This extension provides a new MediaWiki parser function named "isin". It expects one argument, the name of the article where the current article "is in".

During parsing of the wiki markup, some few data related to the isin function's argument are generated and stored in the parser cache.

When the article is displayed, its HTML code has to be built from the parser cache. The BreadCrumbs extension has a method triggered by the 'OutputPageParserOutput' hook. Here, the complete bread crumb trail is build up by starting with the article's own isin and retrieving subsequently higher level isin data from the corresponding parser caches. The HTML code of the bread crumb trail is added to the page's subtitle.

Use of the isin keyword adds a breadcrumb trail under the title. Here shows the Vector 2022 skin.
