Property:Modification date
From DCPR (en)
Change propagation updates are pending (21 jobs estimated) and it is recommended to wait with modifications to a property until the process has been finalized to prevent intermediary interruptions or contradictory specifications.
"Modification date" is a predefined property that corresponds to the date of the last modification of a subject and is provided by Semantic MediaWiki. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.
