These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.

Wiki markup, also known as wikitext language and wikicode, is a lightweight markup language used to write pages at wiki-based websites (such as Wikipedia) that is a simplified alternative/intermediate to HTML. Its ultimate purpose is to be converted by wiki software into HTML, which, in turn, is served to web browsers. It was originally created in 1995 to format pages on the original wiki site, WikiWikiWeb.
There is no commonly accepted standard wikitext language. The grammar, structure, justification, keywords and so on depend on the particular wiki software used on the particular website. For example, all wikitext markup languages have a simple way of hyperlinking to other pages within the site, but there are several different syntax conventions for these links. Many wikis, especially the earlier ones, used CamelCase to mark words that should be automatically linked. In MediaWiki, this convention was replaced with the [[…]] notation, which Wikipedia calls "free links".
Different Wiki programs may support use of different sets of HTML elements within wikitext. In some cases, permitted HTML elements may be configured by individual wiki sites. MediaWiki supports many common HTML tags.
Creole is an effort for a "common wiki markup language to be used across different Wikis".[1] There are several wiki engines that have implemented Creole.[2] Version 1.0 of the specification was released in July 2007.[3] It is not supported by MediaWiki.
