Ontopoly is a Topic Maps editor that lets you incrementally design your Topic Maps ontology using a user-friendly web interface. The ontology then drives a web-based user interface for populating the topic map with instance data. Thus, it is possible to build an entire topic map stored either in file or a database using Ontopoly.

The instance editing user interface is configurable, and can be set up to present reduced views of the data to users, thus reducing the amount of clutter and confusion for authors.

In addition, Ontopoly is embeddable inside other applications, so that it is possible to add Topic Maps editing capabilities to other applications (such as content management systems).

The screenshot below shows the user interface for editing an instance topic, in this case an instance of the topic type "Album" (as in CD recording):
