The Ontopia Navigator Framework is a framework for rapid development of J2EE compliant web applications using topic maps.
The Navigator Framework is an XML-based scripting language optimised for topic map application development. Using this language, developers can easily collect information from the topic map, perform complex operations like scope filtering, name selection, etc, and output the results in HTML, XML, WML, or any other format. The language is carefully designed to be easy to learn, powerful, and extensible. It can be combined with Java code if desired, but this is necessary only in rare cases.
The Navigator Framework is based on J2EE, using the Java Servlets and Java Server Pages (JSP) technologies. It is built on the Ontopia Topic Map Engine, and consists of a set of JSP tag libraries, and a Java API. Applications built with the Navigator Framework can be deployed in any J2EE container. We have used the Apache Foundations Tomcat server as the development platform, and have a test suite for the Navigator Framework that can be used to quickly verify that the framework works correctly in any J2EE environment. It is known to work with the Resin application server.
