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.
==Related Concepts==
MediaWiki also has the function permanent links in the standard version, with which you can link to a specific article version.
It is also possible to manually assign a document number to an article. So that this can be read and used, one can work with semantic functions.
