Status of the GAUDI Event—Processing Framework

The GAuDI architecture and framework are designed to provide a comon infrastructure and environment for simulation,filtering,reconstruction and analysis applications.Initially developed for the LHCb experiment,GAUDI has been adopted and extended by the ATLAS experiment and adopted by several other experiments including GLAST and HARP.we describe the properties and concepts embodied by GAUDI and recent functionality additions and how the project has evolved from a product developed by a tightly-knit team in a single site,to a collaboration between multiple teams at geographically dispersed sites,based loosely on open source concepts.We describe the management infrastructure as well as how we accommodate experment -specific extensions and adaptations as well as an experiment-neutral kernel.
