  • A watchlist page (Special:SemanticWatchlist) listing changes to properties watched by the user.
  • Per-user optional email notification per edit that changes properties.
  • Integration with user preferences to allow users to specify which watchlist groups they want to follow, and if they want to receive emails on changes.
  • Special:WatchListConditions as administration interface for watchlist groups.

  • API modules to add, modify and delete the watchlist groups.
