The Navigator Framework is a JSP tag library and Java API which enables developers to quickly and easily develop web-based interfaces based on Topic Maps using Ontopia. The tag library generates no HTML on its own, giving developers complete freedom to produce exactly the type of output they wish. The tag library is based on the tolog query language, and is quite similar to XSLT and the JSTL core tag library. It is also integrated with the JSTL core tag library, allowing interaction between the two sets of tag libraries and the use of the JSTL expression language.

Below are some screenshots from applications developed with the tag library.
