Revision as of 15:37, 14 November 2007

Wandora project is a collection of layers and general Wandora settings. Project is saved with File > Save project top menu bar option. Project is loaded to Wandora with File > Open project option found in top menu bar. Wandora project's file extension is wpr. Opening project file deletes current project. Consider using File > Merge project to keep the existing topic maps in Wandora.

Internal structure of Wandora project file

Wandora project file is a zip archive containing configuration file options.xml and layer folders layer0, layer1, layer2, etc. one folder for each layer. Layer folder contains a topic map file in XTM format or XML configuration file. Memory based topic maps generate topic map file topicmap.xtm while database topic maps generate only configuration file dboptions.xml used to establish the database connection.

NOTE: Project file with a database layer contains database user and password used to establish the database connection. Sharing the project file shares also the database settings!!!

Here is an example of project's options.xml. Project contains two layers both containing memory topic maps. Second layer is read-only.

<?xml version="1.0" encoding="UTF-8"?>
<options>
  <layer0>
     <visiblity>true</visiblity>
     <readonly>false</readonly>
     <name>base.xtm</name>
     <selected>true</selected>
     <type>com.gripstudios.applications.wandora.topicmap.memory.TopicMapImpl</type>
  </layer0>
  <layer1>
     <visiblity>true</visiblity>
     <readonly>true</readonly>
     <name>out.ltm</name>
     <type>com.gripstudios.applications.wandora.topicmap.memory.TopicMapImpl</type>
  </layer1>
</options>
