About

Spark is a JavaScript library that allows the simple integration of data from all over the Web in any HTML page, using a rich set of visualizations. This extension enabled embedding of spark mashups using <spark /> tags.

Spark as described on the Spark website:

Spark is a library that enables HTML authors to create mashups more easily than ever before. Using standard Web technologies like SPARQL, RDF, HTML5, and JavaScript, Spark can query external knowledge sources (so called triple stores or SPARQL endpoints), and then visualise the results.

With Spark, website developers can create visually appealing mashups without having to write a single line of JavaScript, but merely using some markup elements describing the source of the data that is to be shown, a query to select the appropriate data, and selecting one from an expandable set of visualisations and their parameters.

This MediaWiki extension, unsurprisingly titled Spark, adds a <spark> tag to MediaWiki which is equivalent to <div class="spark"> as described in the spark library documentation. All parameters (except the class="spark" one) can just be copied over between spark divs in web pages, and the <spark> tag in MediaWiki.

Feature overview

  • Visualization of data obtained via SPARQL queries.
  • Support for all Spark visualizations.
  • Use of the native Spark syntax, which can be copied from native spark divs to the spark tag and back.

Internationalization

Spark is fully internationalized. Translation of Spark messages is done through translatewiki.net. The translation for this extension can be found here. To add language values or change existing ones, you should create an account on translatewiki.net, then request permission from the administrators to translate a certain language or languages on this page (this is a very simple process). Once you have permission for a given language, you can log in and add or edit whatever messages you want to in that language.
