The vanilla version is powered by the database of VMaNGOS.
The addon is not designed to be a quest- or tourguide, instead the goals are to provide an accurate in-game version of AoWoW or Wowhead. If one of the items is not yet available on your realm, you'll see a in front of the name. It ships with a GUI to browse through all known objects. The addon reads questobjectives, parses them and uses its internal database to plot the found matches on the world- and minimap.
It helps players to find several ingame objects and quests. This is an addon for World of Warcraft Vanilla (1.12) and The Burning Crusade (2.4.3).
