The BID software was designed to apply business rules to your email traffic. Business information can come from business applications, monitoring applications, or normal users requesting or providing data. The goal of the BID tool is to automate the dispatching of this information and to join a business-case with a responsible receiver. A receiver can be a human being or another BID server customized for a special business-case. The BID server was designed as a generic server using plugins to serve specific business-rules.

It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
Dragon Lair is a knowledge base system based on Topic Maps Technology. Data Elements are represented as topics and subjects and put into relationships with each other. Since these relations are data independent, Dragon Lair can be put on top of an existing database or be used as a graphical representation of a new data source. Dragon Lair "sits" directly upon the Dragon Breath framework for reliable and easy data manipulation, sanity check, and data exchange.
