This FAQ answers the general Wandora questions. There exists separate FAQ for Wandora user also.


What is Wandora?

Wandora is a software application to build, edit, publish and visualize information graphs, especially topic maps. Wandora is written in Java and suits for

  • Collecting, combining, aggregating, managing, refining and publishing information and knowledge graphs
  • Designing information, information modeling and prototyping
  • Information mashups
  • Ontology creation and management
  • Mind and concept mapping
  • Language technology applications

  • Data journalism
  • Open data projects
  • Linked data projects

See features for more complete list of Wandora's capabilities. As listed application areas sound very wide you may want to see also real-life projects for implementation ideas.

What Wandora is NOT?

  • Wandora is NOT a wiki. We use wiki only for documentation purposes.
  • Wandora is NOT an RDF/RDFS/OWL application. Although Wandora reads many kinds of RDF files, Wandora's internal data model is Topic Maps. This also means that Wandora is not strictly speaking a semantic web application.
  • Wandora is NOT a content management system (CMS). Although Wandora shares many features with CMS's, Wandora should not be seen as a modern CMS such as Drupal or Joomla.
  • Wandora is NOT a database. Although Wandora contains a graph database, Wandora should not be seen as a pure database application nor any specific database.
  • Wandora is NOT a software library. Wandora is a self standing application with a graphical user interface.

Is there any real-life examples where Wandora is used?

One of the best examples of live web sites using Wandora is The Art Collections of Finnish National Gallery. It sits on top of Apache Tomcat and Wandora's Modules framework. All site content is stored in four layered topic maps. Similar site built with Wandora is The Art Collections of Finnish State Art Commission.
