SILGraphite (formerly OpenGraphite) is a project within SIL's Non-Roman Script Initiative and Language Software Development groups to provide extensible cross-platform rendering capabilities for complex non-Roman writing systems. It consists of a rule-based programming language, Graphite Description Language (GDL), that can be used to describe the behavior of a writing system, a compiler for that language, and a rendering engine that can serve as the backend of a text processing application. SILGraphite renders TrueType fonts that have been extended by means of compiling a GDL program. It is currently being integrated into Gecko/Mozilla through the SILA project, a GNU/Linux port is also underway, and there are plans for OpenOffice.org and Abiword integration.
