This document discusses reconstructing past versions of pages on MediaWiki by programmatically accessing historical data stored in the system. It describes how the Memento MediaWiki extension currently handles retrieving old revisions of articles and templates. Prototypes have been created for embedding past images as well. While the data exists, there is currently no way for extensions to access or render prior embedded JavaScript and CSS. The goal is to provide a uniform solution for accessing historical versions of all page resources according to the Memento protocol standard.
