The TMHarvest library is based on TM4J and provides a convenient way to automatically generate topic maps from different data sources. A rules files with embedded templates (written in XML) defines from which data sources topic map constructs should be taken into account, as well how new or existent topics should be associated.
mod_sphinx is an Apache module which intercepts output bound for the client, whether it be from files served by the same Web server, files sent via reverse proxying, or files delivered by transparent forward proxying (outbound proxying, as in your browser's proxy setting). It opens the text and replaces a word with another word or phrase. When in regular proxy mode, it cannot modify SSL content since Apache cannot decrypt that (it would be a protocol violation).
