We write articles on Blog. Many write them on WordPress.org CMS. A plugin rather inbuilt functionality should be present in the CMS which would show at start of article after the Article Heading about what kind of article it is, when it was created, when it was last updated. To say it should be something like Wikipedia.
It could be something like: Article is final or Needs Updation or Needs Reference or Would be Updated etc. If an author thinks that he wants to publish the article with the information he has till the time of writing the article then it can be mentioned as ‘Needs Updation’. This along with dates should be publicly visible.
