Converter

Convert MediaWiki table markup to RDF (Resource Description Framework) format for semantic web applications, linked data, and knowledge graphs. RDF is a W3C standard for representing information about resources in the web.

Key Features

  • Multiple RDF Formats: Support for Turtle, RDF/XML, and N-Triples serializations
  • Automatic Type Detection: Detects numeric values and URIs automatically
  • Custom Base URI: Configure the base URI for your RDF resources
  • Semantic Web Ready: Generate W3C-compliant RDF for linked data applications
  • Property Sanitization: Automatically converts headers to valid RDF property names
  • MediaWiki Parser: Accurately parses MediaWiki table syntax
  • File Upload: Upload .wiki files directly
  • Instant Preview: Real-time conversion as you type
  • Copy & Download: Easy export in .rdf, .ttl, or .nt formats

How to Use

  1. Input MediaWiki Table: Paste your MediaWiki table markup or upload a .wiki file
  2. Select RDF Format: Choose between Turtle, RDF/XML, or N-Triples
  3. Configure Base URI: Set the base URI for your RDF resources
  4. Review Output: The RDF output updates automatically
  5. Export: Copy to clipboard or download as .rdf, .ttl, or .nt file

RDF Formats

  • Turtle (.ttl): Human-readable format with compact syntax and prefix support
  • RDF/XML (.rdf): XML-based format, widely supported in legacy systems
  • N-Triples (.nt): Simple line-based format, easy to parse and process

Example Conversion

MediaWiki Input:

{| class="wikitable" border="1"
! Name !! Age !! City !! Department
|-
| John Doe || 28 || New York || Engineering
|-
| Jane Smith || 34 || London || Marketing
|}

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" ;
  ex:department "Engineering" .

Common Use Cases

  • Linked Data: Create linked data resources for the semantic web
  • Knowledge Graphs: Build knowledge graphs from Wikipedia tables
  • Ontology Development: Generate RDF data for ontology testing
  • Data Integration: Convert wiki data for RDF-based integration systems
  • SPARQL Queries: Prepare data for SPARQL query endpoints
  • Triple Stores: Import data into RDF triple stores like Apache Jena, Virtuoso
  • Semantic Search: Enable semantic search capabilities
  • DBpedia Integration: Convert Wikipedia tables to DBpedia-compatible format

RDF Concepts

  • Resources: Each row becomes an RDF resource with a unique URI
  • Properties: Column headers become RDF properties in the vocabulary namespace
  • Literals: Cell values become RDF literals with appropriate datatypes
  • Triples: Each cell creates a subject-predicate-object triple
  • Namespaces: Uses standard RDF, XSD, and custom vocabulary namespaces

Type Detection

The converter automatically detects data types:

  • Numeric Values: Assigned xsd:decimal datatype
  • URIs: Values starting with http:// or https:// become resource references
  • Text: All other values become string literals

MediaWiki Table Syntax

Supports standard MediaWiki table markup:

  • {|: Table opening with optional attributes
  • ! Header: Exclamation mark for header cells (separated by !!)
  • |-: Row separator
  • | Data: Pipe for data cells (separated by ||)
  • |}: Table closing

Turtle Format Features

  • Compact and human-readable syntax
  • Prefix declarations for shorter URIs
  • Semicolon notation for multiple properties
  • Datatype annotations with ^^
  • Widely used in semantic web applications

RDF/XML Format Features

  • XML-based serialization
  • Compatible with XML tools and parsers
  • Namespace support
  • rdf:about for resource identification
  • rdf:resource for URI references
  • rdf:datatype for typed literals

N-Triples Format Features

  • Simple line-based format
  • One triple per line
  • Full URIs (no prefixes)
  • Easy to parse and stream
  • Ideal for large datasets

Integration Examples

  • Apache Jena: Import into Jena TDB or Fuseki
  • Virtuoso: Load into OpenLink Virtuoso triple store
  • GraphDB: Import into Ontotext GraphDB
  • RDF4J: Use with Eclipse RDF4J framework
  • SPARQL Endpoints: Query with SPARQL 1.1
  • DBpedia: Compatible with DBpedia data model

Wikipedia Integration

Perfect for converting Wikipedia tables to RDF:

  • Extract data from Wikipedia articles
  • Convert to DBpedia-compatible format
  • Build custom knowledge graphs from Wikipedia
  • Integrate with Wikidata
  • Create semantic annotations

Tips for Best Results

  • Use meaningful column headers that will become property names
  • Choose Turtle format for human readability
  • Use RDF/XML for XML-based workflows
  • Use N-Triples for large-scale data processing
  • Configure a meaningful base URI for your domain
  • Include URIs in cells to create linked data connections
  • Validate output with RDF validators before deployment
  • Consider using owl:sameAs for linking to external resources

Privacy & Security

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