Abstract

The goal of this tutorial is to present some advanced features of the Lua programming language and of the libraries provided by MediaWiki. Between other things, object oriented programming, JSON support, interaction with wiki and Wikibase content will be presented.

Collaborative notes of the session

Use "mw.ustring" instead of "string" when working with strings in Lua to get Unicode support (string only work in ASCII).

Utility functions (MediaWiki):

   * mw.addWarning
   * mw.loadData

Microdata (see page 45 in slides)
