Data exchange

Semantic MediaWiki's ability to collaborate and exchange data with other web-services and websites is a vital therefore various exchange formats and extensions are provided to extend SMW's data interchange capability.

Exchange formats

RDF

Resource Description Framework (RDF) is a metadata data model specified by the World Wide Web Consortium where entity-relationship and resources are defined by a subject-predicate-object expressions. RDF statements are either a Uniform Resource Identifier (URI) or a blank node and serialized in a XML format.

Supported extensions and result formats:

• Semantic MediaWiki comes with a build-in functionality for RDF export
• Semantic Result Formats provides a Help:RDF format module to produce links to OWL files in RDF form

JSON

JavaScript Object Notation (JSON) is a text-based open standard designed data interchange and commonly used for importing web data into JavaScript applications. JSON is a subset of JavaScript and is often used in connection with Ajax applications.

Supported extensions and result formats:

• Semantic Result Formats provides an export module (see Help:JSON format)

OData

Open Data Protocol (OData) is an open web protocol specified by the Microsoft Open Specification Promise (OSP) supporting two formats for representing resources: the XML-based AtomPub format and the JSON format. More comprehensive information can be found here.

Supported extensions and result formats:

• Is not yet supported.

Other exchange formats

Help:KML format allows for export of queries geographical data in KML (Keyhole Markup Language) Help:CSV format UNIX-style Delimiter Separated Value format

Help:DSV format produces links to CSV files Help:RSS format produces links to RSS feeds

Data exchange extensions

mws:Extension:Spark a JavaScript library that allows the simple integration of data mws:Extension:RDFIO extended RDF import to a SPARQL endpoint mws:Extension:SparqlExtension integrates Semantic MediaWiki with a SPARQL endpoint via a web-service (Triple store, Joseki endpoint)

mws:Extension:External Data retrieve, filter, and format data from one or more sources (external URLs etc.) mws:Extension:LinkedWiki lets you reuse Linked Data in your wiki. You can get data from Wikidata or another source directly with a SPARQL query. Can also be used to query a SMW powered SPARQL endpoint in order to query data in the wiki with SPARQL instead of #ask.
