How to correctly create and use open educational resources, which focuses on wikisystems.

Navigation through wikis takes place mostly via internal wikilinks. MediaWiki wikilinks implement the detection of a page’s existence, in which the link is blue if the target page exists on a local wiki and is red if this is not the case. If a user clicks on a red link, a call to create an article with this title appears. Thanks to page existence detection, it is practical for users to create “wikified” articles – i.e. articles containing links to other relevant subjects – without these other articles yet existing.
