Unique page ID

In web technology, a unique page ID is a number assigned to a page in order to address it uniquely. This makes it possible to change the title of a page at any time, while the links to this page do not have to be changed.

IDs in MediaWiki

MediaWiki works in the standard without a single page ID. Here the title is unique and can only be assigned once. This prevents the parallel existence of identical page titles. The users should gather their knowledge to a term in one place.

However, the Wiki internally carries a numeric ID, which is not displayed. In order to make this ID visible and usable, an extension must be programmed.
