Wandora BasicsTopic tree navigator on the left side

Customizable, can make several trees

Opened topic fills most of the screenDouble click on topics to open themType in fields to edit valuesUse menus do other tasks

Right mouse button Context menu→Layers at lower left corner

12

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!!!!!!

13

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
