How to export topic map in Wandora

Exporting topic map in Wandora starts with

• Selecting File > Export > Export topic map... in top menu bar.
• Selecting Layers > Export layer > Export topic map... in top menu bar.
• Selecting Export layer > Export topic map... in layer context menu.

First method exports all available layers merged together. Last two methods export only the topic map in current layer. You are requested file name for the exported topic map. If your file name has ltm extension Wandora exports topic map in LTM format. Otherwise Wandora exports topic map in XTM format.

Merged export

Merged export starts with File > Export > Export topic map.... Merged export creates a topic map containing topics and associations from all visible layers. Exported topic map may contain multiple identical topics and associations as the export does not keep book of already exported topics and associations. To remove these redundant topics and associations import the topic map back to Wandora, make a association consistency check, and export the topic map again.

Another method to create a consistent topic map without redundant topics and associations is to merge all layers and export the resulting single layer topic map.

Layer export

Layer export starts with Export layer > Export topic map.... Exporting single layer when you have multiple layers available exports literally the selected layer. For example base names and subject identifiers inherited from merged topics are not included in the export.

Exporting same layer multiple times may result a topic map file with slightly different file size. Different file size is a consequence of different XTM identifiers a topic may receive during export.
