Topic map standard defines a merge operation between identical topics. Merge operation is extremely powerful as it allows incremental knowledge building. Knowledge packets addressing same topics superposition. The only problem with merge rules is that the source of topic changes is lost. You can't recognise which source assigned which topic element. Backtracking the merge changes is essential to ensure trust between knowledge sources and knowledge aggregator.
Wandora supports layered topic maps. Layered topic map contains one or more topic maps stacked into an ordered array. Wandora allows you to add and delete topic maps in the layer stack. You can also make topic map layer invisible and lock layer if you decide not to change layer's contents.
Wandora's layer stack locates in bottom left corner. When you start Wandora, application reads topic map from conf/wandora.xtm and creates the layer Base for it.
