Memory topic map

Memory topic map is a topic map construct kept in computer's memory during edit time. Memory topic map is probably the most common topic map construct Wandora user requires. Memory topic map requires no external initialization but is ready after creation.

Memory topic map can hold thousands of topics and associations. Actual limitations depend on the amount of memory you give to the Java Runtime Environment. Wandora includes four different startup scripts with different memory footprint. Default script gives JRE 750M enought to hold topic maps with ~50 000 topics and ~100 000 associations.

Creating Memory Layer

To create a memory topic map layer select Layers > New layer and choose Memory as the layer type. Configuring new memory layer is very easy. Just enter layer's name and choose to import XTM topic map file to created layer, or not. If you decide not to import any topic map, the created layer will be empty. Below is an example of memory layer configuration panel.

You can also select to import Wandora's mini ontology conf/wandora_mini.xtm to the created layer. This mini map contains a set of Wandora's fundamental topics and associations. After layer creation you should see new layer at the left bottom of application window.

Letter M marks for a memory topic map layer. Letter D marks for a database topic map layer.
