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>org.wandora.topicmap.memory.TopicMapImpl</type>
  </layer0>
  <layer1>
     <visiblity>true</visiblity>
     <readonly>true</readonly>
     <name>out.ltm</name>
     <type>org.wandora.topicmap.memory.TopicMapImpl</type>
  </layer1>
</options>
