Dragon Breath is the name of a generic development and application framework that is heavily based on PostgreSQL and PHP. It contains different layers which wrap business logic, data, and any graphical interface. It opens up and eases development in the field of graphical user interfaces and data management. The interface layer is built upon XSLT rendering, which allows the rendering of displays for different interfaces like Web browsers, PDAs, mobile phones, and others. The database layer depends on PostgreSQL's features and allows a common exchange of data with any kind of data structure. It even contains built in sanity checks for data integrity.
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.
GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like DPX, DICOM, BMP, GIF, JPEG, JPEG-2000, PDF, PNG, PNM, SVG, and TIFF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X.
