Merging in Topic Maps
Topic Maps specify clear topic merging rules
If two topics have same subject locator, subject identifier or same base name they are the same topic
Makes it possible to merge several topic maps into a larger topic mapAlso need to be careful not to accidentally merge topics!!!!!!

Topic Map Layers
In Wandora you can organize your data in several topic maps arranged in a layer stack
Keep different kinds of data separateManage data visibilityData can come from different source
In the editor, and when publishing, the layers will look like one big merged topic map
